New Revision: 271543
URL: http://llvm.org/viewvc/llvm-project?rev=271543&view=rev
Log:
Fixed a problem where -gmodules debug info would be loaded by the DWO file
support accidentally and cause 1000s of files to be mapped into LLDB's address
space for each .o file that reference a module.
<rdar://problem/26580266> -gmodules causes LLDB.framework to map hundreds of
copies of the same .pcm file
