Chris Lattner e09bbc800c Add a helper method 
llvm-svn: 22768
 2005-08-12 22:14:06 +00:00
Chris Lattner 1749aaa5e6 Fix an iterator invalidation problem when we decide a phi has a constant value 
llvm-svn: 22675
 2005-08-05 15:34:10 +00:00
Chris Lattner 6f58350daf Now that hasConstantValue is more careful w.r.t. returning values that only 
dominate the PHI node, this code can go away.  This also makes passes more
aggressive, e.g. implementing Transforms/CondProp/phisimplify2.ll

llvm-svn: 22670
 2005-08-05 01:02:04 +00:00
Nate Begeman b392321cae Fix a fixme in CondPropagate.cpp by moving a PhiNode optimization into 
BasicBlock's removePredecessor routine.  This requires shuffling around
the definition and implementation of hasContantValue from Utils.h,cpp into
Instructions.h,cpp

Chris Lattner cdb9bfc150 remove all of the various setName implementations, consolidating them into 
Value::setName, which is no longer virtual.

llvm-svn: 20289
 2005-02-23 16:53:04 +00:00
Chris Lattner cf08c21f2c Reduce the amount of searching this assertion does. On a testcase of mine, 
this reduces the time for -simplifycfg in a debug build from 106s to 14.82s

Chris Lattner 8d0b1b2a82 Check in the file I forgot last night, to solve all of the crashes in every

llvm-svn: 15327
 2004-07-29 16:53:53 +00:00
Chris Lattner bea7247357 Find bugs sooner rather than later. In this case, don't allow the creation 
of instructions that don't have a first-class or void type.

llvm-svn: 14646

Chris Lattner 08d1b9db1e Fix GCC warnings 
llvm-svn: 14044
 2004-06-05 17:43:52 +00:00
Chris Lattner 708ee9d965 As much as I dislike doing this, it's the only fix for VC8.0 that I can come 
up with, even though it's perfectly conformant code.  :(

 2004-02-04 03:57:50 +00:00
Chris Lattner 9cda4bf8e5 When splitting a basic block, insert the new half immediately after the first 
half.

llvm-svn: 11110
 2004-02-04 03:21:31 +00:00
Chris Lattner c4c7ea5288 In BasicBlock::splitBasicBlock, just use islist::splice to move the instructions, 
instead of a loop that is really inefficient with large basic blocks.

This speeds up the inliner pass on the testcase in PR209 from 13.8s to 2.24s
which still isn't exactly speedy, but is a lot better.  :)

 2003-04-23 16:37:45 +00:00
Chris Lattner 98cf1f5d64 - Eliminated the deferred symbol table stuff in Module & Function, it really

Chris Lattner 4dfede8070 - Add new ctor to BasicBlock to allow insertion before any BB, not just at 
the end of the function.

llvm-svn: 3934
