99bd13b415 Hide debugging options 
llvm-svn: 2676
 2002-05-20 21:39:10 +00:00

2780d2dacb Numerous bug fixes: 
-- passing FP arguments to functions with more than 6 arguments
-- passing FP arguments to varargs functions
-- passing FP arguments to functions with no prototypes
-- incorrect coloring for CC registers (both int and FP): interferences
   were being completely ignored for int CC and were considered but no
   spills were marked for fp CC!

Also some code improvements:
-- better interface to generating machine instr for common cases
   (many places still need to be updated to use this interface)
-- annotations on MachineInstr to communicate information from
   one codegen phase to another (now used to pass information about
   CALL/JMPLCALL operands from selection to register allocation)
-- all sizes and offests in class TargetData are uint64_t instead of uint

to make debugging output a lot nicer.

c8e665431b * Rename MethodPass class to FunctionPass 
- Rename runOnMethod to runOnFunction
* Transform getAnalysisUsageInfo into getAnalysisUsage
  - Method is now const
  - It now takes one AnalysisUsage object to fill in instead of 3 vectors
    to fill in
  - Pass's now specify which other passes they _preserve_ not which ones
    they modify (be conservative!)
  - A pass can specify that it preserves all analyses (because it never
    modifies the underlying program)
* s/Method/Function/g in other random places as well

7a4b381f80 Don't record instructions for copying method arguments in the 
AddedInstrns sets for the first machine instruction.  It is hard
to ensure that the right order is preserved, and sure enough, the
order was broken.  Instead, use a separate set for the function entry.

pointer so that they do not all get leaked!

62b7fd136e Change references to the Method class to be references to the Function 
class.  The Method class is obsolete (renamed) and all references to it
are being converted over to Function.

aa2373d2ed Bug fix: address used by indirect call instruction should also 
be marked as having a Call Interference, even though it may not
be live after the call.

b0af9cdbda * Eliminate the LiveVarSet class, making applyTranferFuncForMInst a static 
function in the one .cpp file that uses it.  Use ValueSet's instead.
* Prepare to delete LiveVarSet.h & LiveVarSet.cpp
* Eliminate the ValueSet class, making all old member functions into global
  templates that will eventually be moved to Support.
* Eliminate some irrelevant const's

do not expose it.  Additionally, have it be auto generated by the pass framework
for us.

need to know _anything_ about RegAlloc to use it.  Well in the end maybe.

use the size of the register, not the size of the Value type,
to get the right alignment.
