------- Comment #7 from ami_stuff at o2 dot pl 2009-08-17 19:25 ------- The problem is not with "-funswitch-loops" optimization.
I get no ICE with these options (-O2 -fipa-cp-clone -finline-functions -fgcse-after-reload -ftree-vectorize -fpredictive-commoning): OPTFLAGS= -mnobitfield -m68060 -std=c99 -Wdeclaration-after-statement -Wdisabled-optimization -fno-math-errno -D_ISOC99_SOURCE -D_POSIX_C_SOURCE=200112 -D_FILE_OFFSET_BITS=64 -D_LARGEFILE_SOURCE -fno-common -fomit-frame-pointer -Wall -Wno-switch -Wpointer-arith -Wredundant-decls -Wcast-qual -Wwrite-strings -Wundef -O2 -fipa-cp-clone -finline-functions -fgcse-after-reload -ftree-vectorize -fpredictive-commoning I get ICE with -O3: OPTFLAGS= -mnobitfield -m68060 -std=c99 -Wdeclaration-after-statement -Wdisabled-optimization -fno-math-errno -D_ISOC99_SOURCE -D_POSIX_C_SOURCE=200112 -D_FILE_OFFSET_BITS=64 -D_LARGEFILE_SOURCE -fno-common -fomit-frame-pointer -Wall -Wno-switch -Wpointer-arith -Wredundant-decls -Wcast-qual -Wwrite-strings -Wundef -O3 Also, ICE happens ONLY with -m68060 flag! When I use "-m68020 -m6881" or -m68040 there is no ICE! -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=40414
