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/torture/mips-hilo-2.c | 27 +++++++++++++++++++++++++++ 1 file changed, 27 insertions(+) create mode 100644 gcc/testsuite/gcc.dg/torture/mips-hilo-2.c (limited to 'gcc/testsuite/gcc.dg/torture/mips-hilo-2.c') diff --git a/gcc/testsuite/gcc.dg/torture/mips-hilo-2.c b/gcc/testsuite/gcc.dg/torture/mips-hilo-2.c new file mode 100644 index 000000000..dbe949307 --- /dev/null +++ b/gcc/testsuite/gcc.dg/torture/mips-hilo-2.c @@ -0,0 +1,27 @@ +/* Due to a reload inheritance bug, the asm statement in f() would be passed + the low part of u.ll on little-endian 32-bit targets. */ +/* { dg-do run { target mips*-*-* } } */ + +extern void abort (void); +extern void exit (int); + +unsigned int g; + +unsigned __attribute__ ((nomips16)) long long f (unsigned int x) +{ + union { unsigned long long ll; unsigned int parts[2]; } u; + + u.ll = ((unsigned long long) x * x); + asm ("mflo\t%0" : "=r" (g) : "l" (u.parts[1])); + return u.ll; +} + +int __attribute__ ((nomips16)) main () +{ + union { unsigned long long ll; unsigned int parts[2]; } u; + + u.ll = f (0x12345678); + if (g != u.parts[1]) + abort (); + exit (0); +} -- cgit v1.2.3
