Thomas Schwinge 3fa8bff30a New effective-target 'asm_goto_with_outputs' 
After commit e16f90be2d
"testsuite: Fix up lra effective target", we get for nvptx target:

    -PASS: gcc.c-torture/compile/asmgoto-2.c   -O0  (test for excess errors)
    +ERROR: gcc.c-torture/compile/asmgoto-2.c   -O0 : no files matched glob pattern "lra1020113.c.[0-9][0-9][0-9]r.reload" for " dg-do 2 compile { target lra } "

Etc.

However, nvptx appears to support 'asm goto' with outputs, including the
new execution test case:

    PASS: gcc.dg/pr107385.c execution test

Therefore, generally use new effective-target 'asm_goto_with_outputs' instead
of 'lra'.  One exceptions is 'gcc.dg/pr110079.c', which doesn't use 'asm goto'
with outputs, and continues using effective-target 'lra', with special-casing
nvptx target, to avoid ERROR for 'lra'.

README 

This directory contains the GNU Compiler Collection (GCC).

The GNU Compiler Collection is free software.  See the files whose
names start with COPYING for copying permission.  The manuals, and
some of the runtime libraries, are under different terms; see the
individual source files for details.

The directory INSTALL contains copies of the installation information
as HTML and plain text.  The source of this information is
gcc/doc/install.texi.  The installation information includes details
of what is included in the GCC sources and what files GCC installs.

See the file gcc/doc/gcc.texi (together with other files that it
includes) for usage and porting information.  An online readable
version of the manual is in the files gcc/doc/gcc.info*.

See http://gcc.gnu.org/bugs/ for how to report bugs usefully.

Copyright years on GCC source files may be listed using range
notation, e.g., 1987-2012, indicating that every year in the range,
inclusive, is a copyrightable year that could otherwise be listed
individually.
