Change the fast-isel-abort option from bool to int to enable "levels" Summary: Currently fast-isel-abort will only abort for regular instructions, and just warn for function calls, terminators, function arguments. There is already fast-isel-abort-args but nothing for calls and terminators. This change turns the fast-isel-abort options into an integer option, so that multiple levels of strictness can be defined. This will help no being surprised when the "abort" option indeed does not abort, and enables the possibility to write test that verifies that no intrinsics are forgotten by fast-isel.

ARM MachO: sort out isTargetDarwin/isTargetIOS/... checks. The ARM backend has been using most of the MachO related subtarget checks almost interchangeably, and since the only target it's had to run on has been IOS (which is all three of MachO, Darwin and IOS) it's worked out OK so far. But we'd like to support embedded targets under the "*-*-none-macho" triple, which means everything starts falling apart and inconsistent behaviours emerge. This patch should pick a reasonably sensible set of behaviours for the new triple (and any others that come along, with luck). Some choices were debatable (notably FP == r7 or r11), but we can revisit those later when deficiencies become apparent. llvm-svn: 198617

Enable FastISel on ARM for Linux and NaCl, not MCJIT 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. llvm-svn: 183966

Mass update to CodeGen tests to use CHECK-LABEL for labels corresponding to function definitions for more informative error messages. No functionality change and all updated tests passed locally. This update was done with the following bash script: find test/CodeGen -name "*.ll" | \ while read NAME; do echo "$NAME" if ! grep -q "^; *RUN: *llc.*debug" $NAME; then TEMP=`mktemp -t temp` cp $NAME $TEMP sed -n "s/^define [^@]*@\([A-Za-z0-9_]*\)(.*$/\1/p" < $NAME | \ while read FUNC; do sed -i '' "s/;\(.*\)\([A-Za-z0-9_-]*\):\( *\)$FUNC: *\$/;\1\2-LABEL:\3$FUNC:/g" $TEMP done sed -i '' "s/;\(.*\)-LABEL-LABEL:/;\1-LABEL:/" $TEMP sed -i '' "s/;\(.*\)-NEXT-LABEL:/;\1-NEXT:/" $TEMP sed -i '' "s/;\(.*\)-NOT-LABEL:/;\1-NOT:/" $TEMP sed -i '' "s/;\(.*\)-DAG-LABEL:/;\1-DAG:/" $TEMP mv $TEMP $NAME fi done llvm-svn: 186280
