Dale Johannesen 1a401e68a8 Arrange for only 1 of multiple branches to landing pad to be kept. 
Do not remove empty landing pads (EH table needs to be updated)

Chris Lattner 3e3ff30aa2 Fix the asmprinter so that a globalvalue can specify an explicit alignment 
smaller than the preferred alignment, but so that the target can actually
specify a minimum alignment if needed.  This fixes some objc protocol
failures Devang tracked down.

Lauro Ramos Venancio 5b0757a401 Fix PR1424. 
When a function has FP, the register scavenging spill slot offset already
was calculated.

 2007-05-30 00:32:01 +00:00
Dale Johannesen a69ebdbebc Make stable_sort in tail merging actually be stable (it never was, but didn't 
matter until my last change).  Reenable tail merging by default.

 2007-05-29 23:47:50 +00:00
Evan Cheng 20f7d30f92 Don't merge in tail block of a diamond if it has more than one predecessors after if-conversion.

 2007-05-29 23:36:32 +00:00
Evan Cheng 19eeee41ca For VFP2 fldm, fstm instructions, the condition code is printed after the address mode and size specifier. e.g. fstmiaseq, not fstmeqias.

Evan Cheng a6e9a4ce07 For ldrb, strh, etc., the condition code is before the width specifier. e.g. streqh, not strheq.

Owen Anderson 4a6ec8fb57 Use proper debugging facilities so other people don't have to look at my commented-out 
debugging lines.

llvm-svn: 37347
 2007-05-29 23:15:21 +00:00
Owen Anderson f11bdc7637 Comment debug code out that I accidentally uncommented last time. 
llvm-svn: 37346
 2007-05-29 22:43:03 +00:00
Owen Anderson ac83a3e4ff Add a place where I missed using the maximal set. Note that using the maximal 
set this way is _SLOW_.  Somewhere down the line, I'll look at speeding it up.

Evan Cheng c2237ce217 If there is an empty block between a source and its successor block, it still requires a unconditional branch.

 2007-05-29 22:31:16 +00:00
Owen Anderson 5fba6c19b2 Very first part of a GVN-PRE implementation. It currently performs a bunch of analysis, and nothing more. It is also quite slow for the moment. However, 
it should give a sense of what's going on.

class="doc_code">" to code examples.

llvm-svn: 37335
 2007-05-29 09:04:49 +00:00
Chris Lattner 8deaba7622 Add a new LLVMBuilder class, which makes it simpler and more uniform to 
create large amounts of instructions by separating the insertion point
logic from the logic of what to create.

llvm-svn: 37332
 2007-05-27 15:09:34 +00:00

Dale Johannesen 1409b6a59b Blocks that cond-br and uncond-br/fallthrough to same block should have 
only one successor.

llvm-svn: 37324
 2007-05-24 18:31:55 +00:00
Dale Johannesen 1af8c870c7 Fix for PR1444: do not create two successors to the same block. 
Temporarily, this breaks CodeGen/Generic/2006-02-12-InsertLibraryCall.ll
by exposing an unrelated latent problem; working on that.

llvm-svn: 37323
 2007-05-24 17:39:32 +00:00
