Chris Lattner 9c9b4c54fa No functional changes, comment the fix I just put in

Chris Lattner 01349f463c The CodeEmitterGenerator used to consider ANY uninitialized field as being an 
operand (unless it's annul or predict).  Now we only consider fields to be
operands if they are uninitialized AND used in the "Inst" field.

Chris Lattner 506fa6843e Revert previous change, and be really anal about what physical registers can do.

 2003-08-05 00:49:09 +00:00
Chris Lattner 7c257321c7 This is the real fix for the previous register allocator problem. 
Physical registers should not float around.

Misha Brukman f7586ceeb2 Reformatted code to match the prevalent LLVM style; fit code into 80 columns.

Chris Lattner 4b637cc666 Don't bother calculating info unless its needed. May reduce number of stack slots created.

Chris Lattner 148747e162 Add patterns for (mov R, R) (mov R, I) and subtracts. The moves are to enable 
testing, the subtracts are because I was in the neighborhood.

Chris Lattner 7d0adf79ec * Don't print out HOW we are running Flex unless in verbose mode. We already 
hide the bison command line.
* If running flex or bison gives us the files we already have, don't overwrite
  the ones we have, which cause unnecessary compilation.  I demand the ability
  to make meaningless changes without penalty!

Misha Brukman 4aad821408 Do not attempt to reduce a test case if it is an empty set.

 2003-08-04 19:03:42 +00:00
John Criswell fe69bc502d Added code that ensures that we don't try to reduce an empty vector of basic 
blocks.
This fixes the bugpoint regressions.

Chris Lattner 5dcb654662 * Sort #includes, remove dupliates 
* Use .zero to emit padding between struct elements
* Emit .comm symbols when we can, this dramatically reduces the amount of gunk we have to print
* Print global variable identifiers next to initializer more nicely.

Chris Lattner 05e2f385a7 * Start using tablegen'd instruction descriptions 
* Fix bug in the createNOP method, which was not marking the operands of the
  generated XCHG as useanddef.  I don't think this method is actually used,
  so it wasn't breaking anything, but it should be fixed anyway...
