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/builtins-30.c | 27 +++++++++++++++++++++++++++ 1 file changed, 27 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/builtins-30.c (limited to 'gcc/testsuite/gcc.dg/builtins-30.c') diff --git a/gcc/testsuite/gcc.dg/builtins-30.c b/gcc/testsuite/gcc.dg/builtins-30.c new file mode 100644 index 000000000..37e5dba2d --- /dev/null +++ b/gcc/testsuite/gcc.dg/builtins-30.c @@ -0,0 +1,27 @@ +/* { dg-do compile } */ +/* { dg-options "-Wall -Wshadow -fshow-column" } */ + +extern double strtod (const char *, char **); +#define UNUSED __attribute__ ((unused)) + +/* A built-in function may be overridden by an old-style definition + specifying too few arguments... */ +double cos () /* { dg-warning "shadows a built-in|number of arguments" } */ +{ + return strtod ("nan", 0); +} + +/* the right number, but the wrong type, arguments... */ +double sin (foo) /* { dg-warning "8:shadows a built-in" } */ + int foo UNUSED; /* { dg-warning "10:argument 'foo' doesn't match built-in prototype" } */ +{ + return strtod ("nan", 0); +} + +/* or too many arguments. */ +long double cosl (foo, bar) /* { dg-warning "shadows a built-in|number of arguments" } */ + const char *foo UNUSED; /* { dg-warning "18:argument 'foo' doesn't match" } */ + int bar UNUSED; +{ + return strtod ("nan", 0); +} -- cgit v1.2.3
