Bug 248568 – [WebAssembly SIMD] Support vector comparisons on Intel

• Status: RESOLVED
• Resolution: FIXED
• Component: WebAssembly

[David Degazio]

We should add support for vector comparison instructions to the x86_64 macro assembler.

[David Degazio]

For reference, this involves adding support for the following instructions:

 - i8x16.eq, i16x8.eq, i32x4.eq, i64x2.eq, f32x4.eq, f64x2.eq
 - i8x16.ne, i16x8.ne, i32x4.ne, i64x2.ne, f32x4.ne, f64x2.ne
 - f32x4.lt, f64x2.lt
 - f32x4.le, f64x2.le
 - f32x4.gt, f64x2.gt
 - f32x4.ge, f64x2.ge
 - i8x16.lt_s, i16x8.lt_s, i32x4.lt_s, i64x2.lt_s
 - i8x16.le_s, i16x8.le_s, i32x4.le_s, i64x2.le_s
 - i8x16.gt_s, i16x8.gt_s, i32x4.gt_s, i64x2.gt_s
 - i8x16.ge_s, i16x8.ge_s, i32x4.ge_s, i64x2.ge_s
 - i8x16.lt_u, i16x8.lt_u, i32x4.lt_u
 - i8x16.le_u, i16x8.le_u, i32x4.le_u
 - i8x16.gt_u, i16x8.gt_u, i32x4.gt_u
 - i8x16.ge_u, i16x8.ge_u, i32x4.ge_u
