20070616 Implementing the MIPS32/64 revision 2 "ror" instruction.
20070617 Adding a struct for each physpage which keeps track of which
ranges within that page (base offset, length) that are
continuously translatable. When running with native code
generation enabled (-b), a range is added after each read-
ahead loop.
Experimenting with using the physical program counter sample
data (implemented 20070608) together with the "translatable
range" information, to figure out which physical address ranges
would be worth translating to native code (if the number of
samples falling within a range is above a certain threshold).
20070618 Adding automagic building of .index comment files for
src/file/, src/promemul/, src src/useremul/ as well.
Adding a "has been translated" bit to the ranges, so that only
not-yet-translated ranges will be sampled.
20070619 Moving src/cpu.c and src/memory_rw.c into src/cpus/,
src/device.c into src/devices/, and src/machine.c into
src/machines/.
Creating a skeleton cc/ld native backend module; beginning on
the function which will detect cc command line, etc.
20070620 Continuing on the native code generation infrastructure.
20070621 Moving src/x11.c and src/console.c into a new src/console/
subdir (for everything that is console or framebuffer related).
Moving src/symbol*.c into a new src/symbol/, which should
contain anything that is symbol handling related.
20070624 Making the program counter sampling threshold a "settings
variable" (sampling_threshold), i.e. it can now be changed
during runtime.
Switching the RELEASE notes format from plain text to HTML.
If the TMPDIR environment variable is set, it is used instead
of "/tmp" for temporary files.
Continuing on the cc/ld backend: simple .c code is generated,
the compiler and linker are called, etc.
Adding detection of host architecture to the configure script
(again), and adding icache invalidation support (only
implemented for Alpha hosts so far).
20070625 Simplifying the program counter sampling mechanism.
20070626 Removing the cc/ld native code generation stuff, program
counter sampling, etc; it would not have worked well in the
general case.
20070627 Removing everything related to native code generation.
20070629 Removing the (practically unusable) support for multiple
emulations. (The single emulation allowed now still supports
multiple simultaneous machines, as before.)
Beginning on PCCTWO and M88K interrupts.
20070723 Adding a dummy skeleton for emulation of M32R processors.
20070901 Fixing a warning found by "gcc version 4.3.0 20070817
(experimental)" on amd64.
20070905 Removing some more traces of the old "multiple emulations"
code.
Also looking in /usr/local/include and /usr/local/lib for
X11 libs, when running configure.
20070909 Minor updates to the guest OS install instructions, in
preparation for the NetBSD 4.0 release.
20070918 More testing of NetBSD 4.0 RC1.
