* 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

* [PowerPC] Disable fast-isel for existing -O0 tests for PowerPC.Bill Schmidt2013-06-13
| | | | | | | | | | | | | | | | | | | | | | | | | This is a preliminary patch for fast instruction selection on PowerPC. Code generation can differ between DAG isel and fast isel. Existing tests that specify -O0 were written to expect DAG isel. Make this explicit by adding -fast-isel=false to the tests. In some cases specifying -fast-isel=false produces different code even when there isn't a fast instruction selector specified. This is because TM.Options.EnableFastISel = 1 at -O0 whether or not a FastISel object exists. Thus disabling fast isel can actually produce less conservative code. Because of this, some of the expected code generation in the -O0 tests needs to be adjusted. In particular, handling of function arguments is less conservative with -fast-isel=false (see isOnlyUsedInEntryBlock() in SelectionDAGBuilder.cpp). This results in fewer stack accesses and, in some cases, reduced stack size as uselessly loaded values are no longer stored back to spill locations in the stack. No functional change with this patch; test case adjustments only. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@183939 91177308-0d34-0410-b5e6-96231b3b80d8

* Fix DeleteDeadVarargs not to crash on functions referenced by BlockAddressesDerek Schuff2013-06-13
| | | | | | | | | | | | | | | This pass was assuming that if hasAddressTaken() returns false for a function, the function's only uses are call sites. That's not true because there can be references by BlockAddresses too. Fix the pass to handle this case. Fix BlockAddress::replaceUsesOfWithOnConstant() to allow a function's type to be changed by RAUW'ing the function with a bitcast of the recreated function.
