Hi Mark,
Hi Tim,
I think the top-level code you want is in (under clang) lib/Driver/ToolChains/Clang.cpp (a bunch of getTargetFeature stuff) and lib/Driver/ToolChains/CommonArgs.cpp (getCPUName especially). These defer to target-specific .cpp files in the more complete targets (lib/Driver/ToolChains/Arch/XYZ.cpp).
Spot on! Thank you!
I got it working now :-)
