Chris Lattner 497d13e82b emit the __builtin -> intrinsic map with StringMatcher instead of a 
copy of a close relative of it.

Chris Lattner 6dcaa42540 same bug, another place.

Chris Lattner 9bb3bf1b59 fix a critical bug where the generated table would say 
"1 strings to match" in a comment, which isn't gramatic.

Rafael Espindola b2d0d40c3d Make "-ccc-cxx" option work on Linux. 
Patch by nobled.

I also took the opportunity to make the field private since now it is only ready from the
outside.

Chris Lattner ca5a3554b5 factor the snazzy string matcher code that Daniel hates 
out of AsmMatcherEmitter.cpp into its own class.

Chris Lattner fb43da66b5 slightly improve the runtime and code size of the Intrinsics info table by not 
comparing the "llvm." prefix in the memcmp, and not storing it in the string literal.

Chris Lattner b01c24a945 Teach loop rotate to hoist trivially invariant instructions 
in the duplicated block instead of duplicating them.  

Duplicating them into the end of the loop and the preheader 
means that we got a phi node in the header of the loop, 
which prevented LICM from hoisting them.  GVN would
usually come around later and merge the duplicated 
instructions so we'd get reasonable output... except that
anything dependent on the shoulda-been-hoisted value can't
be hoisted.  In PR5319 (which this fixes), a memory value
didn't get promoted.

Chris Lattner da24b9a49a pull a simple method out of LICM into a new 
Loop::hasLoopInvariantOperands method. Remove
a useless and confusing Loop::isLoopInvariant(Instruction)
method, which didn't do what you thought it did.

No functionality change.

Eli Friedman 0b1fbd1394 PR7242: Make sure to use a different context for evaluating constant 
initializers, so the result of the evaluation doesn't leak through
inconsistently.  Also, don't evaluate references to variables with
initializers with side-effects.

Chris Lattner f43cb302ca remove some dead code. t2addrmode_imm8s4 is never used in a 
pattern, so there is no need to define a matching function.

Nick Lewycky 0095937b13 Fix many bugs when merging weak-strong and weak-weak pairs. We now merge all 
strong functions first to make sure they're the canonical definitions and then
do a second pass looking only for weak functions.

Chris Lattner eeba0c73e5 implement rdar://6653118 - fastisel should fold loads where possible. 
Since mem2reg isn't run at -O0, we get a ton of reloads from the stack,
for example, before, this code:

int foo(int x, int y, int z) {
  return x+y+z;
}

used to compile into:

_foo:                                   ## @foo
	subq	$12, %rsp
	movl	%edi, 8(%rsp)
	movl	%esi, 4(%rsp)
	movl	%edx, (%rsp)
	movl	8(%rsp), %edx
	movl	4(%rsp), %esi
	addl	%edx, %esi
	movl	(%rsp), %edx
	addl	%esi, %edx
	movl	%edx, %eax
	addq	$12, %rsp
	ret

Now we produce:

_foo:                                   ## @foo
	subq	$12, %rsp
	movl	%edi, 8(%rsp)
	movl	%esi, 4(%rsp)
	movl	%edx, (%rsp)
	movl	8(%rsp), %edx
	addl	4(%rsp), %edx    ## Folded load
	addl	(%rsp), %edx     ## Folded load
	movl	%edx, %eax
	addq	$12, %rsp
	ret

Fewer instructions and less register use = faster compiles.
