Thanks. This is the list of affected targets extracted from the link JBG pointed to: http://toolchain.lug-owl.de/buildbot/?limit=1500 "alpha-linux,bfin-elf,cr16-elf,epiphany-elf,frv-linux,h8300-elf,hppa-linux,m32c-elf,m68k-linux,mep-elf,microblaze-linux,mips64el-linux,mips64-linux,mipsel-linux,mips-linux,mmix,nios2-elf,powerpc64le-linux,powerpc64-linux,powerpcle-linux,powerpc-linux,ppc64-linux,ppc-linux,rl78-elf,rs6000-ibm-aix4.3,s390-linux,s390x-linux,sparc64-linux,sparc-linux,spu,spu-elf,vax-linux,xtensa-linux" Status: With the patch below, x86_64, i386 and powerpc native bootstrap is fine. x86_64 has one test regression in gfortran.dg/lto/pr45586 which I am looking into. Also, mips and mips-64 cross-compiler builds fine. I can check cross-compile builds on all the affected targets listed above. If this all works, I suggest using this patch to put out the current fires and proceed with individual changes to each target later. Also, there are some test case failures when built in non-sse configs in i386. I can get to it after unbreaking this. Is this reasonable?
