New Revision: 373563
URL: http://llvm.org/viewvc/llvm-project?rev=373563&view=rev
Log:
SBDebugger::SetInputFile, SetOutputFile, etc.
Summary:
Add new methods to SBDebugger to set IO files as SBFiles instead of
as FILE* streams.
In future commits, the FILE* methods will be deprecated and these
will become the primary way to set the debugger I/O streams.
