Added function for removing relative operators from input paths.

the extra check introduces 22 new test failures with the LLDB clang buildbot.

Note that the unhandled DWARF_OP codes in DWARFExpression::Evaluate don't cause test failures if the check is ignored.

The heuristic that merges register pressure sets was bogus for ARM's S/D regs.

Changed register names (and pointer keywords) to be lower case when using Intel X86 assembler syntax.

This fix is very lightweight. The same fix already existed for AddRec
but was missing for NAry expressions.

This is obviously an improvement and I'm unsure how to test compile
time problems.

list have a shared pointer back to their DisassemblerLLVMC.  This checkin force clears the InstructionList
in all the places we use the DisassemblerSP to stop the leaking for now.  I'll go back and fix this
for real when I have time to do so.

For a testcase like the following:

 typedef unsigned long uint64_t;

 typedef struct {
   uint64_t lo;
   uint64_t hi;
 } blob128_t;

 void add_128_to_128(const blob128_t *in, blob128_t *res) {
   asm ("PAND %1, %0" : "+Q"(*res) : "Q"(*in));
 }

where we'll fail to allocate the register for the output constraint,
our matching input constraint will not find a register to match,
and could try to search past the end of the current operands array.

On the idea that we'd like to attempt to keep compilation going
to find more errors in the module, change the error cases when
we're visiting inline asm IR to return immediately and avoid
trying to create a node in the DAG. This leaves us with only
a single error message per inline asm instruction, but allows us
to safely keep going in the general case.

Clang when linking and using a GCC installation from a GCC
cross-compiler.

This was desired already by two special case platforms (Android and
Mips), and turns out to be generally (if frustratingly) true. I've added
a substantial comment to the code clarifying the underlying assumptions
of doing actual cross compiles with Clang (or GCC for that matter!) and
help avoid further confusion here.

The end result is to realize that fully general form of PR12478 cannot
be resolved while we support existing cross-compiling GCC toolchains,
and linking with them (namely, linking against their libgcc and
libstdc++ installs). GCC installs these target libraries under
a target-specific prefix but one that may not be available within the
actual sysroot in use. When linking in this world, GCC works and Clang
should as well, but caveat emptor: DSOs from this tree must be
replicated and rpath-fixed to be found at runtime within the sysroot.

I've extended the cross compile test cases to cover these issues by
pointing them at a sysroot and actually checking the library search
paths.

One form would accept a vector of pointers, and the other did not.
Make both accept vectors of pointers, and add an assertion
for the number of elements.

The unix one was returning no_such_file_or_directory, but the windows one
was return success.

Update the one one caller that was depending on the old behavior.

This avoids constant folding bitcast/ptrtoint/inttoptr combinations
that have illegal bitcasts between differently sized address spaces.

Apparently dragonegg uses it.

The BSS atom is similar to the regular defined atom, but it's different
in the sense that it does not have contents. Until now we assumed all the
defined atoms have its contents. That did not fit well to the BSS atom.

In limited testing this seems to work. Caveat emptor.

llvm-svn: 187452

- disable some TestConcurrentEvents cases (which are affected by llvm.org/pr16714 -- watchpoints in multithreaded programs)
- relax number-of-bp-locations check in TestUniqueTypes/TestUnsignedTypes
- skip TestDataFormatterStdVector cases with GCC 4.8 (known failure due to llvm.org/pr15301)
- workaround for race condition in TestHelloWorld.py
- update TestSettings.py to work on distros (like Fedora) that have /bin/cat hardlinked to /usr/bin/cat

After these changes, the test suite should run cleanly against GCC 4.8 (with DWARF v4)!

llvm-svn: 187451

- pass through to base-class implementation when raised exception is not from an LLDBTest
- should make the test suite errors a little easier to root-cause

llvm-svn: 187450

- better than failing silently next time the DWARF standard introduces new opcodes!

Debug mode for unordered_multimap.  Some mods were done for unordered_map as well to keep all the tests passing.  However unordered_map is at the very least still missing tests, if not functionality (if it isn't tested, it probably isn't working).

llvm-svn: 187446

Call into ComputeMaskedBits to figure out which bits are set on both add
operands and determine if the value is a power-of-two-or-zero or not.

llvm-svn: 187445

It will now only convert the arguments / return value and call
the underlying function if the types are able to be bitcasted.
This avoids using fp<->int conversions that would occur before.
