Summary:
Convert tests using LLDB headers to use generateSource to put the right include paths in place regardless of whether or not you're building a framework.
This also abstracted generateSource out of TestPublicAPIHeaders.py into lldbtest.py.

Summary:
Check whether the setting the breakpoint failed during instruction emulation. If
it did, the next pc is likely in unmapped memory, and the inferior will crash
anyway after the next instruction. Do not return an error in this case, but just
continue stepping.
Reenabled the crash during step test for android/linux.

They already contain the same test name in the directory, file, and class names,

The "value regs" field was filled incorrectly. It is supposed to list the
registers that *this* register is a sub-register of, not the other way around.
This manifested itself in "register read" showing only the smaller sub-registers
(and a bunch of tests not passing). I am not sure if the "invalidates" field is
correct either, but it's usage seems to be inconsistent, so I'll leave that as-is
for now.

It's quite sad that we have to edit so many files just to add a register. I am
going to investigate how to merge these definitions somehow, but for now this

This tests that lldb handles the situation when a single instruction triggers
multiple watchpoint hits. It currently fails on arm due to what appears to be a
lldb-server bug (pr30758).
llvm-svn: 284819
This reverts commit r284795, as it breaks watchpoint handling on arm (and
presumable all architectures that report watchpoint hits without executing the
tripping instruction).
There seems to be something fundamentally wrong with this patch: it uses
process_sp->AddPreResumeAction to re-enable the watchpoint, but the whole point
of the step-over-watchpoint logic (which AFAIK is the only user of this class) is
to disable the watchpoint *after* we resume to do the single step.
I have no idea how to fix this except by reverting the offending patch.

This can happen if you debug an iOS corefile on

Also, watchpoint commands, like breakpoint commands, need to run in async mode.
This was causing intermittent failures in TestWatchpointCommandPython.py, which is now solid.

This time it should actually work. The previous implementaiton was not
getting the linker or compiler flag set correctly in all the right
situations. By moving the check down and basing it of whether or not CXX
is set I we can have the logic to add the flags exist only once for the
linker and once for the compiler instead of duplicating it.

Summary:
I misunderstood the format of the register context layout.
I thought it was a dynamically changing structure, and that it's size
depended on context_flags.
It turned out that it always has the same fixed layout and size,
and the context_flags says which fields of the
struct have valid values.
This required a minor redesign of the register context class.
The layout inconsistency, however, was not a "problem" before (e.g. the plugin was working)
because there also was a bug with checking context_flags - the code was
parsing the entire struct regardless of context_flags.
This bug is also fixed in this commit.

RegisterInfos_arm64.h. These register definitions include the
offset into the register context, which will vary depending on the
endianness of the arm64 target system (e.g. s8 is at offset 0 in
v8 on little-endian, it is at offset 12 on big-endian) and I've
only added the little-endian definitions to the table. If we want
to add a big-endian arm64 target, we'll need a separate table which
uses the big-endian offsets for these registers. I changed the
name of the register table from g_register_infos_arm64 to
g_register_infos_arm64_le to make it explicit that this is the
little-endian version of that table, and updated users of the table
to use the new name.
I added support for the "w", "s", and "d" registers to
RegisterContextDarwin_arm64 but it was more an example than anything
useful -- this plugin is only used when working with core files and
darwin core files do not (today) include the floating point register
context, so it only added the support for the "w" pseudo registers.
When we're connected to a real arm64 device, we use the ProcessGDBRemote
code.

"Initialization of function-local statics is guaranteed to occur only once even when called from

Summary:
Now the Minidump parser can parse the:
1) MemoryInfoList - containing region info about memory ranges (readable,
writable, executable)
2) Memory64List - this is the stuct used when the Minidump is a
full-memory one.
3) Adding filtering of the module list (shared libraries list) - there
can be mutliple records in the module list under the same name but with
different load address (e.g. when the binary has non contigious
sections). FilterModuleList eliminates the duplicated modules, leaving
the one with the lowest load addr.
Added unit tests for everything.

Summary:
If a user has their shell set to a non-POSIX conferment shell the TestTerminal.py tests fail because the shell blurb constructed here may not work in their shell.
In my specific case fish-shell (The Friendly Interactive Shell - http://fishshell.com) does not support $?, it instead uses $status (because it is friendly).
This patch removes the assumption of your default shell by running the constructed bash command via "/bin/bash -c ...". This should be safer for users mutating their shell environment.

Summary:
CMake has no builtin mechanism for cache invalidation. As a general convention you want to not expand user-specified variables in other cached variables because they will not get updated when the user changes their specified value.
This patch moves the "-C" option for dotest.py into the LLDB_TEST_COMMON_ARGS and out of the CMake cache. In order to prevent issues with out-of-date cache files on builders I've added code to scrub "-C ${LLDB_TEST_COMPILER}" out of the CMake caches, by Force writing the variable. This code can be removed in a few days once the change has trickled through CI systems.

Summary:
When building the LLDB test programs, if your CC is clang it actually isn't safe to make CXX a string replace of "clang -> clang++". This falls down on unix configurations if your compiler is clang-${version}.
A safer approach is to use the "--driver-mode=g++" option to tell clang to act like clang++.
