From: Matthieu Longo Date: Thu, 8 Feb 2024 18:13:49 +0000 (+0000) Subject: arm: testuite: Missing optimization pattern for rev16 with thumb1 X-Git-Tag: basepoints/gcc-15~1129 X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=2acf478bf10fc38e9cbce77ac5ecaf5abfb724b1;p=thirdparty%2Fgcc.git 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.
