c4b99f78c7 Fix breakage in pcast<Packet2l, Packet2d> due to _mm_cvtsi128_si64 not being available on 32 bit x86. 
If SSE 4.1 is available use the faster _mm_extract_epi64 intrinsic.

880fa43b2b Add support for CastXML on ARM aarch64 
CastXML simulates the preprocessors of other compilers, but actually
parses the translation unit with an internal Clang compiler.
Use the same `vld1q_u64` workaround that we do for Clang.

Fixes: #1979

cc0c38ace8 Remove old Clang compiler bug work-arounds. The two LLVM bugs referenced in the comments here have long been fixed. The workarounds were now detrimental because (1) they prevented using fused mul-add on Clang/ARM32 and (2) the unnecessary 'volatile' in 'asm volatile' prevented legitimate reordering by the compiler. 2020-09-15 20:54:14 -04:00

603e213d13 Fixing a CUDA / P100 regression introduced by PR 181 
PR 181 ( https://gitlab.com/libeigen/eigen/-/merge_requests/181 ) adds `__launch_bounds__(1024)` attribute to GPU kernels, that did not have that attribute explicitly specified.

That PR seems to cause regressions on the CUDA platform. This PR/commit makes the changes in PR 181, to be applicable for HIP only

c6820a6316 Replace the call to int64_t in the blasutil test by explicit types 
Some platforms define int64_t to be long long even for C++03. If this is
the case we miss the definition of internal::make_unsigned for this
type. If we just define the template we get duplicated definitions
errors for platforms defining int64_t as signed long for C++03.

We need to find a way to distinguish both cases at compile-time.

21122498ec Temporarily turn off the NEON implementation of pfloor as it does not work for large values. 
The NEON implementation mimics the SSE implementation, but didn't mention the caveat that due to the unsigned of signed integer conversions, not all values in the original floating point  represented are supported.

c1ffe452fc Fix bfloat16 casts 
If we have explicit conversion operators available (C++11) we define
explicit casts from bfloat16 to other types. If not (C++03), we don't
define conversion operators but rely on implicit conversion chains from
bfloat16 over float to other types.

0e1a33a461 Faster conversion from integer types to bfloat16 
Specialized `bfloat16_impl::float_to_bfloat16_rtne(float)` for normal floating point numbers, infinity and zero, in order to improve the performance of `bfloat16::bfloat16(const T&)` for integer argument types.

A reduction of more than 20% of the runtime duration of conversion from int to bfloat16 was observed, using Visual C++ 2019 on Windows 10.

b11f817bcf Avoid undefined behavior by union type punning in float_to_bfloat16_rtne 
Use `numext::as_uint`, instead of union based type punning, to avoid undefined behavior.
See also C++ Core Guidelines: "Don't use a union for type punning"
https://github.com/isocpp/CppCoreGuidelines/blob/v0.8/CppCoreGuidelines.md#c183-dont-use-a-union-for-type-punning

`numext::as_uint` was suggested by David Tellenbach
