Howdy,
I recently tried compiling Wine with tcc, which found a few bugs. I've
filed some on Savannah (and have before as well), but that didn't
garner much attention, so I'm writing here as well. If that's
unwelcome, please let me know and I'll refrain :).
Now then, I used wine-1.5.12 (recent development snapshot), and tinycc
from git (commit 56e23984b9cd3b58e1766748524e63f8301ccd68). Compared
to 0.9.25, it gets much further, a couple of my bugs were fixed
already:
https://savannah.nongnu.org/bugs/?33010 - configure misses most dependencies
https://savannah.nongnu.org/bugs/?33713 - tinycc doesn't support u_int64_t
the new bugs:
https://savannah.nongnu.org/bugs/?37240 - tinycc: unknown opcode 'movq'
https://savannah.nongnu.org/bugs/?37241 - tinycc: 'error: bad
expression syntax [.]' on some wine files
https://savannah.nongnu.org/bugs/?37242 - tinycc: tmarshal.h:761:
error: identifier expected (wine)
https://savannah.nongnu.org/bugs/?37243 - tinycc: fails to compile
wine's dlls/d3d8/tests/stateblock.c file
https://savannah.nongnu.org/bugs/?37244 - tinycc: lacks -nostartfiles
-nodefaultlibs support, needed by Wine
there are a couple other issues, that I haven't filed bugs for:
A) running ./configure fails to detect libhal and opengl. This can be
worked around by doing:
CC="tcc -L/usr/lib" ./configure
B) TinyCC doesn't seem to support DECLSPEC_HIDDEN / DECLSPEC_HOTPATCH.
C) There are some other areas that fail to compile, though those
appear to be Wine bugs. I've attached a (very hacky) patch that
(mostly) allows wine to compile. For the files mentioned above that
don't compile, make CC=gcc was used to work around it.
After that, wine segfaults on launch, so there's obviously more work
to be done, but these issues make narrowing down that problem harder.
I'd be happy to test any tcc patches, if needed. I've attached
testcases for some of the bugs, when possible. I attempted to use
delta (http://delta.tigris.org/) to narrow down the problems more, but
it seems tinycc doesn't support dumping the preprocessed code?
