Chris Lattner e3c374ac33 Use the RHS length instead of the LHS length. They are both the same, 
but this ends up compiling code like this:

int foo(const StringRef &R) {
  return R == "food";
}

to use a constant sized memcmp instead of a variable memcmp.

Nick Lewycky ec7ec7c1ac Move MSILModule and MSILWriter into the 'llvm' namespace, instead of the 'MSIL' 
namespace which could very well conflict with non-LLVM code.

Also clean up some spacing, remove an extra header.

 2009-07-26 05:55:20 +00:00
Chris Lattner 1d68bd7f97 Rearrange all the SectionKinds and structure them into a hierarchical 
group instead of a bunch of random unrelated ideas.  Provide predicates
to categorize a SectionKind into a group, and use them instead of 
getKind() throughout the code.

This also renames a ton of SectionKinds to be more consistent and
evocative, and adds a huge number of comments on the enums so that
I will hopefully be able to remember how this stuff works long from
now.

Daniel Dunbar 19e7076ddd Update Triple to use StringRef/Twine based APIs. 
- This is now shorter, simpler, safer, and more efficient, what a deal.

Daniel Dunbar 4f7dfaf650 Update for API change. 
llvm-svn: 77112
 2009-07-26 02:21:04 +00:00
Daniel Dunbar 47d679151b Add TargetRegistry::lookupTarget. 
- This is a simplified mechanism which just looks up a target based on the
   target triple, with a few additional flags.

 - Remove getClosestStaticTargetForModule, the moral equivalent is now:
     lookupTarget(Mod->getTargetTriple, true, false, ...);

 - This no longer does the fuzzy matching with target data (based on endianness
   and pointer width) that getClosestStaticTargetForModule was doing, but this
   was deemed unnecessary.

Chris Lattner 397792d981 finish simplifying DarwinTargetAsmInfo::SelectSectionForGlobal 
for now.  Make the section switching directives more consistent

Daniel Dunbar 3c27648eda Some clients rely on getName{Start,End} not returning 0, even if the length is 
0.
 - I could have swore the prev change went through a make check cycle...

 2009-07-26 01:04:10 +00:00
Daniel Dunbar 32285942a1 Rewrite getName{Start,End,Len} in terms of getName(), instead of vice-versa.

 2009-07-26 00:51:56 +00:00
Chris Lattner 5b42b45fb9 simplify DarwinTargetAsmInfo::SelectSectionForGlobal a bit 
and make it more aggressive, we now put:

const int G2 __attribute__((weak)) = 42;

into the text (readonly) segment like gcc, previously we put
it into the data (readwrite) segment.
