New Revision: 176613

URL: http://llvm.org/viewvc/llvm-project?rev=176613&view=rev
Log:
Added new properties to lldb.SBModule classes:

"compile_units" returns an array of all compile units in a module as a list() of lldb.SBCompileUnit objects.

"compile_unit" returns a compile unit accessor object that allows indexed access, search by full or partial path, or by regex:

(lldb) script
comp_unit = lldb.target.module['TextEdit'].compile_unit['Document.m']
comp_unit = lldb.target.module['TextEdit'].compile_unit['/path/to/Document.m']
comp_unit = lldb.target.module['TextEdit'].compile_unit[0]
comp_unit = lldb.target.module['TextEdit'].compile_unit[1]
for comp_unit in lldb.target.module['TextEdit'].compile_unit[re.compile("\.m$")]
  print comp_unit

This helps do quick searches and scripting while debugging.
