The fields Creator ID and Creator Revision contain information about the tool that created an ACPI table. This may be the ASL compiler for some tables but it is not for others. Naming these fields aslc_id and aslc_revision is misleading.
It is usual to see diverse values of Creator ID. On a laptop I saw these: 'AMD ', 'INTL, 'MSFT', 'PTEC'. Obviously not all relate to the Intel ASL compiler.
