Chris Lattner faaf32db19 Change all of the bytecode reader primitives to throw exceptions instead of 
returning error codes.  Because they don't return an error code, they can
return the value read, which simplifies the code and makes the reader more
efficient (yaay!).

Also eliminate the special case code for little endian machines.

Chris Lattner b94550e537 Change the Opcode enum for PHI nodes from "Instruction::PHINode" to "Instruction::PHI" to be more consistent with the other instructions.

Chris Lattner 7c6c539296 * New revised variable argument handling support 
* More dense bytecode encoding for varargs calls (like printf)
* Eliminated the extremely old bytecode format.  rev #0 is now 1.0

llvm-svn: 9220
 2003-10-18 05:54:18 +00:00
Chris Lattner 2ec9de30cd Reserve space for PHI nodes when we read them in. This provides a VERY 
tasty 15% speedup on the testcase from Bill.

Chris Lattner 5255bed8bc Use the version of getValue that takes the type plane instead of the type 
if possible.  This provides a consistent 8.5% speedup.

Chris Lattner e7691a4520 Major refactoring of the bytecode reader. This includes the following 
changes:
  * BytecodeReader::getType(...) used to return a null pointer
    on error.  This was only checked about half the time.  Now we convert
    it to throw an exception, and delete the half that checked for error.
    This was checked in before, but psmith crashed and lost the change :(
  * insertValue no longer returns -1 on error, so callers don't need to
    check for it.
  * Substantial rewrite of InstructionReader.cpp, to use more efficient,
    simpler, data structures.  This provides another 5% speedup.  This also
    makes the code much easier to read and understand.

Chris Lattner bd26abdc95 Significantly clean up parsing of instructions. This exceptionizes and 
simplifies the control flow a bit.  This provides a small (~3%) speedup,
but it's primarily a cleanup exercise.

llvm-svn: 8983
 2003-10-09 18:25:19 +00:00
Chris Lattner abf6412c09 This patch substantially simplifies and cleans up handling of basic blocks 
in the bytecode parser.  Before we tried to shoehorn basic blocks into the
"getValue" code path with other types of values.  For a variety of reasons
this was a bad idea, so this patch separates it out into its own data structure.

This simplifies the code, makes it fit in 80 columns, and is also much faster.
In a testcase provided by Bill, which has lots of PHI nodes, this patch speeds
up bytecode parsing from taking 6.9s to taking 2.32s.  More speedups to
follow later.

Chris Lattner 85555779de Various cleanups and simplifications. This speeds up reading a bytecode file 
Bill gave me from 8.69s to 6.90s.

If you still have these suckers laying around, you have GOT to rebuild them.  geeze.

Chris Lattner 69ce8674b5 - Rename Instruction::First*Op to *OpsBegin, and Num*Ops to *OpsEnd to 
reflect the fact that it's a range being defined.

Chris Lattner dc23308820 Emit an obnoxious warning message for bytecode that includes load/store 
instructions that use indexing.  Convert them transparently into a pair
of instructions.

Chris Lattner 51fa0ef925 - Finally nailed: test/Regression/Assembler/2002-08-16-ConstExprInlined.llx 
- ParseConstantPool was resolving reference to value using the function
      slot # instead of the global slot #.
  - Bytecode reader changes:
    - Remove the failure<> template from Bytecode Reader
    - Remove extraneous #includes
    - s/method/function/ a bit
    - Eliminate the fwdRefs class that just added abstraction where it was not
      needed, making things more complex.
    - Use a vector instead of a list for function signatures.

 2002-08-17 22:01:27 +00:00
Chris Lattner 330b7ac76c Remove support for Not ConstantExpr. This simplifies the unary case to only 
have to support the cast instruction, so the function is renamed to getCast.
