output style can be customized. Change the built-in default to be
more similar to gdb's disassembly formatting.
The disassembly-format for a gdb-like output is
${addr-file-or-load} <${function.name-without-args}${function.concrete-only-addr-offset-no-padding}>:
The disassembly-format for the lldb style output is
{${function.initial-function}{${module.file.basename}`}{${function.name-without-args}}:\n}{${function.changed}\n{${module.file.basename}`}{${function.name-without-args}}:\n}{${current-pc-arrow} }{${addr-file-or-load}}:
The two backticks in the lldb style formatter triggers the sub-expression evaluation in
CommandInterpreter::PreprocessCommand() so you can't use that one as-is ... changing to
use ' characters instead of ` would work around that.

Since these tests pass on (at least some) other platforms, change the
decorators to @expectedFailureDwarwin. Tested on FreeBSD with Clang 3.4
and libc++.

Perhaps these should be @expectedFailureDarwin instead of
@unittest2.expectedFailure (applying to all hosts); I'm not aware of
the details in the rdars.
Just add a comment for now, for the benefit of anyone investigating
FreeBSD test issues in the future.

Fixes http://llvm.org/bugs/show_bug.cgi?id=18656.
Note this exposes a failure on Linux of
TestInferiorAssert.test_inferior_asserting_disassemble, similar to how
it fails on FreeBSD. I'll file a bug for this next. We're now getting
another frame beyond where we used to prior to this fix, so the fix is
exposing failures in previosly not-reachable frames.
Much thanks to Jason Molenda, who had much to do with helping figure
out where unwinding was breaking.

This has led to many test suite failures because of copy and paste where new test cases were based off of other test cases and the "mydir" variable wasn't updated.
Now you can call your superclasses "compute_mydir()" function with "__file__" as the sole argument and the relative path will be computed for you.

to build out the symbol table as addresses are used, and implements
the mechanism for ELF to add stripped symbols from eh_frame.
Uses this mechanism to allow disassembly for addresses corresponding
to stripped symbols for ELF, and provide hooks to implement this for
PE COFF.
Also removes eSymbolContextTailCall in favor of an option for
ResolveSymbolContextForAddress for consistency with the documentation
for eSymbolContextEverything. Essentially, this is just an option for
interpreting the so_addr.
llvm-svn: 191307
Specifically, allows the unwinder to handle the case where sc.function
gets resolved with a pc that is one past the address range of the function
(consistent with a tail call). However, there is no matching symbol.
Adds eSymbolContextTailCall to provide callers with control over the scope
of symbol resolution and to allow ResolveSymbolContextForAddress to handle
tail calls since this routine is common to unwind and disassembly.

and -fomit-frame-pointer.
- Parses eh_frame FDEs to determine the function address and size so that
the call frame parsing can continue.
Note: This code path is specific to ELF and PECOFF, because ObjectFileMachO
uses LCT_FunctionStarts to efficiently populate the symbol table.
Thanks to Jason Molenda for the review!

- Note that this is not correct, as the failure is associated with build options of libc.so, however it's failing on a Debian buildbot that uses gcc 4.6.2 (and the real goal is a complete backtrace even with -fomit-frame-pointer).
- Adds helpers to lldbtest.py to check the expectedCompiler and expectedVersion, with an eventual goal of reducing the number of test decorators.
--- Currently allows a comparison operator and a compiler version to be specified.
--- Can be extended to support ranges of compiler versions.
llvm-svn: 182155
- On Linux, the partial back-trace after an assert can cause the basic test to fail as discussed on lldb-dev.
- Uses SBFrame to walk up the stack to the assert site and tests expression evaluation of locals, globals and arguments.
Thanks to Daniel for review and testing on OS/X.
