Subject: [PATCH] [PR51534] [arm] split out pr51534 test for softfp
Date: Fri, 17 Feb 2023 04:13:52 -0300 [thread overview]
Message-ID: <orbklssr0v.fsf@lxoliva.fsfla.org> (raw)
The test uses arm_hard_ok and arm_softfp_ok as if they were mutually
exclusive, but they test whether the corresponding -mfloat-abi= flag
is usable, not whether it is in effect, so it is possible for both to
pass, and then the test comes out with incorrect expectations
whichever the default float-abi is.
Separate the test into hard and softfp variants, and extend the softfp
variant to accept both ARM and Thumb opcodes; it unwarrantedly assumed
the latter.
Regstrapped on x86_64-linux-gnu.
Tested on arm-vxworks7 (gcc-12) and arm-eabi (trunk). Ok to install?

* gcc.target/arm/pr51534s.c: ... this, and support ARM too.
