|
20050408 Some minor updates to the wdc. Linux now doesn't complain |
| 1821 |
|
anymore if a disk is non-present. |
| 1822 |
|
20050409 Various minor fixes (a bintrans bug, and some other things). |
| 1823 |
|
The wdc seems to work with Playstation2 emulation, but there |
| 1824 |
|
is a _long_ annoying delay when disks are detected. |
| 1825 |
|
Fixing a really important bintrans bug (when devices and RAM |
| 1826 |
|
are mixed within 4KB pages), which was triggered with |
| 1827 |
|
NetBSD/playstation2 kernels. |
| 1828 |
|
20050410 Adding a dummy dev_ps2_ether (just so that NetBSD doesn't |
| 1829 |
|
complain as much during bootup). |
| 1830 |
|
Symbols starting with '$' are now ignored. |
| 1831 |
|
Renaming dev_ps2_ohci.c to dev_ohci.c, etc. |
| 1832 |
|
20050411 Moving the bintrans-cache-isolation check from cpu_mips.c to |
| 1833 |
|
cpu_mips_coproc.c. (I thought this would give a speedup, but |
| 1834 |
|
it's not noticable.) |
| 1835 |
|
Better playstation2 sbus interrupt code. |
| 1836 |
|
Skip ahead many ticks if the count register is read manually. |
| 1837 |
|
(This increases the speed of delay-loops that simply read |
| 1838 |
|
the count register.) |
| 1839 |
|
20050412 Updates to the playstation2 timer/interrupt code. |
| 1840 |
|
Some other minor updates. |
| 1841 |
|
20050413 NetBSD/cobalt runs from a disk image :-) including userland; |
| 1842 |
|
updating the documentation on how to install NetBSD/cobalt |
| 1843 |
|
using NetBSD/pmax (!). |
| 1844 |
|
Some minor bintrans updates (no real speed improvement) and |
| 1845 |
|
other minor updates (playstation2 now uses the -o options). |
| 1846 |
|
20050414 Adding a dummy x86 (and AMD64) mode. |
| 1847 |
|
20050415 Adding some (32-bit and 16-bit) x86 instructions. |
| 1848 |
|
Adding some initial support for non-SCSI, non-IDE floppy |
| 1849 |
|
images. (The x86 mode can boot from these, more or less.) |
| 1850 |
|
Moving the devices/ and include/ directories to src/devices/ |
| 1851 |
|
and src/include/, respectively. |
| 1852 |
|
20050416 Continuing on the x86 stuff. (Adding pc_bios.c and some simple |
| 1853 |
|
support for software interrupts in 16-bit mode.) |
| 1854 |
|
20050417 Ripping out most of the x86 instruction decoding stuff, trying |
| 1855 |
|
to rewrite it in a cleaner way. |
| 1856 |
|
Disabling some of the least working CPU families in the |
| 1857 |
|
configure script (sparc, x86, alpha, hppa), so that they are |
| 1858 |
|
not enabled by default. |
| 1859 |
|
20050418 Trying to fix the bug which caused problems when turning on |
| 1860 |
|
and off bintrans interactively, by flushing the bintrans cache |
| 1861 |
|
whenever bintrans is manually (re)enabled. |
| 1862 |
|
20050419 Adding the 'lswi' ppc instruction. |
| 1863 |
|
Minor updates to the x86 instruction decoding. |
| 1864 |
|
20050420 Renaming x86 register name indices from R_xx to X86_R_xx (this |
| 1865 |
|
makes building on Tru64 nicer). |
| 1866 |
|
20050422 Adding a check for duplicate MIPS TLB entries on tlbwr/tlbwi. |
| 1867 |
|
20050427 Adding screenshots to guestoses.html. |
| 1868 |
|
Some minor fixes and testing for the next release. |
| 1869 |
|
|
| 1870 |
|
============== RELEASE 0.3.2 ============== |
| 1871 |
|
|
| 1872 |
|
