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. --- time/tst-strptime2.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'time') diff --git a/time/tst-strptime2.c b/time/tst-strptime2.c index 04f7cff437..9273568b6f 100644 --- a/time/tst-strptime2.c +++ b/time/tst-strptime2.c @@ -73,7 +73,7 @@ mkbuf (char *buf, bool neg, bool colon, unsigned int hhmm, size_t ndigits) This test is explicitly using short buffers to force snprintf to truncate the output so we ignore the warnings. */ DIAG_PUSH_NEEDS_COMMENT; - DIAG_IGNORE_NEEDS_COMMENT (7.0, "-Wformat-length"); + DIAG_IGNORE_NEEDS_COMMENT (7.0, "-Wformat-truncation"); #endif if (colon) snprintf (buf + i, ndigits + 2, "%02u:%02u", hh, mm); -- cgit 1.4.1
