- The following information applies to the IRIX 5 and IRIX 6 ..mmddeebbuugg
- section found in o32 objects.
-
- The MIPS symbol table departs from the standard COFF symbol table.
- The symbol table consists of many tables unbundling information
- usually found in the one COFF symbol table. The symbol table should
- be viewed as a hand-crafted, network-style database designed for space
- and access efficiency.
-
- The following structures or tables appear in the MIPS symbol table:
-
- TABLE CONTENTS
-
- symbolic header sizes and locations of all other
- tables
-
- file descriptors per file locations for other tables
-
- procedure descriptors frame info and location of
- procedure info
-
- local symbols local type, local variable, and
- scoping info
-
- local strings string space for local symbols
-
- line numbers compacted by encoding, contains a
- line per instruction
-
- relative file desc. indirection for inter-file symbol
- access
-
- optimization symbols to be defined
-
- auxiliary symbols variable data type info for each
- local symbol
-
- external symbols loader symbols (global text and
- data)
-
- external strings string space for external symbols
-
- dense numbers (file, symbol) index pairs for
- compiler use
-
- External and local symbols contain the standard concept of a
- ``symbol'' as follows:
-
- struct
- {
- long iss; /* index into string space */
- long value; /* addr, size, etc., depends on sc & st */
- unsigned st: 6; /* symbol type (e.g. local, param, etc.) */
- unsigned sc: 5; /* storage class (e.g. text, bss, etc.) */
- unsigned reserved: 1;
- unsigned index: 20; /* index into symbol or auxiliary table */
- };

- In a future IRIX release, the ..mmddeebbuugg section will be replaced.
