Fix a bug in SILValue's hoistAddressProjections #7

aschwaighofer · 2015-11-20T16:07:53Z

We have to insert instructions that are operands before the instruction using
them as an operand.

Also fix a bug in the same code when looking through single predecessor basic
block arguments.

Add a testcase for all three cases.

Remove line directives from generated files.

typelayout_based_value_witness.swift failed on iphoneos-arm64e due to an extra line of IR that gets generated. That meant the swift_release line had 'swiftlang#7' instead of 'swiftlang#6'. The test shouldn't be checking for 'swiftlang#6' anyways, so removed that check which causes the test to now pass.

Fixes: Assertion failed: (isa<To>(Val) && "cast<Ty>() argument of incompatible type!"), function cast, file Casting.h While running pass swiftlang#224 SILFunctionTransform "LifetimeDependenceDiagnostics" swiftlang#7 0x0000000102d3efcc decltype(auto) llvm::cast<swift::DebugValueInst, swift::SILInstruction>(swift::SILInstruction*) swiftlang#8 0x0000000102d01e24 swift::DebugValueInst* BridgedInstruction::getAs<swift::DebugValueInst>() const swiftlang#9 0x0000000102d01ee4 BridgedInstruction::GlobalAddr_getDecl() const

This inserts a suitably named function into the stack trace whenever a dynamic cast failure involves a NULL source or target type. Very often, crash logs include backtraces with function names but no log output; with this change, such a backtrace might look like the following -- note `TARGET_TYPE_NULL` in the function name here to mark the missing type information: ``` frame #0: __pthread_kill + 8 frame swiftlang#1: pthread_kill + 288 frame swiftlang#2: abort + 128 frame swiftlang#3: swift::fatalErrorv() frame swiftlang#4: swift::fatalError() frame swiftlang#5: swift_dynamicCastFailure_TARGET_TYPE_NULL() frame swiftlang#6: swift::swift_dynamicCastFailure() frame swiftlang#7: ::swift_dynamicCast() ``` Resolves rdar://130630157
