Subject: Re: [PATCH GCC]Catch more MEM_REFs sharing common
addressing part in gimple strength reduction
The new test gcc.dg/tree-ssa/slsr-39.c fails in 64 bit mode (see
http://gcc.gnu.org/ml/gcc-regression/2013-09/msg00455.html ).
Looking for MEM in the dump returns
_12 = MEM[(int[50] *)_17];
MEM[(int[50] *)_20] = _13;
Thanks for reporting, I think this can be fixed by patch:
http://gcc.gnu.org/ml/gcc-patches/2013-09/msg00761.html
Just a quick update on the patch. The proposed patch didn't pass the
x86_64 bootstrap, and I'm working on a better fix.
Thanks,
Yufeng
