Gabor Greif e16561cd5d Here is the bulk of the sanitizing. 
Almost all occurrences of "bytecode" in the sources have been eliminated.

Dan Gohman a866514528 Generalize MVT::ValueType and associated functions to be able to represent 
extended vector types. Remove the special SDNode opcodes used for pre-legalize
vector operations, and the special MVT::Vector type used with them. Adjust
lowering and legalize to work with the normal SDNode kinds instead, and to
use the normal MVT functions to work with vector types instead of using the
two special operands that the pre-legalize nodes held.

This allows pre-legalize and post-legalize DAGs, and the code that operates
on them, to be more consistent. Pre-legalize vector operators can be handled
more consistently with scalar operators. And, -view-dag-combine1-dags and
-view-legalize-dags now look prettier for vector code.

Reid Spencer bdf03b4174 Reinstate the patch for escaping non-printing characters and allow for 
\\ to escape \. All these cases are now handled by the AsmParser.

llvm-svn: 37295
 2007-05-22 19:27:35 +00:00
Chris Lattner 83d7dd419a temporarily revert reid's asmwriter patch, it is missing the asmparser piece 
that decodes the escape sequences, thus breaking all cases that use them.

This fixes test/Assembler/2007-05-21-Escape.ll

llvm-svn: 37284

llvm-svn: 37261
 2007-05-19 14:44:42 +00:00
Reid Spencer 6473fb7916 Adjust how LLVM names are produced: 
1. Always use % for local and @ for global.
2. Replace NameNeedsQuotes with QuoteNameIfNeeded so that any adjustments
   to the name can be done in one pass.
3. Implement generation of hex escapes so we don't get "wonky" characters
   in the output.

Chris Lattner a919f6dddc if functiontype is going to have a pointer to a paramattr object, it better 
be const.  The only way to get a pointer to these returns a const pointer.

llvm-svn: 36662
 2007-05-03 01:11:54 +00:00
Devang Patel e95c6ad802 Use 'static const char' instead of 'static const int'. 
Due to darwin gcc bug, one version of darwin linker coalesces
static const int, which defauts PassID based pass identification.

llvm-svn: 36652
 2007-05-02 21:39:20 +00:00
Devang Patel 0f88f76cfe Re-install patch to enable use of PassID.

Chris to revert this patch earlier.
