* 6727 - bugfix in a multiply instructionKartik Agaram2020-08-221-1/+1
| | | | Also more error-detection for this case all across the toolchain.
* 6090 - new instruction: multiply by immediateKartik Agaram2020-03-061-0/+5
| | | | | | | | | | | | | | | This is a 3-operand instruction: r32 = rm32 * imm32 It looks like https://c9x.me/x86/html/file_module_x86_id_138.html has a bug, implying the same opcode supports a 2-operand version. I don't see that in the Intel manual pdf, or at alternative sites like https://www.felixcloutier.com/x86/imul Native runs seem to validate my understanding. In the process I also fixed a bug in the existing multiply instruction 0f af: the only flags it sets are OF and CF. The other existing multiply instruction f7 was doing things right.
