[PATCH 04/15] MIPS/GAS/test: Correct handling of arch overrides

["Maciej W. Rozycki" <macro at linux-mips dot org>]

Hi,

 In the MIPS/GAS testsuite some targets such as the mipstx39-*-* create an 
additional "default" architecture.  This arrangement breaks architecture 
overrides, because in the case of this default architecture a name such 
as "default = r3900" will be used in place of the usual "r3900" as it 
would be in this case otherwise.  If this happens run_dump_test_arch will 
try the wrong override.

 The fix for this problem is to fetch the actual name of the architecture 
from its properties, that is a list whose first element is always the name 
of concern.  The fix follows.

2010-10-03  Maciej W. Rozycki  <macro@linux-mips.org>

	gas/testsuite/
	* gas/mips/mips.exp (run_dump_test_arch): Get the name of the
	architecture to check against for an architecture-specific test 
	from the properties instead of the name passed.

 OK to apply?

  Maciej
