Chris Lattner d14b0f1db7 improve switch formation to handle small range 
comparisons formed by comparisons.  For example,
this:

void foo(unsigned x) {
  if (x == 0 || x == 1 || x == 3 || x == 4 || x == 6) 
    bar();
}

compiles into:

_foo:                                   ## @foo
## BB#0:                                ## %entry
	cmpl	$6, %edi
	ja	LBB0_2
## BB#1:                                ## %entry
	movl	%edi, %eax
	movl	$91, %ecx
	btq	%rax, %rcx
	jb	LBB0_3

instead of:

_foo:                                   ## @foo
## BB#0:                                ## %entry
	cmpl	$2, %edi
	jb	LBB0_4
## BB#1:                                ## %switch.early.test
	cmpl	$6, %edi
	ja	LBB0_3
## BB#2:                                ## %switch.early.test
	movl	%edi, %eax
	movl	$88, %ecx
	btq	%rax, %rcx
	jb	LBB0_4

This catches a bunch of cases in GCC, which look like this:

 %804 = load i32* @which_alternative, align 4, !tbaa !0
 %805 = icmp ult i32 %804, 2
 %806 = icmp eq i32 %804, 3
 %or.cond121 = or i1 %805, %806
 %807 = icmp eq i32 %804, 4
 %or.cond124 = or i1 %or.cond121, %807
 br i1 %or.cond124, label %.thread, label %808

turning this into a range comparison.

Daniel Dunbar e054a782fc MC/ARM: Use aggressive symbol folding (important for jump tables, for example). 
llvm-svn: 122044
 2010-12-17 06:00:24 +00:00
Daniel Dunbar 137d422e50 MC/Expr: Implemnt more aggressive folding during symbol evaluation using 
IsSymbolRefDifferenceFullyResolved(). For example, we will now fold away
something like:
--
_a:
...
L0:
...
L1:
...
.long (L1 - L0) / 2
--

Daniel Dunbar 2ee6c9b8c9 MC/Mach-O: On second thought, use a custom hook for enabling aggressive 
IsSymbolRefDifferenceFullyResolved, it turns out this does change behavior on
enough cases for x86-32 that I would rather wait a bit on it.
 - In practice, we will want to change this eventually because it only means we
   generate less relocations (it also eliminates the need for the horrible
   '.set' hack that Darwin requires in some places).

Ted Kremenek 853da96736 Move CocoaConventions.[h,cpp] from libChecker 
to libAnalysis.  Similar to Format (format string checking), 
CocoaConventions has the
potential to serve clients other than the
static analyzer.

Daniel Dunbar b27bb86ba5 MC/Mach-O: Implement IsSymbolRefDifferenceFullyResolved. 
- Unlike for fixups, we always do the "reliable" thing (not just for x86_64).
 - Since Darwin 'as' would typically reject things that using this will allow,
   we don't need to worry about compatibility.

Daniel Dunbar f2adf782ab MC/ObjectWriter: Add a new IsSymbolRefDifferenceFullyResolved target format specific hook.

Jakob Stoklund Olesen 9c7f3a46d8 Provide LiveIntervalUnion::Query::checkLoopInterference. 
This is a three-way interval list intersection between a virtual register, a
live interval union, and a loop. It will be used to identify interference-free
loops for live range splitting.

Greg Clayton f028a1fb84 Added access to set the current stack frame within a thread so any command 
line commands can use the current thread/frame.

Fixed an issue with expressions that get sandboxed in an objective C method
where unichar wasn't being passed down.

Added a "static size_t Scalar::GetMaxByteSize();" function in case we need
to know the max supported by size of something within a Scalar object.

Dan Gohman 93dc2b808f Revert r64460. strtol and friends cannot be marked readonly, even with 
a null endptr argument, because they may write to errno.

was enabled.
