Dan Gohman 33a9cef204 The LLVM Assembly Language Reference incorrectly stated that the
prefix used for dll{import,export} is _imp__; it is actually __imp_.

Devang Patel 5daa1abf25 There is no need to maintain separate labelid list in the dwarf writer. It is not a good idea.

Rafael Espindola 6919ab4d05 Remove some dead code from the days llvm had type planes.
There might be more dead code, but with llvm-gcc bootstrap broken on linux x86-64 it is had to test :-(

Evan Cheng b2c42c648d Fix PR3241: Currently EmitCopyFromReg emits a copy from the physical register to a virtual register unless it requires an expensive cross class copy. That means we are only treating "expensive to copy" register dependency as physical register dependency.
Also future proof the scheduler to handle "normal" physical register dependencies. The code is not exercised yet.

Dale Johannesen f84685290a Increase default inlining aggressiveness in partial
compensation for turning off gcc's inliner.  This gets
us closer to the amount of inlining we were getting before.
It is not a win on everything, of course, but seems to
gain overall.

Gabor Greif 1b9921af34 simplify CallSite helper class to not consult the Instruction's
opcode on each delegation.
Instead the information is cached on construction and the cached flag used thereafter.
Introduced two predicates: isCall and isInvoke.

Chris Lattner bd3c7c8b52 Duncan is nervous about undefinedness of % with negatives. I'm
not thrilled about 64-bit % in general, so rewrite to use * instead.

Chris Lattner b19151686f do not generated GEPs into vectors where they don't already exist.
We should treat vectors as atomic types, not like arrays.

Chris Lattner 171d2d474f Make a couple of cleanups to the instcombine bitcast/gep
canonicalization transform based on duncan's comments:

1) improve the comment about %.
2) within our index loop make sure the offset stays 
   within the *type size*, instead of within the *abi size*.
   This allows us to reason explicitly about landing in tail
   padding and means that issues like non-zero offsets into
   [0 x foo] types don't occur anymore.

Chris Lattner f50aa6ae5c Implement rdar://6480391, extending of equality icmp's to avoid a truncation.
I noticed this in the code compiled for a routine using std::map, which produced
this code:
	%25 = tail call i32 @memcmp(i8* %24, i8* %23, i32 6) nounwind readonly
	%.lobit.i = lshr i32 %25, 31		; <i32> [#uses=1]
	%tmp.i = trunc i32 %.lobit.i to i8		; <i8> [#uses=1]
	%toBool = icmp eq i8 %tmp.i, 0		; <i1> [#uses=1]
	br i1 %toBool, label %bb3, label %bb4
which compiled to:

	call	L_memcmp$stub
	shrl	$31, %eax
	testb	%al, %al
	jne	LBB1_11	## 

with this change, we compile it to:

	call	L_memcmp$stub
	testl	%eax, %eax
	js	LBB1_11

This triggers all the time in common code, with patters like this:

	%169 = and i32 %ply, 1		; <i32> [#uses=1]
	%170 = trunc i32 %169 to i8		; <i8> [#uses=1]
	%toBool = icmp ne i8 %170, 0		; <i1> [#uses=1]

 	%7 = lshr i32 %6, 24		; <i32> [#uses=1]
	%9 = trunc i32 %7 to i8		; <i8> [#uses=1]
	%10 = icmp ne i8 %9, 0		; <i1> [#uses=1]

etc
