When assembling, a .thumb_func directive is supposed to be applicable to the
next symbol definition, even if there are intervening directives. We were
racing ahead to try and find it, and this commit should fix the issue.

some tests test libc/filesystem error handling paths (e.g. close(INT_MAX)),
currently such tests fail
with this change they work as expected

llvm-svn: 193400

There's a barrier instruction so that should still be used, but most actual
atomic operations are going to need a platform decision on the correct
behaviour (either nop if single-threaded or OS-support otherwise).

llvm-svn: 193399

ARM processors without ldrex/strex need to be able to make libcalls for all
atomic operations, including the newer min/max versions.

The alternative would probably be expanding these operations in terms of
cmpxchg (as x86 does always), but in the configurations where this matters
code-size tends to be paramount so the libcall is more desirable.

llvm-svn: 193398

We would previously not diagnose this which would lead to crashes (on
very strange code).

This fixes PR17675.

A TableGen indeterminacy means that the reason for the failure can
vary, and Windows gets the other option.

llvm-svn: 193394

This optimization is not SSE specific so I am moving it to DAGco.
The new scalar_to_vector dag node exposed a missing pattern in the AArch64 target that I needed to add.

__ARM_ARCH_EXT_IDIV__ is the define that ARM is using to indicate the presence
of hardware integer divide (sdiv/udiv). Previously, this code was only being
invoked for processors marked 7S. We now can correctly generate hardware
divides on cortex-a15 devices.

llvm-cov will now be able to read program counts from the GCDA file and
output it in the same format as gcov. The program summary tag was
identified from gcov-io.h as "\0\0\0\a3".

There is currently a bug in GCOVProfiling.cpp which does not generate
the
run- or program-counting IR, so this change was tested manually by
modifying the GCDA file and comparing the gcov and llvm-cov outputs.

llvm-svn: 193389

Without this patch we would warn and fail to output the function in the test.

llvm-svn: 193388

llvm-svn: 193387

Change the uninitialized field warnings so that field initializers are checked
inside the constructor.  Previously, in class initializers were checked
separately.  Running one set of checks also simplifies the logic for preventing
duplicate warnings.  Added new checks to warn when an uninitialized field is
used in base class initialization.  Also fixed misspelling of uninitialized
and moved all code for this warning together.

Refactor: Extract specializing the generic lambda call operator during conversion to fptr deduction into its own function.

No functionality change.

All clang regression tests pass.

Thanks!

Make sure we're predicating right based on CPU even if the triple is 'wrong'.

llvm-svn: 193382

Only use them if the subtarget has ARM mode, as these routines are implemented
as ARM code.

Added the ability to get the SDK path for a target using the platform plugins. If LLDB lives inside an Xcode.app bundle, it will select the SDK in the Xcode bundle, else it will use the currently selected Xcode.

Also added the DWARFDataExtractor classes to the Xcode project file.

llvm-svn: 193380

This renames the GOTPLTPass to RelocationPass and refactors it to better
represent the different types of relocations.

MCStreamer: Reimplement the virtual EmitRawText as a protected member, EmitRawTextImpl, to avoid string literal ambiguities

Also improve the implementation of EmitRawText(Twine) so it doesn't
bother using the SmallString buffer if the Twine is a simple StringRef
anyway.

This reverts commit r193255 and instead creates an lto_bool_t typedef
that points to bool, _Bool, or unsigned char depending on what is
available.  Only recent versions of MSVC provide a stdbool.h header.

Although we wire up a bit for v8fp for macro setting
purposes, we don't set a macro yet. Need to ask list
about that.

Adds some Cortex-A53 strings where they were missing before.
Cortex-A57 is entirely new to clang.

Doesn't touch code only used by Darwin, in consequence of which
one of the A53 lines has been removed.
