Summary: InstCombine needs to be performed after simplifycfg and sroa, otherwise it may make bad optimization decisions.

We would incorrectly emit the directive sections due to the missing overridden
methods. We now emit the expected "/DEFAULTLIB" rather than "-l" options for
requested linkage

Add support for /Ob1 (and equivalent -finline-hint-functions), which enable
inlining only for functions marked inline, either explicitly (via inline
keyword, for example), or implicitly (function definition in class body,
for example).
This works by enabling inlining pass, and adding noinline attribute to
every function not marked inline.
Patch by Rudy Pons <rudy.pons@ilod.org>!

It currently only takes 2048 gotos to overflow the FixupDepth bitfield,
causing silent miscompilation. Apparently some parser generators run into
this (see PR).
I don't know that that data structure is terribly size sensitive anyway,
and since there's no room to widen the bitfield, let's just use a separate
word in EHCatchScope for it.

This new test tests that functions are capable of being imported, rather than
that the import pass is run. This new test is compatible with the approach
being developed in D20268 which runs the importer on its own rather than in
a pass.

Summary:
If the RenderScript LangOpt is set, either via '-x renderscript' or the '.rs'
file extension, set the DWARF language tag to be that of RenderScript.

This is a fix for PR28112:
https://llvm.org/bugs/show_bug.cgi?id=28112
The FP comparison intrinsics that take an immediate parameter (rather than specifying
a comparison predicate in the function name) were added with AVX; these are macros in
avxintrin.h. This patch makes clang behavior match gcc (error if a program tries to use
these without -mavx) and matches the Intel documentation, eg:
VCMPPS: m128 _mm_cmp_ps(m128 a, __m128 b, const int imm)
'V' means this is intended to only work with the AVX form of the instruction.

Summary: We need to call PruneEH pass before AutoFDO pass so that some EH-related calls can get inlined in Sample Profile pass.

Given something like:
void *v = (void *)100;
We need to synthesize a ptrtoint operation from 100. During constant
emission, we choose i64 as the type for our constant because it
guaranteed not to drop any bits from our CharUnits representation of the
value. However, this is suboptimal for 32-bit targets: LLVM passes like
GlobalOpt will get confused by these sorts of casts resulting in
pessimization.
Instead, make sure the ptrtoint operand has a pointer-sized integer
type.

Reapplying patch in r272777 which was reverted
because the llvm patch which added support
for generating the mcrr/mcrr2 instructions
from the intrinsic was causing an assertion
failure. This has now been fixed in llvm.

This patch fixes a bug where we'd segfault (in some cases) if we saw a
variadic function with one or more pass_object_size arguments.

As noted in the code comment, a potential follow-on would be to remove
the builtins themselves. Other than ord/unord, this already works as
expected. Eg:
typedef float v4sf __attribute__((__vector_size__(16)));
v4sf fcmpgt(v4sf a, v4sf b) { return a > b; }

Patch adds intrinsics for mrrc/mrrc2. The
intrinsics for mrrc/mrrc2 return a single
uint64_t to represent two 32 bit values.
The mcrr/mcrr2 intrinsic was changed to
accept a single uint64_t instead of two
32 bit values as the input for consistency.

There is no need to use a target-specific intrinsic to implement
_bit_scan_forward or _bit_scan_reverse, reimplementing them using
generic intrinsics makes it more likely that the middle end will
understand what's going on.
llvm-svn: 272564
We can now use __builtin_nontemporal_store instead of target specific builtins for naturally aligned nontemporal stores which avoids the need for handling in CGBuiltin.cpp
The scalar integer nontemporal (unaligned) store builtins will have to wait as __builtin_nontemporal_store currently assumes natural alignment and doesn't accept the 'packed struct' trick that we use for normal unaligned load/stores.
The nontemporal loads require further backend support before we can safely convert them to __builtin_nontemporal_load

Summary:
Create a new Frontend LangOpt to specify the renderscript language. It
is enabled by the "-x renderscript" option from the driver.
Add a "kernel" function attribute only for RenderScript (an "ignored
attribute" warning is generated otherwise).
Make the NativeHalfType and NativeHalfArgsAndReturns LangOpts be implied
by the RenderScript LangOpt.
