I am tryng to compile clean mainline kernel with a few different config files
and running into errors with some configs.
I am building on RHEL6.3 with following binaries:
gcc (GCC) 4.4.6 20120305 (Red Hat 4.4.6-4)
GNU ld version 2.20.51.0.2-5.34.el6 20100205
binutils-2.20.51.0.2-5.34.el6.ppc64
binutils-devel-2.20.51.0.2-5.34.el6.ppc64
I am getting the error with several files and configs, but other configs
(eg: ppc64_defconfig, pmac32_defconfig) build fine.
For instance, with latest mainline kernel (commit 6c2580c) and ppc64_defconfig,
I get:
make O=linux-obj mrproper
make O=linux-obj ppc64e_defconfig
make O=linux-obj arch/powerpc/platforms/85xx/smp.o
...
CC arch/powerpc/platforms/85xx/smp.o
{standard input}: Assembler messages:

make[2]: *** [arch/powerpc/platforms/85xx/smp.o] Error 1
make[1]: *** [arch/powerpc/platforms/85xx/smp.o] Error 2
Not sure if 240 is a line number in smp.c, but looking through the function
containing line 240, I was able to compile the smp.c after commenting out
the two WARN_ON() messages.

The pre-processor output for the first WARN_ON() is:
---
({ int __ret_warn_on = !!(nr < 0 || nr >= 32); if
(__builtin_constant_p(__ret_warn_on)) { if (__ret_warn_on) do { __asm__

__builtin_expect(!!(__ret_warn_on), 0); });

Should I be doing something different to build with these configs ?
