[Bug target/44129] Building linux kernel with gcc-4.5.0 and CONFIG_CC_OPTIMIZE_FOR_SIZE segfaults

--- Comment #17 from bdubbs at linuxfromscratch dot org 2010-06-19 00:05 --- I can confirm that changing inline to __always_inline in arch/x86/include/asm/system.h fixed the panic for me. I'm not sure if this fix is the result of an error in the kernel or gcc. Leaving the bug open

--- Comment #11 from bdubbs at linuxfromscratch dot org 2010-05-24 06:32 --- Updated to gcc (GCC) 4.5.1 20100524 (prerelease) but still have the problem. There is something about -Os that triggers the kernel panic in arch/x86/kernel/tsc.c I tried to disable all -O2 options after -Os

--- Comment #9 from bdubbs at linuxfromscratch dot org 2010-05-16 06:38 --- I have traced the problem file for this bug to the kernel file arch/x86/kernel/tsc.c I have two source trees for the 2.6.33.4 kernel, one compiled with gcc-4.4.1 which works and gcc version 4.5.1 20100514

--- Comment #5 from bdubbs at linuxfromscratch dot org 2010-05-14 22:50 --- (In reply to comment #4) I saw you have tried revision 159398. I guess you need to find which file is miscompiled. I have no idea how to do that for the kernel. BTW, you aren't using gold, are you? I

--- Comment #7 from bdubbs at linuxfromscratch dot org 2010-05-15 04:06 --- (In reply to comment #6) You build 2 kernel trees, one with gcc 4.5.1 and one with gcc 4.4.4. You copy binaries from one tree to another and rebuild kernel one file at a time until you find the single file
