Owen Anderson 47db941fd3 Get rid of the Pass+Context magic. 
llvm-svn: 76702
 2009-07-22 00:24:57 +00:00
Owen Anderson 1e5f00e7a7 This started as a small change, I swear. Unfortunately, lots of things call the [I|F]CmpInst constructors. Who knew!?

Dan Gohman 8918b481bf More minor code simplifications.

Dan Gohman ac3b5382b8 Change this code to a form about which VC++ reportedly isn't unhappy.

Devang Patel bab43b4c91 Do not count DbgInfoIntrinsic while estimating loop header size.

Duncan Sands 5a913d61e3 Rename getAnalysisToUpdate to getAnalysisIfAvailable.

Chris Lattner 7b6647c178 Fix PR3408 by making a non-obvious assumption very obvious, and 
handling the flaw inherent in that assumption.  :)

Chris Lattner 57cb472b56 More cleanups and simplifications, no functionality change. 
llvm-svn: 62983

Chris Lattner d67aaa6560 tidy asserts

Daniel Dunbar 7f39e2d85a Change create*Pass factory functions to return Pass* instead of 
LoopPass*.
 - Although less precise, this means they can be used in clients
   without RTTI (who would otherwise need to include LoopPass.h, which
   eventually includes things using dynamic_cast). This was the
   simplest solution that presented itself, but I am happy to use a
   better one if available.

Dan Gohman a79db30d28 Tidy up several unbeseeming casts from pointer to intptr_t. 
llvm-svn: 55779
 2008-09-04 17:05:41 +00:00
Dan Gohman fa1211f69b Enable first-class aggregates support. 
Remove the GetResultInst instruction. It is still accepted in LLVM assembly
and bitcode, where it is now auto-upgraded to ExtractValueInst. Also, remove
support for return instructions with multiple values. These are auto-upgraded
to use InsertValueInst instructions.

The IRBuilder still accepts multiple-value returns, and auto-upgrades them
to InsertValueInst instructions.

Dan Gohman 9eea470fcf Avoid using BasicBlock::getInstList directly in a few places. 
llvm-svn: 52497
 2008-06-19 17:37:25 +00:00
Dan Gohman f96e1371e8 Tidy up BasicBlock::getFirstNonPHI, and change a bunch of places to 
use it instead of duplicating its functionality.

llvm-svn: 51499
 2008-05-23 21:05:58 +00:00
Gabor Greif 697e94cc22 Fix a bunch of 80col violations that arose from the Create API change. Tweak makefile targets to find these better. 
llvm-svn: 51143
 2008-05-15 10:04:30 +00:00
Dan Gohman d78c400b5b Clean up the use of static and anonymous namespaces. This turned up 
several things that were neither in an anonymous namespace nor static
but not intended to be global.

 2008-05-13 00:00:25 +00:00
Chris Lattner a700b2bd0f add a FIXME so we remember to eventually remove this code.

Dale Johannesen 78ffe6e939 Don't try to create PHIs of struct types. Fallout 
from x86-64 calling convention work.

Owen Anderson 7629b71dd4 Revert r49614. As Dan pointed out, some of these aren't correct. 
llvm-svn: 49657
 2008-04-14 17:38:21 +00:00
Owen Anderson 1f6fbc4bc3 Replace calls of the form V1->setName(V2->getName()) with V1->takeName(V2), 
which is significantly more efficient.

llvm-svn: 49614
 2008-04-13 19:15:17 +00:00
Gabor Greif e9ecc68d8f API changes for class Use size reduction, wave 1. 
Specifically, introduction of XXX::Create methods
for Users that have a potentially variable number of
Uses.

Owen Anderson b0dd27ee91 Make LoopInfoBase more generic, in preparation for having MachineLoopInfo. This involves a small interface change. 
llvm-svn: 44348

Devang Patel fac4d1f014 Preserve analysis info. 
llvm-svn: 39767
 2007-07-11 23:47:28 +00:00
Nick Lewycky 9b2252c6f0 Back out Devang's fix for PR1320 because it causes PR1542. 
llvm-svn: 37966

Devang Patel 8c78a0bff0 Drop 'const' 
llvm-svn: 36662
 2007-05-03 01:11:54 +00:00
Devang Patel e95c6ad802 Use 'static const char' instead of 'static const int'. 
Due to darwin gcc bug, one version of darwin linker coalesces
static const int, which defauts PassID based pass identification.

llvm-svn: 36652
 2007-05-02 21:39:20 +00:00
Devang Patel 09f162ca6a Do not use typeinfo to identify pass in pass manager.

Devang Patel bca0d57179 Check _all_ PHINodes. 
llvm-svn: 35836
 2007-04-09 22:20:10 +00:00
Devang Patel 8eb8eeada9 Insert new pre-header before new header. Original pre-header may 
happen to be an entry, in such case, it is not a good idea to
insert new block before entry.

Also fix typo in assertion check.

llvm-svn: 35833

Devang Patel 854197884b Preserve canonical loop form.

Handle Argument or Undef as an incoming PHI value.
