Chris Lattner a65b4eac3b Revert patches 1.79 and 1.80 which had to do with dead MBB's. Now that they 
don't exist, we don't have to pretend to handle them.

Chris Lattner 55256dbf9b Fix potential problems with unreachable basic blocks. 
Also, while noone's looking, add support for constant expressions.  Wait,
I said not to look!

Chris Lattner 6c322ecc31 Remove dead blocks 
llvm-svn: 14564
 2004-07-02 05:46:41 +00:00
Chris Lattner 693244fb33 Add a trivially simple pass to delete unreachable blocks from the CFG. This 
pass is required to paper over problems in the code generator (primarily
live variables and its clients) which doesn't really have any well defined
semantics for unreachable code.

The proper solution to this problem is to have instruction selectors not
select blocks that are unreachable.  Until we have a instruction selection
framework available for use, however, we can't expect all instruction
selector writers to do this.  Until then, this pass should be used.

Brian Gaeke 186e3d1098 Add M_TERMINATOR_FLAG to terminator instructions (branches and returns). 
Also, the RETURN instructions are not used in the sparcv9 backend.

Brian Gaeke fb894bd864 RETURN instructions are not used in the sparc backend.

Misha Brukman 24a0371791 * Follow the PowerPC convention of leaving 24 bytes for linking on the stack. 
* Also leave space for spilling integer registers (this should be calculated)

Misha Brukman d028593c6e * Get rid of constant-expr handling code: we use the ConstantExpr lowering pass 
* Use the SetCC handling code in the format of Brian's V8
* Add FIXMEs where calls to functions are being made without adding them to the
  Module first... they cause missing symbols at assembly-time.
