gdb/testsuite/compiler.c[c]: Identify clang

gdb/testsuite/compiler.c[c]: Identify clang

[David Blaikie]

[-- Attachment #1: Type: text/plain, Size: 503 bytes --]

Adding support for the testsuite to correctly identify the clang
compiler (previously it caught the generic GCC detection and was
identified as GCC 4.2).

This reduces some of the test failures when running the suite with
Clang - for example the macro tests no longer run or fail (since
they're only enabled for GCC).

    * compiler.c: identify the clang compiler

(do I need a separate ChangeLog line for compiler.cc too? should the
ChangeLog entry have the full path (gdb/testsuite/lib/compiler.c)?)

Hi.

Here's a changelog entry to use for this particular case.
The format has lots of precise rules behind it, but Monkey-See-Monkey-Do hacking should get you most if not all of the way there.

2014-04-07  David Blaikie  <dblaikie@gmail.com>

	* lib/compiler.c: Identify the clang compiler.
	* lib/compiler.cc: Ditto.

In general, all edited files need to be mentioned (though there is debate over this for some cases, wheee....), and path names are required to be relative to the directory in which the ChangeLog lives.
There is a convention for how to submit a changelog entry involving multiple ChangeLog files, but there's no need to go into that here.

Thanks

Oh, and I realized I didn't actually specify, but I don't have commit
access to gdb so if the patch (and suggested ChangeLog) are acceptable
it'd be great if someone could commit it for me.

Thanks!

Done.
