Subject: [PATCH] arm: testuite: Missing optimization pattern for rev16 with
thumb1
This patch marks a rev16 test as XFAIL for architectures having only
Thumb1 support. The generated code is functionally correct, but the
optimization is disabled when -mthumb is equivalent to Thumb1. Fixing
the root issue would requires changes that are not suitable for GCC14
stage 4. More information at
https://linaro.atlassian.net/browse/GNU-1141
gcc/testsuite/ChangeLog:
* gcc.target/arm/rev16_2.c: XFAIL when compiled with Thumb1.
