From 3c9378265a8633e2c85a393b54a16abcf64fe616 Mon Sep 17 00:00:00 2001 From: Joseph Myers Date: Wed, 11 Jan 2017 14:02:23 +0000 Subject: Fix testsuite build for GCC 7 -Wformat-truncation. This patch fixes the glibc testsuite build for GCC 7 -Wformat-truncation, newly moved out of -Wformat-length and with some further warnings that didn't previously appear. Two tests that previously disabled -Wformat-length are changed to disable -Wformat-truncation instead; two others are made to disable that option as well. Tested (compilation only) with build-many-glibcs.py for aarch64 with GCC mainline. * stdio-common/tst-printf.c [__GNUC_PREREQ (7, 0)]: Ignore -Wformat-truncation instead of -Wformat-length. * time/tst-strptime2.c (mkbuf) [__GNUC_PREREQ (7, 0)]: Likewise. * stdio-common/tstdiomisc.c (F): Ignore -Wformat-truncation for GCC 7. * wcsmbs/tst-wcstof.c: Include . (do_test): Ignore -Wformat-truncation for GCC 7. --- stdio-common/tst-printf.c | 5 +++-- 1 file changed, 3 insertions(+), 2 deletions(-) (limited to 'stdio-common/tst-printf.c') diff --git a/stdio-common/tst-printf.c b/stdio-common/tst-printf.c index 74150c5e54..719b3eb08c 100644 --- a/stdio-common/tst-printf.c +++ b/stdio-common/tst-printf.c @@ -33,8 +33,9 @@ DIAG_IGNORE_NEEDS_COMMENT (4.9, "-Wformat"); #if __GNUC_PREREQ (7, 0) -/* Compiler warnings about format lengths should also be ignored. */ -DIAG_IGNORE_NEEDS_COMMENT (7.0, "-Wformat-length"); +/* Compiler warnings about snprintf output truncation should also be + ignored. */ +DIAG_IGNORE_NEEDS_COMMENT (7.0, "-Wformat-truncation"); #endif static void rfg1 (void); -- cgit v1.2.3
