Chris Lattner 356f5a13f5 Dereferencing end() is bad. 
llvm-svn: 15402
 2004-08-01 09:51:42 +00:00

 2004-08-01 08:23:17 +00:00
Chris Lattner e42675f5af Get rid of 3 of the 4 'printimplicit' flags. Implicit operands are now 
explicitly listed in the asm string.

Chris Lattner d5540021fc The tblgen'erated asmparser wants a way to print operands.

 2004-08-01 07:43:46 +00:00
Chris Lattner 9520d20c83 Rename the Printer class -> X86AsmPrinter. 
Include the tablegenerated assembly writer.

 2004-08-01 06:01:32 +00:00
Chris Lattner 321763358b Specify an asm string and operands lists for a bunch of instructions. 
This only really covers no-operand instructions so far.

 2004-08-01 03:28:02 +00:00
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.

Chris Lattner 0f1c2ed907 Next on a pointer increments the pointer, not an iterator

 2004-07-31 18:40:36 +00:00
Alkis Evlogimenos 2303d3f660 Use next() helper to make code more readable. Use 
MachineFunction::iterator instead of MachineBasicBlock* to avoid
dereferencing end iterators.

llvm-svn: 15373
 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 :)

llvm-svn: 15357
 2004-07-31 02:24:37 +00:00
Chris Lattner 66a13e230d Mark barrier instructions. Execution does not fall through uncond branches 
or return intructions.

Brian Gaeke b10778dc07 Convert a few assertions with side-effects into regular old runtime checks. 
These side-effects seem to make a difference when using llc -march=sparcv9
in Release mode (i.e., with -DNDEBUG); when they are left out, lots of
instructions just get dropped on the floor, because they never end up
in the schedule.
