NAME

src/byteorder.c - Byteordering functions

DESCRIPTION

These are assigned to a vtable when the PBC file is loaded.

If the vtable method for conversion from the native byteorder is called, it is a no op and will work, but the caller should know if the byteorder in the PBC file is native and skip the conversion and just map it in.

Byte order handlers

Configure will have checked for supported word sizes.

fetch_iv_le

This function converts a 4 or 8 byte INTVAL into little endian format. If the native format is already little endian, then no conversion is done.

fetch_iv_be

This function converts a 4 or 8 byte INTVAL into big endian format. If the native format is already big endian, then no conversion is done.

fetch_op_be

Same as fetch_iv_be for opcode_t

fetch_op_le

Same as fetch_iv_le for opcode_t

Unrolled routines for swapping various sizes from 32-128 bits. These should only be used if alignment is unknown or we are pulling something out of a padded buffer.
