gcc-3.2.3-ppc-asm-spec.patch

linux下编译交叉工具链的工具源码

Based on gcc-3.4.0/gcc-3.3.3h-ppc-asm-spec.patch

Fixes the following errors when building gcc for ppc7450:

/tmp/ccYph3gd.s: Assembler messages:
/tmp/ccYph3gd.s:3823: Error: Unrecognized opcode: `mfvrsave'
/tmp/ccYph3gd.s:3857: Error: Unrecognized opcode: `stvx'
/tmp/ccYph3gd.s:4026: Error: Unrecognized opcode: `lvx'
/tmp/ccYph3gd.s:4027: Error: Unrecognized opcode: `mtvrsave'
make[2]: *** [libgcc/./unwind-dw2.o] Error 1
make[2]: Leaving directory `/opt/crosstool-0.28-rc35/build/powerpc-7450-linux-gnu/gcc-3.2.3-glibc-2.3.2/build-gcc-core/gcc'
make[1]: *** [stmp-multilib] Error 2
make[1]: Leaving directory `/opt/crosstool-0.28-rc35/build/powerpc-7450-linux-gnu/gcc-3.2.3-glibc-2.3.2/build-gcc-core/gcc'
make: *** [all-gcc] Error 2

Note that the "-mcpu=7450" option must appear on the "gcc" command line in
order for "-maltivec" to be passed to the assembler.  Or, "-maltivec" itself
may be passed to the "gcc" command.
