Make the order in which we try -mfloat-abi options consistent with the other similar effective targets: try softfp first, then hard. This shows that a few tests implicitly rely on -mfloat-abi=hard, so we add this option via dg-additional-options so that it comes after any potential -mfloat-abi option that the preceding effective-targets might have added. armv8_1m-fpXX-move-1.c tests don't need arm_hard_ok because they don't include arm_mve.h: adding -mfloat-abi=hard when using a soft/softfp toolchain does not lead to the missing include gnu/stubs-*.h error. This patch makes armv8_1m-fpXX-move-1.c pass on arm-linux-gnueabi, and the other tests become unsupported (instead of fail) on this target. On arm-eabi with default cpu/fpu/mode and a+rm multilibs, the same mve/intrinsics/* tests become unsupported instead of pass because arm_hard_ok fails with "selected processor lacks an FPU". Since we also override the fpu via dg-options, we'd need another effective target (say arm_hard_mve_ok) that would check -mfloat-abi=hard -mfpu=auto -march=armv8.1-m.main+mve.fp 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/ * lib/target-supports.exp (check_effective_target_arm_v8_1m_mve_fp_ok_nocache): Fix -mfloat-abi= options order. (check_effective_target_arm_v8_1m_mve_ok_nocache): Likewise * gcc.target/arm/mve/intrinsics/mve_vector_float2.c: Add arm_hard_ok effective target and -mfloat-abi=hard additional option. * gcc.target/arm/mve/intrinsics/mve_vector_int.c: Likewise. * gcc.target/arm/mve/intrinsics/mve_vector_uint.c: Likewise. * gcc.target/arm/mve/intrinsics/mve_vector_uint1.c: Likewise. * gcc.target/arm/mve/intrinsics/mve_vector_uint2.c: Likewise. * gcc.target/arm/mve/intrinsics/vgetq_lane_s64.c: Likewise. * gcc.target/arm/mve/intrinsics/vgetq_lane_u64.c: Likewise. * gcc.target/arm/mve/intrinsics/vsetq_lane_s64.c: Likewise. * gcc.target/arm/mve/intrinsics/vsetq_lane_u64.c: Likewise. * gcc.target/arm/armv8_1m-fp16-move-1.c: Add -mfloat-abi=hard additional option. * gcc.target/arm/armv8_1m-fp32-move-1.c: Likewise. * gcc.target/arm/armv8_1m-fp64-move-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.
