--- Comment #2 from Erick Ochoa <erick.oc...@theobroma-systems.com> --- (In reply to Andrew Pinski from comment #1) > Did you try -fno-strict-aliasing? CXX = $(CXX_PATH) -ggdb TUNE_FAST = -mtune=emag -O3 CXXOPTIMIZE = $(TUNE_FAST) -fno-strict-aliasing PASS1_CFLAGS = -flto -fcommon PASS1_CXXFLAGS = -flto -fcommon PASS1_FFLAGS = -flto -fcommon PASS1_LDFLAGS = -flto -fcommon -fno-strict-aliasing I originally did not. I added it as you suggested. I added it to both the compiler and the linker just in case.
