[PATCH 1/4] GAS: Permit the reuse of dump patterns


 This is a change to add support for the "dump" option to run_dump_test().  
This lets one specify an alternative .d file providing regexp patterns for 
the test output to match against, typically another .d file that differs 
by the options used only.  Options for the current test are retrieved from 
${file}.d as usually, which is also the default when no "dump" has been 
specified.  This is useful in multi-arch testing, saving the need to keep 
an exact copy of the patterns used for each subarchitecture and to update 
all of them whenever anything changes.

2010-07-20  Maciej W. Rozycki  <>

	* lib/gas-defs.exp (run_dump_test): Handle the "dump" option.

 OK to apply?
