port to properly use L for the bb prefix instead of .

llvm-svn: 24450
 2005-11-21 07:30:28 +00:00
Chris Lattner 2bccd73dbb Start using SwitchSection, allowing globals and functions to be emitted 
to specific sections.  Delete some dead functions copied from the X86 backend.

 2005-11-21 06:51:52 +00:00
Chris Lattner 41cb115afb set PrivateGlobalPrefix on darwin, use it when printing out CP references 
llvm-svn: 24441
 2005-11-21 06:47:58 +00:00
Chris Lattner 618981fd03 Naturally align doubles in the constant pool, set PrivateGlobalPrefix on 
darwin, use it when printing the constant pool indices so the labels are
appropriately private, emit cp entries to .const instead of .data on darwin
and only emit a single .section for the constant pool, not one for each
entry.

Nate Begeman b2e089c31b Teach LLVM how to scalarize packed types. Currently, this only works on 
packed types with an element count of 1, although more generic support is
coming.  This allows LLVM to turn the following code:

void %foo(<1 x float> * %a) {
entry:
  %tmp1 = load <1 x float> * %a;
  %tmp2 = add <1 x float> %tmp1, %tmp1
  store <1 x float> %tmp2, <1 x float> *%a
  ret void
}

Into:

_foo:
        lfs f0, 0(r3)
        fadds f0, f0, f0
        stfs f0, 0(r3)
        blr