20050428 Disabling the "-fmove-all-movables" option in the configure |
| 1873 |
|
script, because it causes the compile to fail on OpenBSD/sgi. |
| 1874 |
|
20050502 Minor updates. |
| 1875 |
|
20050503 Removing the WRT54G mode (it was bogus anyway), and adding a |
| 1876 |
|
comment about Windows NT for MIPS in doc/experiments.html. |
| 1877 |
|
Minor updates to the x86 instruction decoding. |
| 1878 |
|
20050504 Adding some more x86 instructions. |
| 1879 |
|
Adding support for reading files from ISO9660 CDROMs (including |
| 1880 |
|
gzipped files). It's an ugly hack, but it seems to work. |
| 1881 |
|
Various other minor updates (dev_vga.c, pc_bios.c etc). |
| 1882 |
|
20050505 Some more x86-related updates. |
| 1883 |
|
Beginning (what I hope will be) a major code cleanup phase. |
| 1884 |
|
"bootris" (an x86 bootsector) runs :-) |
| 1885 |
|
20050506 Adding some more x86 instructions. |
| 1886 |
|
20050507 tmpnam => mkstemp. |
| 1887 |
|
Working on a hack to allow VGA charcells to be shown even when |
| 1888 |
|
not running with X11. |
| 1889 |
|
Adding more x86 instructions. |
| 1890 |
|
20050508 x86 32-bit SIB addressing fix, and more instructions. |
| 1891 |
|
20050509 Adding more x86 instructions. |
| 1892 |
|
20050510 Minor documentation updates, and other updates (x86 stuff etc.) |
| 1893 |
|
20050511 More x86-related updates. |
| 1894 |
|
20050513 Various updates, mostly x86-related. (Trying to fix flag |
| 1895 |
|
calculation, factoring out the ugly shift/rotate code, and |
| 1896 |
|
some other things.) |
| 1897 |
|
20050514 Adding support for loading some old i386 a.out executables. |
| 1898 |
|
Finally beginning the cleanup of machine/PROM/bios dependant |
| 1899 |
|
info. |
| 1900 |
|
Some minor documentation updates. |
| 1901 |
|
Trying to clean up ARCBIOS stuff a little. |
| 1902 |
|
20050515 Trying to make it possible to actually use more than one disk |
| 1903 |
|
type per machine (floppy, ide, scsi). |
| 1904 |
|
Trying to clean up the kbd vs PROM console stuff. (For PC and |
| 1905 |
|
ARC emulation modes, mostly.) |
| 1906 |
|
Beginning to add an 8259 interrupt controller, and connecting |
| 1907 |
|
it to the x86 emulation. |
| 1908 |
|
20050516 The first x86 interrupts seem to work (keyboard stuff). |
| 1909 |
|
Adding a 8253/8254 programmable interval timer skeleton. |
| 1910 |
|
FreeDOS now reaches a command prompt and can be interacted |
| 1911 |
|
with. |
| 1912 |
|
20050517 After some bugfixes, MS-DOS also (sometimes) reaches a |
| 1913 |
|
command prompt now. |
| 1914 |
|
Trying to fix the pckbc to work with MS-DOS' keyb.com, but no |
| 1915 |
|
success yet. |
| 1916 |
|
20050518 Adding a simple 32-bit x86 MMU skeleton. |
| 1917 |
|
20050519 Some more work on the x86 stuff. (Beginning the work on paging, |
| 1918 |
|
and various other fixes). |
| 1919 |
|
20050520 More updates. Working on dev_vga (4-bit graphics modes), adding |
| 1920 |
|
40 columns support to the PC bios emulation. |
| 1921 |
|
Trying to add support for resizing windows when switching |
| 1922 |
|
between graphics modes. |
| 1923 |
|
20050521 Many more x86-related updates. |
| 1924 |
|
20050522 Correcting the initial stack pointer's sign-extension for |
| 1925 |
|
ARCBIOS emulation (thanks to Alec Voropay for noticing the |
