Reid Spencer 542964f55b Rename BoolTy as Int1Ty. Patch by Sheng Zhou. 
llvm-svn: 33076
 2007-01-11 18:21:29 +00:00
Zhou Sheng 75b871fb1e For PR1043: 
Merge ConstantIntegral and ConstantBool into ConstantInt.
Remove ConstantIntegral and ConstantBool from LLVM.

Reid Spencer e63b6518fa For PR950: 
Three changes:
1. Convert signed integer types to signless versions.
2. Implement the @sext and @zext parameter attributes. Previously the
   type of an function parameter was used to determine whether it should
   be sign extended or zero extended before the call. This information is
   now communicated via the function type's parameter attributes.
3. The interface to LowerCallTo had to be changed in order to accommodate
   the parameter attribute information. Although it would have been
   convenient to pass in the FunctionType itself, there isn't always one
   present in the caller. Consequently, a signedness indication for the
   result type and for each parameter was provided for in the interface
   to this method. All implementations were changed to make the adjustment
   necessary.

Reid Spencer 4e0c2a0e41 Just print integer constants as signed values. The actual signedness 
doesn't matter as it is determined in the way the constant is used.

Jim Laskey 70323a8146 1. Tidy up jump table info. 
2. Allow the jit to handle PIC relocable jump tables.

Chris Lattner 0c537dae55 split up inttoptr from ptrtoint handling, the cases aren't similar at all.

Chris Lattner b9e41f5559 the operand of a bitcast is always the right size, just emit it in place.

Bill Wendling f3baad3ee1 Changed llvm_ostream et all to OStream. llvm_cerr, llvm_cout, llvm_null, are 
now cerr, cout, and NullStream resp.

Bill Wendling 5c3966aa68 Converted to using llvm streams instead of <iostream>s 
llvm-svn: 31992
 2006-11-29 00:39:47 +00:00
Reid Spencer 6c38f0bb07 For PR950: 
The long awaited CAST patch. This introduces 12 new instructions into LLVM
to replace the cast instruction. Corresponding changes throughout LLVM are
provided. This passes llvm-test, llvm/test, and SPEC CPUINT2000 with the
exception of 175.vpr which fails only on a slight floating point output
difference.

Anton Korobeynikov aa4c0f9374 1. Clean up code due to changes in SwitchTo*Section(2) 
2. Added partial debug support for mingw\cygwin targets (the same as
   Linux\ELF). Please note, that currently mingw\cygwin uses 'stabs' format
   for storing debug info by default, thus many (runtime) libraries has
   this information included. These formats shouldn't be mixed in one binary
   ('stabs' & 'DWARF'), otherwise binutils tools will be confused.

Reid Spencer e0fc4dfc22 For PR950: 
This patch implements the first increment for the Signless Types feature.
All changes pertain to removing the ConstantSInt and ConstantUInt classes
in favor of just using ConstantInt.

Andrew Lenharth a6bbf33cbf Jimptables working again on alpha. 
As a bonus, use the GOT node instead of the AlphaISD::GOT for internal stuff.

llvm-svn: 30873
 2006-10-11 04:29:42 +00:00
Chris Lattner 9043823cf4 If a target uses a GOT, put it in the jt data section, not the text 
section.  This will fix alpha when Andrew implements
AlphaTargetMachine::getTargetLowering().

Chris Lattner 66c1625a37 Emit pic jumptables to the same section that the function is emitted to, 
allowing label differences to work.  This fixes CodeGen/X86/pic_jumptable.ll

Chris Lattner fc416faaa0 Use $( $| $) to represent alternatives in asm blocks instead of {|}. This 
is needed to support targets where {|} aren't special symbols.

Chris Lattner 30b4708df2 Add support for ${:private} which prints "L" on darwin. 
llvm-svn: 30620
 2006-09-27 00:06:07 +00:00
Chris Lattner a32814b033 Add support for ${:comment}, which expands to the current target's comment 
character, and ${:uid} which expands to a unique ID for the MachineInstr.
More can be added if/when they are needed.

llvm-svn: 30619
 2006-09-26 23:59:50 +00:00
Chris Lattner 66af390631 Add support for targets that want to do something with the llvm.used list, 
because they have an aggressive linker that does dead code stripping.

llvm-svn: 30604

llvm-svn: 30326
 2006-09-14 07:35:00 +00:00
Evan Cheng 45fe3bc72c Added support for machine specific constantpool values. These are useful for 
representing expressions that can only be resolved at link time, etc.

Nate Begeman 984c1a4a8f Emit .set directives for jump table entries when possible, which reduces 
the number of relocations in object files, shrinkifying them.

llvm-svn: 29650
 2006-08-12 21:29:52 +00:00
Chris Lattner 85492427f2 Instead of blindly looking past constantexpr casts, actually constant 
fold them.  This correctly truncates constants that are too large for the
destination slot and makes the code easier to understand.  This fixes PR853
and Regression/CodeGen/X86/2006-07-28-AsmPrint-Long-As-Pointer.ll

llvm-svn: 29408
 2006-07-29 01:57:19 +00:00

Chris Lattner fd5a8ebb74 On 64-bit targets like ppc64, we should use .quad to output pointer directives, 
not .long.

llvm-svn: 29157
 2006-07-15 01:34:12 +00:00
Evan Cheng ec1d60bd98 Add support to print 4-, 8-, and 16- byte constant literals in special 
sections. e.g. On Darwin that would be .literal4 and .literal8.

llvm-svn: 28977
 2006-06-29 00:26:09 +00:00
Jim Laskey 3519b87758 Was pointed out that structure alignment and type alignment are not the same 
thing.  Doubles still need to be special cased.
