Chris Lattner e314bf5264 - Change getelementptr instruction to use long indexes instead of uint 
indexes for sequential types.

llvm-svn: 3683
 2002-09-11 01:21:35 +00:00
Vikram S. Adve d50fb11d18 Silly bug fix: Machine code vector could be empty for a no-op cast instruction, 
e.g., cast double to double.

Vikram S. Adve 7bc45123d3 -- Use size of pointer element type instead of pointer type in array offsets! 
-- A few bug fixes in casting between floats and ints.
-- Use SRL reg, 0 instead of AND reg, 0xffffffff to clear high 32 bits.

Chris Lattner b0b412e66e - Renamed Type::isIntegral() to Type::isInteger() 
- Added new method Type::isIntegral() that is the same as isInteger, but
    also accepts bool.

 2002-09-03 01:08:28 +00:00
Vikram S. Adve 541862fbf3 Sign-extend values used to index arrays (and Simplify 
SetOperandsForMemInstr significantly).  Load and Store
no longer have any indices.  Eliminate spurious sign-extension
on a cast to float/double.

llvm-svn: 3498
 2002-08-24 20:56:53 +00:00
Chris Lattner 02fe752fbd Eliminated the MemAccessInst class, folding contents into GEP class. 
llvm-svn: 3488
 2002-08-22 23:37:24 +00:00
Vikram S. Adve 2d85a9976a Eliminate bool, boolreg and boolconst nonterminals, and just use 
reg and Constant instead.

llvm-svn: 3441
 2002-08-22 02:56:10 +00:00
Vikram S. Adve caed269085 Revise code generation for unary Not (boolean and bitwise), which is 
no longer a separate instruction but is instead implemented with XOR.

llvm-svn: 3342
 2002-08-15 14:17:37 +00:00
Vikram S. Adve 3a5a29faf4 Handle small unsigned results correctly by clearing high bits.

llvm-svn: 3278
 2002-08-09 20:08:06 +00:00
Vikram S. Adve b4a9685872 Bug fix in SetOperandsForMemInstr: handle leading zeros correctly 
when folding or not folding GEPs.

llvm-svn: 3245
 2002-08-04 20:51:05 +00:00
Chris Lattner b430c3f395 Fix compilation problem. IsIndexZero doesn't exist, use IsZero instead. 
llvm-svn: 3243
 2002-08-03 20:57:38 +00:00
Vikram S. Adve 1944064801 Simplified handling of array indexes in SetMemOperands_Internal. 
llvm-svn: 3236
 2002-08-03 13:48:21 +00:00
Vikram S. Adve defe6ec939 Add a missing case: converting float/double to unsigned integer types. 
llvm-svn: 3188
 2002-07-31 21:01:34 +00:00
Chris Lattner e98dd5fcac *** empty log message *** 
llvm-svn: 3056
 2002-07-24 21:21:32 +00:00
Vikram S. Adve 82190d3e73 Have to save a boolean (setCC) value whenever use is outside the current 
basic block.

Mark setCCInstr used as dest. of conditional-move as both a def and a use.

BA instruction no longer has the unused CC argument.

Vikram S. Adve e9327f0082 Numerous bug fixes: 
-- correct sign extensions for integer casts and for shift-by-constant
   instructions generated for integer multiply
-- passing FP arguments to functions with more than 6 arguments
-- passing FP arguments to varargs functions
-- passing FP arguments to functions with no prototypes
-- incorrect stack frame size when padding a section
-- folding getelementptr operations with mixed array and struct indexes
-- use uint64_t instead of uint for constant offsets in mem operands
-- incorrect coloring for CC registers (both int and FP): interferences
   were being completely ignored for int CC and were considered but no
   spills were marked for fp CC!

Also some code improvements:
-- better interface to generating machine instr for common cases
   (many places still need to be updated to use this interface)
-- annotations on MachineInstr to communicate information from
   one codegen phase to another (now used to pass information about
   CALL/JMPLCALL operands from selection to register allocation)
-- all sizes and offests in class TargetData are uint64_t instead of uint

llvm-svn: 2323
 2002-04-27 02:25:14 +00:00
Vikram S. Adve dccabec1ea Insert copy operations for FP arguments to a varargs function, 
to copy the FP arg. to an integer.  Necessary so that the
register allocator has two different live ranges for the FP value
and the int. argument.

llvm-svn: 2314
 2002-04-25 04:37:51 +00:00
Chris Lattner f8a9bfbc03 Move the InsertPrologEpilogCode class out of the Sparc.cpp file into the 
new PrologEpilogCodeInserter.cpp file, and include the bodies of the
GetInstructionsFor(Prolog|Epilog) functions from SparcInstrSelection.cpp
into the class.  This eliminates the need for a static global vector of
instructions and a class of errors that is really unneccesary.

Chris Lattner 62b7fd136e Change references to the Method class to be references to the Function 
class.  The Method class is obsolete (renamed) and all references to it
are being converted over to Function.

llvm-svn: 1964
 2002-03-24 03:33:02 +00:00

Also, use distinct names for the three types of SetMachineOperand to
avoid painful overloading problems and errors.
Bug fix in converting-int-to-float.  Other minor stuff.
