Help getting amd64 assembly patch into wine?
by Dan Kegel 04 Oct '12

04 Oct '12

As you might know from watching too many of my patches scroll by, I've been working on adding support for OpenMP to wine. (A handful of games, and a lot of serious apps, seem to use that api.) After getting it nicely organized and cleaned up to the point where it passed all the tests I could throw at it, I submitted it as http://source.winehq.org/patches/data/90524, Alexandre rejected the patch, saying it had multiple problems, but declining to provide any further hints. He suggested I find someone to work with to get it in... so here I am, hat in hand, asking for help. The patch adds support for OpenMP programs like this: // Compile with "cl test.c /openmp" #include <omp.h> #include <stdio.h> int main (int argc, char **argv) { #pragma omp parallel { printf("%d\n", omp_get_thread_num()); } } Later patches add support for other OpenMP constructs. My patch doesn't actually parallelize the app, but it does let it run rather than crash on unimplemented _vcomp_fork. Visual C will happily provide an assembly listing of this program showing how _vcomp_fork is called, so understanding that interface well enough to pass simple tests wasn't hard. The main challenge was figuring out how to get the variable list of arguments off the stack, and then put them back onto the stack when calling the provided function pointer. This bit of varargs hackery can't be done in pure C as far as I can tell, so I used assembly. I started programming in machine language long ago, so getting that working wasn't too hard once I realized that's what was needed. Getting it to pass the Alexandre test is another matter. Alexandre did give feedback on one earlier iteration of the patch, telling me I was re-inventing the wheel, so I tossed my old assembly and copied the helper-calling code nearly verbatim from call_method in oleaut32/typelib.c. Maybe he objects to not passing copies of the arguments in the floating point registers on amd64... but the arguments are always pointers, so that shouldn't be needed. I'm definitely not yet comfortable with the ASM_CFI stuff, so perhaps there's a problem there, but I did at least verify that injecting a fault into _test_vcomp_fork_worker5() still yielded a good stack trace on both x86 and amd64 in winedbg. There aren't many comments, and the ones I did add aren't the greatest, but I doubt that's the issue. Perhaps he objects to breaking up _vcomp_fork into three functions, but I couldn't see any other way to write it without making later patches like http://source.winehq.org/patches/data/90527 (and a future patch that adds actual multiple threads) put more logic than seems wise into assembly. So maybe it's none of the above. If someone can suggest what I might be missing, I'd appreciate it. Even just "It will break if..." or "Better compare how this was done in..." would be very helpful. Thanks!

Hi, While running your changed tests on Windows, I think I found new failures. Being a bot and all I'm not very good at pattern recognition, so I might be wrong, but could you please double-check?

Besides many not trivial kernel drivers (if not all) really dig into internal kernel structures. Same for KeGetCurrentThread. -- Dmitry.
