--- Comment #1 from Martin Reinecke <mar...@mpa-garching.mpg.de> 2011-01-05 14:42:20 UTC --- Created attachment 22904 --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=22904 shorter test case More compact test case; the hot spot is marked with "CRITICAL LOOP". Compile with "gcc -O2 -fomit-frame-pointer testcase2.c -lm" and test using "time ./a.out".
