* Userland (syscall) emulation. |
31 |
* |
32 |
* TODO: |
33 |
* |
34 |
* environment passing for most emulation modes |
35 |
* |
36 |
* implement more syscalls |
37 |
* |
38 |
* 32-bit vs 64-bit problems? MIPS n32, o32, n64? |
39 |
* |
40 |
* Dynamic ELFs? |
41 |
* |
42 |
* Try to prefix "/emul/mips/" or similar to all filenames, |
43 |
* and only if that fails, try the given filename. |
44 |
* Read this setting from an environment variable, and only |
45 |
* if there is none, fall back to hardcoded string. |
46 |
* |
47 |
* Automagic errno translation! |
48 |
* |
49 |
* Memory allocation? mmap, munmap, mprotect, etc. |
50 |
* mprotect = unmap in dyntrans... |
51 |
* |
52 |
* File descriptor (0,1,2) assumptions? Find and fix these? |
53 |
* |
54 |
* |
55 |
* This module needs more cleanup. |
56 |
* ------------------------------- |
57 |
* |
58 |
* |
59 |
* NOTE: This module (useremul.c) is just a quick hack so far, to see if |
60 |
* userland emulation works at all. It only works for Hello World- |
61 |
* style programs compiled for FreeBSD/alpha or NetBSD/mips. |
