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.

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

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.

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.

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.

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

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

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.

Jim Laskey 3519b87758 Was pointed out that structure alignment and type alignment are not the same
thing.  Doubles still need to be special cased.

Jim Laskey dce07568f2 Alignment of globals has not been quite right. Needed to drop the pointer type
to get the alignment of the element type.

Owen Anderson 8c2c1e90c4 Refactor a bunch of includes so that TargetMachine.h doesn't have to include
TargetData.h.  This should make recompiles a bit faster with my current

Chris Lattner d36cc2b610 Don't prefix section directives with a tab. Doing so causes blank lines to

Owen Anderson 20a631fde7 Refactor TargetMachine, pushing handling of TargetData into the target-specific subclasses. This has one caller-visible change: getTargetData() now returns a pointer instead of a reference.
This fixes PR 759.
