From: Christophe Lyon Date: Wed, 22 Apr 2020 13:42:04 +0000 (+0000) Subject: testsuite: [arm] Add arm_softfp_ok and arm_hard_ok effective targets. X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=d414c91510bec4f640de29661062d5672a5684e8;p=gcc.git testsuite: [arm] Add arm_softfp_ok and arm_hard_ok effective targets. For arm-linux-gnueabi* targets, a toolchain cannot support the float-abi opposite to the one it has been configured for: since glibc does not support such multilibs, we end up lacking gnu/stubs-*.h when including stdint.h for instance. This patch introduces two new effective targets to detect whether we can compile tests with -mfloat-abi=softfp or -mfloat-abi=hard. This enables to make such tests unsupported rather than fail. 2020-04-22 Christophe Lyon gcc/testsuite/ * lib/target-supports.exp (arm_softfp_ok): New effective target.