| 1926 |
|
error). |
| 1927 |
|
Continuing on the cleanup (ARCBIOS etc). |
| 1928 |
|
dev_vga updates. |
| 1929 |
|
20050523 More x86 updates: trying to add some support for protected mode |
| 1930 |
|
interrupts (via gate descriptors) and many other fixes. |
| 1931 |
|
More ARCBIOS cleanup. |
| 1932 |
|
Adding a device flag which indicates that reads cause no |
| 1933 |
|
side-effects. (Useful for the "dump" command in the debugger, |
| 1934 |
|
and other things.) |
| 1935 |
|
Adding support for directly starting up x86 ELFs, skipping the |
| 1936 |
|
bootloader stage. (Most ELFs, however, are not suitable for |
| 1937 |
|
this.) |
| 1938 |
|
20050524 Adding simple 32-bit x86 TSS task switching, but no privilege |
| 1939 |
|
level support yet. |
| 1940 |
|
More work on dev_vga. A small "Copper bars" demo works. :-) |
| 1941 |
|
Adding support for Trap Flag (single-step exceptions), at least |
| 1942 |
|
in real mode, and various other x86-related fixes. |
| 1943 |
|
20050525 Adding a new disk image prefix (gH;S;) which can be used to |
| 1944 |
|
override the default nr of heads and sectors per track. |
| 1945 |
|
20050527 Various bug fixes, more work on the x86 mode (stack change on |
| 1946 |
|
interrupts between different priv.levels), and some minor |
| 1947 |
|
documentation updates. |
| 1948 |
|
20050528 Various fixes (x86 stuff). |
| 1949 |
|
20050529 More x86 fixes. An OpenBSD/i386 bootfloppy reaches userland |
| 1950 |
|
and can be interacted with (although there are problems with |
| 1951 |
|
key repetition). NetBSD/i386 triggers a serious CISC-related |
| 1952 |
|
problem: instruction fetches across page boundaries, where |
| 1953 |
|
the later part isn't actually part of the instruction. |
| 1954 |
|
20050530 Various minor updates. (Documentation updates, etc.) |
| 1955 |
|
20050531 Adding some experimental code (experiments/new_test_*) which |
| 1956 |
|
could be useful for dynamic (but not binary) translation in |
| 1957 |
|
the future. |
| 1958 |
|
20050602 Adding a dummy ARM skeleton. |
| 1959 |
|
Fixing the pckbc key repetition problem (by adding release |
| 1960 |
|
scancodes for all keypresses). |
| 1961 |
|
20050603 Minor updates for the next release. |
| 1962 |
|
20050604 Release testing. Minor updates. |
| 1963 |
|
|
| 1964 |
|
============== RELEASE 0.3.3 ============== |
| 1965 |
|
|
| 1966 |
|
20050604 There'll probably be a 0.3.3.1 release soon, with some very |
| 1967 |
|
very tiny updates. |
| 1968 |
|
|
| 1969 |
|
============== RELEASE 0.3.3.1 ============== |
| 1970 |
|
|
| 1971 |
|
20050609 Adding simple MIPS IPIs (to dev_mp). |
| 1972 |
|
20050611 Adding an ugly hack to track down low-reference bugs |
| 1973 |
|
(define TRACE_NULL_CRASHES, or configure --tracenull). |
| 1974 |
|
Other minor updates. |
| 1975 |
|
20050612 Adding a dummy evbmips mode. |
| 1976 |
|
|
| 1977 |
|
============== RELEASE 0.3.3.2 ============== |
| 1978 |
|
|
| 1979 |
|
20050617 Experimenting some more with netbooting OpenBSD/sgi. Adding |
| 1980 |
|
a hack which allows emulated ethernet networks to be |
| 1981 |
|
distributed across multiple emulator processes. |
| 1982 |
|
20050618 Minor updates (documentation, dummy YAMON emulation, etc). |
| 1983 |
|
20050620 strcpy/strcat -> strlcpy/strlcat updates. |
