Re: race condition in indirect call value profiling?

Thanks for re-raising this issue. I'm certainly interested in applying the patch. I figured I had missed the boat for GCC 4.5 and was going to re-re-raise the issue for 4.6. I someone approves the patch, I'll apply it once we re-enter Stage 1. Cheers, Neil On Fri, Mar 26, 2010 at 10:57 AM, Jac

There are two calls of gen_rtx_VAR_LOCATION in cfgexpand.c. Both calls cast a tree to rtx as the third argument. Why a tree is used in RTL expression? Will it be transformed into RTL later or all RTL passes should recognize it's a tree and just ignore it? Thanks. -- Jie Zhang CodeSourcery (65
