According to "Addenda to ABI for ARM architecture", Tag_FP_arch is the
new name for the equivalent Tag_VFP_arch.  This commit renames
Tag_VFP_arch to Tag_FP_arch.

I am about to send a patch for review touching these and clang-formating first
makes the patch much easier to read.

llvm-svn: 197585

Implement the MSABI and SysVABI calling conventions for Objective-C method declarations. This appears to be an omission from r189644.

llvm-svn: 197584

I will introduce another flag, like --system-libs, later.

llvm-svn: 197583

Adding some comments about AST node requirements for attributes which create AST nodes but never actually make use of them. No functional changes.

During testing I observed QEMU send "$T02thread:01;#04" upon connection,
before any command from LLDB.  This change from gclayton accepts (and
discards) a packet immediately after sending the initial ack, to flush
the GDB remote pipeline.

This commit kills off custom type specifier and keyword handling of OpenCL C
data types.

Although the OpenCL spec describes them as keywords, we can handle them more
elegantly as predefined types. This should provide better error correction and
code completion as well as simplifying the implementation.

The primary intention is however to simplify the C/C++ parser and save some
packed bits on AST structures that had been extended in r170432 just for
OpenCL.

A f64 inside a struct can be 32 bit aligned on darwin.

llvm-svn: 197575

This patch adds -f64:32:64 to 32 bit ppc darwin since a f64 inside a
structure are only 32 bit aligned.

The patch also drop -f128:64:128 from all ppc darwin, since f128 is
128 bit aligned.

Thanks for Iain Sandoe for testing this with the original gcc.

Clang was already getting this right.

This code is not robust enough and triggers when simply linking with
libdynamorio.so, without any code translation at all. Disabling it is safe
(i.e. we may unpoison too much memory and see false negatives, but never false
positives).

The polly on-commit formatting checker notified me that I forgot to format
the code before submitting.

We now report the following:

Before:
  aaaaaaaaaa(aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa(
      aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa)
                 .aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa);
  aaaaaaaaaa = aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa(
      aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa)
                   .aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa();

After:
  aaaaaaaaaa(aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa(
                 aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa)
                 .aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa);
  aaaaaaaaaa = aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa(
                   aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa)
                   .aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa();

Probably still not ideal, but should be a step into the right direction.

This should fix the ARM bots.

Clang sets the float-abi target option manually, but no longer
annotates each function with its ABI. This can lead to confusing
mistmatch between "clang -emit-llvm | llc" and normal clang
invocations.

Besides which, gnueabihf actually *is* hard-float. Defaulting to soft
was just perverse.

Before:
  bool a = ([aaaaaaaa aaaaa] == aaaaaaaaaaaaaaaaa || [aaaaaaaa aaaaa] ==
                                                         aaaaaaaaaaaaaaaaaaaa);

After:
  bool a = ([aaaaaaaa aaaaa] == aaaaaaaaaaaaaaaaa ||
            [aaaaaaaa aaaaa] == aaaaaaaaaaaaaaaaaaaa);

This fixes llvm.org/PR18271.

Right now clang produces the same DataLayout for all of them, but it could, for
example, add 'n' specifications when the end architecture is given.

No functionality change, this should just make future changes easier to read.

llvm-svn: 197549

No functionality change.

The .end directive indicates the end of the file.  No further instructions are
processed after a .end directive is encountered.

One potential (glaringly obvious) optimisation that could be pursued here is to
extend MCAsmParser with a DiscardRemainder method to avoid processing lexemes to
the end of the file.  It was unclear at this point if that would be worth
adding, and could easily be added in a follow on change.

Fixed a crasher that would only occur if Xcode attaches to a remote process first, then launches.
