e6ba8a819c 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.

d414793dbc 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.

4b783303e5 Jimptables working again on alpha. 
As a bonus, use the GOT node instead of the AlphaISD::GOT for internal stuff.

d5f5a433b2 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().

4f41b86e7f 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

11590ccf0c Use $( $| $) to represent alternatives in asm blocks instead of {|}. This 
is needed to support targets where {|} aren't special symbols.

ddf92db1ca 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.

the number of relocations in object files, shrinkifying them.

557d3cacbe 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

65c5f1b9e0 On 64-bit targets like ppc64, we should use .quad to output pointer directives, 
not .long.

6ec6e10b48 Add support to print 4-, 8-, and 16- byte constant literals in special

0dc7ed966c Was pointed out that structure alignment and type alignment are not the same 
thing.  Doubles still need to be special cased.

to get the alignment of the element type.

TargetData.h.  This should make recompiles a bit faster with my current
