Daniel Dunbar d9eff3d4e4 Lift out ABIInfo abstract base class. 
- Currently still lives in CGCall.cpp but is intended to be the
   target specific place for hooking ABI information.
 - Select ABIInfo to use based on Target's prefix and pointer width.

constant expression with all zero indices as being the same as a bitcast.

Matthijs Kooijman 0e2682781c Improve the description on the getelementptr instruction. It should now better 
define what the instruction does. This also makes it clear that getelementptr
can index into a vector type.

Matthijs Kooijman 43686a6665 * Make TargetLowering not crash when TargetMachine::getTargetAsmInfo() returns 
null. This assumes that any target that does not have AsmInfo, does not
   support "LocAndDot".

Nick Lewycky 707663eda8 Disallow the construction of SCEVs with could-not-compute operands. Catch CNCs 
returned by BinomialCoefficient and don't try to operate with them. This
replaces the previous fix for PR2857.

 2008-10-12 18:30:33 +00:00
Argyrios Kyrtzidis 3768ad6d58 Implement more efficient Decl <-> DeclContext conversions. 
When the static type on the Decl side is a subclass of DeclContext the compiler will use a "inlinable" static_cast, instead of always using an out-of-line function call.

Note, though, that the isa<> check still uses an out-of-line function call.

Dale Johannesen ba074c0fed Change Dwarf comments starting with AT_ to DW_AT_ to 
match gcc.  Helps with the testsuite.

llvm-svn: 57410
 2008-10-12 06:20:47 +00:00
Chris Lattner f6a3bda65e make the -rewrite-test a bit more interesting: it now 
wraps comments in <i> tags.  Extend rewrite tokens to support
this minimal functionality.

llvm-svn: 57409
 2008-10-12 06:09:52 +00:00

 2008-10-12 06:03:38 +00:00
Chris Lattner b6aa53b7de start implementing a token rewriter. At this point, it just reads in a file 
and lets a client iterate over it. 

llvm-svn: 57407
 2008-10-12 05:44:03 +00:00
Chris Lattner 1782da2f84 Add a new -rewrite-test option, which is basically a 
playground to experiment with some new rewriter approaches. For now
it is probably the most complex version of 'cat' ever invented.

llvm-svn: 57406
 2008-10-12 05:29:20 +00:00
Chris Lattner fc7d4a3bd2 Add a new -dump-raw-tokens option, which allows us to see raw tokens. 
Rename -dumptokens to -dump-tokens.

llvm-svn: 57405
 2008-10-12 05:03:36 +00:00
Chris Lattner b11c3233d8 Change FormTokenWithChars to take the token kind to form, since all clients 
were setting a kind and then forming it.  This is just a minor API cleanup, 
no functionality change.

llvm-svn: 57404
 2008-10-12 04:51:35 +00:00
Chris Lattner 99e7d23455 When in keep whitespace mode, make sure to return block comments that are 
unterminated.

llvm-svn: 57403
 2008-10-12 04:19:49 +00:00
Chris Lattner e01e758e11 Change SkipBlockComment and SkipBCPLComment to return true when in 
keep comment mode, instead of returning false.  This matches SkipWhitespace.

llvm-svn: 57402
 2008-10-12 04:15:42 +00:00
Chris Lattner 4d96344c19 Add a new mode to the lexer which enables it to return all characters, 
even whitespace, as tokens from the file.  This is enabled with
L->SetKeepWhitespaceMode(true) on a raw lexer.  In this mode, you too
can use clang as a really complex version of 'cat' with code like this:

  Lexer RawLex(SourceLocation::getFileLoc(SM.getMainFileID(), 0),
               PP.getLangOptions(), File.first, File.second);
  
  RawLex.SetKeepWhitespaceMode(true);
  
  Token RawTok;
  RawLex.LexFromRawLexer(RawTok);
  while (RawTok.isNot(tok::eof)) {
    std::cout << PP.getSpelling(RawTok);
    RawLex.LexFromRawLexer(RawTok);
  }

This will emit exactly the input file, with no canonicalization or other
translation.  Realistic clients actually do something with the tokens of
course :)
