Re: [patch, testsuite] Applying non_bionic effective target to particular tests


Hi Joseph,

I seem to address what you've said.

Except for I still left non_bionic check for three tests
(Namely: builtins-67.c, strlenopt-14g.c, strlenopt-14gf.c)

because checks for the presence of mempcpy, stpcpy and rintl (sorry, I
didn't mention it last time)
seem to be very narrow, I don't think they would bring any value.


I tested 'make check' on x86_64-unknown-linux-gnu and i686-pc-linux-android.


2014-08-15  Alexander Ivchenko  <alexander.ivchenko@intel.com>

       * lib/target-supports.exp (error_h): New check.
       (libc_has_complex_functions): Ditto.
       (tgmath_h): Ditto.
       * gcc.dg/builtins-59.c: Add libc_has_complex_functions check.
       * gcc.dg/builtins-61.c: Likewise.
       * gcc.dg/builtins-67.c: Disable test for Bionic.
       * gcc.dg/strlenopt-14g.c: Likewise.
       * gcc.dg/strlenopt-14gf.c: Likewise.
       * gcc.dg/c99-tgmath-1.c: Add tgmath_h check.
       * gcc.dg/c99-tgmath-2.c: Likewise.
       * gcc.dg/c99-tgmath-3.c: Likewise.
       * gcc.dg/c99-tgmath-4.c: Likewise.
       * gcc.dg/dfp/convert-dfp-round-thread.c: Add error_h check.


Here is the updated patch:
