I believe the bot failures on linux systems were due to overestimating the
alignment of object-files within archives, which are only guaranteed to be
two-byte aligned. I have reduced the alignment in
RuntimeDyldELF::createObjectImageFromFile accordingly.

Appease the buildbots for targets which do not build the ARM support by moving
the ARM specific test into a subdirectory and use the lit configuration to
disable them appropriately.

Thanks to chapuni and thakis for explaining how to do this!

Operands which involved label arithemetic would previously fail to parse.  This
corrects that by adding the additional case for the shift operand validation.

This adds some preliminary support for decoding ARM EHABI unwinding information.
The major functionality that remains from complete support is bytecode
translation.

Each Unwind Index Table is printed out as a separate entity along with its
section index, name, offset, and entries.

Each entry lists the function address, and if possible, the name, of the
function to which it corresponds.  The encoding model, personality routine or
index, and byte code is also listed.

Fix a bug about generating undef operand when optimising shuffle vector and insert element in instruction combine.

When determining the type of array members, do not see-through typedefs
For instance, in BOOL arr[4], we want the elements to be typed as BOOL, not signed char

particular, the access specifier may be missing if this happens inside a class
definition, due to a violation of an AST invariant).

materialize a variable in a register correctly
if the variable is a pointer.  This fixes a
regression introduced by my commit of Oct. 22nd
(r193191).

Fixed an issue when attaching to a process without specifying a file where we wouldn't set the dyld gdb image notifier breakpoint correctly.

Debug info: Implement a cleaner version of r198461. For symmetry with
C and C++ don't emit an extra lexical scope for the compound statement
that is the body of an Objective-C method.

llvm-svn: 198715

This reverts commit r198461.

llvm-svn: 198714

This reverts commit 198699 so we can get a cleaner patch.

llvm-svn: 198713

- If there is only 1 frame ptr_refs now works (fixed issue with stack detection)
- Fixed test for result now that it isn't a pointer anymore

...even though the argument is declared "const void *", because this is
just a way to pass pointers around as objects. (Though NSData is often
a better one.)

llvm-svn: 198710

RetainCountChecker has to track returned object values to know if they are
retained or not. Under ARC, even methods that return +1 are tracked by the
system and should be treated as +0. However, this effect behaves exactly
like NotOwned(ObjC), i.e. a generic Objective-C method that actually returns
+0, so we don't need a special case for it.

No functionality change.

This makes it available to tools that don't link with target (like llvm-ar).

take type from the new symbol but merge them so that the type
is never "downgraded".

This is probably quite rare, except for IFUNC symbols which
we used to misassemble, losing the IFUNC type.

Fixes #18372.

Updating the documentation about how to add attributes based on the rather extensive refactorings that have happened over the past several months.

In SVN checkouts, clang_revision_tag is rerun on every build, even if nothing
else is dirty.  After this change, Version.inc is only written at cmake time,
so that empty builds run 0 build steps (like r191784 apparently did for git).

always produce as pretty of results as it does in LLVM and Clang, but
I don't mind and the value of having a single canonical ordering is very
high IMO.

Let me know if you spot really serious problems here.

With the gnu objc runtime private strings are used. Since we only need to
produce a unique label, the fix is to just drop the asserts.
