FWIW, attached is a similar patch that adds a -falways-use-llvm-vaarg flag to Clang. Applies against mainline. (As discussed, va_arg isn't really supported well so this probably doesn't work well on anything other than simple code, YMMV, etc) ~Will On Thu, May 12, 2011 at 12:29 PM, Arushi Aggarwal <arushi987 at gmail.com> wrote: >...

...o manually lowering it in the frontend, same as the llvm-gcc patch sent earlier does. ~Will On Wed, Aug 17, 2011 at 2:41 PM, Eric Christopher <echristo at apple.com> wrote: > > On Aug 17, 2011, at 11:53 AM, Will Dietz wrote: > >> FWIW, attached is a similar patch that adds a -falways-use-llvm-vaarg >> flag to Clang. >> >> Applies against mainline. >> >> (As discussed, va_arg isn't really supported well so this probably >> doesn't work well on anything other than simple code, YMMV, etc) >> >> ~Will >> >> On Thu,...

Sergey, Here's a patch on llvm-gcc which adds a flag "-fuse-llvm-va-arg". (Note that this patch won't ever be part of llvm-gcc upstream. It will most likely be deprecated by later changes.) - pdox -------------- next part -------------- An HTML attachment was scrubbed...
