commit r16-7154-g31875b910c70dd1e65d4da67562ac02b9b108c68 Author: Artemiy Volkov <[email protected]> Date: Thu Jan 8 11:51:06 2026 +0000 testsuite: require arm_v8_3a_fp16_complex_neon for complex fp16 tests Changes to target-supports.exp from r16-6519-g56dd47c073cabf introduced some new failures for complex fp16 tests with some arm-eabi targets configured with -mfpu=auto. This patch fixes those by (a) requiring the full arm_v8_3a_fp16_complex_neon_ok target instead of just float16 in vect/complex fp16 tests, and (b) simplifying down to one dg-require-effective-target and one dg-add-options and removing the explicit -march in advsimd-intrinsics/vector-complex_f16.c. Regtested on aarch64, and the Linaro CI also delivers a positive verdict for the relevant cortex-m33/-m3/-m55/-m7 configurations (after the accompanying patch to target-supports.exp that follows). Huge thanks to Christophe for testing this on arm. gcc/testsuite/ChangeLog: * gcc.dg/vect/complex/fast-math-bb-slp-complex-add-half-float.c: Adjust testcase. * gcc.dg/vect/complex/fast-math-bb-slp-complex-add-pattern-half-float.c: Likewise. * gcc.dg/vect/complex/fast-math-bb-slp-complex-mla-half-float.c: Likewise. * gcc.dg/vect/complex/fast-math-bb-slp-complex-mls-half-float.c: Likewise. * gcc.dg/vect/complex/fast-math-bb-slp-complex-mul-half-float.c: Likewise. * gcc.dg/vect/complex/fast-math-complex-add-half-float.c: Likewise. * gcc.dg/vect/complex/fast-math-complex-add-pattern-half-float.c: Likewise. * gcc.dg/vect/complex/fast-math-complex-mla-half-float.c: Likewise. * gcc.dg/vect/complex/fast-math-complex-mls-half-float.c: Likewise. * gcc.dg/vect/complex/fast-math-complex-mul-half-float.c: Likewise. * gcc.target/aarch64/advsimd-intrinsics/vector-complex_f16.c: Likewise.
