* Switch spill weights from a basic loop depth estimation to BlockFrequencyInfo.Benjamin Kramer2013-06-17
| | | | | | | | | | | | | | | | | | The main advantages here are way better heuristics, taking into account not just loop depth but also __builtin_expect and other static heuristics and will eventually learn how to use profile info. Most of the work in this patch is pushing the MachineBlockFrequencyInfo analysis into the right places. This is good for a 5% speedup on zlib's deflate (x86_64), there were some very unfortunate spilling decisions in its hottest loop in longest_match(). Other benchmarks I tried were mostly neutral. This changes register allocation in subtle ways, update the tests for it. 2012-02-20-MachineCPBug.ll was deleted as it's very fragile and the instruction it looked for was gone already (but the FileCheck pattern picked up unrelated stuff). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@184105 91177308-0d34-0410-b5e6-96231b3b80d8

* Fix incorrectly finding 'executable' directories instead of files.Manuel Klimek2013-06-17
| | | | | | | | | | | | | | | This broke for example the 'not' utility, if a directory called 'FileCheck' is executable and in the path before the actual 'FileCheck'. This patch steals the implementation of the "old" PathV1 canExecute implementation: - checks for R_OK (file readable): this is necessary for executing scripts; we should not regress here unless we have good reasons - checks for S_ISREG; if we want to get rid of this, we'd need to change all callers who already made the assumption when depending on Path V1. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@184074 91177308-0d34-0410-b5e6-96231b3b80d8
* DebugInfo: remove target-specific Frame Index handling for DBG_VALUE ↵David Blaikie2013-06-16
| | | | | | | | | | MachineInstrs Frame index handling is now target-agnostic, so delete the target hooks for creation & asm printing of target-specific addressing in DBG_VALUEs and any related functions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@184067 91177308-0d34-0410-b5e6-96231b3b80d8
* Debug Info: Simplify Frame Index handling in DBG_VALUE Machine InstructionsDavid Blaikie2013-06-16
| | | | | | | | | | | | | | | | | | | | Rather than using the full power of target-specific addressing modes in DBG_VALUEs with Frame Indicies, simply use Frame Index + Offset. This reduces the complexity of debug info handling down to two representations of values (reg+offset and frame index+offset) rather than three or four. Ideally we could ensure that frame indicies had been eliminated by the time we reached an assembly or dwarf generation, but I haven't spent the time to figure out where the FIs are leaking through into that & whether there's a good place to convert them. Some FI+offset=>reg+offset conversion is done (see PrologEpilogInserter, for example) which is necessary for some SelectionDAG assumptions about registers, I believe, but it might be possible to make this a more thorough conversion & ensure there are no remaining FIs no matter how instruction selection is performed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@184066 91177308-0d34-0410-b5e6-96231b3b80d8

* MI-Sched: added tracking of dependent latency for better heuristics.Andrew Trick2013-06-15
| | | | | | | | | | | | | | Heuristics compare the critical path in the scheduled code, called ExpectedLatency, with the latency of instructions remaining to be scheduled. There are two ways to look at remaining latency: (1) Dependent latency includes the latency between unscheduled and scheduled instructions. (2) Independent latency is simply the height (bottom-up) or depth (top-down) of instructions currently in the ready Q. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@184029 91177308-0d34-0410-b5e6-96231b3b80d8

* Remove the LLVM specific archive index.Rafael Espindola2013-06-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Archive files (.a) can have a symbol table indicating which object files in them define which symbols. The purpose of this symbol table is to speed up linking by allowing the linker the read only the .o files it is actually going to use instead of having to parse every object's symbol table. LLVM's archive library currently supports a LLVM specific format for such table. It is hard to see any value in that now that llvm-ld is gone: * System linkers don't use it: GNU ar uses the same plugin as the linker to create archive files with a regular index. The OS X ar creates no symbol table for IL files, I assume the linker just parses all IL files. * It doesn't interact well with archives having both IL and native objects. * We probably don't want to be responsible for yet another archive format variant. This patch then: * Removes support for creating and reading such index from lib/Archive. * Remove llvm-ranlib, since there is nothing left for it to do. We should in the future add support for regular indexes to llvm-ar for both native and IL objects. When we do that, llvm-ranlib should be reimplemented as a symlink to llvm-ar, as it is equivalent to "ar s". git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@184019 91177308-0d34-0410-b5e6-96231b3b80d8
