Subject: arm: Update early-break tests to accept thumb output too.
X-Git-Tag: basepoints/gcc-15~3076
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=dac34a18148499b8a546b87f290dfc4f9a33cfe7;p=thirdparty%2Fgcc.git

arm: Update early-break tests to accept thumb output too.

The tests I recently added for early break fail in thumb mode
because in thumb mode `cbz/cbnz` exist and so the cmp+branch
is fused.  This updates the testcases to accept either output.

gcc/testsuite/ChangeLog:

	* gcc.target/arm/vect-early-break-cbranch.c: Accept thumb output.
