Michael Gottesman [Sat, 12 Jan 2013 01:25:15 +0000 (01:25 +0000)]
Fixed a bug where we were tail calling objc_autorelease causing an object to not be placed into an autorelease pool.

The reason that this occurs is that tail calling objc_autorelease eventually
tail calls -[NSObject autorelease] which supports fast autorelease. This can
cause us to violate the semantic gaurantees of __autoreleasing variables that
assignment to an __autoreleasing variables always yields an object that is
placed into the innermost autorelease pool.

The fix included in this patch works by:

1. In the peephole optimization function OptimizeIndividualFunctions, always
remove tail call from objc_autorelease.
2. Whenever we convert to/from an objc_autorelease, set/unset the tail call
keyword as appropriate.

*NOTE* I also handled the case where objc_autorelease is converted in
OptimizeReturns to an autoreleaseRV which still violates the ARC semantics. I
will be removing that in a later patch and I wanted to make sure that the tree
is in a consistent state vis-a-vis ARC always.

Additionally some test cases are provided and all tests that have tail call marked
objc_autorelease keywords have been modified so that tail call has been removed.

*NOTE* One test fails due to a separate bug that I am going to commit soon. Thus
I marked the check line TMP: instead of CHECK: so make check does not fail.

This patch tackles the problem of parsing Mips
register names in the standalone assembler llvm-mc.

Registers such as $A1 can represent either a 32 or

In addition, based on the abi, $T0 can represent different

The MCAsmParser interface defines ParseIdentifier is public. There's no reason

This is all part of a bigger scheme. Several asm parsing "extensions" use the

GenericAsmParser has much more exclusive access and uses implementation details

a friend. This makes for overly coupled code, and even makes it hard to split
GenericAsmParser into a separate file. There's no reason why GenericAsmParser
shouldn't be able to access AsmParser through an abstract interface, as long
as it's actually registered as an extension.

Stack Alignment: throw error if we can't satisfy the minimal alignment
requirement when creating stack objects in MachineFrameInfo.

Add CreateStackObjectWithMinAlign to throw error when the minimal alignment
can't be achieved and to clamp the alignment when the preferred alignment
can't be achieved. Same is true for CreateVariableSizedObject.
Will not emit error in CreateSpillStackObject or CreateStackObject.

As long as callers of CreateStackObject do not assume the object will be
aligned at the requested alignment, we should not have miscompile since
later optimizations which look at the object's alignment will have the correct
information.
