Chris Lattner 3f3fb970e4 prune #includes, realize the MMI can never be null.

Chris Lattner 10cb0f4338 finally blast DwarfWriter away.

 2010-04-05 05:12:59 +00:00
Chris Lattner f0d6bd3ef4 change AsmPrinter to use DwarfDebug/DwarfException directly 
instead of going through DwarfWriter.

Johnny Chen dba13e7922 The disassembler impl. of MCDisassembler::getInstruction() was using the pattern 
uint32_t insn;
  MemoryObject.readBytes(Address, 4, (uint8_t*)&insn, NULL)

to read 4 bytes of memory contents into a 32-bit uint variable.  This leaves the
interpretation of byte order up to the host machine and causes PPC test cases of
arm-tests, neon-tests, and thumb-tests to fail.  Fixed to use a byte array for
reading the memory contents and shift the bytes into place for the 32-bit uint
variable in the ARM case and 16-bit halfword in the Thumb case.

Chris Lattner f0ef4e4019 implement EmitFunctionEntryLabel to emit the .cc_top directive, 
allowing xcore to use the normal runOnMachineFunction 
implementation.

Chris Lattner f5d0636850 trim some spurious references to DwarfWriter. SDIsel really doesn't 
need it anymore, so don't addRequire it.

Jakob Stoklund Olesen b93331f3be Replace TSFlagsFields and TSFlagsShifts with a simpler TSFlags field. 
When a target instruction wants to set target-specific flags, it should simply
set bits in the TSFlags bit vector defined in the Instruction TableGen class.

This works well because TableGen resolves member references late:

class I : Instruction {
  AddrMode AM = AddrModeNone;
  let TSFlags{3-0} = AM.Value;
}

let AM = AddrMode4 in
def ADD : I;

TSFlags gets the expected bits from AddrMode4 in this example.
