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/execute/20030613-1.c | 62 ++++++++++++++++++++++++ 1 file changed, 62 insertions(+) create mode 100644 gcc/testsuite/gcc.c-torture/execute/20030613-1.c (limited to 'gcc/testsuite/gcc.c-torture/execute/20030613-1.c') diff --git a/gcc/testsuite/gcc.c-torture/execute/20030613-1.c b/gcc/testsuite/gcc.c-torture/execute/20030613-1.c new file mode 100644 index 000000000..cb1623d96 --- /dev/null +++ b/gcc/testsuite/gcc.c-torture/execute/20030613-1.c @@ -0,0 +1,62 @@ +/* PR optimization/10955 */ +/* Originator: */ + +/* This used to fail on SPARC32 at -O3 because the loop unroller + wrongly thought it could eliminate a pseudo in a loop, while + the pseudo was used outside the loop. */ + +extern void abort(void); + +#define COMPLEX struct CS + +COMPLEX { + long x; + long y; +}; + + +static COMPLEX CCID (COMPLEX x) +{ + COMPLEX a; + + a.x = x.x; + a.y = x.y; + + return a; +} + + +static COMPLEX CPOW (COMPLEX x, int y) +{ + COMPLEX a; + a = x; + + while (--y > 0) + a=CCID(a); + + return a; +} + + +static int c5p (COMPLEX x) +{ + COMPLEX a,b; + a = CPOW (x, 2); + b = CCID( CPOW(a,2) ); + + return (b.x == b.y); +} + + +int main (void) +{ + COMPLEX x; + + x.x = -7; + x.y = -7; + + if (!c5p(x)) + abort(); + + return 0; +} -- cgit v1.2.3
