On x86 favors folding short immediate into some arithmetic operations (e.g. add, and, xor, etc.) because materializing an immediate in a register is expensive in turns of code size.
e.g.
movl 4(%esp), %eax
addl $4, %eax

is 2 bytes shorter than

movl $4, %eax
addl 4(%esp), %eax

Support block pointer conversions in C++. I'm storing the test case locally until we can enable blocks in C++

  - a table including the IdentifierInfo data
  - an index from persistent IdentifierInfo IDs to indices within this file.
- Enhance PTH generation to write out file map information, mapping inodes to tokens.

converting a pointer to one Objective-C interface into a pointer to another
Objective-C interface, and conversions with 'id'. The semantics seems
to match GCC, although they seem somewhat ad hoc.

Fixed a few cases where we assumed the C++ definition of isObjectType,
but were getting the C definition, causing failures in trouble with
conversions to void pointers.

the conditional for the BRCOND statement. For instance, it will generate:

    addl %eax, %ecx
    jo LOF

instead of

    addl %eax, %ecx
    ; About 10 instructions to compare the signs of LHS, RHS, and sum.
    jl LOF

performance in most cases on the Grawp tester, but does speed some 
things up (like shootout/hash by 15%).  This also doesn't impact 
compile time in a noticable way on the Grawp tester.

It also, of course, gets the testcase it was designed for right :)

-Change Parser::ParseCXXScopeSpecifier to MaybeParseCXXScopeSpecifier
-Remove Parser::isTokenCXXScopeSpecifier and fold it into MaybeParseCXXScopeSpecifier
-Rename Parser::TryAnnotateScopeToken to TryAnnotateCXXScopeToken and only allow it to be called when in C++

Implemented anonymous category (also know as continuation class)
used to override main class's property attribute. This is work in
