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/i386/20020224-1.c | 41 ++++++++++++++++++++++++++++++ 1 file changed, 41 insertions(+) create mode 100644 gcc/testsuite/gcc.target/i386/20020224-1.c (limited to 'gcc/testsuite/gcc.target/i386/20020224-1.c') diff --git a/gcc/testsuite/gcc.target/i386/20020224-1.c b/gcc/testsuite/gcc.target/i386/20020224-1.c new file mode 100644 index 000000000..2905719fa --- /dev/null +++ b/gcc/testsuite/gcc.target/i386/20020224-1.c @@ -0,0 +1,41 @@ +/* PR target/5755 + This testcase failed because the caller of a function returning struct + expected the callee to pop up the hidden return structure pointer, + while callee was actually not poping it up (as the hidden argument + was passed in register). */ +/* { dg-do run } */ +/* { dg-options "-O2 -fomit-frame-pointer" } */ + +extern void abort (void); +extern void exit (int); + +typedef struct { + int a1, a2; +} A; + +A a; + +A __attribute__ ((regparm (2))) +foo (int x) +{ + return a; +} + +int __attribute__ ((regparm (2))) +bar (int x) +{ + int r = foo(0).a2; + return r; +} + +int +main () +{ + int f; + a.a1 = 530; + a.a2 = 980; + f = bar (0); + if (f != 980) + abort (); + exit (0); +} -- cgit v1.2.3
