Add -fmem-report-wpa
For parallel LTO builds setting -fmem-report does not work very well because all the LTRANS phases dump it in parallel and typically interleave it to unreadability. Since usually the memory bottleneck is WPA add a flag to only dump the memory report for that. gcc/: 2012-09-08 Andi Kleen <ak@linux.intel.com> * gcc/common.opt (-fmem-report-wpa): Add * gcc/doc/invoke.texi (-fmem-report-wpa): Document. * gcc/lto/lto.c (do_whole_program_analysis): Run mem_report when mem_report_wpa is set. git-svn-id: https://gcc.gnu.org/svn/gcc/trunk@191095 138bc75d-0d04-0410-961f-82ee72b054a4
