DESCRIPTION
Auxiliary entries are unions with a fixed length of four bytes per entry. Much information is packed within the auxiliaries. Rather than
have the compiler front-ends handle each type of auxiliary entry directly, the following set of routines provide a high-level scalar inter-
face to the auxiliaries: Adds a type information record (TIR) to the auxiliaries. It sets the basic type (bt) to the argument and all
other fields to zero. The index to this auxiliary entry is returned. Sets the bit in the TIR, pointed to by the iaux argument. This argu-
ment says the basic type is a bit field and adds an auxiliary with its width in bits. Adds an index into the symbol table (or any other
scalar) to the auxiliaries. It sets the value to the argument that will occupy all four bytes. The index to this auxiliary entry is
returned. Adds a relative index, RNDXR, to the auxiliaries. It sets the rfd and index to their respective arguments. The index to this
auxiliary entry is returned. Works the same as st_auxrndxadd except that RNDXR is referenced by an index into the dense number table.
Copies the type from the specified file (ifd) for the specified symbol into the auxiliary table for the current file. It returns the index
to the new aux. Shifts in the specified type qualifier, tq, into the auxiliary entry TIR, which is specified by the `iaux' index into the
current file. The current type qualifiers shift up one tq so that the first tq (tq0) is free for the new entry. Adds a type qualifier in
the highest or most significant non-tqNil type qualifier. Returns the most significant type qualifier given an index into the files aux
table. Changes the iauxth aux in the current file's auxiliary table to aux. Converts the relative index (RNDXR) auxiliary, which is spec-
ified by iaux, to the specified arguments.
RESTRICTIONS
The interface will added to incrementally, as needed.
