Subject: testsuite: Enable the PR 87600 tests for LoongArch
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=651845ceaae26a1b2c03f215e16e7e711dcea2cc;p=thirdparty%2Fgcc.git

testsuite: Enable the PR 87600 tests for LoongArch

I'm going to refine a part of the PR 87600 fix which seems triggering
PR 120983 that LoongArch is particularly suffering.  Enable the PR 87600
tests so I'll not regress PR 87600.

gcc/testsuite/ChangeLog:

	PR rtl-optimization/87600
	PR rtl-optimization/120983
	* gcc.dg/pr87600.h [__loongarch__]: Define REG0 and REG1.
	* gcc.dg/pr87600-1.c (dg-do): Add loongarch.
	* gcc.dg/pr87600-2.c (dg-do): Likewise.
