Justin Bogner 38e5217b1e X86: Wrap a helper for an assert in #ifndef NDEBUG
This function is used in exactly one place, and only in asserts
builds. Move it a few lines up before the use and only define it when
asserts are enabled. Fixes the release build under -Werror.

Also remove the forward declaration and commentary that was basically
identical to the code itself.

James Y Knight 29b5f086ca Default vaarg lowering should support indirect struct types.
Fixes PR11517 for SPARC.

On most targets, clang lowers va_arg itself, eschewing the use of the
llvm vaarg instruction. This is necessary (at least for now) as the type
argument to the vaarg instruction cannot represent all the ABI
information that is needed to support complex calling conventions.

However, on targets with a simpler varrags ABIs, the LLVM instruction
can work just fine, and clang can simply lower to it. Unfortunately,
even on such targets, vaarg with a struct argument would fail, because
the default lowering to vaarg was naive: it didn't take into account the
ABI attribute computed by classifyArgumentType. In particular, for the
DefaultABIInfo, structs are supposed to be passed indirectly and so
llvm's vaarg instruction should be emitted with a pointer argument.

Now, vaarg instruction emission is able to use computed ABIArgInfo for
the provided argument type, which allows the default ABI support to work
for structs too.

I haven't touched the EmitVAArg implementation for PPC32_SVR4 or XCore,
although I believe both are now redundant, and could be switched over to
use the default implementation as well.

Sanjay Patel 75b4ae25cb [InstCombine] refactor visitOr() to use foldCastedBitwiseLogic()
Note: The 'and' case in foldCastedBitwiseLogic() is inheriting one extra
check from the nearly identical 'or' case:
  if ((!isa<ICmpInst>(Cast0Src) || !isa<ICmpInst>(Cast1Src))

But I'm not sure how to expose that difference in a regression test. 
Without that check, the 'or' path will infinite loop on:
test/Transforms/InstCombine/zext-or-icmp.ll
because the zext-or-icmp fold is attempting a reverse transform.

The refactoring should extend to the 'xor' case next to solve part of
PR26702.

Sean Callanan fed0e758cb When looking for symbols, find load addresses in a more robust way.
IRExecutionUnit previously replicated a bunch of logic that already
existed elsewhere for the purpose of getting a load address for a
symbol.  This approach failed to resolve certain types of symbols.
Instead, we now use functions on SymbolContext to do the address
resolution.

This is a cleanup of IRExecutionUnit::FindInSymbols, and also fixes a
latent bug where we looked at the wrong SymbolContext to determine
whether or not it is external.

Vedant Kumar 120f6301ed [profile] Fix iteration over profile data entries
Fix a crash when gathering value profile data on i386 Darwin.

The Darwin linker shrinks sections containing aligned structures when
padding is not explicitly added to the end of the structure. When
iterating over these structures, be sure to not walk past the end of the
section.

No tests added, since running `ninja check-profile` on i386 Darwin is
enough to reproduce the original crash.

Chris Bieneman c90e12fe9f [CMake] Create an install-distribution target driven by LLVM_DISTRIBUTION_COMPONENTS
The idea here is to provide a customizable install target that only depends on building the things you actually want to install. It relies on each component being installed having an auto-generated install-${component}, which in turn depends only on the target being installed.

This is fundamentally a workaround for the fact that CMake generates build files which have their "install" target depend on the "all" target. This results in "ninja install" building a bunch of unneeded things.

Rafael Espindola 435c00f39c Fix the aarch64 logic for dynamic relocations.
There is nothing aarch64 specific in here. If a symbol can be preempted,
we need to copy the full relocation to the dynamic linker.

If a symbol cannot be preempted, we can make the dynamic linker life
easier and produce a relative relocation.

This is directly equivalent to R_X86_64_64 to R_x86_64_RELATIVE
conversion.

Adrian Prantl 4594606c00 Reapply r261657.
Remove an unnecessary workaround introduced in r259975. (NFC)

Now that LLVM r259973 allows replacing a temporary type with another
temporary we can rely on the original implementation.

It is possible for enums to be created as part of
their own declcontext. In this case a FwdDecl will be created
twice. This doesn't cause a problem because both FwdDecls are
entered into the ReplaceMap: finalize() will replace the first
FwdDecl with the second and then replace the second with
complete type.

Thanks to echristo for pointing this out.
