Subject: testsuite: arm: add -mcpu=unset before -march
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=45fb81866b48a6231ca731d6656f248d951ae069;p=thirdparty%2Fgcc.git

testsuite: arm: add -mcpu=unset before -march

Reset the cpu selection to the default on tests that set -march
explicitly instead of using dg-add-options.  The latter would reset
the cpu selection to avoid interference from TOOL_OPTIONS.

Also add +fp to -march in tests that don't override float-abi and fpu,
so that -mfloat-abi=hard -mfpu=auto in TOOL_OPTIONS won't cause a
failure.


for  gcc/testsuite/ChangeLog

	* gcc.target/arm/bfloat16_simd_1_2.c: Add -mcpu=unset.
	* gcc.target/arm/bfloat16_simd_2_2.c: Likewise.
	* gcc.target/arm/bfloat16_simd_3_2.c: Likewise.
	* gcc.dg/torture/pr120347.c: Likewise.  Add +fp to -march.
