| The memory operand might use one of the extended GPRs R8 through R15 and hence require a REX prefix, but having a REX prefix makes the high-byte register AH unencodeable as the src operand. This latent bug was exposed by this branch, presumably because `select` now happens to be putting something in an extended GPR instead of a legacy GPR. In theory this could be fixed with minimal cost by introducing a way to communicate to `select` that neither the destination memory nor the other temporary can be in an extended GPR. However, I just went for the simple solution which comes at a cost of one trivial instruction: copy the remainder from AH to AL, and *then* copy AL to the destination. | |||

| 2025-09-27 | x86_64: generate better constant memcpy code | mlugg | |
| `rep movsb` isn't usually a great idea here. This commit makes the logic which tentatively existed in `genInlineMemcpy` apply in more cases, and in particular applies it to the "new" backend logic. Put simply, all copies of 128 bytes or fewer will now attempt this path first, where---provided there is an SSE register and/or a general-purpose register available---we will lower the operation using a sequence of 32, 16, 8, 4, 2, and 1 byte copy operations. The feedback I got on this diff was "Push it to master and if it miscomps I'll revert it" so don't blame me when it explodes | |||
