------- Comment #113 from lucier at math dot purdue dot edu 2010-03-27 04:27 ------- Created an attachment (id=20220) --> (http://gcc.gnu.org/bugzilla/attachment.cgi?id=20220&action=view) time/mem report compiling compiler.i
This is the time and detailed memory report for 20100302 compiling compiler.i above with main optimization options -O1 -fschedule-insns2 (precise command line and configuration options are given at the top of the file). With these optimization levels cpu time and memory don't look too bad to me. The main routines are parser : 320.93 (59%) usr 1.40 (27%) sys 322.62 (59%) wall 103143 kB (15%) ggc tree CFG cleanup : 73.43 (14%) usr 0.01 ( 0%) sys 73.46 (13%) wall 1388 kB ( 0%) ggc Nothing else is above 3%. I'm building today's gcc on an X86-64 RHEL5 machine with more memory to test with -O3 -fschedule-insns, as this set of options now gives about 20% speedup on some of my codes of this type. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=26854
