2011-03-02Extend initial support for primitive types in PTX backendChe-Liang Chiou
- Allow i16, i32, i64, float, and double types, using the native .u16, .u32, .u64, .f32, and .f64 PTX types. - Allow loading/storing of all primitive types. - Allow primitive types to be passed as parameters. - Allow selection of PTX Version and Shader Model as sub-target attributes. - Merge integer/floating-point test cases for load/store. - Use .u32 instead of .s32 to conform to output from NVidia nvcc compiler.

2011-03-02Move extendRange() into SplitEditor and delete the LiveRangeMap class.Jakob Stoklund Olesen
Extract the updateSSA() method from the too long extendRange(). LiveOutCache can be shared among all the new intervals since there is at most one of the new ranges live out from each basic block. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@126818 91177308-0d34-0410-b5e6-96231b3b80d8

2011-03-02Move LiveIntervalMap::extendTo into LiveInterval itself.Jakob Stoklund Olesen
This method could probably be used by LiveIntervalAnalysis::shrinkToUses, and now it can use extendIntervalEndTo() which coalesces ranges. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@126803 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@126801 91177308-0d34-0410-b5e6-96231b3b80d8
2011-03-01Move the value map from LiveIntervalMap to SplitEditor.Jakob Stoklund Olesen
The value map is currently not used, all values are 'complex mapped' and LiveIntervalMap::mapValue is used to dig them out. This is the first step in a series changes leading to the removal of LiveIntervalMap. Its data structures can be shared among all the live intervals created by a split, so it is wasteful to create a copy for each. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@126800 91177308-0d34-0410-b5e6-96231b3b80d8

2011-03-01If argument numbering is encoded in metadata then emit arguments' debug info ↵Devang Patel
in that order. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@126794 91177308-0d34-0410-b5e6-96231b3b80d8
2011-03-01Today, the language front ends produces llvm.dbg.* intrinsics, used to ↵Devang Patel
encode arguments' debug info, in order any way, most of the times. However, if a front end mix-n-matches llvm.dbg.declare and llvm.dbg.value intrinsics to encode debug info for arguments then code generator needs a way to find argument order. Use 8 bits from line number field to keep track of argument ordering while encoding debug info for an argument. That leaves 24 bit for line no, DebugLoc also allocates 24 bit for line numbers. If a function has more than 255 arguments then rest of the arguments will be ordered by llvm.dbg.* intrinsics' ordering in IR. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@126793 91177308-0d34-0410-b5e6-96231b3b80d8

On the first cmake run before the caches has been updated with the default options, options defined after HandleLLVMOptions are always treated as off inside HandleLLVMOptions.

2011-03-01Change directory_entry::path() to return a const std::string & instead ofDan Gohman
a StringRef, for the benefit of clients that want the result as a nul-terminated string. Clients that expect a StringRef will get one via the implicit conversion. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@126784 91177308-0d34-0410-b5e6-96231b3b80d8
2011-03-01Stop computing the number of uses twice per value in CodeGenPrepare's sinking ofCameron Zwarich
addressing code. On 403.gcc this almost halves CodeGenPrepare time and reduces total llc time by 9.5%. Unfortunately, getNumUses() is still the hottest function in llc. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@126782 91177308-0d34-0410-b5e6-96231b3b80d8
2011-03-01Keep track of which stage produced a live range, and bypass earlier stages ↵Jakob Stoklund Olesen
when revisiting. This effectively disables the 'turbo' functionality of the greedy register allocator where all new live ranges created by splitting would be reconsidered as if they were originals. There are two reasons for doing this, 1. It guarantees that the algorithm terminates. Early versions were prone to infinite looping in certain corner cases. 2. It is a 2x speedup. We can skip a lot of unnecessary interference checks that won't lead to good splitting anyway. The problem is that region splitting only gets one shot, so it should probably be changed to target multiple physical registers at once. Local live range splitting is still 'turbo' enabled. It only accounts for a small fraction of compile time, so it is probably not necessary to do anything about that. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@126781 91177308-0d34-0410-b5e6-96231b3b80d8
