That will let us build fp-test using a cross-compiler. My initial thinking was that since we'd end up testing on a real host (with "-t host" mode), cross-compiling wouldn't be necessary since we could just compile natively on said host. But since we seem to be moving towards supporting cross-compilers, it takes little effort to cross-compile fp-test as well. The main hurdle is to remove the glib dependence as you pointed out. I just wrote a few patches to do this: $ git log --oneline -5 --reverse 48e802b osdep: disable glib-compat.h include with QEMU_NO_GLIB d3c78c7 softfloat: do not include glib headers 744a9c4 tests/tcg/Makefile: define _GNU_SOURCE 661c0e2 tests/fp: fixup e057d45 tests/tcg/Makefile: fp-test build fixup The main difference with your attached patch is that we remove ifdef's from fp-test.c while keeping the osdep.h include. You can fetch the patches from https://github.com/cota/qemu/tree/softfloat-fixes-for-2.12-v1 [BTW the name of the branch is just to keep your original branch name; I'm in now way intending for this to be part of 2.12 :>] Thanks, Emilio
