Hi Michael,


2003-12-02 Alexandre Oliva <aoliva@redhat.com>

* config/tc-sh.c: Add support for sh4a and no-fpu variants.
* testsuite/gas/sh/basic.exp: Call tests for sh4a.
* testsuite/gas/sh/{err-sh4a-fp.s, err-sh4a.s, err-sh4al-dsp.s, sh4a-dsp.d, sh4a-dsp.s, sh4a-fp.d, sh4a-fp.s, sh4a.d, sh4a.s, sh4al-dsp.d, sh4al-dsp.s:
New files, tests for sh4a and related variants.


Approved - but before applying please could you or Alex fix up the
problem pointed out by Andrew Stubbs (namly that the new command line
switches are not documented in the -help output) and the fact that
these options are not documented in the gas/doc/c-sh64.texi file.

One other thing - please could you add an entry to the gas/NEWS file
mentioning the new support.

OK, committed with the following amendments:


2003-12-02  Alexandre Oliva  <aoliva@redhat.com>

	* config/tc-sh.c: Add support for sh4a and no-fpu variants,
	with appropriate additions to md_show_usage.
	* testsuite/gas/sh/basic.exp: Call tests for sh4a.
	* testsuite/gas/sh/{err-sh4a-fp.s, err-sh4a.s, 
	err-sh4al-dsp.s, sh4a-dsp.d, sh4a-dsp.s, sh4a-fp.d, 
	sh4a-fp.s, sh4a.d, sh4a.s, sh4al-dsp.d, sh4al-dsp.s:
	New files, tests for sh4a and related variants.
	* doc/c-sh.texi: Document new -isa options.
	* doc/c-sh64.texi: Ditto.
	* NEWS: Mention new support for sh4a.
