29c17db650 Add support for getting the last modification time from a file_status. 
Use that in llvm-ar.cpp to replace a use of sys::PathWithStatus.

a1694e5784 [APFloat] Rename isIEEENormal => isNormal and remove old isNormal method. 
The old isNormal is already functionally replaced by the method isFiniteNonZero
in r184350 and all references to said method were replaced in LLVM/clang in
r184356/134366.

4cbbbf49b6 This reverts r155000. 
The cdp2 instruction should have the same restrictions as cdp on the
co-processor registers.

VFP instructions on v8/AArch32 share the same encoding space as cdp2.

This (hopefully) fixes build failures resulting from r184436;
the PowerPC asm parser now depends on PowerPC target expresssions.

151ad37fed [MC] Support @ variants with directional labels 
The assembler parser common code supports recognizing symbol variants
using the @ modifer.  On PowerPC, it should also be possible to use
(some of) those modifiers with directional labels, like "1f@l".

This patch adds support for accepting symbol variants on directional
labels as well.

027e94479c [PowerPC] Optimize @ha/@l constructs 
This patch adds support for having the assembler optimize fixups
to constructs like "symbol@ha" or "symbol@l" if "symbol" can be
resolved at assembler time.

This optimization is already present in the PPCMCExpr.cpp code
for handling PPC_HA16/PPC_LO16 target expressions.  However,
those target expression were used only on Darwin targets.

This patch changes target expression code so that they are
usable also with the GNU assembler (using the @ha / @l syntax
instead of the ha16() / lo16() syntax), and changes the
MCInst lowering code to generate those target expressions
where appropriate.

It also changes the asm parser to generate HA16/LO16 target
expressions when parsing assembler source that uses the
@ha / @l modifiers.  The effect is that now the above-
mentioned optimization automatically becomes available
for those situations too.

0db5379fe6 [PowerPC] Support compare mnemonics with implied CR0 
Just like for branch mnemonics (where support was recently added), the
assembler is supposed to support extended mnemonics for the compare
instructions where no condition register is specified explicitly
(and CR0 is assumed implicitly).

This patch adds support for those extended compare mnemonics.

4532c280f5 DebugInfo: don't use location lists when the location covers the whole function anyway 
Fix up three tests - one that was relying on abbreviation number,
another relying on a location list in this case (& testing raw asm,
changed that to use dwarfdump on the debug_info now that that's where
the location is), and another which was added in r184368 - exposing a
bug in that fix that is exposed when we emit the location inline rather
than through a location list. Fix that bug while I'm here.

4e91fa3834 [Support/CrashRecoveryContext] Make sure CrashRecoveryContext does not clear the thread-local "CurrentContext" 
in the "parent" thread, when we are using CrashRecoveryContext::RunSafelyOnThread.

When using CrashRecoveryContext::RunSafelyOnThread, we would set a CrashRecoveryContextImpl* to a thread-local variable
for the "child" thread, but CrashRecoveryContext would erroneously clear it in the "parent" thread.

The result was that if CrashRecoveryContext::RunSafelyOnThread was called again in the "child" thread it would mess up
crash-recovery for its parent.

A test for this will be added in the clang repository.

0159ae4295 DebugInfo: PR14763/r183329 correct the location of indirect parameters 
We had been papering over a problem with location info for non-trivial
types passed by value by emitting their type as references (this caused
the debugger to interpret the location information correctly, but broke
the type of the function). r183329 corrected the type information but
lead to the debugger interpreting the pointer parameter as the value -
the debug info describing the location needed an extra dereference.

Use a new flag in DIVariable to add the extra indirection (either by
promoting an existing DW_OP_reg (parameter passed in a register) to
DW_OP_breg + 0 or by adding DW_OP_deref to an existing DW_OP_breg + n
(parameter passed on the stack).

c971cb8281 DebugInfo: Specify that a value is stored indirectly 
This is a precursor to fix a regression caused by PR14763/r183329 where
the location of a non-trivial pass-by-value parameter ends up
incorrectly referring directly to the parameter (a pointer) rather than
the object pointed to by the pointer.

3df7d2f70b llvm-dwarfdump: Add support for dumping the .debug_loc section 
This is a basic implementation - we still don't have any support (that I
know of) for dumping DWARF expressions in a meaningful way, so the
location information itself is just printed as a sequence of bytes as we
do elsewhere.

4df4bccc71 [MC/DWARF] Generate multiple .debug_line entries for adjacent .loc directives 
The compiler occasionally generates multiple .loc directives in a row
(at the same instruction address).  These need to be transformed into
multple actual .debug_line table entries, since they are used to signal
certain information to the debugger (e.g. if the opening brace of a
function body is on the same line as the declaration).

The MCAsmStreamer version of EmitDwarfLocDirective handles this
correctly by emitting a .loc directive every time it is called.
However, the MCObjectStream version simply defaults to recording
the information and emitting only a single table entry later,
e.g. when EmitInstruction is called.

This patch introduces a MCAsmStreamer::EmitDwarfLocDirective
version that emits a line table entry for a .loc directive
that may already be pending before recording the new directive.
(This is similar to how this is handled in GNU as.)

With this patch (and the code alignment factor patch) applied,
I'm now getting identical DWARF .debug sections for all test-suite
object files on PowerPC for the internal and the external assembler.

07969dc8ae [APFloat] Converted all references to APFloat::isNormal => APFloat::isFiniteNonZero. 
Turns out all the references were in llvm and not in clang.
