Daniel Sanders 683ed961e1 [mips] Work around inconsistency in llvm-mc's placement of fixup markers
Summary:
Add a second fixup table to MipsAsmBackend::getFixupKindInfo() to correctly
position llvm-mc's fixup placeholders for big-endian.

See PR19836 for full details of the issue. To summarize, the fixup placeholders
do not account for endianness properly and the implementations of
getFixupKindInfo() for each target are measuring MCFixupKindInfo.TargetOffset
from different ends of the instruction encoding to compensate.

Daniel Sanders ac27263512 [mips][mips64r6] [ls][dw][lr] are not available in MIPS32r6/MIPS64r6
Summary:
Instead the system is required to provide some means of handling unaligned
load/store without special instructions. Options include full hardware
support, full trap-and-emulate, and hybrids such as hardware support within
a cache line and trap-and-emulate for multi-line accesses.

MipsSETargetLowering::allowsUnalignedMemoryAccesses() has been configured to
assume that unaligned accesses are 'fast' on the basis that I expect few
hardware implementations will opt for pure-software handling of unaligned
accesses. The ones that do handle it purely in software can override this.

mips64-load-store-left-right.ll has been merged into load-store-left-right.ll

The stricter testing revealed a Bits!=Bytes bug in passByValArg(). This has
been fixed and the variables renamed to clarify the units they hold.

Dario Domizioli 13a0a38fe0 Implemented support for "pragma clang optimize on/off", based on attribute 'optnone'.
This patch implements support for selectively disabling optimizations on a
range of function definitions through a pragma. The implementation is that
all function definitions in the range are decorated with attribute
'optnone'.

    #pragma clang optimize off
    // All function definitions in here are decorated with 'optnone'.
    #pragma clang optimize on
    // Compilation resumes as normal.

Simon Atanasyan 84242dc774 [YAML] Add an optional argument `EnumMask` to the `yaml::IO::bitSetCase()`.
Some bit-set fields used in ELF file headers in fact contain two parts.
The first one is a regular bit-field. The second one is an enumeraion.
For example ELF header `e_flags` for MIPS target might contain the
following values:

Bit-set values:

  EF_MIPS_NOREORDER = 0x00000001
  EF_MIPS_PIC       = 0x00000002
  EF_MIPS_CPIC      = 0x00000004
  EF_MIPS_ABI2      = 0x00000020

Enumeration:

  EF_MIPS_ARCH_32   = 0x50000000
  EF_MIPS_ARCH_64   = 0x60000000
  EF_MIPS_ARCH_32R2 = 0x70000000
  EF_MIPS_ARCH_64R2 = 0x80000000

For printing bit-sets we use the `yaml::IO::bitSetCase()`. It does not
support bit-set/enumeration combinations and prints too many flags from
an enumeration part. This patch fixes this problem. New method
`yaml::IO::maskedBitSetCase()` handle "enumeration" part of bitset
defined by provided mask.

Patch reviewed by Nick Kledzik and Sean Silva.

Jason Molenda ab35aa92da Instead of having an UnwindTable own a single assembly profiler,
and sharing it with all of its FuncUnwinders, have each FuncUnwinder
create an AssemblyProfiler on demand as needed.  I was worried that
the cost of creating the llvm disassemblers would be high for this
approach but it's not supposed to be an expensive operation, and it
means we don't need to add locks around this section of code.

Jason Molenda f5e8a14bd6 The UnwindTable (one per module) used to hand out shared pointers
to its unwind assembly profiler to all of the FuncUnwinders (one
per symbol) under it.  If lldb is running multiple targets, you
could get two different FuncUnwinders in the same Module trying
to use the same llvm disassembler simultaneously and that may be
a re-entrancy problem.  

Instead, the UnwindTable has the unwind assembly profiler and when
the FuncUnwinders want to use it, they get exclusive access to
the assembly profiler until they're done using it.

Rui Ueyama f713cced0e [PECOFF] Make a separate pass for /alternatename symbols.
/alternatename is a command line option to define a weak alias. You
can use it as /alternatename:foo=bar to define "foo" as a weak alias
for "bar".

Because it's a command line option, the weak alias mapping is in the
LinkingContext object, and not in a object file being read.

Previously, we looked up the mapping each time we read a new symbol
from a file, to check if there is a weak alias defined for the symbol.
That's not wrong, but had made function signature's a bit complicated --
we had to pass the mapping object to many functions. Now their
parameter lists are much cleaner.

This also has another (unrealized) benefit. parseFile() now read a
file and then add alias symbols to the file. In the first pass a
LinkingContext object is not used at all. That should make it easy
to read files from archive files speculatively, as the first pass
is free from side effect.

Rafael Espindola b73c973d3b Don't set unnamed_addr in CreateRuntimeVariable.
This was fairly broken. For example,

@__dso_handle would or would not get an unnamed_addr depending on how many
global destructors were used in a translation unit.

The consensus was that not every runtime variable is unnamed_addr and that
__dso_handle handle should not be, so just don't add unnamed_addr in
CreateRuntimeVariable.

limit graph names to the arbitrary length of 140. Random characters are still

Lang Hames 7f9fc2b339 [RuntimeDyld] Teach RuntimeDyldMachO how to handle scattered VANILLA relocs on
i386.

This fixes two more MCJIT regression tests on i386:

  ExecutionEngine/MCJIT/2003-05-06-LivenessClobber.ll
  ExecutionEngine/MCJIT/2013-04-04-RelocAddend.ll

The implementation of processScatteredVANILLA is tasteless (*ba-dum-ching*),
but I'm working on a substantial tidy-up of RuntimeDyldMachO that should
improve things.

This patch also fixes a type-o in RuntimeDyldMachO::processSECTDIFFRelocation,
and teaches that method to skip over the PAIR reloc following the SECTDIFF.
