* For PR1064:Reid Spencer2007-01-125-95/+139
| | | | | | | | | | | | | | | | | | | | | | | Implement the arbitrary bit-width integer feature. The feature allows integers of any bitwidth (up to 64) to be defined instead of just 1, 8, 16, 32, and 64 bit integers. This change does several things: 1. Introduces a new Derived Type, IntegerType, to represent the number of bits in an integer. The Type classes SubclassData field is used to store the number of bits. This allows 2^23 bits in an integer type. 2. Removes the five integer Type::TypeID values for the 1, 8, 16, 32 and 64-bit integers. These are replaced with just IntegerType which is not a primitive any more. 3. Adjust the rest of LLVM to account for this change. Note that while this incremental change lays the foundation for arbitrary bit-width integers, LLVM has not yet been converted to actually deal with them in any significant way. Most optimization passes, for example, will still only deal with the byte-width integer types. Future increments will rectify this situation. llvm-svn: 33113
* Implement review feedback for the ConstantBool->ConstantInt merge. ChrisReid Spencer2007-01-122-2/+2
| | | | | | | | recommended that getBoolValue be replaced with getZExtValue and that get(bool) be replaced by get(const Type*, uint64_t). This implements those changes. llvm-svn: 33110
* Rename BoolTy as Int1Ty. Patch by Sheng Zhou.Reid Spencer2007-01-112-4/+4

* For PR411:Reid Spencer2007-01-067-56/+88
| | | | | | | | | Take an incremental step towards type plane elimination. This change separates types from values in the symbol tables by finally making use of the TypeSymbolTable class. This yields more natural interfaces for dealing with types and unclutters the SymbolTable class. llvm-svn: 32956
* For PR950:Reid Spencer2006-12-313-57/+44
| | | | | | | | | | | | | | Update for signless integer types and parameter attribute implementation. Of significant note: 1. This changes the bytecode format yet again. 2. There are 1/2 as many integer type planes (this is a good thing) 3. GEP indices now use only 1 bit to identify their type which means more GEP instructions won't be relegated to format 0 (size win) 4. Parameter attributes are implemented but currently being stored verbosely for each function type. Some other day this needs to be optimized for size. llvm-svn: 32783

| | | | | | | rework the hacks that had us passing OStream in. We pass in std::ostream* instead, check for null, and then dispatch to the correct print() method. llvm-svn: 32636

* Fix long standing issue with propagating error message back to caller. ThisReid Spencer2006-12-152-7/+17
| | | | | | | | has been a problem since exceptions were removed from the BytecodeReader. Error messages are now captured from ModuleProvider::releaseModule as well as after a longjmp. llvm-svn: 32608

* Fix a CmpInst writing bug by removing merge cruft that I *know* I've removedReid Spencer2006-12-061-9/+4

* Replacing std::iostreams with llvm iostreams. Some of these changes involveBill Wendling2006-11-292-11/+12
| | | | | | | adding a temporary wrapper around the ostream to make it friendly to functions expecting an LLVM stream. This should be fixed in the future. llvm-svn: 31990

* For PR950:Reid Spencer2006-11-273-64/+210
| | | | | | | | | | The long awaited CAST patch. This introduces 12 new instructions into LLVM to replace the cast instruction. Corresponding changes throughout LLVM are provided. This passes llvm-test, llvm/test, and SPEC CPUINT2000 with the exception of 175.vpr which fails only on a slight floating point output difference. llvm-svn: 31931

* For PR950:Reid Spencer2006-11-081-3/+15
| | | | | | | | This patch converts the old SHR instruction into two instructions, AShr (Arithmetic) and LShr (Logical). The Shr instructions now are not dependent on the sign of their operands. llvm-svn: 31542
* Remove some dead code.Reid Spencer2006-11-031-2/+1
| | | | llvm-svn: 31401
* For PR786:Reid Spencer2006-11-022-2/+1
| | | | | | | | | | Turn on -Wunused and -Wno-unused-parameter. Clean up most of the resulting fall out by removing unused variables. Remaining warnings have to do with unused functions (I didn't want to delete code without review) and unused variables in generated code. Maintainers should clean up the remaining issues when they see them. All changes pass DejaGnu tests and Olden. llvm-svn: 31380
* For PR950:Reid Spencer2006-11-021-8/+13
| | | | | | Replace the REM instruction with UREM, SREM and FREM. llvm-svn: 31369
* For PR950:Reid Spencer2006-10-263-374/+717
| | | | | | | | 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
* For PR950:Reid Spencer2006-10-202-19/+17
| | | | | | | | This patch implements the first increment for the Signless Types feature. All changes pertain to removing the ConstantSInt and ConstantUInt classes in favor of just using ConstantInt. llvm-svn: 31063
* Fix massive resource leaks in the bytecode reader. Reading a bytecode fileChris Lattner2006-10-122-45/+46
| | | | | | | | | 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

* Adding dllimport, dllexport and external weak linkage types.Anton Korobeynikov2006-09-142-9/+40
| | | | | | | | | DLL* linkages got full (I hope) codegeneration support in C & both x86 assembler backends. External weak linkage added for future use, we don't provide any codegeneration, etc. support for it. llvm-svn: 30374

* For PR797:Reid Spencer2006-08-254-25/+20
| | | | | | | | | | | | | | | Final commit for this bug. This removes the last EH holdouts in LLVM and turns off exception support by using the -fno-exceptions option.
