2007-12-17Bring back int_x86_sse2_movl_dq intrinsic for backward compatibility. Make sureEvan Cheng
it's auto-upgraded to a shufflevector instruction. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45131 91177308-0d34-0410-b5e6-96231b3b80d8
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45082 91177308-0d34-0410-b5e6-96231b3b80d8
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@44858 91177308-0d34-0410-b5e6-96231b3b80d8
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@44769 91177308-0d34-0410-b5e6-96231b3b80d8

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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@44359 91177308-0d34-0410-b5e6-96231b3b80d8
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@44250 91177308-0d34-0410-b5e6-96231b3b80d8

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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@42865 91177308-0d34-0410-b5e6-96231b3b80d8

Next round of x87 long double stuff. Getting close now, basically works. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@41875 91177308-0d34-0410-b5e6-96231b3b80d8
2007-09-11Add APInt interfaces to APFloat (allows directlyDale Johannesen

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.) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@41747 91177308-0d34-0410-b5e6-96231b3b80d8

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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@40974 91177308-0d34-0410-b5e6-96231b3b80d8
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@40807 91177308-0d34-0410-b5e6-96231b3b80d8
