2013-05-31Apply LLVM upstream: r182877 - Enable FastISel on ARM for Linux and NaClJF Bastien
This also pulls in a TargetMachine.h change from r176986 and changes NaCl's intrinsics-bitmanip.ll test to account for register spills at O0. FastISel was only enabled for iOS ARM and Thumb2, this patch enables it for ARM (not Thumb2) on Linux and NaCl. 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 test-suite on A15 hardware with --optimize-option=-O0 and all the tests pass.

2013-05-29Apply LLVM upstream: r182175 - Support unaligned load/store on more ARM targetsJF Bastien
This patch matches GCC behavior: the code used to only allow unaligned load/store on ARM for v6+ Darwin, it will now allow unaligned load/store for v6+ Darwin as well as for v7+ on Linux and NaCl. The distinction is made because v6 doesn't guarantee support (but LLVM assumes that Apple controls hardware+kernel and therefore have conformant v6 CPUs), whereas v7 does provide this guarantee (and Linux/NaCl behave sanely). The patch keeps the -arm-strict-align command line option, and adds -arm-no-strict-align. They behave similarly to GCC's -mstrict-align and -mnostrict-align. I originally encountered this discrepancy in FastIsel tests which expect unaligned load/store generation. Overall this should slightly improve performance in most cases because of reduced I$ pressure. R=dschuff@chromium.org Review URL: https://codereview.chromium.org/15677005

The motivation for this is address space 0 global variables are illegal since we cannot declare variables in the generic address space. Instead, we place the variables in address space 1 and explicitly convert the pointer to address space 0.

2013-05-17Re-allow an x86-32 fast-isel optimization for NaCl / use shorter insts.Jan Voung
There was an old fix for r+r based memory references on x86-64 that checked for isTargetNaCl() instead of isTargetNaCl64(). This disabled some r+r for 32-bit. However, fast isel only sets up r+r with geps, and we don't have geps in the stable ABI. We could potentially add some similar pattern matching in the future... The problem we *do* see with the current bitcode, is that this change also made it preferred to use an index register instead of a base register. This made the memory references on x86-32 look like: cmpl ..., (,%eax,1) instead of cmpl ..., (%eax) So we had longer instructions. Total zipped nexe sizes: 5.73MB (old) vs 5.59 MB (new) (2.5%) Total not zipped: 17.28MB vs 16.28 MB (6%) runtime diffs (min of 5 runs) * eon 4.94 (old) vs 4.72 (new) (~4%) * mesa 21.64 vs 21.08 * mcf 5.76 vs 5.60 * vortex 4.21 vs 4.05 * perlbmk 27.62 vs 26.55 (the rest were under 2% better) BUG=https://code.google.com/p/nativeclient/issues/detail?id=3359 R=stichnot@chromium.org Review URL: https://codereview.chromium.org/15047013

This flag is only set by storeRegToStackSlot and loadRegFromStackSlot. spillCalleeSavedRegisters does not call storeRegToStackSlot, but instead produces MI directly. Thus we don't see the CR is spilled when assigning frame offsets, and the CR spill ends up colliding with some other location (generally the FP slot).

2013-05-06[SystemZ] Add back endUlrich Weigand
This adds the actual lib/Target/SystemZ target files necessary to implement the SystemZ target. Note that at this point, the target cannot yet be built since the configure bits are missing. Those will be provided shortly by a follow-on patch. This version of the patch incorporates feedback from reviews by Chris Lattner and Anton Korobeynikov. Thanks to all reviewers!
