Alp Toker 86f6934e27 Change the diagnostic group for unsupported gcc optimizations added r212805
Use -Winvalid-command-line-argument here to align with existing gcc opt
diagnostics. Meanwhile -Wunused-command-line-argument is for flags that we
support but were, say, fed into the wrong invocation.

Also tweak wording to make sense with -Werror.

Saleem Abdulrasool b51d464f1e X86: correct 64-bit atomics on 32-bit
We would emit a libcall for a 64-bit atomic on x86 after SVN r212119.  This was
due to the misuse of hasCmpxchg16 to indicate if cmpxchg8b was supported on a
32-bit target.  They were added at different times and would result in the
border condition being mishandled.

This fixes the border case to emit the cmpxchg8b instruction for 64-bit atomic
operations on x86 at the cost of restoring a long-standing bug in the codegen.
We emit a cmpxchg8b on all x86 targets even where the CPU does not support this
instruction (pre-Pentium CPUs).  Although this bug should be fixed, this was
present prior to SVN r212119 and this change, so this is not really introducing
a regression.

Tim Northover 6c647eae8b X86: remove temporary atomicrmw used during lowering.
We construct a temporary "atomicrmw xchg" instruction when lowering atomic
stores for widths that aren't supported natively. This isn't on the top-level
worklist though, so it won't be removed automatically and we have to do it
ourselves once that itself has been lowered.

Daniel Sanders 8e254166e1 [mips] Correct section alignments and EntrySizes for .bss, .text, .data, .reginfo, .MIPS.options, and .MIPS.abiflags
Summary:
.bss, .text, and .data are at least 16-byte aligned.
.reginfo is 4-byte aligned and has a 24-byte EntrySize.
.MIPS.abiflags has an 24-byte EntrySize.
.MIPS.options is 8-byte aligned and has 1-byte EntrySize.

Using a 1-byte EntrySize for .MIPS.options seems strange because the
records are neither 1-byte long nor fixed-length but this matches the value
that GAS emits.

Daniel Sanders 7ddb0ab85f [mips] For the FP64A ABI, odd-numbered double-precision moves must not use mtc1/mfc1.
Summary:
This is because the FP64A the hardware will redirect 32-bit reads/writes
from/to odd-numbered registers to the upper 32-bits of the corresponding
even register. In effect, simulating FR=0 mode when FR=0 mode is not
available.

Unfortunately, we have to make the decision to avoid mfc1/mtc1 before
register allocation so we currently do this for even registers too.

FPXX has a similar requirement on 32-bit architectures that lack
mfhc1/mthc1 so this patch also handles the affected moves from the FPU for
FPXX too. Moves to the FPU were supported by an earlier commit.

NAKAMURA Takumi 6a931f507a [CMake][Win32.DLL] Let llvm_add_library(SHARED) link dependent libraries as PRIVATE.
For example, c-index-test.exe requires just libclang.dll (its import library).
When libraries in libclang were not PRIVATE but PUBLIC, c-index-test required libraries transitive by libclang.

Note, on mingw with BUILD_SHARED_LIBS, library dependencies would become more strict.
In principle, required libraries should be "required in its source file".

This will help to detect missing dependencies.

Sasa Stankovic b976fee83c [mips] Expand BuildPairF64 to a spill and reload when the O32 FPXX ABI is
enabled and mthc1 and dmtc1 are not available (e.g. on MIPS32r1)

This prevents the upper 32-bits of a double precision value from being moved to
the FPU with mtc1 to an odd-numbered FPU register. This is necessary to ensure
that the code generated executes correctly regardless of the current FPU mode.

MIPS32r2 and above continues to use mtc1/mthc1, while MIPS-IV and above continue
to use dmtc1.

Tobias Grosser c2920ff747 DeadCodeElimination: Fix liveout computation
We move back to a simple approach where the liveout is the last must-write
statement for a data-location plus all may-write statements. The previous
approach did not work out. We would have to consider per-data-access
dependences, instead of per-statement dependences to correct it. As this adds
complexity and it seems we would not gain anything over the simpler approach
that we implement in this commit, I moved us back to the old approach of
computing the liveout, but enhanced it to also add may-write accesses.

We also fix the test case and explain why we can not perform dead code
elimination in this case.

Todd Fiala 24189d4c86 Modified gdb-remote tests to run with automatically-chosen ports.
Now that llgs supports communicating the 0-port choose-a-port
mechanism and can communicate that back to a caller via the
--named-pipe option (at parity with debugserver), we use this
mechanism to always start llgs and debugserver gdb-remote
protocol tests without needing to use some port arbitration
mechanism.  This eliminates some potential intermittent failures vs. the
previous random port and collision-avoidance strategy used.

Bill Wendling 151b44d653 Support lowering of empty aggregates.
This crash was pretty common while compiling Rust for iOS (armv7). Reason -
SjLj preparation step was lowering aggregate arguments as ExtractValue +
InsertValue. ExtractValue has assertion which checks that there is some data in
value, which is not true in case of empty (no fields) structures. Rust uses
them quite extensively so this patch uses a 'select true, %val, undef'
instruction to lower the argument.

Richard Smith 19172c4f70 Superficial fix for PR20218: binding a function lvalue to a const reference to
a function pointer is neither better nor worse than binding a function lvalue
to a function rvalue reference. Don't get confused and think that both bindings
are binding to a function lvalue (which would make the lvalue form win); the
const reference is binding to an rvalue.

The "real" bug in PR20218 is still present: we're getting the wrong answer from
template argument deduction, and that's what leads us to this weird overload

Andrea Di Biagio 67d8b2e2b0 [DAGCombiner] Fix a crash caused by a missing check for legal type when trying to fold shuffles.
Verify that DAGCombiner does not crash when trying to fold a pair of shuffles
according to rule (added at r212539):
  (shuffle (shuffle A, Undef, M0), Undef, M1) -> (shuffle A, Undef, M2)

The DAGCombiner avoids folding shuffles if the resulting shuffle dag node
is not legal for the target. That means, the resulting shuffle must have
legal type and legal mask.

Before, the DAGCombiner only called method
'TargetLowering::isShuffleMaskLegal' to check if it was "safe" to fold according
to the above-mentioned rule. However, this caused a crash in the x86 backend
since method 'isShuffleMaskLegal' always expects to be called on a
legal vector type.
