| # In the XED data, *all* floating point bitwise logic operation has their | |
| # operand type marked as uint. We are not trying to understand why Intel | |
| # decided that they want FP bit-wise logic operations, but this irregularity | |
| # has to be dealed with in separate rules with some overwrites. | |
| # For many bit-wise operations, we have the following non-orthogonal | |
| # choices: | |
| # | |
| # - Non-masked AVX operations have no element width (because it | |
| # doesn't matter), but only cover 128 and 256 bit vectors. | |
| # | |
| # - Masked AVX-512 operations have an element width (because it needs | |
| # to know how to interpret the mask), and cover 128, 256, and 512 bit | |
| # vectors. These only cover 32- and 64-bit element widths. | |
| # | |
| # - Non-masked AVX-512 operations still have an element width (because | |
| # they're just the masked operations with an implicit K0 mask) but it | |
| # doesn't matter! This is the only option for non-masked 512 bit | |
| # operations, and we can pick any of the element widths. | |
| # | |
| # We unify with ALL of these operations and the compiler generator | |
| # picks when there are multiple options. | |
| # TODO: We don't currently generate unmasked bit-wise operations on 512 bit | |
| # vectors of 8- or 16-bit elements. AVX-512 only has *masked* bit-wise | |
| # operations for 32- and 64-bit elements; while the element width doesn't matter | |
| # for unmasked operations, right now we don't realize that we can just use the | |
| # 32- or 64-bit version for the unmasked form. Maybe in the XED decoder we | |
| # should recognize bit-wise operations when generating unmasked versions and | |
| # omit the element width. | |
| # For binary operations, we constrain their two inputs and one output to the | |
| # same Go type using a variable. | |
