2007-12-17Change the PointerType api for creating pointer types. The old functionality ↵Christopher Lamb
of PointerType::get() has become PointerType::getUnqual(), which returns a pointer in the generic address space. The new prototype of PointerType::get() requires both a type and an address space. llvm-svn: 45082
2007-12-11Implement address space attribute for LLVM pointer types. Address spaces are Christopher Lamb
regions of memory that have a target specific relationship, as described in the Embedded C Technical Report. This also implements the 2007-12-11-AddressSpaces test, which demonstrates how address space attributes can be used in LLVM IR. In addition, this patch changes the bitcode signature for stores (in a backwards compatible manner), such that the pointer type, rather than the pointee type, is encoded. This permits type information in the pointer (e.g. address space) to be preserved for stores. LangRef updates are forthcoming. llvm-svn: 44858
2007-12-10Adding a collector name attribute to Function in the IR. These Gordon Henriksen
methods are new to Function: bool hasCollector() const; const std::string &getCollector() const; void setCollector(const std::string &); void clearCollector(); The assembly representation is as such: define void @f() gc "shadow-stack" { ... The implementation uses an on-the-side table to map Functions to collector names, such that there is no overhead. A StringPool is further used to unique collector names, which are extremely likely to be unique per process. llvm-svn: 44769
2007-11-27Unbreak backwards compatibility with bytecode format. RegressionChris Lattner
introduced by this patch: http://lists.cs.uiuc.edu/pipermail/llvm-commits/Week-of-Mon-20071126/055824.html llvm-svn: 44364
2007-11-27Fix PR1146: parameter attributes are longer part ofDuncan Sands
the function type, instead they belong to functions and function calls. This is an updated and slightly corrected version of Reid Spencer's original patch. The only known problem is that auto-upgrading of bitcode files doesn't seem to work properly (see test/Bitcode/AutoUpgradeIntrinsics.ll). Hopefully a bitcode guru (who might that be? :) ) will fix it. llvm-svn: 44359
2007-11-20In order for parameter attribute uniquing to makeDuncan Sands
any sense it is important that ParamAttr::None gets treated the same as not supplying an attribute at all. Rather than stripping ParamAttr::None out of the list of attributes, assert if ParamAttr::None is seen. Fix up the bitcode reader which liked to insert ParamAttr::None all over the place. Patch based on one by Török Edwin. llvm-svn: 44250
2007-11-19Add explicit keywords.Dan Gohman
llvm-svn: 44234
2007-11-05Make labels work in asm blocks; allow labels asDale Johannesen
parameters. Rename ValueRefList to ParamList in AsmParser, since its only use is for parameters. llvm-svn: 43734
2007-10-11Next PPC long double bits. First cut at constants.Dale Johannesen
No compile-time support for constant operations yet, just format transformations. Make readers and writers work. Split constants into 2 doubles in Legalize. llvm-svn: 42865
2007-09-12Revise previous patch per review comments.Dale Johannesen
Next round of x87 long double stuff. Getting close now, basically works. llvm-svn: 41875
2007-09-11Add APInt interfaces to APFloat (allows directlyDale Johannesen
access to bits). Use them in place of float and double interfaces where appropriate. First bits of x86 long double constants handling (untested, probably does not work). llvm-svn: 41858
2007-09-07Revert previous change to IR.Dale Johannesen
llvm-svn: 41769
2007-09-06Next round of APFloat changes.Dale Johannesen
Use APFloat in UpgradeParser and AsmParser. Change all references to ConstantFP to use the APFloat interface rather than double. Remove the ConstantFP double interfaces. Use APFloat functions for constant folding arithmetic and comparisons. (There are still way too many places APFloat is just a wrapper around host float/double, but we're getting there.) llvm-svn: 41747
2007-09-04Update GEP constructors to use an iterator interface to fixDavid Greene
GLIBCXX_DEBUG issues. llvm-svn: 41697
2007-08-27Update InvokeInst to work like CallInstDavid Greene
llvm-svn: 41506
2007-08-09Patch 10 for long double. Doing constants right needs expanding ConstantFPDale Johannesen
to handle values bigger than double. If we assume host==target and host long double works correctly, this is not too bad, but we don't want to have that limitation longterm. I could implement accepting double constants as long double or something like that, which would lead to incorrect codegen with no errors; the more I think about that the worse it seems. Rather than do such a hack that would be backed out later, I'm settling for giving reasonable error messages, for now. llvm-svn: 40974
2007-08-04This is the patch to provide clean intrinsic function overloading support in ↵Chandler Carruth
LLVM. It cleans up the intrinsic definitions and generally smooths the process for more complicated intrinsic writing. It will be used by the upcoming atomic intrinsics as well as vector and float intrinsics in the future. This also changes the syntax for llvm.bswap, llvm.part.set, llvm.part.select, and llvm.ct* intrinsics. They are automatically upgraded by both the LLVM ASM reader and the bitcode reader. The test cases have been updated, with special tests added to ensure the automatic upgrading is supported. llvm-svn: 40807

pr1146 in llvm 2.1 without ugly code to emulate old behavior. This should be merged into the 2.0 release branch. llvm-svn: 36928

issues reid noticed last night. llvm-svn: 36785
2007-05-05Implement support for globally associating abbrevs with block IDs, whichChris Lattner
relieves us from having to emit the abbrevs into each instance of the block. This shrinks kc.bit from 3368K to 3333K, but will be a more significant win once instructions are abbreviated. The VST went from: Block ID #14 (VALUE_SYMTAB): Num Instances: 2345 Total Size: 1.29508e+07b/1.61885e+06B/404713W Average Size: 5522.73b/690.342B/172.585W % of file: 48.0645 Tot/Avg SubBlocks: 0/0 Tot/Avg Abbrevs: 7035/3 Tot/Avg Records: 120924/51.5667 % Abbrev Recs: 100 to: Block ID #14 (VALUE_SYMTAB): Num Instances: 2345 Total Size: 1.26713e+07b/1.58391e+06B/395978W Average Size: 5403.53b/675.442B/168.86W % of file: 47.5198 Tot/Avg SubBlocks: 0/0 Tot/Avg Abbrevs: 0/0 Tot/Avg Records: 120924/51.5667 % Abbrev Recs: 100 because we didn't emit the same 3 abbrevs 2345 times :) llvm-svn: 36767
