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.target/powerpc/ppc-stackalign-1.c | 35 ++++++++++++++++++++++ 1 file changed, 35 insertions(+) create mode 100644 gcc/testsuite/gcc.target/powerpc/ppc-stackalign-1.c (limited to 'gcc/testsuite/gcc.target/powerpc/ppc-stackalign-1.c') diff --git a/gcc/testsuite/gcc.target/powerpc/ppc-stackalign-1.c b/gcc/testsuite/gcc.target/powerpc/ppc-stackalign-1.c new file mode 100644 index 000000000..465fc41e1 --- /dev/null +++ b/gcc/testsuite/gcc.target/powerpc/ppc-stackalign-1.c @@ -0,0 +1,35 @@ +/* { dg-do run { target powerpc*-*-linux* powerpc*-*-eabi* } } */ +/* { dg-options {} } */ + +/* Test stack pointer alignment against variable alloca. */ +/* Inspired by PR libgcj/10610. */ +/* Origin: Franz Sirl . */ + +extern void abort (void); +extern void exit (int); + +register unsigned long sp __asm__ ("r1"); + +void g (int * val __attribute__ ((unused))) +{ + if (sp & 0xf) + abort (); +} + +void f (int val) +{ + int *val1 = __builtin_alloca (val); + + g (val1); + return; +} + +int main (void) +{ + int i; + + for (i = 1; i < 32; i++) + f (i); + + exit (0); +} -- cgit v1.2.3
