Chris Lattner e42675f5af Get rid of 3 of the 4 'printimplicit' flags. Implicit operands are now 
explicitly listed in the asm string.

Chris Lattner 321763358b Specify an asm string and operands lists for a bunch of instructions. 
This only really covers no-operand instructions so far.

llvm-svn: 15387
 2004-08-01 06:01:00 +00:00
Chris Lattner 1c4ae85035 Initial cut at an asm writer emitter. So far, this only handles emission of 
instructions, and only instructions that take no operands at that!

llvm-svn: 15386
 2004-08-01 05:59:33 +00:00
Chris Lattner c860ecafe1 Add, and start using, the CodeGenInstruction class. This class represents 
an instance of the Instruction tablegen class.

Chris Lattner 70d2260eb9 Entirely eliminate all patterns and expanders from this file. We shall go 
with an incremental approach rather than a revolutionary approach.

llvm-svn: 15379
 2004-08-01 03:25:01 +00:00
Chris Lattner fc24e838a6 Move the 'Expander' node to later in the file, with the other experimental 
stuff.  The pattern becomes a list, add some stuff, add some comments.

Alkis Evlogimenos 62c979ba07 Make OptimizeBlock take a MachineFunction::iterator instead of a 
MachineBasicBlock* as a parameter so that nxext() and prior() helper
functions can work naturally on it.

 2004-07-31 15:14:29 +00:00
Alkis Evlogimenos 1e8d8fd81f Use MachineFunction::iterator instead of a MachineBasicBlock* because 
FallThrough maybe == to MF.end().

Chris Lattner 4504b95801 I'm pretty sure that ba is branch always, which is a barrier. Brg should 
check this :)
