2007-11-21This change does a couple of things. First it gets the Visual Studio builds ↵Chuck Rose III
working. I added the lexing files to the VStudio projects and removed the .l files from the VStudio projects. There was a problem with use of strtoll in TGLexer.cpp and Chris suggested switching to strtol, so that's included here. Additionally, this checkin adds minimal x64 builds to the VStudio builds. Build issues related to x64 in the windows specific files for DynamicLibrary.inc and Singals.inc are worked around, but not ultimately solved. Binaries used to be stored in ...\win32\{Debug|Release} but are now kept in ...\win32\bin\{win32|x64}\{Debug|Release} intermediate files will continue to be stored in the individual project directories under win32. Some names will likely change in the future to reflect that the vstudio projects are no longer 32-bit only, but I wanted to get things up and running today so kept away from bigger restructuring. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@44260 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

2007-11-19ExpandUnalignedLoad doesn't handle vectors right at all apparently.Chris Lattner
Fix a couple of problems: 1. Don't assume the VT-1 is a VT that is half the size. 2. Treat vectors of FP in the vector path, not the FP path. This has a couple of remaining problems before it will work with the code in PR1811: the code below this change assumes that it can use extload/shift/or to construct the result, which isn't right for vectors. This also doesn't handle vectors of 1 or vectors that aren't pow-2. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@44243 91177308-0d34-0410-b5e6-96231b3b80d8

2007-11-17Live interval splitting:Evan Cheng
When a live interval is being spilled, rather than creating short, non-spillable intervals for every def / use, split the interval at BB boundaries. That is, for every BB where the live interval is defined or used, create a new interval that covers all the defs and uses in the BB. This is designed to eliminate one common problem: multiple reloads of the same value in a single basic block. Note, it does *not* decrease the number of spills since no copies are inserted so the split intervals are *connected* through spill and reloads (or rematerialization). The newly created intervals can be spilled again, in that case, since it does not span multiple basic blocks, it's spilled in the usual manner. However, it can reuse the same stack slot as the previously split interval. This is currently controlled by -split-intervals-at-bb. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@44198 91177308-0d34-0410-b5e6-96231b3b80d8

2007-11-14Clean up sub-register implementation by moving subReg information back toEvan Cheng
MachineOperand auxInfo. Previous clunky implementation uses an external map to track sub-register uses. That works because register allocator uses a new virtual register for each spilled use. With interval splitting (coming soon), we may have multiple uses of the same register some of which are of using different sub-registers from others. It's too fragile to constantly update the information. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@44104 91177308-0d34-0410-b5e6-96231b3b80d8
