The GNU assembler supports prefixing the expression with a '#' to indiciate that
the value that is being moved is infact a constant.  This improves the
compatibility of the integrated assembler's parser for this.

llvm-svn: 198916

The GNU assembler has an extension that allows for the elision of the paired
register (dt2) for the LDRD and STRD mnemonics.  Add support for this in the
assembly parser.  Canonicalise the usage during the instruction parsing from
the specified version.

llvm-svn: 198915

The ARM ARM indicates the mnemonics as follows:

  ldrbt{<c>}{<q>} <Rt>, [<Rn>], {, #+/-<imm>}
  ldrt{<c>}{<q>} <Rt>, [<Rn>] {, #+/-<imm>}
  strbt{<c>}{<q>} <Rt>, [<Rn>] {, #<imm>}
  strt{<c>}{<q>} <Rt>, [<Rn>] {, #+/-<imm>}

This improves the parser to deal with the implicit immediate 0 for the mnemonics
as per the specification.

Thanks to Joerg Sonnenberger for the tests!

[Sparc] Emit retl/ret instead of jmp instruction. It improves the readability of the assembly generated.

[Sparc] Add support for parsing jmpl instruction and make indirect call and jmp instructions as aliases to jmpl.

This reverts commit r198865 which reverts r198851.

ASan identified a use-of-uninitialized of the DwarfTypeUnit::Ty variable
in skeleton type units.

__declspec(align), when applied to bitfields affects their perferred 
alignment instead of their required alignment.  We don't know why.  
Also, #pragma pack(n) turns packing *off* if n is greater than the 
pointer size.  This is now observable because of the impact of 
declspec(align) on bitfields.

Original commit message:

PR18427: Use an appropriately-aligned buffer in APValue, to avoid a crash on
SPARC, where uint64_t apparently requires higher alignment than void*.

I previously fixed a bug in the SocketAddress class where SocketAddress::GetPort() wasn't using ntohs() on the port number in the structures.

After fixing this, it broke places where we weren't using ntohs() and htons() correctly.

contributors to submit patches to the LLVM project. Thanks to Danny,
Chris, Alp, and others for reviewing.

The MS abi lays out *all* non-virtual bases with leading vfptrs before 
laying out non-virutal bases without vfptrs.  This guarantees that the 
primary base is laid out first.  r198818 fixed RecordLayoutBuilder to 
produce compatiable layouts.  This patch fixes CGRecordLayoutBuilder to 
be able to consume those layouts and produce meaningful output without 
tripping any asserts about assumed incoming layout.

A test case is included that shows CGRecordLayoutBuilder in fact 
produces output in the compatiable order.

__has_attribute now understands target-specific attributes. So when you ask whether an ARM target has the "interrupt" attribute, it will return true for ARM and MSP430 targets, and false for others.

llvm-svn: 198897

Removing the notion of TargetAttributesSema and replacing it with one where the parsed attributes are responsible for knowing their target-specific nature, instead of letting Sema figure it out. This is necessary so that __has_attribute can eventually determine whether a parsed attribute applies to the given target or not.

I introduced this bug in 198815. Thanks for Mark Lacey for noticing.
Unfortunately, I have no idea how to test this code.

Fixes <rdar://problem/15596883>

In ARC, __attribute__((objc_precise_lifetime)) guarantees that the
object stored in it will survive to the end of the variable's formal
lifetime.  It is therefore useful even if it completely unused.

I would not normally add tests like these, but the copy constructor is not
used at all in our codebase with c++11, so having this tests might prevent
breaking the c++03 build again.

To declare or define reserved identifers is undefined behaviour in standard
C++. This needs to be addressed in compiler-rt before it can be used in LLVM.
