* avutil/x86inc: fix warnings when assembling with Nasm 2.15Henrik Gramner2020-07-12
| | | | | | | | | Some new warnings regarding use of empty macro parameters has been added, so adjust some x86inc code to silence those. Fixes part of ticket #8771 Signed-off-by: James Almer <jamrial@gmail.com>
* libavutil: x86: Include stdlib.h before using _byteswap_ulongMartin Storsjö2020-01-23
| | | | | | | When clang works in MSVC mode, it does have the _byteswap_ulong builtin, but one has to include stdlib.h before using it. Signed-off-by: Martin Storsjö <martin@martin.st>

* | x86inc: Use .rdata instead of .rodata on WindowsHenrik Gramner2018-01-20
| | | | | | | | | | The standard section for read-only data on Windows is .rdata. Nasm will flag non-standard sections as executable by default which isn't ideal.
* | x86inc: Enable AVX emulation for floating-point pseudo-instructionsHenrik Gramner2018-01-20
| | | | | | | | | | | | | | There are 32 pseudo-instructions for each floating-point comparison instruction, but only 8 of them are actually valid in legacy-encoded mode. The remaining 24 requires the use of VEX-encoded (v-prefixed) instructions and can therefore be disregarded for this purpose.

* | x86inc: AVX-512 supportHenrik Gramner2017-12-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | AVX-512 consists of a plethora of different extensions, but in order to keep things a bit more manageable we group together the following extensions under a single baseline cpu flag which should cover SKL-X and future CPUs: * AVX-512 Foundation (F) * AVX-512 Conflict Detection Instructions (CD) * AVX-512 Byte and Word Instructions (BW) * AVX-512 Doubleword and Quadword Instructions (DQ) * AVX-512 Vector Length Extensions (VL) On x86-64 AVX-512 provides 16 additional vector registers, prefer using those over existing ones since it allows us to avoid using `vzeroupper` unless more than 16 vector registers are required. They also happen to be volatile on Windows which means that we don't need to save and restore existing xmm register contents unless more than 22 vector registers are required. Big thanks to Intel for their support.

* | Don't use _tzcnt instrinics with clang for windows w/o BMI.Dale Curtis2017-10-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Technically _tzcnt* intrinsics are only available when the BMI instruction set is present. However the instruction encoding degrades to "rep bsf" on older processors. Clang for Windows debatably restricts the _tzcnt* instrinics behind the __BMI__ architecture define, so check for its presence or exclude the usage of these intrinics when clang is present.

| * x86inc: Avoid using eax/rax for storing the stack pointerHenrik Gramner2017-01-09
| | | | | | | | | | | | | | | | | | | | | | When allocating stack space with an alignment requirement that is larger than the current stack alignment we need to store a copy of the original stack pointer in order to be able to restore it later. If we chose to use another register for this purpose we should not pick eax/rax since it can be overwritten as a return value. Signed-off-by: Anton Khirnov <anton@khirnov.net>

* | x86inc: Remove argument from WIN64_RESTORE_XMMAnton Mitrofanov2017-06-09
| | | | | | | | | | The use of rsp was pretty much hardcoded there and probably didn't work otherwise with stack_size > 0.
* | x86inc: Prefer r14/r15 over r12/r13 on x86-64Henrik Gramner2017-06-09
| | | | | | | | | | | | | | Due to a peculiarity in the ModR/M addressing encoding, the r12 and r13 registers sometimes requires an additional byte when used as a base register. r14 and r15 doesn't have that issue, so prefer using them.

| | | | | | | | | | | | We overload the `call` instruction with a macro, but it would misbehave when the macro argument wasn't a valid identifier. Fix it by explicitly checking if the argument is an identifier.
