//After failing to compile llvm-gcc for MIPS, i decided to cross-compile gcc-4.24 which llvm-gcc is based on and then hack crossdev and toolchain eclass to compile llvm-gcc But crossdev --g 4.2.3 --without-headers mips-pc-linux-gnu crossdev --g 4.2.4 --without-headers mips-pc-linux-gnu both fail sayin undefined reference to `TARGET_R10K_SPECEX' when compilin gcc-stage1 I enclose the 2 files which crossdev suggests
Created attachment 171704 [details] the 2 files made by crossdev/emerge
Caused by patches 92 and 93 from the gcc-4.2.4 gentoo patch archive.

Created attachment 172065 [details] ebuild which fixes the problem Zapping the two sick patches and forcing earlier binutils (to walk-around bug no. 229173) solved the problem crossdev --g 4.2.4-r1 --b 2.18-r1 --without-headers mips-pc-linux-gnu crossdev was successful, the new compiler produces executables for mips{1,2,3} i enclose the hacked ebuild gcc-4.2.4-r1.ebuild (it is only few lines longer than original gcc-4.2.4-r1.ebuild) i leave the bug status unchanged
use gcc-4.3.3
Is this still a problem with gcc-4.3?
Created attachment 313997 [details] sys-devel/gcc-4.2.4-r01.4 build log from Gentoo Prefix This failure occurs on Gentoo Prefix. Currently, the Gentoo Prefix bootstrap process requires GCC 4.2.x due to dependencies added in later versions. I would like to add a MIPS profile to Getnoo Prefix, so this needs to be fixed. This issue occurs consistently on gcc42.fsffrance.org
91_all_mips-ip28_cache_barriers-v4.patch has been dropped from 4.3+. assuming this is fixed as a result.
