Janis,
We are seeing failures of the new decimal testcases on x86_64-apple-darwin10
which you committed into the libstdc++-v3 testsuite...

Are these tests entirely glibc-centric and shouldn't they be disabled for
darwin?

Each test contains
// { dg-require-effective-target-dfp }
which checks that the compiler supports modes SD, DD, and TD, which
in turn are supported if ENABLE_DECIMAL_FLOAT is defined within the
compiler. That should not be defined for darwin; I'll take a look.

I built a cross cc1plus for x86_64-apple-darwin10 and got the behavior
I expected. From $objdir/gcc:
elm3b149% fgrep -l ENABLE_DECIMAL_FLOAT *.h
auto-host.h:#define ENABLE_DECIMAL_FLOAT 0
elm3b149% echo "float x __attribute__((mode(DD)));" > x.c
elm3b149% ./cc1plus -quiet x.c
x.c:1:33: error: unable to emulate ‘DD’
Please try that little test with your cc1plus to see if the problem
is with your compiler not rejecting DD mode, or with the test
framework not handling it correctly.

Janis,
I find that ENABLE_DECIMAL_FLOAT is set to 0 on x86_64-apple-darwin10...
[MacPro:gcc45-4.4.999-20091005/darwin_objdir/gcc] root# grep ENABLE_DECIMAL_FLOAT auto-host.h
#define ENABLE_DECIMAL_FLOAT 0
and the test code fails to compile...
[MacPro:gcc45-4.4.999-20091005/darwin_objdir/gcc] root# echo "float x __attribute__((mode(DD)));" > x.c
[MacPro:gcc45-4.4.999-20091005/darwin_objdir/gcc] root# ./cc1plus -quiet x.c
x.c:1:33: error: unable to emulate ‘DD’
However, the testsuite failures still occurs as follows...

Oh, maybe the libstdc++ tests don't support dg-require-effective-target.

Janis,
Yes, doesn't it need something like...
# Skip these tests for targets that don't support this extension.
if { ![check_effective_target_dfp] } {
return;
}
which is in testsuite/gcc.dg/dfp/dfp.exp. I find...
grep -R check_effective_target_dfp testsuite | grep ".exp" | grep -v svn | grep -v Change

I spoke too soon. I'm now building a compiler with decimal float
disabled and will dig into this.

Janis,
Don't you have to include something like gcc/testsuite/lib/target-supports.exp
to be able to use check_effective_target_dfp? I am somewhat surprised that
the dejagnu harness didn't throw an error when trying to process...
// { dg-require-effective-target-dfp }
without having a "load_lib target-supports.exp" in the calling .exp script.

...means that it's the excess error that is the fail. Not the error.
On the brightside, the error is better now, I think.

I changed this from what Janis posted, so she is certainly not to blame
here. In any case, all you should have to do is add a new line for this
new error:

Because this is a flaw in the libstdc++-v3 testsuite harness
which obviously the core gcc testsuite handles properly. The
other gcc developers might have an insight on the best way
to fix this for libstdc++-v3 (since it appears you need some
of the procs from gcc/testsuite/lib/target-supports.exp).

Actually it's a flaw in my new tests, a missing space in
// { dg-require-effective-target dfp }
Patch will be checked in momentarily; sorry about that.
By the way, gcc/testsuite/lib/target-supports-dg.exp is
included indirectly, and the check doesn't look for any
specific error message.
