* For PR950:Reid Spencer2006-10-261-0/+19
| | | | | | | | Make necessary changes to support DIV -> [SUF]Div. This changes llvm to have three division instructions: signed, unsigned, floating point. The bytecode and assembler are bacwards compatible, however. llvm-svn: 31195
* Fix massive resource leaks in the bytecode reader. Reading a bytecode fileChris Lattner2006-10-121-6/+6
| | | | | | | | | with ParseBytecodeFile used to leak both a ModuleProvider (and related bytecode parser stuff attached to it) AND a file descriptor, which was never closed. This prevented gccld/llvm-ld/llvm-link from linking together apps with more that ~252 .bc files on darwin. llvm-svn: 30912
* - Fixed broken Win32 buildAnton Korobeynikov2006-09-011-1/+1
| | | | | | - Removed warning about clobbered parameter in Bytecode/Reader llvm-svn: 30026
* For PR797:Reid Spencer2006-08-251-19/+8
| | | | | | | | | | | | | | | Final commit for this bug. This removes the last EH holdouts in LLVM and turns off exception support by using the -fno-exceptions option. This leads to the following reduction in library and executable sizes: DEBUG BUILD RELEASE BUILD before after delta before after delta lib 162,328K 157,616K 4,712 17,864K 16,416K 1,448K bin 571,444K 557,156K 14,288 63,296K 56,996K 6,300K Debug Improvement: 19,000K (2.59%) Release Improvement: 7,748K (9.55%) llvm-svn: 29882
* For PR797:Reid Spencer2006-08-221-3/+8
| | | | | | | | Make the Bytecode Reader use setjmp/longjump instead of exceptions to handle errors. The alternative was even uglier than setjmp/longjump as it would impact the interface and workings of nearly every function in the reader. llvm-svn: 29819

* Fix auto-upgrade of intrinsics to work properly with both assembly andReid Spencer2006-01-271-3/+3
| | | | | | | bytecode reading. This code is crufty, the result of much hacking to get things working correctly. Cleanup patches will follow. llvm-svn: 25682
* add bc reader/writer support for inline asmChris Lattner2006-01-251-2/+2
| | | | llvm-svn: 25621
* Add a flag to identify bytecode files that have intrinsic functions thatReid Spencer2006-01-191-0/+7
| | | | | | need to be upgraded. llvm-svn: 25445
* Use a map to cache the ModuleType information, so we can do logarithmicChris Lattner2005-10-031-0/+6
| | | | | | | | | | | | | 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. llvm-svn: 23611

* Add boolean file format flags in preparation for version 5 bytecode.Reid Spencer2004-08-211-3/+18
| | | | | | | | Remove the "processFunctions" boolean from ParseBytecode as it is no longer needed. This is part of avoiding double reading of functions when analyzing bytecode. llvm-svn: 15982
* Bytecode File Format Changes:Reid Spencer2004-08-171-2/+5
| | | | | | | | - File format version number bumped to 4 - Writer will now align nothing - Reader now only expects alignment for version 3 or earlier llvm-svn: 15875
* Make getGlobalTableValue not use getTypeSlot, this speeds up the bc readerChris Lattner2004-08-041-2/+3

* Do not do a linear std::find to reconstruct information we had, but later threwChris Lattner2004-08-031-12/+14

| | | | | | regression bug introduced in release 1.2 llvm-svn: 15219
* bug 263:Reid Spencer2004-07-251-0/+35
| | | | | | | | | | | | | | | | - 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. llvm-svn: 15210
* User ValueListTy as the type of the ValueList. This avoides the ValueListReid Spencer2004-07-181-1/+1
| | | | | | | from being treated like a Function which can cause the contents of the list to be come invalidated. llvm-svn: 14940
* - Rename two methods to give them more meaningReid Spencer2004-07-111-2/+8
| | | | | | | - Add read_float and read_double in preparation for a correct implementation of bytecode floating point support. llvm-svn: 14764
* Error Handling Cleanup:Reid Spencer2004-07-091-0/+2
| | | | | | | | | | - 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. llvm-svn: 14729
* Remove definition and use of OtherVal enumerator. This just fixes a thinko.Reid Spencer2004-07-061-1/+1
| | | | llvm-svn: 14634
* Finalize bytecode dumping. The "handleFinish" method was getting calledReid Spencer2004-07-051-3/+4
| | | | | | | | 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. llvm-svn: 14627
* - Make ValueList an "OtherVal" user of Values to ensure it doesn't getReid Spencer2004-07-041-60/+51
| | | | | | | | mistaken for anything else. - Move function descriptions to Reader.cpp file per Chris. - Remove tabs. llvm-svn: 14602
* This is a slimming down of the previous ReaderInternals.h that justReid Spencer2004-06-291-0/+470
declares the BytecodeReader class. llvm-svn: 14495
