This backs out changes in commit r198605 and part of r198604, replacing the
original tok::kw_template with a slightly more obvious placeholder
tok::unknown.

Move the unwinding context for the ARM IAS into a helper class. This is purely
a structural refactoring. A follow up change allows for recording additional
depth to improve diagnostics.
llvm-svn: 198664
Parse tag names as well as expressions. The former is part of the
specification, the latter is for improved compatibility with the GNU assembler.
Fix attribute value handling to be comformant to the specification.
llvm-svn: 198662
Introduce a new virtual method Note into the AsmParser. This completements the
existing Warning and Error methods. Use the new method to clean up the output
of the unwind routines in the ARM AsmParser.

It controls everything that -flimit-debug-info used to, plus the
vtable type optimization. The old -fno-limit-debug-info option is now an
alias to -fstandalone-debug and vice versa.
Standalone is the default on Darwin until dtrace is updated to work with
non-standalone debug info (rdar://problem/15758808).
Note: I kept the LimitedDebugInfo name in CodeGenOptions::DebugInfoKind
because NoStandaloneDebugInfo sounded even more confusing.

This is a follow up of the r198338 commit that added truncates for
lcssa phi nodes. Sinking the truncates below the phis cleans up the
loop and simplifies subsequent analysis within the indvars pass.

and EmulateInstructionARM::GetFramePointerDWARFRegisterNumber to recognize
the Apple arm convention (of using r7 for the frame pointer, regardless of
thumb or arm) even if the OS does not match Darwin/MacOSX/iOS. Also
corrects the behavior for thumb code on non-Apple platforms.

This patch adds .abicalls and .set pic0 support which
affects the ELF ABI and its flags. In addition the patch uses
a common interface for both the MipsTargetSteamer and
MipsObjectStreamer that both the integrated and standalone
assemblers will use for the output for these directives.

Otherwise on (some) 64-bit systems, -Wformat will trigger a warning
because uint64_t is an 'unsigned long' not an 'unsigned long long'.
Consequently, PGOProfiling.c would fail to build if -Werror and
-Wformat are both enabled.
llvm-svn: 198644
This is fairly minimal support for instrumentation based PGO. The data
format is inefficient, and the output file name is hardcoded to
pgo-data.
llvm-svn: 198638
SymbolLookUp() call back to return a demangled C++ name to
be used as a comment.
For example darwin's otool(1) program the uses the llvm
disassembler now can produce disassembly like:
callq __ZNK4llvm6Target20createMCDisassemblerERKNS_15MCSubtargetInfoE ## llvm::Target::createMCDisassembler(llvm::MCSubtargetInfo const&) const
Also fix a bug in LLVMDisasmInstruction() that was not flushing
the raw_svector_ostream for the disassembled instruction string
before copying it to the output buffer that was causing truncation
of the output.

Now with a fix for PR18384: ValueHandleBase::ValueIsDeleted.
We need to invalidate SCEV's loop info when we delete a block, even if no values are hoisted.

Summary:
This parameter is required to build C++11 projects (like lld or lldb) on OS X as the default STL does not provide c++ classes.

llvm-svn: 198625
The ARM backend has been using most of the MachO related subtarget
checks almost interchangeably, and since the only target it's had to
run on has been IOS (which is all three of MachO, Darwin and IOS) it's
worked out OK so far.
But we'd like to support embedded targets under the "*-*-none-macho"
triple, which means everything starts falling apart and inconsistent
behaviours emerge.
This patch should pick a reasonably sensible set of behaviours for the
new triple (and any others that come along, with luck). Some choices
were debatable (notably FP == r7 or r11), but we can revisit those
later when deficiencies become apparent.

This requires a knowledge of the stack size which is not known until
the frame is complete, hence the need for the XCoreFTAOElim pass
which lowers the XCoreISD::FRAME_TO_ARGS_OFFSET instrution into its
final form.
llvm-svn: 198614
We also narrow the liveness of FP & LR during the prologue to
reflect the actual usage of the registers.
I have been unable to construct a test to prove the previous live
range was too large.
