Subject: Re: [PATCH rs6000] Fix for builtins-4-runnable.c testcase FAIL on power7/BE 32-bit
Date: Fri, 09 Feb 2018 22:09:00 -0000	[thread overview]
Message-ID: <1518214146.7508.7.camel@us.ibm.com> (raw)
In-Reply-To: <1518193377.7508.2.camel@us.ibm.com>

GCC maintainers:

As pointed out, the dg arguments in new test file was missing the
{target 128}.  I updated the arguments to be 

    { dg-do run { target { int128 && powerpc64*-*-* } } }

Without the powerpc64*-*-* the test was still tried to compiled the
test case in 32-bit mode on BE and failed.

I reran the tests manually to verify the tests run as expected.  On a
Power 8 BE machine with GCC configured for -m32 and -m64 I ran:
     
    make -k check-gcc RUNTESTFLAGS="--target_board=unix'{-m32,-m64}' 
    powerpc.exp=builtins-4-int128-runnable.c" > out

The pertinent output was:
