From 603af25815523ba9e39e9b441cde5308423a9238 Mon Sep 17 00:00:00 2001 From: Rainer Orth Date: Wed, 23 Nov 2022 21:54:26 +0100 Subject: [PATCH] analyzer: Use __builtin_alloca in gcc.dg/analyzer/call-summaries-2.c gcc.dg/analyzer/call-summaries-2.c currently FAILs on Solaris: FAIL: gcc.dg/analyzer/call-summaries-2.c (test for excess errors) Excess errors: /vol/gcc/src/hg/master/local/gcc/testsuite/gcc.dg/analyzer/call-summaries-2.c:468:12: warning: implicit declaration of function 'alloca' [-Wimplicit-function-declaration] /vol/gcc/src/hg/master/local/gcc/testsuite/gcc.dg/analyzer/call-summaries-2.c:468:12: warning: incompatible implicit declaration of built-in function 'alloca' [-Wbuiltin-declaration-mismatch] alloca is only declared in , which isn't included indirectly anywhere. To avoid this, I switched the test to use __builtin_alloca instead, following the vast majority of analyzer tests that use alloca. Tested no i386-pc-solaris2.11, sparc-sun-solaris2.11, and x86_64-pc-linux-gnu. 2022-11-23 Rainer Orth gcc/testsuite: * gcc.dg/analyzer/call-summaries-2.c (uses_alloca): Use __builtin_alloca instead of alloca. --- gcc/testsuite/gcc.dg/analyzer/call-summaries-2.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/gcc/testsuite/gcc.dg/analyzer/call-summaries-2.c b/gcc/testsuite/gcc.dg/analyzer/call-summaries-2.c index 85cece7..953cbd3 100644 --- a/gcc/testsuite/gcc.dg/analyzer/call-summaries-2.c +++ b/gcc/testsuite/gcc.dg/analyzer/call-summaries-2.c @@ -465,7 +465,7 @@ int test_returns_external_result (void) int uses_alloca (int i) { - int *p = alloca (sizeof (int)); + int *p = __builtin_alloca (sizeof (int)); *p = i; return *p; } -- 2.7.4
