In running the spec 2006 testsuite with several options, we discovered that -mtune=power8 (which turns on the -mpower8-fusion option) has a segmentation fault in two benchmarks: 403.gcc when built with -O2 -mcpu=power7 -mtune=power8 -m32 435.gromacs when built with -O3 -funroll-loops -mcpu=power7 -mtune=power8 -m32 In the gcc case, I tracked it down to the fusion op in the function strength_reduce in the file loop.c. It was wanting to use the result of the addis instruction after the loop. It wanted to optimize: lis 10,loop_dump_stream@ha lwz 6,loop_dump_stream@l(6) stw 10,24(1) to: lis 6,loop_dump_stream@ha lwz 6,loop_dump_stream@l(6) stw 10,24(1) The problem is fusion was implemented using define_peephole, and the register live notes are not correct when peepholes are done.
In looking at the code for 403.gcc, the compiler spills the addis value to the stack and then reloads it later. It would be more optimal to just redo the addis value.
Created attachment 30659 [details] Proposed patch to fix problem
I forgot to mention, with this patch, I have built and successfully run 403.gcc and 435.gromacs using the -O2 -m32 -mcpu=power7 -mtune=power8 options that broke 403.gcc, and also with the -O3 -funroll-loops -m32 -mcpu=power7 -mtune=power8 that broke 435.gromacs.
Fixed in subversion id 201792.
