* Add a 'deleteModule' method to the Linker class.Bill Wendling2013-10-162-1/+9
| | | | | | | | This deletes the Module ivar instead of having the LTO code generater do it. It also sets the pointer to 'NULL', so that if it's used again it will abort quickly. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@192778 91177308-0d34-0410-b5e6-96231b3b80d8

* Fix a pair of bugs in the emission of pubname tables:Eric Christopher2013-10-162-6/+16
| | | | | | | | | | | | | | | | 1) Make sure we emit static member variables by checking at the end of createGlobalVariableDIE rather than piecemeal in the function. (As a note, createGlobalVariableDIE needs rewriting.) 2) Make sure we use the definition rather than declaration DIE for two things: a) determining linkage for gnu pubnames, and b) as the address of the DIE for global variables. (As a note, createGlobalVariableDIE really needs rewriting.) Adjust the testcase to make sure we're checking the correct DIEs. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@192761 91177308-0d34-0410-b5e6-96231b3b80d8

* MC: Better handling of tricky symbol and section namesHans Wennborg2013-10-164-20/+38
| | | | | | | | | | | | | | | | | Because of win32 mangling, we produce symbol and section names with funny characters in them, most notably @ characters. MC would choke on trying to parse its own assembly output. This patch addresses that by: - Making @ trigger quoting of symbol names - Also quote section names in the same way - Just parse section names like other identifiers (to allow for quotes) - Don't assume @ signifies a symbol variant if it is in a string.

* Enable MI Sched for x86.Andrew Trick2013-10-151-1/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | This changes the SelectionDAG scheduling preference to source order. Soon, the SelectionDAG scheduler can be bypassed saving a nice chunk of compile time. Performance differences that result from this change are often a consequence of register coalescing. The register coalescer is far from perfect. Bugs can be filed for deficiencies. On x86 SandyBridge/Haswell, the source order schedule is often preserved, particularly for small blocks. Register pressure is generally improved over the SD scheduler's ILP mode. However, we are still able to handle large blocks that require latency hiding, unlike the SD scheduler's BURR mode. MI scheduler also attempts to discover the critical path in single-block loops and adjust heuristics accordingly. The MI scheduler relies on the new machine model. This is currently unimplemented for AVX, so we may not be generating the best code yet. Unit tests are updated so they don't depend on SD scheduling heuristics. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@192750 91177308-0d34-0410-b5e6-96231b3b80d8

* Path: Recognize Windows compiled resource file.Rui Ueyama2013-10-154-1/+12
| | | | | | | | | | | | | | Some background: One can pass compiled resource files (.res files) directly to the linker on Windows. If a resource file is given, the linker will run "cvtres" command in background to convert the resource file to a COFF file to link it. What I'm trying to do with this patch is to make the linker to recognize the resource file by file magic, so that it can run cvtres command.

* Fix the ExecutionDepsFix pass to handle AVX instructions.Andrew Trick2013-10-144-38/+164
| | | | | | | | | | | | | | | | | | | | | | | | This pass is needed to break false dependencies. Without it, unlucky register assignment can result in wild (5x) swings in performance. This pass was trying to handle AVX but not getting it right. AVX doesn't have partial register defs, it has unused register reads in which the high bits of a source operand are copied into the unused bits of the dest. Fixing this requires conservative liveness analysis. This is awkard because the pass already has its own pseudo-liveness. However, proper liveness is expensive, and we would like to use a generic utility to compute it. The fix only invokes liveness on-demand. It is rare to detect a case that needs undef-read dependence breaking, but when it happens, it can be needed many times within a very large block. I think the existing heuristic which uses a register window of 16 is too conservative for loop-carried false dependencies. If the loop is a reduction. The out-of-order engine may be able to execute several loop iterations in parallel. However, I'll leave this tuning exercise for next time. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@192635 91177308-0d34-0410-b5e6-96231b3b80d8
