Hi The attached patch fixes some tests which fail when testing gcc for a arm-none-linux-gnueabihf target because they do not expect to be built with a hard float ABI.
The change in target-supports.exp fixes arm-fp16-ops-5.c and arm-fp16-ops-6.c. Tested on arm-none-linux-gnueabihf using qemu-arm, and does not cause any other tests to break. Comments? This is my first patch, so please point out anything wrong. 2013-08-15 Charles Baylis <charles.bay...@linaro.org> * gcc.dg/builtin-apply2.c: skip test on arm hardfloat ABI targets * gcc.dg/tls/pr42894.c: Use -mfloat-abi=soft as Thumb1 does not support hardfloat ABI * arm/thumb-ltu.c: Use -mfloat-abi=soft as Thumb1 does not support hardfloat ABI * target-supports.exp: don't force -mfloat-abi=soft when building for hardfloat target
