Chris Lattner bad09e71d0 Use a map to cache the ModuleType information, so we can do logarithmic
lookups instead of linear time lookups.  This speeds up bc parsing of a
large file from

137.834u 118.256s 4:27.96
to
132.611u 114.436s 4:08.53

with a release build.

Chris Lattner 6225146f20 Remove a dead field, make the map go to integer type ID to hash better and
avoid a getType.

Reid Spencer 8631bc3aaa Add boolean file format flags in preparation for version 5 bytecode.
Remove the "processFunctions" boolean from ParseBytecode as it is no
longer needed. This is part of avoiding double reading of functions
when analyzing bytecode.

Reid Spencer c3e436427b Bytecode File Format Changes:
- File format version number bumped to 4
- Writer will now align nothing
- Reader now only expects alignment for version 3 or earlier

Chris Lattner bba09b3f7f Make getGlobalTableValue not use getTypeSlot, this speeds up the bc reader
by 5% on eon

Chris Lattner cd84396b58 Do not do a linear std::find to reconstruct information we had, but later threw
away.  This speeds up by .bc reader by 30% in a profile build on 252.eon.

Reid Spencer bd72920331 Don't create a backwards compatibility flag for something that was a
regression bug introduced in release 1.2

llvm-svn: 15219
2004-07-25 21:32:51 +00:00
Reid Spencer b2bdb943b5 bug 263:
- encode/decode target triple and dependent libraries
bug 401:
- fix encoding/decoding of FP values to be little-endian only
bug 402:
- initial (compatible) cut at 24-bit types instead of 32-bit
- reduce size of block headers by 50%
Other:
- cleanup Writer by consolidating to one compilation unit, rem. other files
- use a std::vector instead of std::deque so the buffer can be allocated
  in multiples of 64KByte chunks rather than in multiples of some smaller
  (default) number.

Reid Spencer 1d8d08f34a User ValueListTy as the type of the ValueList. This avoides the ValueList
from being treated like a Function which can cause the contents of the list
to be come invalidated.

Reid Spencer db3bf19ad0 - Rename two methods to give them more meaning
- Add read_float and read_double in preparation for a correct
  implementation of bytecode floating point support.

Reid Spencer f3905c8511 Error Handling Cleanup:
- get rid of PARSE_ERROR macro
- add error(std::string) function
- use error(std::string) for all errors
- make input dependent asserts call error(std::string) instead
- ensure asserts are only for logic bugs, not input discrepancies.

Reid Spencer 02b6708e01 Finalize bytecode dumping. The "handleFinish" method was getting called
too soon so the function data was not getting dumped (it was generated
after the call handleFinish). Also cleaned up the output format for
proper indentation.

Reid Spencer e6c95490a0 - Make ValueList an "OtherVal" user of Values to ensure it doesn't get
mistaken for anything else.
- Move function descriptions to Reader.cpp file per Chris.
- Remove tabs.

Reid Spencer f4ec6383c0 This is a slimming down of the previous ReaderInternals.h that just
declares the BytecodeReader class.
