2012-07-02The built-in shell test runner for some reason doesn't like the quotingChandler Carruth
and multi-line nature of this test. I don't really feel like bugging this kind of edge-case, so just put it on one line and use single quotes. With this, every test *really* passes with the built-in shell test runner. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@159530 91177308-0d34-0410-b5e6-96231b3b80d8
2012-07-02Fix the TCL-style quoting in one random test that somehow slippedChandler Carruth
through my perl nets. With this, the test suite passes even if I force it to run with the built-in shell test logic, except for a test which REQUIREs shell. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@159529 91177308-0d34-0410-b5e6-96231b3b80d8

IntegersSubsetMapping - Optimized diff operation. - Replaced type of Items field from std::list with std::map. - Added new methods: bool isOverlapped(self &RHS) void add(self& RHS, SuccessorClass *S) void detachCase(self& NewMapping, SuccessorClass *Succ) void removeCase(SuccessorClass *Succ) SuccessorClass *findSuccessor(const IntTy& Val) const IntTy* getCaseSingleNumber(SuccessorClass *Succ) IntegersSubsetTest - DiffTest: Added checks for successors.

2012-07-02Convert all tests using TCL-style quoting to use shell-style quoting.Chandler Carruth
This was done through the aid of a terrible Perl creation. I will not paste any of the horrors here. Suffice to say, it require multiple staged rounds of replacements, state carried between, and a few nested-construct-parsing hacks that I'm not proud of. It happens, by luck, to be able to deal with all the TCL-quoting patterns in evidence in the LLVM test suite. If anyone is maintaining large out-of-tree test trees, feel free to poke me and I'll send you the steps I used to convert things, as well as answer any painful questions etc. IRC works best for this type of thing I find. Once converted, switch the LLVM lit config to use ShTests the same as Clang. In addition to being able to delete large amounts of Python code from 'lit', this will also simplify the entire test suite and some of lit's architecture. Finally, the test suite runs 33% faster on Linux now. ;] For my 16-hardware-thread (2x 4-core xeon e5520): 36s -> 24s git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@159525 91177308-0d34-0410-b5e6-96231b3b80d8
2012-07-02Make tests which first provide a negative assertion via 'not', thenChandler Carruth
a pipeline, and then a positive assertion via grep, use two RUN lines instead. Supporting these complex ideas of 'success' and 'failure' across multiple stages of a pipeline is brittle in the shell world, and would block switching to ShTest format; it only worked due to contrivances introduced by the TclTest format. Writing this as two separate RUN lines seems clearer in any event. This is another step toward completely removing TclTests from lit. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@159524 91177308-0d34-0410-b5e6-96231b3b80d8
2012-07-02Rewrite three tests that had truly egregious abuses of 'grep' in them toChandler Carruth
use FileCheck. Aside from removing a dependence on TCL-style quoting, this also makes the tests ... significantly more robust. =] It would be really, *really* great of the maintainer(s) of the CellSPU backend went through and systematically rewrite these tests to use FileCheck. There are a lot more that have nearly this bad of abuses. Another step along the path to a TclTest-free testsuite. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@159523 91177308-0d34-0410-b5e6-96231b3b80d8

2012-07-02Switch a bunch of Linker tests from using elaborate echo productions toChandler Carruth
just provide and reference separate input files from an Inputs subdirectory. This pattern works very well in the Clang tree and is easier to understand in my opinion. It also has fewer limitations and will remove one particularly annoying use of TCL-style {} quoting from the testsuite. Also teach the LLVM lit configuration to avoid recursing into 'Inputs' subdirectories. This wasn't required for the previous 'Inputs' subdirectories used due to fortuitous suffix patterns. This is the first step to completely removing support for TCL-style tests. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@159520 91177308-0d34-0410-b5e6-96231b3b80d8

2012-06-29Move llvm/Support/IRBuilder.h -> llvm/IRBuilder.hChandler Carruth
This was always part of the VMCore library out of necessity -- it deals entirely in the IR. The .cpp file in fact was already part of the VMCore library. This is just a mechanical move. I've tried to go through and re-apply the coding standard's preferred header sort, but at 40-ish files, I may have gotten some wrong. Please let me know if so. I'll be committing the corresponding updates to Clang and Polly, and Duncan has DragonEgg.

2012-06-29Make NumMicroOps a variable in the subtarget's instruction itinerary.Andrew Trick
The TargetInstrInfo::getNumMicroOps API does not change, but soon it will be used by MachineScheduler. Now each subtarget can specify the number of micro-ops per itinerary class. For ARM, this is currently always dynamic (-1), because it is used for load/store multiple which depends on the number of register operands. Zero is now a valid number of micro-ops. This can be used for nop pseudo-instructions or instructions that the hardware can squash during dispatch. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@159406 91177308-0d34-0410-b5e6-96231b3b80d8
