Lioncash b6e74fd17d ir: Add opcodes for performing unsigned reciprocal square root estimates 2020-04-22 20:55:05 +01:00
Lioncash af83360f89 ir: Add opcodes for unsigned reciprocal estimate 2020-04-22 20:55:05 +01:00
Lioncash fca7eddb9e A64: Add opcodes for signed saturating negations 2020-04-22 20:53:46 +01:00
Lioncash f1ebbcd7bc emit_x64_vector: Simplify "position == 0" case for EmitVectorExtract() 
In the event position is zero, we can just treat it as a NOP, given
there's no need to move the data.

Lioncash 87372917f9 emit_x64_vector: Simplify "position == 0" case for EmitVectorExtractLower() 
In the event position == 0, we can just treat it as a simple movq,
clearing the upper half of the XMM register. This also makes that case
use only one register.

Lioncash 4507627905 emit_x64_vector: Provide AVX path for EmitVectorMinU64() 2020-04-22 20:53:46 +01:00
Lioncash fd49a62b06 emit_x64_vector: Provide AVX path for EmitVectorMinS64() 2020-04-22 20:53:46 +01:00
Lioncash 770723f449 emit_x64_vector: Provide AVX path for EmitVectorMaxU64() 2020-04-22 20:53:46 +01:00
Lioncash 8fb90c0cf1 emit_x64_vector: Provide AVX path for EmitVectorMaxS64() 2020-04-22 20:53:46 +01:00
Lioncash 2cac6ad129 emit_x64_vector: Simplify EmitVectorLogicalLeftShift8() 
Similar to EmitVectorLogicalRightShift8(), we can determine a mask ahead
of time and just and the results of a halfword left shift.

Lioncash 135107279d emit_x64_vector: Simplify EmitVectorLogicalShiftRight8() 
We can generate the mask and AND it against the result of a halfword
shift instead of looping.

Lioncash 2952b46b16 emit_x64_vector: Amend value definition in SSE 4.1 path for EmitVectorSignExtend16() 
We should be defining the value after the results have been calculated
to be consistent with the rest of the code.

Lioncash fda19095ea emit_x64_vector: Remove fallback in EmitVectorSignExtend64() 
This is fairly trivial to do manually.

Lioncash 39593fcd26 emit_x64_vector: Remove fallback for EmitVectorSignExtend32() 
We can just do the extension manually, which gets rid of the need to
fall back here.

BreadFish64 2a65442933 Backend: Create "backend" folder 
similar to the "frontend" folder