| 1984 |
|
Some more progress on evbmips (Malta). |
| 1985 |
|
20050621 Adding a section to doc/configfiles.html about ethernet |
| 1986 |
|
emulation across multiple hosts. |
| 1987 |
|
Beginning the work on the ARM translation engine (using the |
| 1988 |
|
dynamic-but-not-binary translation method). |
| 1989 |
|
Fixing a bintrans bug: 0x9fc00000 should always be treated as |
| 1990 |
|
PROM area, just as 0xbfc00000 is. |
| 1991 |
|
Minor progress on Malta emulation (the PCI-ISA bus). |
| 1992 |
|
20050622 NetBSD/evbmips can now be installed (using another emulated |
| 1993 |
|
machine) and run (including userland and so on). :-) |
| 1994 |
|
Spliting up the bintrans haddr_entry field into two (one for |
| 1995 |
|
read, one for write). Probably not much of a speed increase, |
| 1996 |
|
though. |
| 1997 |
|
Updating some NetBSD 2.0 -> 2.0.2 in the documentation. |
| 1998 |
|
20050623 Minor updates (documentation, the TODO file, etc). |
| 1999 |
|
gzipped kernels are now always automagically gunzipped when |
| 2000 |
|
loaded. |
| 2001 |
|
20050624 Adding a dummy Playstation Portable (PSP) mode, just barely |
| 2002 |
|
enough to run Hello World (in weird colors :-). |
| 2003 |
|
Removing the -b command line option; old bintrans is enabled |
| 2004 |
|
by default instead. It makes more sense. |
| 2005 |
|
Trying to finally fix the non-working performance measurement |
| 2006 |
|
thing (instr/second etc). |
| 2007 |
|
20050625 Continuing on the essential basics for ARM emulation. Two |
| 2008 |
|
instructions seem to work, a branch and a simple "mov". (The |
| 2009 |
|
mov arguments are not correct yet.) Performance is definitely |
| 2010 |
|
reasonable. |
| 2011 |
|
Various other minor updates. |
| 2012 |
|
Adding the ARM "bl" instruction. |
| 2013 |
|
Adding support for combining multiple ARM instructions into one |
| 2014 |
|
function call. ("mov" + "mov" is the only one implemented so |
| 2015 |
|
far, but it seems to work.) |
| 2016 |
|
Cleaning up some IP32 interrupt things (crime/mace); disabling |
| 2017 |
|
the PS/2 keyboard controller on IP32, so that NetBSD/sgimips |
| 2018 |
|
boots into userland again. |
| 2019 |
|
20050626 Finally! NetBSD/sgimips netboots. Adding instructions to |
| 2020 |
|
doc/guestoses.html on how to set up an nfs server etc. |
| 2021 |
|
Various other minor fixes. |
| 2022 |
|
Playstation Portable ".pbp" files can now be used directly. |
| 2023 |
|
(The ELF part of the .pbp is extracted transparently.) |
| 2024 |
|
Converting some sprintf -> snprintf. |
| 2025 |
|
Adding some more instructions to the ARM disassembler. |
| 2026 |
|
20050627 More ARM updates. Adding some simple ldr(b), str(b), |
| 2027 |
|
cmps, and conditional branch instructions, enough to run |
| 2028 |
|
a simple Hello World program. |
| 2029 |
|
All ARM instructions are now inlined/generated for all possible |
| 2030 |
|
condition codes. |
| 2031 |
|
Adding add and sub, and more load/store instructions. |
| 2032 |
|
Removing dummy files: cpu_alpha.c, cpu_hppa.c, and cpu_sparc.c. |
| 2033 |
|
Some minor documentation updates; preparing for a 0.3.4 |
| 2034 |
|
release. Updating some URLs. |
| 2035 |
|
|
| 2036 |
|
============== RELEASE 0.3.4 ============== |
| 2037 |
|
|
| 2038 |
|
