Hi,
When I'm trying to compile kernel from just cvsup'ed sources on system
builded/installed last evening I have following error message. This problem
could be solved by lowering optimisation to -O, but previously I have no
problems with -O2 for kernels.
cc -c -O2 -march=pentium -Wall -Wredundant-decls -Wnested-externs
-Wstrict-proto
types -Wmissing-prototypes -Wpointer-arith -Winline -Wcast-qual

/tmp/ccfL2694.s: Assembler messages:

Following is the assembler code in question:
.L659:
movl %ecx,%eax
jmp .L658
.p2align 2,0x90
.L643:
testb $1,%bl
je .L644
#APP
movl %dr0,-16(%ebp) <-------Line 3563 is here
#NO_APP

movl %dr1,%edx
#NO_APP
leal -16(%ebp),%eax
