From 554fd8c5195424bdbcabf5de30fdc183aba391bd Mon Sep 17 00:00:00 2001 From: upstream source tree Date: Sun, 15 Mar 2015 20:14:05 -0400 Subject: obtained gcc-4.6.4.tar.bz2 from upstream website; verified gcc-4.6.4.tar.bz2.sig; imported gcc-4.6.4 source tree from verified upstream tarball. downloading a git-generated archive based on the 'upstream' tag should provide you with a source tree that is binary identical to the one extracted from the above tarball. if you have obtained the source via the command 'git clone', however, do note that line-endings of files in your working directory might differ from line-endings of the respective files in the upstream repository. --- gcc/testsuite/gcc.dg/format/attr-4.c | 26 ++++++++++++++++++++++++++ 1 file changed, 26 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/format/attr-4.c (limited to 'gcc/testsuite/gcc.dg/format/attr-4.c') diff --git a/gcc/testsuite/gcc.dg/format/attr-4.c b/gcc/testsuite/gcc.dg/format/attr-4.c new file mode 100644 index 000000000..caeed93a7 --- /dev/null +++ b/gcc/testsuite/gcc.dg/format/attr-4.c @@ -0,0 +1,26 @@ +/* Test for format attributes: test use of __attribute__ + in prefix attributes. */ +/* Origin: Joseph Myers */ +/* { dg-do compile } */ +/* { dg-options "-std=gnu99 -Wformat" } */ + +#define DONT_GNU_PROTOTYPE +#include "format.h" + +extern __attribute__((format(gnu_attr_printf, 1, 2))) void tformatprintf0 (const char *, ...); +extern void __attribute__((format(gnu_attr_printf, 1, 2))) tformatprintf1 (const char *, ...); +extern void foo (void), __attribute__((format(gnu_attr_printf, 1, 2))) tformatprintf2 (const char *, ...); +extern __attribute__((noreturn)) void bar (void), __attribute__((format(gnu_attr_printf, 1, 2))) tformatprintf3 (const char *, ...); + +void +baz (int i, int *ip, double d) +{ + tformatprintf0 ("%d", i); + tformatprintf0 ("%"); /* { dg-warning "format" "attribute format printf case 0" } */ + tformatprintf1 ("%d", i); + tformatprintf1 ("%"); /* { dg-warning "format" "attribute format printf case 1" } */ + tformatprintf2 ("%d", i); + tformatprintf2 ("%"); /* { dg-warning "format" "attribute format printf case 2" } */ + tformatprintf3 ("%d", i); + tformatprintf3 ("%"); /* { dg-warning "format" "attribute format printf case 3" } */ +} -- cgit v1.2.3
