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-7.c | 35 +++++++++++++++++++++++++++++++++++ 1 file changed, 35 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/format/attr-7.c (limited to 'gcc/testsuite/gcc.dg/format/attr-7.c') diff --git a/gcc/testsuite/gcc.dg/format/attr-7.c b/gcc/testsuite/gcc.dg/format/attr-7.c new file mode 100644 index 000000000..c37044819 --- /dev/null +++ b/gcc/testsuite/gcc.dg/format/attr-7.c @@ -0,0 +1,35 @@ +/* Test for format attributes: test applying them to types. */ +/* Origin: Joseph Myers */ +/* { dg-do compile } */ +/* { dg-options "-std=gnu99 -Wformat" } */ + +#define DONT_GNU_PROTOTYPE +#include "format.h" + +__attribute__((format(gnu_attr_printf, 1, 2))) void (*tformatprintf0) (const char *, ...); +void (*tformatprintf1) (const char *, ...) __attribute__((format(gnu_attr_printf, 1, 2))); +void (__attribute__((format(gnu_attr_printf, 1, 2))) *tformatprintf2) (const char *, ...); +void (__attribute__((format(gnu_attr_printf, 1, 2))) ****tformatprintf3) (const char *, ...); + +char * (__attribute__((format_arg(1))) *tformat_arg) (const char *); + +void +baz (int i) +{ + (*tformatprintf0) ("%d", i); + (*tformatprintf0) ((*tformat_arg) ("%d"), i); + (*tformatprintf0) ("%"); /* { dg-warning "format" "prefix" } */ + (*tformatprintf0) ((*tformat_arg) ("%")); /* { dg-warning "format" "prefix" } */ + (*tformatprintf1) ("%d", i); + (*tformatprintf1) ((*tformat_arg) ("%d"), i); + (*tformatprintf1) ("%"); /* { dg-warning "format" "postfix" } */ + (*tformatprintf1) ((*tformat_arg) ("%")); /* { dg-warning "format" "postfix" } */ + (*tformatprintf2) ("%d", i); + (*tformatprintf2) ((*tformat_arg) ("%d"), i); + (*tformatprintf2) ("%"); /* { dg-warning "format" "nested" } */ + (*tformatprintf2) ((*tformat_arg) ("%")); /* { dg-warning "format" "nested" } */ + (****tformatprintf3) ("%d", i); + (****tformatprintf3) ((*tformat_arg) ("%d"), i); + (****tformatprintf3) ("%"); /* { dg-warning "format" "nested 2" } */ + (****tformatprintf3) ((*tformat_arg) ("%")); /* { dg-warning "format" "nested 2" } */ +} -- cgit v1.2.3
