Chad Rosier 425e951734 Fall back to the selection dag isel to select tail calls. ... This shouldn't affect codegen for -O0 compiles as tail call markers are not emitted in unoptimized compiles. Testing with the external/internal nightly test suite reveals no change in compile time performance. Testing with -O1, -O2 and -O3 with fast-isel enabled did not cause any compile-time or execution-time failures. All tests were performed on my x86 machine. I'll monitor our arm testers to ensure no regressions occur there. In an upcoming clang patch I will be marking the objc_autoreleaseReturnValue and objc_retainAutoreleaseReturnValue as tail calls unconditionally. While it's theoretically true that this is just an optimization, it's an optimization that we very much want to happen even at -O0, or else ARC applications become substantially harder to debug.
