Imdeed, the files contain bytecode. Here is a sample input:
=============
ACPI_EXTRACT_ALL_CODE ssdp_susp_aml
DefinitionBlock ("ssdt-susp.aml", "SSDT", 0x01, "BXPC", "BXSSDTSUSP", 0x1)
{
Scope(\) {
ACPI_EXTRACT_NAME_STRING acpi_s3_name
Name (_S3, Package (0x04)
{
One, /* PM1a_CNT.SLP_TYP */
One, /* PM1b_CNT.SLP_TYP */
Zero, /* reserved */
Zero /* reserved */
})
ACPI_EXTRACT_NAME_STRING acpi_s4_name
ACPI_EXTRACT_PKG_START acpi_s4_pkg
Name (_S4, Package (0x04)
{
0x2, /* PM1a_CNT.SLP_TYP */
0x2, /* PM1b_CNT.SLP_TYP */
Zero, /* reserved */
Zero /* reserved */
})
Name (_S5, Package (0x04)
{
Zero, /* PM1a_CNT.SLP_TYP */
Zero, /* PM1b_CNT.SLP_TYP */
Zero, /* reserved */
Zero /* reserved */
})
}
}
=============
and the distributed file could be (depending on the details of the
build process) either something like this:
=============
static unsigned char ssdp_susp_aml[] = { 0x53,
0x53, 0x44, 0x54, 0x4e, 0x0, 0x0, 0x0, 0x1, 0x45, 0x42, 0x58, 0x50, 0x43,
0x0, 0x0, 0x42, 0x58, 0x53, 0x53, 0x44, 0x54, 0x53, 0x55, 0x1, 0x0, 0x0,
0x0, 0x49, 0x4e, 0x54, 0x4c, 0x28, 0x5, 0x10, 0x20, 0x10, 0x29, 0x5c,
0x0, 0x8, 0x5f, 0x53, 0x33, 0x5f, 0x12, 0x6, 0x4, 0x1, 0x1, 0x0, 0x0,
0x8, 0x5f, 0x53, 0x34, 0x5f, 0x12, 0x8, 0x4, 0xa, 0x2, 0xa, 0x2, 0x0,
0x0, 0x8, 0x5f, 0x53, 0x35, 0x5f, 0x12, 0x6, 0x4, 0x0, 0x0, 0x0, 0x0 };

or something like this:
