Hello there. I was exploring about peephole and peephole2 optimisation passes of gcc c compiler. when compiling a test.c programme like this - ~$ gcc test.c -fpeephole2 -da there was no dump for peephole2 pass. same is for -fpeephole. Does it mean that peephole passes are not done or is there any other way to do so. Please help me Best Regards vikramsp -- View this message in context: http://old.nabble.com/gcc-peephole-problem-tp31339261p31339261.html Sent from the gcc - Help mailing list archive at Nabble.com.
