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.c-torture/compile/20020312-1.c | 25 ++++++++++++++++++++++++ 1 file changed, 25 insertions(+) create mode 100644 gcc/testsuite/gcc.c-torture/compile/20020312-1.c (limited to 'gcc/testsuite/gcc.c-torture/compile/20020312-1.c') diff --git a/gcc/testsuite/gcc.c-torture/compile/20020312-1.c b/gcc/testsuite/gcc.c-torture/compile/20020312-1.c new file mode 100644 index 000000000..bb950ff31 --- /dev/null +++ b/gcc/testsuite/gcc.c-torture/compile/20020312-1.c @@ -0,0 +1,25 @@ +/* This does not compile on HC11/HC12 due to the asm which requires + two 32-bit registers. */ +/* { dg-do assemble } */ +/* { dg-xfail-if "" { m6811-*-* m6812-*-* } { "*" } { "" } } */ +/* { dg-skip-if "" { pdp11-*-* } { "-O0" } { "" } } */ + +/* PR optimization/5892 */ +typedef struct { unsigned long a; unsigned int b, c; } A; +typedef struct { unsigned long a; A *b; int c; } B; + +static inline unsigned int +bar (unsigned int x) +{ + unsigned long r; + asm ("" : "=r" (r) : "0" (x)); + return r >> 31; +} + +int foo (B *x) +{ + A *y; + y = x->b; + y->b = bar (x->c); + y->c = ({ unsigned int z = 1; (z << 24) | (z >> 24); }); +} -- cgit v1.2.3
