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.target/i386/pr48721.c | 51 +++++++++++++++++++++++++++++++++ 1 file changed, 51 insertions(+) create mode 100644 gcc/testsuite/gcc.target/i386/pr48721.c (limited to 'gcc/testsuite/gcc.target/i386/pr48721.c') diff --git a/gcc/testsuite/gcc.target/i386/pr48721.c b/gcc/testsuite/gcc.target/i386/pr48721.c new file mode 100644 index 000000000..f37a16949 --- /dev/null +++ b/gcc/testsuite/gcc.target/i386/pr48721.c @@ -0,0 +1,51 @@ +/* PR rtl-optimization/48721 */ +/* { dg-do compile } */ +/* { dg-options "-O -foptimize-sibling-calls -fsched2-use-superblocks -fschedule-insns2 -mtune=core2" } */ + +extern unsigned char a[]; +extern int b[], d[], e[], f[], g[], *h[], m[], *n[], o[]; +extern char c[]; + +struct S +{ + unsigned char s1; + int s2, s3, s4, s5, s6, s7, s8; +}; + +__attribute__((noinline, noclone)) int +foo (int x) +{ + return 0; +} + +int +bar (int x, struct S *y) +{ + int z; + switch (x) + { + case 1: + case 2: + { + int t2, t4, t5, t6, t7, t8; + z = o[y->s8 * 6]; + t8 = *n[m[x] * 5]; + t4 = *h[y->s7]; + t7 = z; + z = g[f[x] + y->s6]; + t6 = e[y->s5]; + t5 = d[c[x] + y->s3 * 17]; + if (z) + t2 = b[z]; + if (a[z] != y->s1) + return foo (x); + y->s8 = t8; + y->s4 = t4; + y->s7 = t7; + y->s6 = t6; + y->s5 = t5; + y->s2 = t2; + } + } + return 0; +} -- cgit v1.2.3