20050628 Continuing the work on the ARM translation engine. end_of_page |
| 2039 |
|
works. Experimenting with load/store translation caches |
| 2040 |
|
(virtual -> physical -> host). |
| 2041 |
|
20050629 More ARM stuff (memory access translation cache, mostly). This |
| 2042 |
|
might break a lot of stuff elsewhere, probably some MIPS- |
| 2043 |
|
related translation things. |
| 2044 |
|
20050630 Many load/stores are now automatically generated and included |
| 2045 |
|
into cpu_arm_instr.c; 1024 functions in total (!). |
| 2046 |
|
Fixes based on feedback from Alec Voropay: only print 8 hex |
| 2047 |
|
digits instead of 16 in some cases when emulating 32-bit |
| 2048 |
|
machines; similar 8 vs 16 digit fix for breakpoint addresses; |
| 2049 |
|
4Kc has 16 TLB entries, not 48; the MIPS config select1 |
| 2050 |
|
register is now printed with "reg ,0". |
| 2051 |
|
Also changing many other occurances of 16 vs 8 digit output. |
| 2052 |
|
Adding cache associativity fields to mips_cpu_types.h; updating |
| 2053 |
|
some other cache fields; making the output of |
| 2054 |
|
mips_cpu_dumpinfo() look nicer. |
| 2055 |
|
Generalizing the bintrans stuff for device accesses to also |
| 2056 |
|
work with the new translation system. (This might also break |
| 2057 |
|
some MIPS things.) |
| 2058 |
|
Adding multi-load/store instructions to the ARM disassembler |
| 2059 |
|
and the translator, and some optimizations of various kinds. |
| 2060 |
|
20050701 Adding a simple dev_disk (it can read/write sectors from |
| 2061 |
|
disk images). |
| 2062 |
|
20050712 Adding dev_ether (a simple ethernet send/receive device). |
| 2063 |
|
Debugger command "ninstrs" for toggling show_nr_of_instructions |
| 2064 |
|
during runtime. |
| 2065 |
|
Removing the framebuffer logo. |
| 2066 |
|
20050713 Continuing on dev_ether. |
| 2067 |
|
Adding a dummy cpu_alpha (again). |
| 2068 |
|
20050714 More work on cpu_alpha. |
| 2069 |
|
20050715 More work on cpu_alpha. Many instructions work, enough to run |
| 2070 |
|
a simple framebuffer fill test (similar to the ARM test). |
| 2071 |
|
20050716 More Alpha stuff. |
| 2072 |
|
20050717 Minor updates (Alpha stuff). |
| 2073 |
|
20050718 Minor updates (Alpha stuff). |
| 2074 |
|
20050719 Generalizing some Alpha instructions. |
| 2075 |
|
20050720 More Alpha-related updates. |
| 2076 |
|
20050721 Continuing on cpu_alpha. Importing rpb.h from NetBSD/alpha. |
| 2077 |
|
20050722 Alpha-related updates: userland stuff (Hello World using |
| 2078 |
|
write() compiled statically for FreeBSD/Alpha runs fine), and |
| 2079 |
|
more instructions are now implemented. |
| 2080 |
|
20050723 Fixing ldq_u and stq_u. |
| 2081 |
|
Adding more instructions (conditional moves, masks, extracts, |
| 2082 |
|
shifts). |
| 2083 |
|
20050724 More FreeBSD/Alpha userland stuff, and adding some more |
| 2084 |
|
instructions (inserts). |
| 2085 |
|
20050725 Continuing on the Alpha stuff. (Adding dummy ldt/stt.) |
| 2086 |
|
Adding a -A command line option to turn off alignment checks |
| 2087 |
|
in some cases (for translated code). |
| 2088 |
|
Trying to remove the old bintrans code which updated the pc |
| 2089 |
|
and nr_of_executed_instructions for every instruction. |
| 2090 |
|
