us up to version 2.17.50.20070703, at the last GPLv2 commit. Amongst others, this added upstream support for some FreeBSD-specific things that we previously had to manually hack in, such as the OSABI label support, and so on. There are also quite a number of new files, some for cpu's (e.g. SPU) that we may or may not be interested in, but those can be cleaned up later on, if needed.

/*
|
|
* No matter what the operating system, this module must provide the
|
|
* following services to its callers.
|
|
*
|
|
* input_file_begin() Call once before anything else.
|
|
*
|
|
* input_file_end() Call once after everything else.
|
|
*
|
|
* input_file_buffer_size() Call anytime. Returns largest possible
|
|
* delivery from
|
|
* input_file_give_next_buffer().
|
|
*
|
|
* input_file_open(name) Call once for each input file.
|
|
*
|
|
* input_file_give_next_buffer(where) Call once to get each new buffer.
|
|
* Return 0: no more chars left in file,
|
|
* the file has already been closed.
|
|
* Otherwise: return a pointer to just
|
|
* after the last character we read
|
|
* into the buffer.
|
|
* If we can only read 0 characters, then
|
|
* end-of-file is faked.
|
|
*
|
|
* input_file_push() Push state, which can be restored
|
|
* later. Does implicit input_file_begin.
|
|
* Returns char * to saved state.
|
|
*
|
|
* input_file_pop (arg) Pops previously saved state.
|
|
*
|
|
* input_file_close () Closes opened file.
|
|
*
|
|
* All errors are reported so caller doesn't have to think
|
|
* about I/O errors.
