From 36507a2c9cbac673553b043aa1817e674836c232 Mon Sep 17 00:00:00 2001 From: Kwok Cheung Yeung Date: Wed, 12 Aug 2020 05:19:11 -0700 Subject: [PATCH] Fix gcc.dg/ia64-sync-5.c for architectures with unsigned char as default (PR 96519) If char is unsigned, then comparisons of the char array elements against negative integers in the test will fail as values in the array will always be positive, and will remain so when promoted to signed int. 2020-08-12 Kwok Cheung Yeung PR testsuite/96519 gcc/testsuite/ * gcc.dg/ia64-sync-5.c (AC, init_qi, test_qi): Change element type to signed char. --- gcc/testsuite/gcc.dg/ia64-sync-5.c | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) diff --git a/gcc/testsuite/gcc.dg/ia64-sync-5.c b/gcc/testsuite/gcc.dg/ia64-sync-5.c index 8b16b29b20e..a3923b06b35 100644 --- a/gcc/testsuite/gcc.dg/ia64-sync-5.c +++ b/gcc/testsuite/gcc.dg/ia64-sync-5.c @@ -14,9 +14,9 @@ extern void abort (void); extern void *memcpy (void *, const void *, size_t); extern int memcmp (const void *, const void *, size_t); -static char AC[4]; -static char init_qi[4] = { -30,-30,-50,-50 }; -static char test_qi[4] = { -115,-115,25,25 }; +static signed char AC[4]; +static signed char init_qi[4] = { -30,-30,-50,-50 }; +static signed char test_qi[4] = { -115,-115,25,25 }; static void do_qi (void) -- 2.30.2
