*	Some comments.	Evan Cheng	2007-01-31	1	-2/+6
\| \| \| \|	llvm-svn: 33707
*	ConstPool island bug: watch out for cases where UserMI is the last MI of the BB.	Evan Cheng	2007-01-31	1	-4/+16
\| \| \| \|	llvm-svn: 33706
*	- Added Thumb constpool island support.	Evan Cheng	2007-01-31	1	-24/+17
\| \| \| \| \| \| \|	- Islands are inserted right after the user MI since thumb LDR cannot encode negative offset. llvm-svn: 33690
*	- In thumb mode, if size of MachineFunction is >= 2048, force LR to be	Evan Cheng	2007-01-30	1	-31/+99
\| \| \| \| \| \| \| \| \| \| \| \| \|	spilled (if it is not already). - If LR is spilled, use BL to implement far jumps. LR is not used as a GPR in thumb mode so it can be clobbered if it is properly spilled / restored in prologue / epilogue. - If LR is force spilled but no far jump has been emitted, try undo'ing the spill by: push lr -> delete pop pc -> bx lr llvm-svn: 33650
*	Factor GetInstSize() out of constpool island pass.	Evan Cheng	2007-01-29	1	-69/+4

*	Conditional branch being fixed up is not the last MI in the BB, there is a	Evan Cheng	2007-01-26	1	-13/+51
\| \| \| \| \| \| \| \| \| \| \| \| \|	unconditional branch following it. Simply invert the condition and swap destinations if the conditional branch can reach the destination of the unconditional branch: beq L1 b L2 => bne L2 b L1 llvm-svn: 33548
*	Make LABEL a builtin opcode.	Jim Laskey	2007-01-26	1	-0/+2

*	SplitBlockBeforeInstr() insert a unconditional branch to the next BB. This	Evan Cheng	2007-01-26	1	-2/+6
\| \| \| \| \| \| \|	is unnecessary when we are fixing up a conditional branch since we will be adding a unconditional branch to the destination of the original branch. llvm-svn: 33517
*	Need to scan the function for branches even if there aren't any constants.	Evan Cheng	2007-01-26	1	-3/+2
\| \| \| \|	llvm-svn: 33515
*	Forgot to update this.	Evan Cheng	2007-01-25	1	-1/+1
\| \| \| \|	llvm-svn: 33512
*	Add comment, fix typo, reduce memory usage, etc.	Evan Cheng	2007-01-25	1	-9/+14
\| \| \| \|	llvm-svn: 33510
*	Doh. Skip JT branches.	Evan Cheng	2007-01-25	1	-1/+2
\| \| \| \|	llvm-svn: 33501
*	Added (preliminary) branch shortening capability to constantpool island pass.	Evan Cheng	2007-01-25	1	-7/+130
\| \| \| \|	llvm-svn: 33497
*	Use PC relative ldr to load from a constantpool in Thumb mode.	Evan Cheng	2007-01-24	1	-0/+3
