From c8f7324e81c1bb7093a5b44317af385e5774f9a3 Mon Sep 17 00:00:00 2001 From: Xi Ruoyao Date: Sat, 9 Apr 2022 01:58:40 +0800 Subject: [PATCH] loongarch: testsuite: adapt stack-usage-1.c for LP64 LoongArch backend allocates two additional 8-byte stack slots for LP64, one for saving $fp and another for saving the temporary value "1". Ideally they are both unneeded, but (1) we're using -O0 so the code is suboptimized by the nature; (2) any improvement (if possible) should be deferred to GCC 13. So for now simply adjust the test to make it pass. gcc/testsuite/ * gcc.dg/stack-usage-1.c: Adjust for LoongArch LP64. --- gcc/testsuite/gcc.dg/stack-usage-1.c | 2 ++ 1 file changed, 2 insertions(+) diff --git a/gcc/testsuite/gcc.dg/stack-usage-1.c b/gcc/testsuite/gcc.dg/stack-usage-1.c index 1d7d1fe..21cce0f 100644 --- a/gcc/testsuite/gcc.dg/stack-usage-1.c +++ b/gcc/testsuite/gcc.dg/stack-usage-1.c @@ -105,6 +105,8 @@ # define SIZE 252 #elif defined (__CRIS__) # define SIZE 252 +#elif defined (__loongarch_lp64) +# define SIZE 240 /* 256 - 8 bytes for $fp, and 8 bytes for a temp value */ #else # define SIZE 256 #endif -- 2.7.4
