Put a limit on ScheduleDAGSDNodes::ClusterNeighboringLoads to avoid blowing up compile time.

Fixes PR16365 - Extremely slow compilation in -O1 and -O2.

The SD scheduler has a quadratic implementation of load clustering
which absolutely blows up compile time for large blocks with constant
pool loads. The MI scheduler has a better implementation of load
clustering. However, we have not done the work yet to completely
eliminate the SD scheduler. Some benchmarks still seem to benefit from
early load clustering, although maybe by chance.

As an intermediate term fix, I just put a nice limit on the number of
DAG users to search before finding a match. With this limit there are no
binary differences in the LLVM test suite, and the PR16365 test case

10 years agoChanges in IntelJITEventListener - By Arch Robinson

Changes in IntelJITEventListener - By Arch Robinson
   - take->release: LLVM has moved to C++11.  MockWrapper became an instance of unique_ptr.

   - method symbol_iterator::increment disappeared recently, in this revision:

     r200442 | rafael | 2014-01-29 20:49:50 -0600 (Wed, 29 Jan 2014) | 9 lines

Simplify the handling of iterators in ObjectFile.

None of the object file formats reported error on iterator increment. In
retrospect, that is not too surprising: no object format stores symbols or
sections in a linked list or other structure that requires chasing pointers.
As a consequence, all error checking can be done on begin() and end().

This reduces the text segment of bin/llvm-readobj in my machine from 521233 to
518526 bytes.

My change mimics the change that the revision made to lib/DebugInfo/DWARFContext.cpp .

    - const_cast: Shut up a warning from gcc.

I ran unittests/ExecutionEngine/JIT/Debug+Asserts/JITTests to make sure it worked.

ARM: consolidate MachO checks for ARM asm parser

This consolidates the duplicated MachO checks in the directive parsing for
various directives that are unsupported for Mach-O.  The error message change is
unimportant as this restores the behaviour to that prior to the addition of the
new directive handling.  Furthermore, use a more direct check for MachO
targeting rather than an indirect feature check of the assembler.

Also simplify the test execution command to avoid temporary files.  Further more,
perform the check in both object and assembly emission.

Whether all non-applicable directives are handled is another question.  .fnstart
is marked as being unsupported, however, the complementary .fnend is not.  The
additional unwinding directives are also still honoured.  This change does not
change that, though, it would be good to validate and mark them as being
