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/c90-intprom-1.c | 47 ++++++++++++++++++++++++++++++++++++ 1 file changed, 47 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/c90-intprom-1.c (limited to 'gcc/testsuite/gcc.dg/c90-intprom-1.c') diff --git a/gcc/testsuite/gcc.dg/c90-intprom-1.c b/gcc/testsuite/gcc.dg/c90-intprom-1.c new file mode 100644 index 000000000..78e4b39ef --- /dev/null +++ b/gcc/testsuite/gcc.dg/c90-intprom-1.c @@ -0,0 +1,47 @@ +/* Test for integer promotion rules: C90 subset of types. */ +/* Origin: Joseph Myers */ +/* { dg-do compile } */ +/* { dg-options "-std=iso9899:1990 -pedantic-errors" } */ + +#include + +#define CHECK(T1, T2, TC) \ + do { \ + T1 a = 0; \ + T2 b = 0; \ + TC *c = 0; \ + __typeof__(a+b) *d = 0; \ + c = d; \ + d = c; \ + } while (0) + +void +f (void) +{ + /* One type is unsigned long. */ + CHECK(unsigned long, unsigned long, unsigned long); + CHECK(unsigned int, unsigned long, unsigned long); + CHECK(unsigned long, unsigned int, unsigned long); + CHECK(int, unsigned long, unsigned long); + CHECK(long, unsigned long, unsigned long); + CHECK(unsigned long, int, unsigned long); + CHECK(unsigned long, long, unsigned long); + /* long and unsigned int. */ +#if LONG_MAX >= UINT_MAX + CHECK(unsigned int, long, long); + CHECK(long, unsigned int, long); +#else + CHECK(unsigned int, long, unsigned long); + CHECK(long, unsigned int, unsigned long); +#endif + /* One type is long. */ + CHECK(long, long, long); + CHECK(int, long, long); + CHECK(long, int, long); + /* One type is unsigned int. */ + CHECK(unsigned int, unsigned int, unsigned int); + CHECK(int, unsigned int, unsigned int); + CHECK(unsigned int, int, unsigned int); + /* Otherwise int. */ + CHECK(int, int, int); +} -- cgit v1.2.3
