Anders Carlsson e70cde134e Handle the 'X' constraint. Fixes <rdar://problem/6504897>.

 2009-01-18 02:12:04 +00:00
Chris Lattner 137d6492a8 switch PTHLexer to use Read32 and friends instead of lots of inlined 
copies.  I verified that this causes no performance change in PTH.

 2009-01-18 02:01:21 +00:00
Chris Lattner eb09754a9d switch PTH lexer from using "const char*"s to "const unsigned char*"s 
internally.  This is just a cleanup that reduces the need to cast to
unsigned char before assembling a larger integer.

Chris Lattner 71dc14b9f0 Rename SourceLocation::getFileID to getChunkID, because it returns 
the chunk ID not the file ID.  This exposes problems in 
TextDiagnosticPrinter where it should have been using the canonical
file ID but wasn't.  Fix these along the way.

Chris Lattner 5509d533f6 simplify some lookups. 
llvm-svn: 62426
 2009-01-17 08:30:10 +00:00
Chris Lattner 757169b60f Change the Lexer ctor used to lex _Pragma directives into a static factory 
method.  This lets us clean up the interface and make it more obvious that
this method is *really really* _Pragma specific.

Note that _Pragma handling uglifies the Lexer in the critical path.  It would
be very interesting to consider making _Pragma remapping be a new special
lexer class of its own.

Chris Lattner c809089b26 Change the Lexer ctor used in the non _Pragma case to take a FileID instead 
of a SourceLocation.  This should speed it up and definitely simplifies it.

Chris Lattner 8ddb5cf0cf in Preprocessor::AdvanceToTokenCharacter, don't actually bother 
creating a whole lexer when we just want one static method.

embedded magic.

entire file.

Chris Lattner 3793bba26f suck the call to "getSpellingLoc" that all clients do into 
the implementation of PTHManager::getSpelling.

llvm-svn: 62408

Chris Lattner d32480d3db this massive patch introduces a simple new abstraction: it makes 
"FileID" a concept that is now enforced by the compiler's type checker
instead of yet-another-random-unsigned floating around.

This is an important distinction from the "FileID" currently tracked by
SourceLocation.  *That* FileID may refer to the start of a file or to a
chunk within it.  The new FileID *only* refers to the file (and its 
#include stack and eventually #line data), it cannot refer to a chunk.

FileID is a completely opaque datatype to all clients, only SourceManager
is allowed to poke and prod it.

Bill Wendling 4d5275905e Implement a special algorithm for converting uint_to_fp for i32 values on 
X86. This code:

void f() {
  uint32_t x;
  float y = (float)x;
}

used to be:

     movl     %eax, -8(%ebp)
     movl     [2^52 double], -4(%ebp)
     movsd    -8(%ebp), %xmm0
     subsd    [2^52 double], %xmm0
     cvtsd2ss %xmm0, %xmm0

Is now:

   movsd        [2^52 double], %xmm0
   movsd        %xmm0, %xmm1
   movd         %ecx, %xmm2
   orps         %xmm2, %xmm1
   subsd        %xmm0, %xmm1
   cvtsd2ss     %xmm1, %xmm0

This is faster on X86. Note that there's an extra load of %xmm0 into %xmm1. That
will be fixed in a later coalescer fix.

Chris Lattner 800979259e make "ContentCache::Buffer" mutable to avoid a const_cast. 
llvm-svn: 62403
 2009-01-17 03:54:16 +00:00
Chris Lattner 1ed28ce3fd no need to check this: content cache is already 1-1 map with fileentries. 
llvm-svn: 62402
 2009-01-17 03:49:48 +00:00
Chris Lattner 1abd20901b Instead of iterating over FileID's, have PTH generation iterate over the 
content cache directly.  Content cache has a 1-1 mapping with fileentries,
whereas multiple FileIDs can be the same FileEntry.
