* Create the ability to disable the specialized gemm_pack_rhs in Eigen (only ↵Gravatar Chip Kerchner2021-06-30

* Small cleanup: Get rid of the macros EIGEN_HAS_SINGLE_INSTRUCTION_CJMADD and ↵Gravatar Rasmus Munk Larsen2021-06-24
| | | | CJMADD, which were effectively unused, apart from on x86, where the change results in identically performing code.
* Get rid of code duplication for conj_helper. For packets where ↵Gravatar Rasmus Munk Larsen2021-06-24
| | | | LhsType=RhsType a single generic implementation suffices. For scalars, the generic implementation of pconj automatically forwards to numext::conj, so much of the existing specialization can be avoided. For mixed types we still need specializations.
* EIGEN_STRONG_INLINE was NOT inlining in some critical needed areas (6.6X ↵Gravatar Chip-Kerchner2021-06-16

* Fix address of temporary object errors in clang11.Gravatar Chip Kerchner2021-04-02
| | | | This fixes the problem with taking the address of temporary objects which clang11 treats as errors.

* Make half/bfloat16 constructor take inputs by value, fix powerpc test.Gravatar Antonio Sanchez2021-02-27
| | | | | | | | | | | | Since `numeric_limits<half>::max_exponent` is a static inline constant, it cannot be directly passed by reference. This triggers a linker error in recent versions of `g++-powerpc64le`. Changing `half` to take inputs by value fixes this. Wrapping `max_exponent` with `int(...)` to make an addressable integer also fixes this and may help with other custom `Scalar` types down-the-road. Also eliminated some compile warnings for powerpc.
* Fix clang compile when no MMA flags are set. Simplify MMA compiler detection.Gravatar Chip-Kerchner2021-02-24

* Having forward template function declarations in a P10 file causes bad code ↵Gravatar Chip-Kerchner2021-02-24

* Fixes to support old and new versions of the compilers for built-ins. Cast ↵Gravatar Chip-Kerchner2021-02-24

* Updated pfrexp implementation.Gravatar Antonio Sanchez2021-02-17
| | | | | | The original implementation fails for 0, denormals, inf, and NaN. See #2150
* Fix ldexp implementations.Gravatar Antonio Sanchez2021-02-10
| | | | | | | | | | | | | | | | | The previous implementations produced garbage values if the exponent did not fit within the exponent bits. See #2131 for a complete discussion, and !375 for other possible implementations. Here we implement the 4-factor version. See `pldexp_impl` in `GenericPacketMathFunctions.h` for a full description. The SSE `pcmp*` methods were moved down since `pcmp_le<Packet4i>` requires `por`. Left as a "TODO" is to delegate to a faster version if we know the exponent does fit within the exponent bits. Fixes #2131.
* Eliminate implicit conversions from float to double.Gravatar Antonio Sanchez2021-02-01

* Fix altivec packetmath.Gravatar Antonio Sanchez2021-01-28
| | | | | | | | | | | | | | | Allows the altivec packetmath tests to pass. There were a few issues: - `pstoreu` was missing MSQ on `_BIG_ENDIAN` systems - `cmp_*` didn't properly handle conversion of bool flags (0x7FC instead of 0xFFFF) - `pfrexp` needed to set the `exponent` argument. Related to !370, #2128 cc: @ChipKerchner @pdrocaldeira Tested on `_BIG_ENDIAN` running on QEMU with VSX. Couldn't figure out build flags to get it to work for little endian.

* Fix compilation without vector engine available (e.g., x86 with SSE disabled):Gravatar Gael Guennebaud2019-09-05

|
* Add missing pcmp_XX methods for double/Packet2dGravatar João P. L. de Carvalho2019-08-14
| | | | This actually fixes an issue in unit-test packetmath_2 with pcmp_eq when it is compiled with clang. When pcmp_eq(Packet4f,Packet4f) is used instead of pcmp_eq(Packet2d,Packet2d), the unit-test does not pass due to NaN on ref vector.
* Fix packed load/store for PowerPC's VSXGravatar João P. L. de Carvalho2019-08-09
| | | | | | | | The vec_vsx_ld/vec_vsx_st builtins were wrongly used for aligned load/store. In fact, they perform unaligned memory access and, even when the address is 16-byte aligned, they are much slower (at least 2x) than their aligned counterparts. For double/Packet2d vec_xl/vec_xst should be prefered over vec_ld/vec_st, although the latter works when casted to float/Packet4f. Silencing some weird warning with throw but some GCC versions. Such warning are not thrown by Clang.
* Fix offset argument of ploadu/pstoreu for AltivecGravatar João P. L. de Carvalho2019-08-09
| | | | | | | | | | If no offset is given, them it should be zero. Also passes full address to vec_vsx_ld/st builtins. Removes userless _EIGEN_ALIGNED_PTR & _EIGEN_MASK_ALIGNMENT. Removes unnecessary casts.
* bug #1718: Add cast to successfully compile with clang on PowerPCGravatar João P. L. de Carvalho2019-08-09
| | | | Ignoring -Wc11-extensions warnings thrown by clang at Altivec/PacketMath.h
