Reid Spencer 09575bac2e For PR1195: 
Change use of "packed" term to "vector" in comments, strings, variable
names, etc.

llvm-svn: 34300
 2007-02-15 03:39:18 +00:00
Reid Spencer d84d35ba70 For PR1195: 
Rename PackedType -> VectorType, ConstantPacked -> ConstantVector, and
PackedTyID -> VectorTyID. No functional changes.

Chris Lattner 4da5e17cfc From Dan Gohman: 
While preparing http://llvm.org/PR1198 I noticed several asserts
protecting unprepared code from i128 types that weren't actually failing
when they should because they were written as assert("foo") instead of
something like assert(0 && "foo"). This patch fixes all the cases that a
quick grep found.

Chris Lattner e786eaa3b0 Use a SmallVector to reduce heap traffic. This speeds up bcreader 10%

Chris Lattner abe7342dc2 now that we can pass ranges into CallInst ctors, eliminate vector heap traffic

Chris Lattner 4d8861efaa stop passing vector into ctors 
llvm-svn: 34218
 2007-02-13 01:53:54 +00:00
Chris Lattner 8d160d68b8 avoid creating a temporary string when reading the symbol table for a 
module.  This speeds up the bcreader 11%.

llvm-svn: 34198
 2007-02-12 18:53:43 +00:00
Chris Lattner 32ab643df7 Switch ValueSymbolTable to use StringMap<Value*> instead of std::map<std::string, Value*> 
as its main datastructure.  There are many improvements yet to be made, but
this speeds up opt --std-compile-opts on 447.dealII by 7.3%.

llvm-svn: 34193
 2007-02-12 05:18:08 +00:00
Reid Spencer 0aea61a57e Undo the last patch. It slowed down bcwriter by 1.8% but only sped up 
the bc reader by 0.8%. Deemed "not worth it"

llvm-svn: 34169
 2007-02-11 00:03:39 +00:00
Reid Spencer 9aac907740 Compaction tables don't exist any more. 
llvm-svn: 34148
 2007-02-10 14:07:56 +00:00
Reid Spencer 6e4c277858 For PR1194: 
The bcreader counts on "primitive" types being inserted before they are
referenced in other types. With recent changes to the bcwriter, this fact
became exposed since IntegerType is no longer "primitive". We can no longer
count on all IntegerTypes being inserted early. This patch modifies
getOrCreateTypeSlot to insert any sub-type that can't possibly recurse
before we create the slot for the type. This has the benefit of reducing
the number of OpaqueType objects the reader needs to deal with.

Reid Spencer 1673159125 Fix a comment.

Chris Lattner 31b60980dc Change the table datastructure to be a vector<smallvector>, instead of 
vector<vector> to avoid allocations.  This speeds up bcwriting of 447.dealII
from 0.8276 to 0.7637s (8.4%).

This concludes this round of proding the bcwriter into submission.  Final
speedup from 24.4s to 0.7637s (32x).

Chris Lattner d7f677c590 Make BytecodeWriter::outputValueSymbolTable *significantly* less abusive 
of memory, through a combination of DenseMap and SmallVector.  This speeds
up bcwriter on 447.dealII from 1.31s to 0.82s (60% faster).

llvm-svn: 34141
 2007-02-10 07:31:44 +00:00
Chris Lattner 2aed25cfc9 make the datastructure used in BytecodeWriter::outputValueSymbolTable 
*slightly* less abusive of memory.  This speeds up the bcwriter from
1.83s to 1.32s (39% faster) on 447.dealII.

llvm-svn: 34140
 2007-02-10 07:11:51 +00:00
Chris Lattner 05aeb105df Switch typemap over to DenseMap. No significant speedup. 
llvm-svn: 34139
 2007-02-10 07:06:46 +00:00
Chris Lattner 9082be2593 Switch NodeMap from an std::map to a DenseMap. This speeds up bcwriting 
of 447.dealII from 3.3s to 1.8s (80% faster).

Chris Lattner cdde9ce28b The ModuleLevel vector is often quite sparse. Switch it to a DenseMap. This 
speeds up bcwriting of 447.dealII by 40%, from 4.63s to 3.32s.

llvm-svn: 34135
 2007-02-10 06:38:19 +00:00
Chris Lattner e06c2fd4df Make the ModuleLevel datastructure more sane. When a function-local value 
is inserted into the table, it remembers that the value needs to be popped
off.  This makes purgeFunction much faster, speeding up bcwriting of 447.dealII
from 6.8->4.6s (47%).

llvm-svn: 34133
 2007-02-10 06:09:41 +00:00
Chris Lattner 82a06ec1ca Only compute the module levels info once per module, instead of once 
per function.  This speeds up bcwriting on 447.dealII from 10.16s to 6.81s
(49%).

llvm-svn: 34132
 2007-02-10 05:54:33 +00:00
Chris Lattner a6214fea08 Clone and specialize CreateSlotIfNeeded into CreateFunctionValueSlot to handle 
function-local values.  This speeds up bcwriting a small 2.2% (10.384->10.156s
on 447.dealII), but paves the way for more important changes.

Chris Lattner ce57e528f5 getSlot can never fail. Make it assert internally, eliminate checks in 
clients.  Same for getTypeSlot.

Reid Spencer 5808739fac Use int32_t and uint32_t to hopefully help weak compilers (cygwin) not 
generate errors about being unable to resolve overloaded type.

Chris Lattner b3905c70c4 remove dead code, the outputConstants function is now only called at module scope. 
llvm-svn: 34085
 2007-02-09 07:53:20 +00:00
Chris Lattner fc30d1bb69 1. constants can never occur in the symbol table. 
2. All function-level constants are now incorporated into the module-level
  constant pool, since the compaction table was removed.  Eliminate extra
  work to check for them.

This speeds up the bcwriter from 24.4s to 13.1s on 447.dealII and .73 -> .56s
on kc++ in a release build.

Chris Lattner daba41cfb9 move AnalyzeBytecodeFile out of ReaderWrappers.cpp into Analyzer.cpp. Now 
lli doesn't link in Analyzer.cpp.

Chris Lattner a0e49f2ead push bytecode decompressor out through APIs. Now the bytecode reader 
api's look like this:

ModuleProvider *getBytecodeModuleProvider(
  const std::string &Filename,  ///< Name of file to be read
  BCDecompressor_t *BCDC = Compressor::decompressToNewBuffer,
  std::string* ErrMsg = 0,      ///< Optional error message holder
  BytecodeHandler* H = 0        ///< Optional handler for reader events
);

This is ugly, but allows a client to say:

  getBytecodeModuleProvider("foo", 0);

If they do this, there is no dependency on the compression libraries, saving
codesize.

llvm-svn: 34012
 2007-02-07 21:41:02 +00:00
Chris Lattner 41f5c64ae1 Move compressor out of the core Reader.cpp file.
