Subject: testsuite: require arm_v8_3a_fp16_complex_neon for complex fp16 tests
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=31875b910c70dd1e65d4da67562ac02b9b108c68;p=thirdparty%2Fgcc.git

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.
