NAKAMURA Takumi bac0d769cd raw_ostream: [PR6745] Tweak formatting (double)%e for Windows hosts.
On MSVCRT and compatible, output of %e is incompatible to Posix by default. Number of exponent digits should be at least 2. "%+03d"

FIXME: Implement our formatter in future!

NAKAMURA Takumi 5850225f52 lit/TestingConfig.py: Add the environment variable PRINTF_EXPONENT_DIGITS as workaround [PR6745] for mingw's tests. Danil Malyshev suggested this.
FIXME: It does not improve MSVC's issue.

[Danil Malyshev] Defining PRINTF_EXPONENT_DIGITS env is the suggested way to make MinGW ANSI/POSIX compatible. This is not only about the case we are discussing, but in general, I'd like to have explicitly defined compatibility mode for all the tests running on MinGW.

Daniel Dunbar a9dd1998cc lit: Fix a subtle resource usage bug when executing tests using the internal
shell runner.

We would inadvertently end up holding on to handles to the temporary files
longer than we should have been. On Win32, where open handles lock some file
operations, this caused problems in tests which would try to move temporary
files around (as Clang does by default now).

Many thanks to Francois Pichet for the excellent detective work on this.

Jeffrey Yasskin fa22878d9d Avoid a problem in libc_freeres() seen on a linux-i686 buildbot when running
under valgrind:

==19577== Invalid free() / delete / delete[]
==19577==    at 0x4C9C866: free (vg_replace_malloc.c:325)
==19577==    by 0x5121104: ??? (in /lib/libc-2.10.2.so)
==19577==    by 0x4C97412: _vgnU_freeres (vg_preloaded.c:62)
==19577==    by 0x5041486: __run_exit_handlers (exit.c:93)
==19577==    by 0x50414FE: exit (exit.c:100)
==19577==    by 0x5028B5C: (below main) (libc-start.c:254)
==19577==  Address 0xffffffff is not stack'd, malloc'd or (recently) free'd
==19577== 

Apparently this happens under certain versions of glibc, so valgrind provides
the --run-libc-freeres=no option to avoid calling freeres().  This may increase
the number of "still reachable" blocks valgrind reports, but we don't care
about those, while this error breaks the buildbots.

There are upstream bugs about this at
http://sourceware.org/bugzilla/show_bug.cgi?id=10610 and
http://bugs.kde.org/show_bug.cgi?id=167483, but they don't look likely to be
fixed.

John McCall d423572e86 Teach lit to honor conditional directives. The syntax is:
IF(condition(value)):
If the value satisfies the condition, the line is processed by lit;  otherwise
it is skipped.  A test with no unignored directives is resolved as Unsupported.

The test suite is responsible for defining conditions;  conditions are unary
functions over strings.  I've defined two conditions in the LLVM test suite,
TARGET (with values like those in TARGETS_TO_BUILD) and BINDING (with values
like those in llvm_bindings).  So for example you can write:
  IF(BINDING(ocaml)): RUN: %blah %s -o -
and the RUN line will only execute if LLVM was configured with the ocaml
bindings.

Jeffrey Yasskin 10d3604a9e Make X86-64 in the Large model always emit 64-bit calls.
The large code model is documented at
http://www.x86-64.org/documentation/abi.pdf and says that calls should
assume their target doesn't live within the 32-bit pc-relative offset
that fits in the call instruction.

To do this, we turn off the global-address->target-global-address
conversion in X86TargetLowering::LowerCall(). The first attempt at
this broke the lazy JIT because it can separate the movabs(imm->reg)
from the actual call instruction. The lazy JIT receives the address of
the movabs as a relocation and needs to record the return address from
the call; and then when that call happens, it needs to patch the
movabs with the newly-compiled target. We could thread the call
instruction into the relocation and record the movabs<->call mapping
explicitly, but that seems to require at least as much new
complication in the code generator as this change.

To fix this, we make lazy functions _always_ go through a call
stub. You'd think we'd only have to force lazy calls through a stub on
difficult platforms, but that turns out to break indirect calls
through a function pointer. The right fix for that is to distinguish
between calls and address-of operations on uncompiled functions, but
that's complex enough to leave for someone else to do.

Another attempt at this defined a new CALL64i pseudo-instruction,
which expanded to a 2-instruction sequence in the assembly output and
was special-cased in the X86CodeEmitter's emitInstruction()
function. That broke indirect calls in the same way as above.

This patch also removes a hack forcing Darwin to the small code model.
Without far-call-stubs, the small code model requires things of the
JITMemoryManager that the DefaultJITMemoryManager can't provide.

Thanks to echristo for lots of testing!

Jeffrey Yasskin 35ec32d397 Support GoogleTest's "typed tests"
(http://code.google.com/p/googletest/wiki/GoogleTestAdvancedGuide#Typed_Tests)
in lit.py.  These tests have names like "ValueMapTest/0.Iteration", which broke
when lit.py os.path.join()ed them onto the path and then assumed it could
os.path.split() them back off.  This patch shifts path components from the
testPath to the testName until the testPath exists.

Daniel Dunbar 99e1174baf lit: When executing shell scripts internally, don't allow piped stderr on any
commands except the last one, instead redirect the stderr to a temporary
file. This sidesteps a potential deadlocking issue.

Daniel Dunbar 4c7b0ca05b Add a magic LLVM_DISABLE_CRT_DEBUG environment variable which we check in RegisterHandler and use to disable the Win32 crash dialogs. These are a major blocker to any kind of automated testing.
Also, tweak the 'lit' test runner to set this variable unconditionally.
