libraries and headers exist. This can be specified using the platform select function: platform select --sysroot /Volumes/remote-root remote-macosx Each platform subclass is free to interpret the sysroot as needed. Expose the new SDK root directory through the SBDebugger class. Fixed an issue with the GDB remote protocol where unimplemented packets were not being handled correctly. llvm-svn: 133231
