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/objc.dg/attributes/method-format-1.m | 43 ++++++++++++++++++++++ 1 file changed, 43 insertions(+) create mode 100644 gcc/testsuite/objc.dg/attributes/method-format-1.m (limited to 'gcc/testsuite/objc.dg/attributes/method-format-1.m') diff --git a/gcc/testsuite/objc.dg/attributes/method-format-1.m b/gcc/testsuite/objc.dg/attributes/method-format-1.m new file mode 100644 index 000000000..11ce8eebb --- /dev/null +++ b/gcc/testsuite/objc.dg/attributes/method-format-1.m @@ -0,0 +1,43 @@ +/* Contributed by Nicola Pero , October 2010. */ +/* { dg-do compile } */ +/* { dg-options "-Wall" } */ + +#include +#include + +@interface LogObject +{ + Class isa; +} ++ (void) log: (int)level message: (const char *) my_format, ... __attribute__ ((format (printf, 2, 3))); +- (void) log: (int)level message: (const char *) my_format, ... __attribute__ ((format (printf, 2, 3))); + ++ (void) debug: (const char *) my_format, ... __attribute__ ((format (printf, 1, 2))); +- (void) debug: (const char *) my_format, ... __attribute__ ((format (printf, 1, 2))); + +/* Just make sure a missing or invalid attribute won't crash the compiler. */ +- (void) log2: (int)level message: (const char *) my_format, ... __attribute__ ((format (printf, 2))); /* { dg-error "wrong" } */ ++ (void) debug2: (const char *) my_format, ... __attribute__ ((format (printf))); /* { dg-error "wrong" } */ +- (void) debug2: (const char *) my_format, ... __attribute__ ((format (printf))); /* { dg-error "wrong" } */ ++ (void) alert: (const char *) my_format __attribute__ ((format (printf, 1, 2))); /* { dg-error "args to be formatted is not ..." } */ +- (void) alert: (const char *) my_format __attribute__ ((format (printf, 1, 2))); /* { dg-error "args to be formatted is not ..." } */ +@end + +void test (LogObject *object) +{ + [object log: 2 message: "attribute only applies to variadic functions"]; + [object log: 2 message: "attribute %s only applies to variadic functions", "'format'"]; + [object log: 2 message: "attribute %s only applies to variadic functions"]; /* { dg-warning "expects a matching" } */ + + [object debug: "attribute only applies to variadic functions"]; + [object debug: "attribute %s only applies to variadic functions", "'format'"]; + [object debug: "attribute %s only applies to variadic functions"]; /* { dg-warning "expects a matching" } */ + + [LogObject log: 2 message: "attribute only applies to variadic functions"]; + [LogObject log: 2 message: "attribute %s only applies to variadic functions", "'format'"]; + [LogObject log: 2 message: "attribute %s only applies to variadic functions"]; /* { dg-warning "expects a matching" } */ + + [LogObject debug: "attribute only applies to variadic functions"]; + [LogObject debug: "attribute %s only applies to variadic functions", "'format'"]; + [LogObject debug: "attribute %s only applies to variadic functions"]; /* { dg-warning "expects a matching" } */ +} -- cgit v1.2.3
