Description Armin Mohring 2006-06-13 23:45:00 UTC

gentoo-sources 2.6.16-r9
path /usr/src/linux/arch/x86_64.
Makefile contains the following line:
# prevent gcc from generating any FP code by mistake
CFLAGS += $(call cc-option,-mno-sse -mno-mmx -mno-sse2 -mno-3dnow,)

should be 
# prevent gcc from generating any FP code by mistake
# CFLAGS += $(call cc-option,-mno-sse -mno-mmx -mno-sse2 -mno-3dnow,)

Read the comment above the CFLAGS line.

_No_ floating point operations in-kernel, this includes any floating point
operations that are cuased by optimisation to SIMD code by the compiler.

Next time, please grok the thing first, before you dub it a bug.
