Vikram S. Adve 75b4a29613 Bug fix in folding getElementPtr instructions: don't fold one into 
a predecessor if it has a non-zero first index and the predecessor
ends with a struct index.

Vikram S. Adve 5b5dd671b2 Minor change to interface for Create{Zero,Sign}ExtensionsInstructions. 
llvm-svn: 3979
 2002-09-29 21:53:31 +00:00
Chris Lattner 6443769b34 Hoist the contents of Loops in depth first order in the dominator tree, 
rather than in random order.  This causes LICM to be DRAMATICALLY more
effective. For example, on bzip2.c, it is able to hoist 302 loads and
2380 total instructions, as opposed to 44/338 before.  This  obviously
makes other transformations much more powerful as well!

Vikram S. Adve 9011903ee2 Added a couple of helper methods for live range construction. 
llvm-svn: 3970
 2002-09-28 17:05:43 +00:00
Vikram S. Adve ed2df3ecf8 Live ranges for Return value and return address of a Call are now 
created here, simply by handling all implicit operands (which should
have been done anyway).

llvm-svn: 3969
 2002-09-28 17:05:22 +00:00
Vikram S. Adve 8076fe87b7 Fixed method getReturnValue(): it should return NULL if the 
callee does not return a value.

llvm-svn: 3968
 2002-09-28 17:03:54 +00:00
Vikram S. Adve 8fef3b8033 Fixed incorrect assertion: spill code for function ptr should be 
handled like normal operands, not like other call arguments.

llvm-svn: 3967
 2002-09-28 17:02:40 +00:00
Vikram S. Adve d76d82b40f Return address register should be marked as "result" for the JMPL instruction 
since it is defined by the instruction.

llvm-svn: 3966
 2002-09-28 17:00:15 +00:00
Vikram S. Adve 6d1036d41b Live ranges for Return value and return address of a Call are no longer 
created here.  Instead they are created in LiveRangeInfo.cpp.  This
simplifies the code here quite a bit.

llvm-svn: 3965
 2002-09-28 16:59:05 +00:00
Vikram S. Adve cce628aeaf Simplified code that handles call args and rets, so it no longer 
needs the RegClass list to be passed in.

llvm-svn: 3964
 2002-09-28 16:56:59 +00:00
Vikram S. Adve 4bb9866dc5 Simplify Call translation slightly.

 2002-09-28 16:51:47 +00:00
Vikram S. Adve 34d16d64b0 Overhaul integer conversions to match C++ ISO standard. 
Don't allow direct FP-to-uint conversion (must be eliminated by preselection).
Address arithmetic for arrays is now entirely 64-bit so no sign-ext needed.

llvm-svn: 3961
 2002-09-27 14:33:08 +00:00
Vikram S. Adve 40e2347b90 Modify operand order for Create{Sign,Zero}ExtensionInstructions.

Chris Lattner 647df647e1 First try at implementing the AliasSetTracker class. I'm sure it will need 
revision as I start to use it though.

Chris Lattner ed06af34b6 * Run preheaders pass tests 
* Linearize list of directories so I don't have to keep dealing with
  wrapping problems.

llvm-svn: 3953

Chris Lattner b009ceaa9d Checkin the simple features tests for the preheader insertion pass. 
llvm-svn: 3952
 2002-09-26 19:50:11 +00:00
Chris Lattner d57f3f5073 - Further cleanups of LICM pass, remove extra work from previous implementation 
- Do not clone instructions then insert clone outside of loop.  Just move them.

Chris Lattner d771fdfd75 Loop invariant code motion now depends on the LoopPreheader pass. Dead code 
has not yet been removed.

llvm-svn: 3945
 2002-09-26 16:19:31 +00:00
Chris Lattner bedbd6bc16 - Cleanup break-crit-edges pass by making SplitCriticalEdge a member method. 
- break-crit-edges pass does not invalidate loop-preheader pass.
