[Bug testsuite/35538] New: FAIL: gcc.dg/tree-ssa/ssa-store-ccp-4.c scan-tree-dump-times optimized "conststaticvariable" 1

[dominiq at lps dot ens dot fr]

On (powerpc|i686)-apple-darwin9 I see the following failure in 32 and 64 bit
modes:

FAIL: gcc.dg/tree-ssa/ssa-store-ccp-4.c scan-tree-dump-times optimized
"conststaticvariable" 1

[ibook-dhum] test/tmp% cat ssa-store-ccp-4.c.127t.optimized

;; Function f (f)

Analyzing Edge Insertions.
f ()
{
<bb 2>:
  return 0;

}

Is this a bug in gcc or in the testsuite?

It looks like variables in a shared library can't be overridden
at run time on MacOS. You can skip or xfail it for MacOS.

There are also issues with ssa-store-cpp-3.c and -fpic on i686 and x86_64
linux:

I have noticed the same issue on i686-apple-darwin9:

http://gcc.gnu.org/ml/gcc-testresults/2008-03/msg00841.html

The config is:

configure flags: --build=i686-apple-darwin9 --host=i686-apple-darwin9
--target=i686-apple-darwin9 --with-gnu-as --enable-shared
--prefix=/opt/gnu/gcc/gcc-4.4.0 --with-gmp=/opt/gnu/gcc/gcc-4.4.0
--enable-debug=no --disable-nls
--enable-languages=c,c++,objc,fortran,ada,obj-c++,java

compared to mine:

configure flags: --prefix=/opt/gcc/gcc4.4w --mandir=/opt/gcc/gcc4.4w/share/man
--infodir=/opt/gcc/gcc4.4w/share/info --build=i686-apple-darwin9

I have now on i686-apple-darwin9 32 bit mode:

FAIL: gcc.dg/tree-ssa/ssa-store-ccp-3.c scan-tree-dump-times optimized
"conststaticvariable" 1

while the failure for gcc.dg/tree-ssa/ssa-store-ccp-4.c is gone.

I guess we have to skip this one on darwin.

On hppa64-hp-hpux11.11,

FAIL: gcc.dg/tree-ssa/ssa-store-ccp-3.c scan-tree-dump-times optimized
"conststa
ticvariable" 1

The tree dump is the same as for darwin.  This target is always pic.
