Chris Lattner b022bed018 Expose proto for SRoA pass. 
llvm-svn: 6348
 2003-05-27 15:52:45 +00:00
Vikram S. Adve 11fc2f6885 (1) Added special register class containing (for now) %fsr. 
Fixed spilling of %fcc[0-3] which are part of %fsr.

(2) Moved some machine-independent reg-class code to class TargetRegInfo
    from SparcReg{Class,}Info.

 2003-05-27 00:07:13 +00:00
Vikram S. Adve 6bbfe341dd Renamed MachienOperand::opIsDef to MachineOperand::opIsDefOnly() 
and related functions and flags.  Fixed several bugs where only
"isDef" was being checked, not "isDefAndUse".

like all the other functions.

Misha Brukman e2402c65d0 Reword to remove reference to how things worked in the past. 
llvm-svn: 6323
 2003-05-24 01:08:43 +00:00
Misha Brukman 23d15a71b8 NOP instructions are pseudo-instructions. We should not have them explicitly in 
our representation, since they are usually special cases of already-existing
instructions.

This abstracts away methods that let a pass create and verify a NOP instruction,
without relying on a `NOP' enum to be in existence in the target's instruction
info descriptor.

llvm-svn: 6108
 2003-05-12 03:51:30 +00:00
Chris Lattner b78244f9e1 Make sure that globals are emitted AFTER the passmanager is set up for the JIT, 
because the globals may refer to functions that need to be compiled!

llvm-svn: 6003
 2003-05-06 18:45:02 +00:00
Misha Brukman f4c7d206a3 It's 'separate'. The 'i.e.' is kinda nit-picking, but think of it this way: 
'separate' is the one causing you to recompile all your passes anyway.

Chris Lattner 7606fb65c0 This is a substantial rewrite of the AliasSetTracker class which now uses 
a union-find based algorithm, is significantly faster, and is more general.
It will also scale to handle call instructions correctly, which is a nice
added bonus.

This includes a new pass -print-alias-sets which can be used to show how
alias sets are formed for a particular analysis.
