/* This module provides three functions: mipscoff_symfile_init,
which initializes to read a symbol file; mipscoff_new_init, which
discards existing cached information when all symbols are being
discarded; and mipscoff_symfile_read, which reads a symbol table
from a file.
mipscoff_symfile_read only does the minimum work necessary for letting the
user "name" things symbolically; it does not read the entire symtab.
Instead, it reads the external and static symbols and puts them in partial
symbol tables. When more extensive information is requested of a
file, the corresponding partial symbol table is mutated into a full
fledged symbol table by going back and reading the symbols
for real. mipscoff_psymtab_to_symtab() is called indirectly through

a pointer in the psymtab to do this.
ECOFF symbol tables are mostly written in the byte order of the
target machine. However, one section of the table (the auxiliary
symbol information) is written in the host byte order. There is a
bit in the other symbol info which describes which host byte order
was used. ECOFF thereby takes the trophy from Intel `b.out' for
the most brain-dead adaptation of a file format to byte order.
This module can read all four of the known byte-order combinations,
on any type of host. However, it does make (and check) the assumption
that the external form of a symbol table structure (on disk)
occupies the same number of bytes as the internal form (in a struct).
Fixing this is possible but requires larger structural changes. */

/* There is no guaranteed way to distinguish struct,
unions, and enums at this point. This is a bug in the
original design (that has been fixed with the
recent addition of the stStruct, stUnion, and stEnum
symbol types.) The way you can tell is if/when you
see a variable or field of that type: In that case
the variable's type (in the AUX table) says if the
type is struct, union, or enum,
and points back to the stBlock here.
So you can patch the tag kind up later - but only
if there actually is a variable or field of that type.
So until we know for sure, we will guess at this point.
The heuristic is:
If the first member has index==indexNil or a void type,
assume we have an enumeration.
* mipsread.c (parse_symbol): Avoid clobbering enum pointer when looking at its members. Improve guess between struct and union, only assuming union if multiple members have offsets of zero.

1992-01-28 02:57:37 +00:00
Otherwise, assume we have a struct.
The heuristic could guess wrong in the case of
of an enumeration with no members or a union
with one (or zero) members, or when all except the
last field of a struct have width zero.
These are uncommon and/or illegal situations, and
in any case guessing wrong probably doesn't matter much.
But if we later do find out we were wrong,
we fixup the tag kind. Members of an enumeration
must be handled differently from struct/union fields,
and that is harder to patch up, but luckily we
shouldn't need to. (If there are any enumeration
members, we can tell for sure it's an enum here.) */
