I gave this patch a spin on a mac. The only failure I got was in test/Shell/SymbolFile/DWARF/TestDedupWarnings.test, which fails it does not generate both of the warnings, and that's because the "p" (aka dwim-print) now resolves to "frame var" instead of expr". Changing the test to use "expr a/b" instead should fix it.
