# runtime.golden -- full FCML disassembly of the runtime's code region. # # GENERATED by tests/check_runtime.py --bless, then READ THE DIFF and commit. # Every line is "OFFSET BYTES MNEMONIC". This file is a deliberate # tripwire: any edit to Runtime.mod invalidates it, because inserting an # instruction renumbers everything after it, so you are forced to look at the # whole new listing and confirm you meant every change. See the "Re-baselining # the golden" section of check_runtime.py. # # Region: bytes 0..codeEnd of the runtime image (see the code/data split in # EmitData). Relative targets are absolute offsets within the runtime, which # the compiler adds to the runtime's load address when it emits a CALL. 0000 8B F0 mov si,ax 0002 8B 54 04 mov dx,word ptr [si+4h] 0005
