Justin Lebar 648f4cad52 [CUDA] Mark CUDA as a no-errno platform.
Summary:
CUDA doesn't support errno at all, so this is the right thing -- or at
least, in the right direction.

But also, this unbreaks the CUDA test-suite math tests [0] after D39481.
__cuda_cmath.h forwards nexttoward() to __builtin_nexttoward, which,
after that patch, was lowering to a libcall that doesn't exist in NVPTX.

Quentin Colombet b6afac1f9a [AArch64][RegisterBankInfo] Add mapping for G_FPEXT.
This fixes http://llvm.org/PR32560. We were missing a description for
half floating point type and as a result were using the FPR 32 mapping.
Because of the size mismatch the generic code was complaining that the
default mapping is not appropriate. Fix the mapping description so that
the default mapping can be properly applied.

Jake Ehrlich 13153eef56 [llvm-objcopy] Fix bug in how segment alignment was being handled
Just aligning segment offsets to segment alignment is incorrect and also
wastes more space than is needed. The requirement is that p_offset ==
p_addr modulo p_align *not* that p_offset == 0 modulo p_align. Generally
speaking we've been using p_addr == 0 modulo p_align. In fact yaml2obj
can't even produce a valid situation which causes llvm-objcopy to
produce incorrect results because alignment and offset were both
inherited from the sections the program header covers. This change fixes
this bad behavior in llvm-objcopy.

Jake Ehrlich 6fe84be9a3 Add feature to determine if host architecture is 64-bit in llvm-lit
I have a test that I'd like to add to llvm that demands using more than
32-bits worth of address space. This test can't be run on 32-bit systems
because they don't have enough address space. The host triple should be
used to determine this instead of config.host_arch because on Debian
systems config.host_arch is not correct. This change adds the
"host-arch-is-64bit" feature to allow tests to restrict themselves to
the 64-bit case.

Hiroshi Yamauchi dce9def3dd Irreducible loop metadata for more accurate block frequency under PGO.
Summary:
Currently the block frequency analysis is an approximation for irreducible
loops.

The new irreducible loop metadata is used to annotate the irreducible loop
headers with their header weights based on the PGO profile (currently this is
approximated to be evenly weighted) and to help improve the accuracy of the
block frequency analysis for irreducible loops.

This patch is a basic support for this.

Pavel Labath 64b6e5af13 Remove getCategories mechanism of specifying test categories
Summary:
This mechanism was mostly redundant with the file-based .categories
mechanism, and it was interfering with it, as any test which implemented
a getCategories method would not inherit the filesystem categories.

This patch removes it. The existing categories are preserved either by
adding a .categories file, or using the @add_test_categories decorator.

David Blaikie 0826729793 Modular Codegen: Don't home/modularize static functions in headers
Consistent with various workarounds in the backwards compatible modules
that allow static functions in headers to exist, be deduplicated to some
degree, and not generally fail right out of the gate... do the same with
modular codegen as there are enough cases (including in libstdc++ and in
LLVM itself - though I cleaned up the easy ones) that it's worth
supporting as a migration/backcompat step.

Simply create a separate, internal linkage function in each object that
needs it. If an available_externally/modularized function references a
static function, but the modularized function is eventually dropped and
not inlined, the static function will be dropped as unreferenced.

Anna Thomas 1d02b13eb7 [LoopPredication] Enable predication when latchCheckIV is wider than rangeCheck
Summary:
This patch allows us to predicate range checks that have a type narrower than
the latch check type. We leverage SCEV analysis to identify a truncate for the
latchLimit and latchStart.
There is also safety checks in place which requires the start and limit to be
known at compile time. We require this to make sure that the SCEV truncate expr
for the IV corresponding to the latch does not cause us to lose information
about the IV range.
Added tests show the loop predication over range checks that are of various
types and are narrower than the latch type.
This enhancement has been in our downstream tree for a while.

Sanjay Patel c5c8207eae [CodeGen] fix const-ness of builtin equivalents of <math.h> and <complex.h> functions that might set errno
This just makes const-ness of the builtins match const-ness of their lib function siblings. 
We're deferring fixing some of these that are obviously wrong to follow-up patches. 
Hopefully, the bugs are visible in the new test file (added at rL317220).

As the description in Builtins.def says: "e = const, but only when -fmath-errno=0".

This is step 2 of N to fix builtins and math calls as discussed in D39204.

Shoaib Meenai c542c3e0ec [cmake] Remove policy conditionals
LLVM now requires a minimum of cmake 3.4.3, and all the policies
currently being set are present in that cmake version, so the
conditionals will always be true and are therefore unnecessary. The
movation is that the conditionals can give the false impression that the
policy settings are optional, whereas for example it's necessary to set
CMP0056 in order for `check_linker_flags` to operate correctly after
r316972. Inline the project version and language setting in the process.
