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/g++.dg/warn/format2.C | 32 ++++++++++++++++++++++++++++++++ 1 file changed, 32 insertions(+) create mode 100644 gcc/testsuite/g++.dg/warn/format2.C (limited to 'gcc/testsuite/g++.dg/warn/format2.C') diff --git a/gcc/testsuite/g++.dg/warn/format2.C b/gcc/testsuite/g++.dg/warn/format2.C new file mode 100644 index 000000000..639bc668b --- /dev/null +++ b/gcc/testsuite/g++.dg/warn/format2.C @@ -0,0 +1,32 @@ +// Test for format attributes: test applying them to types in C++. +// Origin: Joseph Myers +// { dg-do compile } +// { dg-options "-Wformat" } + +__attribute__((format(printf, 1, 2))) void (*tformatprintf0) (const char *, ...); +void (*tformatprintf1) (const char *, ...) __attribute__((format(printf, 1, 2))); +void (__attribute__((format(printf, 1, 2))) *tformatprintf2) (const char *, ...); +void (__attribute__((format(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
