Subject: [PATCH v2] testsuite: [arm] Relax expected register names in MVE tests
Date: Fri, 30 Sep 2022 13:19:38 +0200 [thread overview]
Message-ID: <20220930111938.354664-1-christophe.lyon@arm.com> (raw)
In-Reply-To: <PAXPR08MB6926EF421DE84C4F6AF96B9493579@PAXPR08MB6926.eurprd08.prod.outlook.com>
These two tests have hardcoded q0 as destination/source of load/store
instructions, but this register is actually used only under
-mfloat-abi=hard. When using -mfloat-abi=softfp, other registers
(eg. q3) can be used to transfer function arguments from core
registers to MVE registers, making the expected regexp fail.
This small patch replaces q0 with q[0-7] to accept any 'q' register.
In several places where we had q[0-9]+, replace it with q[0-7] as MVE
only has q0-q7 registers.
OK for trunk?
gcc/testsuite/ChangeLog:
* gcc.target/arm/mve/mve_load_memory_modes.c: Update expected
registers.
* gcc.target/arm/mve/mve_store_memory_modes.c: Likewise.
