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/fsf-nsstring-format-1.m | 44 +++++++++++++++++++++++++++ 1 file changed, 44 insertions(+) create mode 100644 gcc/testsuite/objc.dg/fsf-nsstring-format-1.m (limited to 'gcc/testsuite/objc.dg/fsf-nsstring-format-1.m') diff --git a/gcc/testsuite/objc.dg/fsf-nsstring-format-1.m b/gcc/testsuite/objc.dg/fsf-nsstring-format-1.m new file mode 100644 index 000000000..0921bb33b --- /dev/null +++ b/gcc/testsuite/objc.dg/fsf-nsstring-format-1.m @@ -0,0 +1,44 @@ +/* Check NSString format extensions. */ +/* { dg-do compile { target *-*-darwin* } } */ +/* { dg-skip-if "" { *-*-* } { "-fgnu-runtime" } { "" } } */ +/* { dg-options "-Wall" } */ + +extern int printf (const char *fmt, ...); + +#ifndef __CONSTANT_CFSTRINGS__ +#error requires CFString +#endif + +typedef const struct __CFString * CFStringRef; +@class NSString; + +int s1 (NSString *fmt, ...) __attribute__((format(NSString, 1, 2))) ; /* OK */ +/* A CFString can represent an NSString. */ +int s1a (CFStringRef fmt, ...) __attribute__((format(NSString, 1, 2))) ; /* OK */ +/* But... it is possible that a CFString format might imply functionality that + is not present in objective-c. */ +int s1b (NSString *fmt, ...) __attribute__((format(CFString, 1, 2))) ; /* { dg-error "format argument should be a .CFString. reference" } */ + +int s2 (int a, NSString *fmt, ... ) __attribute__((format(__NSString__, 2, 3))) ; /* OK */ + +int s2a (int a, NSString *fmt, ... ) __attribute__((format(NSString, 2, 2))) ; /* { dg-error "format string argument follows the args to be formatted" } */ + +int s3 (const char *fmt, ... ) __attribute__((format(__NSString__, 1, 2))) ; /* { dg-error "format argument should be a .NSString. reference but a string was found" } */ +int s4 (NSString *fmt, ... ) __attribute__((format(printf, 1, 2))) ; /* { dg-error "found a .NSString. reference but the format argument should be a string" } */ + +char *s5 (char dum, char *fmt1, ... ) __attribute__((format_arg(2))) ; /* OK */ +NSString *s6 (NSString *dum, NSString *fmt1, ... ) __attribute__((format_arg(2))) ; /* OK */ + +char *s7 (int dum, void *fmt1, ... ) __attribute__((format_arg(2))) ; /* { dg-error "format string argument is not a string type" } */ +int s8 (NSString *dum, NSString *fmt1, ... ) __attribute__((format_arg(2))) ; /* { dg-error "function does not return string type" } */ + +char *s9 (int dum, char *fmt1, ... ) __attribute__((format_arg(2))) ; /* OK */ +NSString *s10 (int dum, NSString *fmt1, ... ) __attribute__((format_arg(2))) ; /* OK */ + +void foo (void) +{ + s1 (@"format not checked %d %s", 3, 4); + printf("this one is checked %d %s", 3, 4, 5); /* { dg-warning "format '%s' expects argument of type 'char .', but argument 3 has type 'int'" } */ + /* { dg-warning "too many arguments for format" "" { target *-*-* } 41 } */ + printf(s9 (1, "and so is this %d %d %s", 3, 4), 5, 6, 12); /* { dg-warning "format '%s' expects argument of type 'char .', but argument 4 has type 'int'" } */ +} -- cgit v1.2.3
