* 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

| | | | | | | | | | | | | When we're rematerializing into a not-quite-right register we already add the real definition as an imp-def, but we should also be marking the "official" register as dead, since nothing else is going to use it as a result of this remat.

* Enable FastISel on ARM for Linux and NaCl, not MCJITJF Bastien2013-06-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a resubmit of r182877, which was reverted because it broken MCJIT tests on ARM. The patch leaves MCJIT on ARM as it was before: only enabled for iOS. I've CC'ed people from the original review and revert. FastISel was only enabled for iOS ARM and Thumb2, this patch enables it for ARM (not Thumb2) on Linux and NaCl, but not MCJIT. Thumb2 support needs a bit more work, mainly around register class restrictions. The patch punts to SelectionDAG when doing TLS relocation on non-Darwin targets. I will fix this and other FastISel-to-SelectionDAG failures in a separate patch. The patch also forces FastISel to retain frame pointers: iOS always keeps them for backtracking (so emitted code won't change because of this), but Linux was getting much worse code that was incorrect when using big frames (such as test-suite's lencod). I'll also fix this in a later patch, it will probably require a peephole so that FastISel doesn't rematerialize frame pointers back-to-back. The test changes are straightforward, similar to: http://lists.cs.uiuc.edu/pipermail/llvm-commits/Week-of-Mon-20130513/174279.html They also add a vararg test that got dropped in that change. I ran all of lnt test-suite on A15 hardware with --optimize-option=-O0 and all the tests pass. All the tests also pass on x86 make check-all. I also re-ran the check-all tests that failed on ARM, and they all seem to pass. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@183966 91177308-0d34-0410-b5e6-96231b3b80d8
