in the abstraction for lit test suites so that the various other layers
of abstraction pick up the same behavioral fix, and so that we still get
a complete list of dependencies for the 'check-all' target.

This should fix the follow-on issues of the same nature with various
other build targets, including Clang targets. Sorry for the churn, and
again thanks to Matt for testing and breaking this more thoroughly.

No functionality changed here, except that the CMake installed by
default on Ubuntu Lucid should actually work with the makefile
generators now.

Thanks to Matt for the report and head-desking required to figure out
why it was failing.

'|&' bash syntax. We have lots of users with a bash on their system
which doesn't support this syntax, and as bash is still significantly
faster, we should support them.

The test suite has already been updated to cope with this.

within the LLVM CMake build.

This is still a work in progress but I believe it is currently good enough
to fix PR13122 "Need unit test driver for codegen IR passes".  For example,
you can run llc with -stop-after=loop-reduce to have it dump out the IR after
running LSR.  Serializing machine-level IR is not yet supported but we have
some patches in progress for that.

The plan is to serialize the IR to a YAML file, containing separate sections
for the LLVM IR, machine-level IR, and whatever other info is needed.  Chad
suggested that we stash the stop-after pass in the YAML file and use that
instead of the start-after option to figure out where to restart the
compilation.  I think that's a great idea, but since it's not implemented yet
I put the -start-after option into this patch for testing purposes.

This makes it possible to just use a zero value to represent "no pass", so
the phony NoPassID global variable is no longer needed.

This is a preliminary step toward having TargetPassConfig be able to
start and stop the compilation at specified passes for unit testing
and debugging.  No functionality change.

My last checkin was apparently not the branch I intended. It was missing one change (added by chandlerc), and contained a spurious change.

llvm-svn: 159548

another mechanical change accomplished though the power of terrible Perl
scripts.

I have manually switched some "s to 's to make escaping simpler.

While I started this to fix tests that aren't run in all configurations,
the massive number of tests is due to a really frustrating fragility of
our testing infrastructure: things like 'grep -v', 'not grep', and
'expected failures' can mask broken tests all too easily.

Essentially, I'm deeply disturbed that I can change the testsuite so
radically without causing any change in results for most platforms. =/

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.

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.

This is directly cloned from the logic in the TCL test bits of lit.
Hopefully will fix most of the windows build bot fallout.

  - Changed isSingleNumber method behaviour. Now this flag is calculated on demand.
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.
SimplifyCFG
  Updated SwitchInst usage (now it is case-ragnes compatible) for
    - SimplifyEqualityComparisonWithOnlyPredecessor
    - FoldValueComparisonIntoPredecessors

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. ;]

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.

llvm-svn: 159524

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.

llvm-svn: 159523

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.

1) DIContext is now able to return function name for a given instruction address (besides file/line info).
2) llvm-dwarfdump accepts flag --functions that prints the function name (if address is specified by --address flag).
