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/miss-format-3.C | 27 +++++++++++++++++++++++++++ 1 file changed, 27 insertions(+) create mode 100644 gcc/testsuite/g++.dg/warn/miss-format-3.C (limited to 'gcc/testsuite/g++.dg/warn/miss-format-3.C') diff --git a/gcc/testsuite/g++.dg/warn/miss-format-3.C b/gcc/testsuite/g++.dg/warn/miss-format-3.C new file mode 100644 index 000000000..d131d1511 --- /dev/null +++ b/gcc/testsuite/g++.dg/warn/miss-format-3.C @@ -0,0 +1,27 @@ +/* Test warnings for missing format attributes on function pointers. */ +/* Origin: Kaveh Ghazi */ +/* { dg-do compile } */ +/* { dg-options "-Wmissing-format-attribute" } */ +/* { dg-options "-Wmissing-format-attribute -Wno-abi" { target arm_eabi } } */ + +#include + +typedef void (*noattr_t) (const char *, ...); +typedef noattr_t __attribute__ ((__format__(__printf__, 1, 2))) attr_t; + +typedef void (*vnoattr_t) (const char *, va_list); +typedef vnoattr_t __attribute__ ((__format__(__printf__, 1, 0))) vattr_t; + +void +foo1 (noattr_t na, attr_t a, vnoattr_t vna, vattr_t va) +{ + noattr_t na1 = na; + noattr_t na2 = a; /* { dg-warning "candidate" "initialization warning" } */ + attr_t a1 = na; + attr_t a2 = a; + + vnoattr_t vna1 = vna; + vnoattr_t vna2 = va; /* { dg-warning "candidate" "initialization warning" } */ + vattr_t va1 = vna; + vattr_t va2 = va; +} -- cgit v1.2.3
