73ee5ff6b8 (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.

ab50c0aee5 Renamed MachienOperand::opIsDef to MachineOperand::opIsDefOnly() 
and related functions and flags.  Fixed several bugs where only
"isDef" was being checked, not "isDefAndUse".

3b22d1b247 Do not show errors when moving file. The error is shown the first time anyone 
runs `utils/cvsupdate' since there is no `cvs.out' file for mv to move, and it
is reported as such.

b7a0d570a8 Implement the TargetInstrInfo's createNOPinstr() and isNOPinstr() interface. 
llvm-svn: 6320
 2003-05-24 00:09:50 +00:00
Misha Brukman
151f7484ab 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.

b599881570 gccld.cpp: 
Fix typo in header.
 Add IsArchive static method.
 Roll LoadLibraryFromDirectory() into LoadLibrary(), and factor
  LoadLibraryExactName() out of the result. Instead of treating the current
  directory specially, just insert it into LibPaths in the beginning of
  main().
 Make LoadLibrary() take a "search" flag that says whether to search for the
  correct library, or just trust that LibName is right.
 Make LinkLibrary() take a "search" flag, and pass it to LoadLibrary().
 Change the for-loop over InputFilenames to detect ar archives and link them
  in as libraries without searching.
 Change the for-loop over Libraries to explicitly turn on the "search" flag
  to LinkLibrary() that makes LoadLibrary() search for the correct library
  (i.e., when processing -lNAME options.)

500984b918 Fix Bug: Linker/2003-04-26-NullPtrLinkProblem.ll 
This was a problem with constants having their types resolved to some new type,
but there was already a constant of the new type created.  Before, these types
were never merged together, now they are.
