Chris Lattner a70c7dff2e Validate that the input to 'Pat' patterns is sane.

Chris Lattner 2a230e1c1a teach tblgen to be smart enough to handle tglobaladdr nodes 
llvm-svn: 24391
 2005-11-17 07:39:45 +00:00
Chris Lattner 595088aa0f Add an initial hack at legalizing GlobalAddress into the appropriate nodes 
on Darwin to remove smarts from the isel.  This is currently disabled by
default (uncomment setOperationAction(ISD::GlobalAddress to enable it).
tblgen needs to become smarter about tglobaladdr nodes and bigger patterns
needed to be added to the .td file.  However, we can currently emit stuff like
this:  :)

        li r2, lo16(L_x$non_lazy_ptr)
        lis r3, ha16(L_x$non_lazy_ptr)
        lwzx r2, r3, r2

The obvious improvements will follow.

Chris Lattner 840458276c Add globaladdress and targetglobaladdress nodes for dag patterns

Chris Lattner 63ed749ce0 LI could theoretically be used for the lo-part of a global address, just like 
lis can be used for the high part.

Chris Lattner b7025749e1 When lowering direct calls, lower them to use a targetglobaladress directly 
instead of a globaladdress.  This has no effect on the generated code at all.

Chris Lattner b22950df6c fix a tblgen bug that Evan ran into, where we would lose the '$src' name 
on patterns like "(set R32:$dst, (i32 imm:$src))"

Chris Lattner 6b41edb30f * Fix DerivedType::dropAllTypeUses to not change the number of types in a 
type when it gets refined.  This allows us to hash on this crucial value.
* Fix several issues in TypeMap::RefineAbstractType that prevent it from
  handling hash values that change correctly.
* Define hashTypeStructure to not always return 0.  :)

This last part (which depends on the first two) speeds up gccld time on eon
from 3.78s to 2.75s with a release build (a 28% speedup!).  This resolves
PR474.
