unknown opcodes print as decimal
memory.copy seems not to be implemented in the binary parser. however the error message is:
unknown opcode sequence: 0xFC 0x10
which should be 0xFC 0x0A. It looks like it's printed decimal in table.c (web49_bytes_to_opcode):
unknown opcode sequence: 0xFC 0x%" PRIu8
same for the other sequences.
thank you for the bug report, i was just working on implementing the rest of 0xFC....
I am doing a medium-sized refactor and this gets handled in there too. I'll close the issue when web49 can handle all 0xFC opcodes.
you still have swapped the opcodes for (memory.copy memory.fill data.drop) https://github.com/FastVM/Web49/blob/main/src/tables.c#L1456 it should be data.drop:0x09, memory.copy:0x0a, memory.fill:0x0b
