Vikram S. Adve 31dbda2a1c Add a test for folding a GEP into a load. 
llvm-svn: 4139
 2002-10-13 00:44:00 +00:00
Vikram S. Adve 9e5eb46362 Use vectors instead of hash_maps for issueGaps and conflictLists. 
These hash lookups were a major sink of time because they happen so often!
Also, add option to disable scheduling.

Vikram S. Adve f8c6e3db55 Major bug fix: was not adding CD edges for RETURNs!

Vikram S. Adve 05ee0819a7 Run LICM before GCSE! 
llvm-svn: 4135
 2002-10-13 00:34:10 +00:00
Vikram S. Adve 10d8164013 Several major fixes, particularly in emitting constant aggregates: 
(1) Padding bytes between structure fields (for alignment) were never
    being emitted into the constant pool so the layout did not match!
(2) In printing constants, structures containing structures or arrays
    were never handled.
(3) Support new model for external/uninitialized/initialized globals.
    Uninitialized globals are no longer emitted since they are external.
    Initialized globals may go either in .bss or in .data.

Vikram S. Adve 78044fbc8e Don't use %l0 for large operands to a SAVE since it is needed *before* SAVE! 
We now use %g1 instead since that is shared and volatile.

llvm-svn: 4133
 2002-10-13 00:24:06 +00:00
Vikram S. Adve f4f7292b4e Don't mark JMPLCALL and JMPLRET as branches.

Nick Hildenbrandt 176245f782 *** empty log message *** 
llvm-svn: 4131
 2002-10-13 00:20:48 +00:00
Vikram S. Adve d2dc60e5d9 (1) Try to evaluate constant when multiplying 2 constants. 
(2) Use intelligent multiply selection code for array allocas.
(3) Don't use cache padding for alloca'd stack slots!
(4) Bug fix in handling call arguments: was not copying sixth FP arg
    to int reg. when calling a function with no prototype.

Vikram S. Adve d00beecb59 Eliminate duplicate target pointer in SparcRegInfo. 
llvm-svn: 4129
 2002-10-13 00:06:04 +00:00
Vikram S. Adve 879eac9fa1 Eliminate duplicate target pointer. Also add a few assertions. 
llvm-svn: 4128
 2002-10-13 00:05:30 +00:00
Vikram S. Adve ea31dc707f Make sure to handle small negative values hiding as large unsigned longs -- 
this is a common case created by the front-end.

llvm-svn: 4127
 2002-10-13 00:04:26 +00:00
Vikram S. Adve 4ef6cce821 Major fix: extract ConstantExpr nodes and decompose them into symbolic 
instructions so that (a) constant folding is done automatically before
code generation, and (b) selection does not have to deal with them.
Also, check for ConstantPointerRefs in additional to GlobalValues
when creating a GEP to load a global address.

llvm-svn: 4126
 2002-10-13 00:01:57 +00:00
Vikram S. Adve 46f21c4443 Added inline constant expressions, including uses in binary subtract.

Chris Lattner 66507d887a * Fix extract to work with constant pointer refs correctly 
* Extract makes all global vars external, so they don't have initializers

Nick Hildenbrandt fa6e71e31d Instead of adding stdlib we just prototype malloc correctly. 
llvm-svn: 4118
 2002-10-11 21:40:44 +00:00
Nick Hildenbrandt 8d354423fc Sun requires you to include stdlib to use malloc

Vikram S. Adve 3e54d6c3be Major bug fix: spill code for an instruction in a delay slot was 
merrily being inserted before/after the instruction!

Vikram S. Adve ffc9dd5c0d Don't pad variables in stack slots for performance!

Misha Brukman 33022f07bb Added capability to get execution count of a loop if it is a predictable 
number of iterations.

llvm-svn: 4113

Misha Brukman 3845be203d Added helper functions in LoopInfo: isLoopExit and numBackEdges.

* use new api to get all nodes in the graph
  * Allow custom graph traits

Chris Lattner eac4dcd0bd - Dramatically simplify the ConstantMerge code now that 
Value::replaceAllUsesWith works with constants correctly.

llvm-svn: 4104
 2002-10-09 23:16:04 +00:00
Chris Lattner 2c6abeac43 - Make Value::replaceAllUsesWith work with constants correctly. This fixes 
bug FuncResolve/2002-08-19-ResolveGlobalVars.ll and gzip looks better.

llvm-svn: 4103
 2002-10-09 23:12:59 +00:00
Chris Lattner b1dd9bbc68 - Add new Constant::replaceUsesOfWithOnConstant which has an end result 
similar to User::replaceUsesOfWith but actually does the right thing for
    constants.

llvm-svn: 4102
 2002-10-09 23:12:25 +00:00
Chris Lattner 083a1f7890 Make isExtern() be a virtual function inherited from GlobalValue

 2002-10-09 21:49:44 +00:00
Chris Lattner 013eca003a Almost a complete rewrite of FunctionResolution to now resolve functions 
and global variables.

This fixes bug: FuncResolve/2002-08-19-ResolveGlobalVarsEasier.ll
And bug: SingleSource/UnitTests/2002-10-09-ArrayResolution.c

Note that this does not fix bug:
FunctionResolve/2002-08-19-ResolveGlobalVars.ll because replaceAllUsesWith
breaks when a constantexpr is pointing to the thing being replaced.  This
is more of an infrastructure problem than anything.

Chris Lattner 3d6c35b92e - Detemplatize UseTy<> in Value.h, because it's only instantiated for one 
type!

llvm-svn: 4093
 2002-10-09 00:42:03 +00:00
