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/20020206-2.c | 24 ++++++++++++++++++++++++ 1 file changed, 24 insertions(+) create mode 100644 gcc/testsuite/gcc.c-torture/execute/20020206-2.c (limited to 'gcc/testsuite/gcc.c-torture/execute/20020206-2.c') diff --git a/gcc/testsuite/gcc.c-torture/execute/20020206-2.c b/gcc/testsuite/gcc.c-torture/execute/20020206-2.c new file mode 100644 index 000000000..097eb3055 --- /dev/null +++ b/gcc/testsuite/gcc.c-torture/execute/20020206-2.c @@ -0,0 +1,24 @@ +/* Origin: PR c/5420 from David Mosberger . + This testcase was miscompiled when tail call optimizing, because a + compound literal initialization was emitted only in the tail call insn + chain, not in the normal call insn chain. */ + +typedef struct { unsigned short a; } A; + +extern void abort (void); +extern void exit (int); + +void foo (unsigned int x) +{ + if (x != 0x800 && x != 0x810) + abort (); +} + +int +main (int argc, char **argv) +{ + int i; + for (i = 0; i < 2; ++i) + foo (((A) { ((!(i >> 4) ? 8 : 64 + (i >> 4)) << 8) + (i << 4) } ).a); + exit (0); +} -- cgit v1.2.3
