312ef27b52 If the user did not check out LLVM and request it to be built, it should be a build error. This relies on the user having a successful build of LLVM, but the tests will fail if they dont.

bd4b11cfa9 Initial support for multi-result patterns: 
1.
[(set GR32:$dst, (add GR32:$src1, GR32:$src2)),
 (modify EFLAGS)]
This indicates the source pattern expects the instruction would produce 2 values. The first is the result of the addition. The second is an implicit definition in register EFLAGS.
2.
def : Pat<(parallel (addc GR32:$src1, GR32:$src2), (modify EFLAGS)), ()>
Similar to #1 except this is used for def : Pat patterns.

67d3119773 This resolves a regression of BasicAA which failed to find any memory information for overloaded intrinsics (PR1600). This resolves that issue, and improves the matching scheme to use a BitVector rather than a binary search.

00e56b0e81 This is the patch to provide clean intrinsic function overloading support in LLVM. It cleans up the intrinsic definitions and generally smooths the process for more complicated intrinsic writing. It will be used by the upcoming atomic intrinsics as well as vector and float intrinsics in the future. 
This also changes the syntax for llvm.bswap, llvm.part.set, llvm.part.select, and llvm.ct* intrinsics. They are automatically upgraded by both the LLVM ASM reader and the bitcode reader. The test cases have been updated, with special tests added to ensure the automatic upgrading is supported.

4a3a018844 VStudio compiler errors and placing Function*->ExFunc map under ManagedStatic control. 
This commit fixes two things.  One is a pair of VStudio compiler errors stemming from variables
which defined within the for loop statement and also within the body of the for loop.  I fixed these 
by renaming one of the two variables.  Additionally, I've made the Function*->ExFunc map in 
ExternalFunctions.cpp a ManagedStatic object, so that cleanup will be done on llvm_shutdown.  In repeated
uses of the interpreter, where the same Function* address may get used for completely differnet functions,
this was causing a crash.

8312ed6f77 Change instruction description to split OperandList into OutOperandList and 
InOperandList. This gives one piece of important information: # of results
produced by an instruction.
An example of the change:
def ADD32rr  : I<0x01, MRMDestReg, (ops GR32:$dst, GR32:$src1, GR32:$src2),
                 "add{l} {$src2, $dst|$dst, $src2}",
                 [(set GR32:$dst, (add GR32:$src1, GR32:$src2))]>;
=>
def ADD32rr  : I<0x01, MRMDestReg, (outs GR32:$dst), (ins GR32:$src1, GR32:$src2),
                 "add{l} {$src2, $dst|$dst, $src2}",
                 [(set GR32:$dst, (add GR32:$src1, GR32:$src2))]>;

9cbc3fb1ab Revert the earlier change that removed the M_REMATERIALIZABLE machine 
instruction flag, and use the flag along with a virtual member function
hook for targets to override if there are instructions that are only
trivially rematerializable with specific operands (i.e. constant pool
loads).