20050726 Making another attempt att removing the pc/nr of instructions |
| 2091 |
|
code. This time it worked, huge performance increase for |
| 2092 |
|
artificial test code, but performance loss for real-world |
| 2093 |
|
code :-( so I'm scrapping that code for now. |
| 2094 |
|
Tiny performance increase on Alpha (by using ret instead of |
| 2095 |
|
jmp, to play nice with the Alpha's branch prediction) for the |
| 2096 |
|
old MIPS bintrans backend. |
| 2097 |
|
20050727 Various minor fixes and cleanups. |
| 2098 |
|
20050728 Switching from a 2-level virtual to host/physical translation |
| 2099 |
|
system for ARM emulation, to a 1-level translation. |
| 2100 |
|
Trying to switch from 2-level to 1-level for the MIPS bintrans |

|
system as well (Alpha only, so far), but there is at least one |
| 2102 |
|
problem: caches and/or how they work with device mappings. |
| 2103 |
|
20050730 Doing the 2-level to 1-level conversion for the i386 backend. |
| 2104 |
|
The cache/device bug is still there for R2K/3K :( |
| 2105 |
|
Various other minor updates (Malta etc). |
| 2106 |
|
The mc146818 clock now updates the UIP bit in a way which works |
| 2107 |
|
better with Linux for at least sgimips and Malta emulation. |
| 2108 |
|
Beginning the work on refactoring the dyntrans system. |
| 2109 |
|
20050731 Continuing the dyntrans refactoring. |
| 2110 |
|
Fixing a small but serious host alignment bug in memory_rw. |
| 2111 |
|
Adding support for big-endian load/stores to the i386 bintrans |
| 2112 |
|
backend. |
| 2113 |
|
Another minor i386 bintrans backend update: stores from the |
| 2114 |
|
zero register are now one (or two) loads shorter. |
| 2115 |
|
The slt and sltu instructions were incorrectly implemented for |
| 2116 |
|
the i386 backend; only using them for 32-bit mode for now. |
| 2117 |
|
20050801 Continuing the dyntrans refactoring. |
| 2118 |
|
Cleanup of the ns16550 serial controller (removing unnecessary |
| 2119 |
|
code). |
| 2120 |
|
Bugfix (memory corruption bug) in dev_gt, and a patch/hack from |
| 2121 |
|
Alec Voropay for Linux/Malta. |
| 2122 |
|
20050802 More cleanup/refactoring of the dyntrans subsystem: adding |
| 2123 |
|
phys_page pointers to the lookup tables, for quick jumps |
| 2124 |
|
between translated pages. |
| 2125 |
|
Better fix for the ns16550 device (but still no real FIFO |
| 2126 |
|
functionality). |
| 2127 |
|
Converting cpu_ppc to the new dyntrans system. This means that |
| 2128 |
|
I will have to start from scratch with implementing each |
| 2129 |
|
instruction, and figure out how to implement dual 64/32-bit |
| 2130 |
|
modes etc. |
| 2131 |
|
Removing the URISC CPU family, because it was useless. |
| 2132 |
|
20050803 When selecting a machine type, the main type can now be omitted |
| 2133 |
|
if the subtype name is unique. (I.e. -E can be omitted.) |
| 2134 |
|
Fixing a dyntrans/device update bug. (Writes to offset 0 of |
| 2135 |
|
a device could sometimes go unnoticed.) |
| 2136 |
|
Adding an experimental "instruction combination" hack for |
| 2137 |
|
ARM for memset-like byte fill loops. |
| 2138 |
|
20050804 Minor progress on cpu_alpha and related things. |
| 2139 |
|
Finally fixing the MIPS dmult/dmultu bugs. |
| 2140 |
|
Fixing some minor TODOs. |
| 2141 |
|
