BTW, here's the state of toolchains, by architecture:
alpha alpha-linux works arm arm-linux works arm26 support is gone in gcc4, tree is not well either cris cris-linux broken [*3][*4], but gets through arch/cris, so there's some use for it... frv frv-linux 4.1 mostly works [*2], but "U" constraint support is still missing in mainline h8300 h8300-elf broken [*5][*3] i386 x86_64-linux works ia64 ia64-linux works m32r m32r-linux works [*2] m68k m68k-linux works [*2] mips mips64-linux works mips64 mips64-linux works [*1] parisc hppa-linux works [*4]; gcc-4.1 gives an ICE [*7] parisc64 hppa64-linux Linus' tree is broken; gcc builds, but doesn't get far in kernel build; might die later. powerpc powerpc64-linux works ppc powerpc64-linux works s390 s390x-linux works sh sh-linux works [*4] sh64 sh64-linux broken [*6] sparc sparc64-linux works sparc64 sparc64-linux works um toolchain of corresponding sub-arch v850 v850e-linux works [*2][*5] x86_64 x86_64-linux works xtensa, m68knommu: have not tried lately
[*1] except that we get bogus flags passed to as(1) if we are building for 64bit cpu without CONFIG_BUILD_ELF64. [*2] 64bit bugs in binutils, fixes exist [*3] ICE during kernel build [*4] needs a patch to get rid of dependency on target libc headers; fix exists [*5] 64bit bugs in gcc, fixes exist [*6] ICE during libgcc build [*7] 4.0 works, 4.1 gives an ICE when you build on 64bit host with -Os; trimmed-down reproducer is void foo(int sig, int *p) { if (!((1ULL << ((sig)-1)) & 0x300000edcULL)) *p = 0; }
