Saleem Abdulrasool 6e9e88b30a CodeGen: support linker options on Windows ARM
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

Chris Dewhurst 7e7ee962f6 [Sparc] Complex return value ABI compliance.
According to the Sparc V8 ABI, complex numbers should be passed and returned as pairs of registers:

https://docs.oracle.com/cd/E26502_01/html/E28387/gentextid-2734.html

This fix ensures this is the case. Without this, complex numbers are returned as a struct of two floats, which breaks the ABI rules.

Oleg Ranevskyy 7232f66051 [CodeGen] Clang does not choose aapcs-vfp calling convention for ARM bare metal target with hard float (EABIHF)
Summary:
Clang does not detect `aapcs-vfp` for the EABIHF environment. The reason is that only GNUEABIHF is considered while choosing calling convention, EABIHF is ignored.

This causes clang to use `aapcs` for EABIHF and add the `arm_aapcscc` specifier to functions in generated IR.

The modified `arm-cc.c` test checks that no calling convention specifier is added to functions for EABIHF, which means the default one is used (`CallingConv::ARM_AAPCS_VFP`).

Tim Northover 360d2b3325 AArch64: simplify illegal vector check. NFC.
Use a utility function to check whether the number of elements is a power of 2
and drop the redundant upper limit (a 128-bit vector with more than 16 elements
would have each element < 8 bits, not possible).

Reid Kleckner 0404605dda Expand aggregate arguments more often on 32-bit Windows
Before this change, we would pass all non-HFA record arguments on
Windows with byval. Byval often blocks optimizations and results in bad
code generation. Windows now uses the existing workaround that other
x86_32 platforms use.

I also expanded the workaround to handle C++ records with constructors
on Windows. On non-Windows platforms, we have to keep generating the
same LLVM IR prototypes if we want our bitcode to be ABI compatible.
Otherwise we will encounter mismatch issues like PR21573.

Essentially fixes PR27522 in Clang instead of LLVM.

Ahmed Bougacha 40a34c2e2a [CodeGen] Widen non-power-of-2 vector HFA base types.
Currently, for the ppc64--gnu and aarch64 ABIs, we recognize:
  typedef __attribute__((__ext_vector_type__(3))) float v3f32;
  typedef __attribute__((__ext_vector_type__(16))) char v16i8;
  struct HFA {
    v3f32 a;
    v16i8 b;
  };

as an HFA. Since the first type encountered is used as the base type,
we pass the HFA as:
    [2 x <3 x float>]
Which leads to incorrect IR (relying on padding values) when the
second field is used.

Instead, explicitly widen the vector (after size rounding) in
isHomogeneousAggregate.

Reid Kleckner 9305fd1f86 [CodeGen] Avoid ctor/dtor boilerplate with some C++11
Non-owning pointers that cache LLVM types and constants can use
'nullptr' default member initializers so that we don't need to mention
them in the constructor initializer list.

Owning pointers should use std::unique_ptr so that we don't need to
manually delete them in the destructor. They also don't need to be
mentioned in the constructor at that point.

Saleem Abdulrasool 10a4972a8d revert SVN r265702, r265640
Revert the two changes to thread CodeGenOptions into the TargetInfo allocation
and to fix the layering violation by moving CodeGenOptions into Basic.
Code Generation is arguably not particularly "basic".  This addresses Richard's
post-commit review comments.  This change purely does the mechanical revert and
will be followed up with an alternate approach to thread the desired information
into TargetInfo.

Summary:
r246764 handled __fp16 arguments and returns for AAPCS, but skipped this
handling for OpenCL.  Simlar to OpenCL, RenderScript also handles __fp16
type natively.

This patch adds the -fnative-half-arguments-and-returns command line
flag to allow such languages to skip this coercion of __fp16.