20050805 Generalizing the 8259 PIC. It now also works with Cobalt |
| 2142 |
|
and evbmips emulation, in addition to the x86 hack. |
| 2143 |
|
Finally converting the ns16550 device to use devinit. |
| 2144 |
|
Continuing the work on the dyntrans system. Thinking about |
| 2145 |
|
how to add breakpoints. |
| 2146 |
|
20050806 More dyntrans updates. Breakpoints seem to work now. |
| 2147 |
|
20050807 Minor updates: cpu_alpha and related things; removing |
| 2148 |
|
dev_malta (as it isn't used any more). |
| 2149 |
|
Dyntrans: working on general "show trace tree" support. |
| 2150 |
|
The trace tree stuff now works with both the old MIPS code and |
| 2151 |
|
with newer dyntrans modes. :) |
| 2152 |
|
Continuing on Alpha-related stuff (trying to get *BSD to boot |
| 2153 |
|
a bit further, adding more instructions, etc). |
| 2154 |
|
20050808 Adding a dummy IA64 cpu family, and continuing the refactoring |
| 2155 |
|
of the dyntrans system. |
| 2156 |
|
Removing the regression test stuff, because it was more or |
| 2157 |
|
less useless. |
| 2158 |
|
Adding loadlinked/storeconditional type instructions to the |
| 2159 |
|
Alpha emulation. (Needed for Linux/alpha. Not very well tested |
| 2160 |
|
yet.) |
| 2161 |
|
20050809 The function call trace tree now prints a per-function nr of |
| 2162 |
|
arguments. (Semi-meaningless, since that data isn't read yet |
| 2163 |
|
from the ELFs; some hardcoded symbols such as memcpy() and |
| 2164 |
|
strlen() work fine, though.) |
| 2165 |
|
More dyntrans refactoring; taking out more of the things that |
| 2166 |
|
are common to all cpu families. |
| 2167 |
|
20050810 Working on adding support for "dual mode" for PPC dyntrans |
| 2168 |
|
(i.e. both 64-bit and 32-bit modes). |
| 2169 |
|
(Re)adding some simple PPC instructions. |
| 2170 |
|
20050811 Adding a dummy M68K cpu family. The dyntrans system isn't ready |
| 2171 |
|
for variable-length ISAs yet, so it's completely bogus so far. |
| 2172 |
|
Re-adding more PPC instructions. |
| 2173 |
|
Adding a hack to src/file.c which allows OpenBSD/mac68k a.out |
| 2174 |
|
kernels to be loaded. |
| 2175 |
|
Beginning to add PPC loads/stores. So far they only work in |
| 2176 |
|
32-bit mode. |
| 2177 |
|
20050812 The configure file option "add_remote" now accepts symbolic |
| 2178 |
|
host names, in addition to numeric IPv4 addresses. |
| 2179 |
|
Re-adding more PPC instructions. |
| 2180 |
|
20050814 Continuing to port back more PPC instructions. |
| 2181 |
|
Found and fixed the cache/device write-update bug for 32-bit |
| 2182 |
|
MIPS bintrans. :-) |
| 2183 |
|
Triggered a really weird and annoying bug in Compaq's C |
| 2184 |
|
compiler; ccc sometimes outputs code which loads from an |
| 2185 |
|
address _before_ checking whether the pointer was NULL or not. |
| 2186 |
|
(I'm not sure how to handle this problem.) |
| 2187 |
|
20050815 Removing all of the old x86 instruction execution code; adding |
| 2188 |
|
a new (dummy) dyntrans module for x86. |
| 2189 |
|
Taking the first steps to extend the dyntrans system to support |
| 2190 |
|
variable-length instructions. |
| 2191 |
|
Slowly preparing for the next release. |
| 2192 |
|
20050816 Adding a dummy SPARC cpu module. |
| 2193 |
|
Minor updates (documentation etc) for the release. |
| 2194 |
