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/pr27285.c | 46 +++++++++++++++++++++++++++ 1 file changed, 46 insertions(+) create mode 100644 gcc/testsuite/gcc.c-torture/execute/pr27285.c (limited to 'gcc/testsuite/gcc.c-torture/execute/pr27285.c') diff --git a/gcc/testsuite/gcc.c-torture/execute/pr27285.c b/gcc/testsuite/gcc.c-torture/execute/pr27285.c new file mode 100644 index 000000000..44a6aaf0f --- /dev/null +++ b/gcc/testsuite/gcc.c-torture/execute/pr27285.c @@ -0,0 +1,46 @@ +/* PR tree-optimization/27285 */ + +extern void abort (void); + +struct S { unsigned char a, b, c, d[16]; }; + +void __attribute__ ((noinline)) +foo (struct S *x, struct S *y) +{ + int a, b; + unsigned char c, *d, *e; + + b = x->b; + d = x->d; + e = y->d; + a = 0; + while (b) + { + if (b >= 8) + { + c = 0xff; + b -= 8; + } + else + { + c = 0xff << (8 - b); + b = 0; + } + + e[a] = d[a] & c; + a++; + } +} + +int +main (void) +{ + struct S x = { 0, 25, 0, { 0xaa, 0xbb, 0xcc, 0xdd }}; + struct S y = { 0, 0, 0, { 0 }}; + + foo (&x, &y); + if (x.d[0] != y.d[0] || x.d[1] != y.d[1] + || x.d[2] != y.d[2] || (x.d[3] & 0x80) != y.d[3]) + abort (); + return 0; +} -- cgit v1.2.3
