Several tests override the -mfloat-abi option detected by their effective targets. Make sure it is supported, so that these tests are unsupported rather than failures (the inclusion of arm_neon.h otherwise fails for lack of gnu/stubs-*.h) This avoids failures with bfloat16_simd_2_1.c bfloat16_simd_3_1.c bf16_vldn_1.c bf16_vstn_1.c on arm-linux-gnueabi and pr51968.c bfloat16_simd_1_2.c bfloat16_simd_2_2.c bfloat16_simd_3_2.c on arm-linux-gnueabihf. On arm-eabi with default cpu/fpu/mode and a+rm multilibs, bfloat16_simd_2_1.c, bfloat16_simd_3_1.c, bf16_vstn_1.c and bf16_vldn_1.c become unsupported instead of pass because arm_hard_ok fails with "selected processor lacks an FPU". Since we also override the fpu in dg-additional-options, we'd need another effective target (say arm_hard_neon_ok) that would check -mfloat-abi=hard -mfpu=neon at the same time. But we have already so many arm effective targets, it doesn't seem like a good way forward. 2021-03-19 Christophe Lyon <christophe.lyon@linaro.org> gcc/testsuite/ * gcc.target/arm/bfloat16_simd_1_2.c: Add arm_softfp_ok. * gcc.target/arm/bfloat16_simd_2_2.c: Likewise. * gcc.target/arm/bfloat16_simd_3_2.c: Likewise. * gcc.target/arm/pr51968.c: Likewise. * gcc.target/arm/bfloat16_simd_2_1.c: arm_hard_ok. * gcc.target/arm/bfloat16_simd_3_1.c: Likewise. * gcc.target/arm/simd/bf16_vldn_1.c: Likewise. * gcc.target/arm/simd/bf16_vstn_1.c: Likewise. |

This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the files whose names start with COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs/ for how to report bugs usefully. Copyright years on GCC source files may be listed using range notation, e.g., 1987-2012, indicating that every year in the range, inclusive, is a copyrightable year that could otherwise be listed individually.
