/* General information:
|
|
|
|
This header file defines and describes only the data structures
|
|
necessary to read debug symbols produced by the HP C compiler,
|
|
HP ANSI C++ compiler, and HP FORTRAN 90 compiler using the
|
|
SOM object file format.
|
|
(For a full description of the debug format, ftp hpux-symtab.h from
|
|
jaguar.cs.utah.edu:/dist).
|
|
|
|
Additional notes (Rich Title)
|
|
This file is a reverse-engineered version of a file called
|
|
"symtab.h" which exists internal to HP's Computer Languages Organization
|
|
in /CLO/Components/DDE/obj/som/symtab.h. Because HP's version of
|
|
the file is copyrighted and not distributed, it is necessary for
|
|
GDB to use the reverse-engineered version that follows.
|
|
Work was done by Cygnus to reverse-engineer the C subset of symtab.h.
|
|
The WDB project has extended this to also contain the C++
|
|
symbol definitions, the F90 symbol definitions,
|
|
and the DOC (debugging-optimized-code) symbol definitions.
|
|
In some cases (the C++ symbol definitions)
|
|
I have added internal documentation here that
|
|
goes beyond what is supplied in HP's symtab.h. If we someday
|
|
unify these files again, the extra comments should be merged back
|
|
into HP's symtab.h.

-------------------------------------------------------------------
|
|
|
|
Debug symbols are contained entirely within an unloadable space called
|
|
$DEBUG$. $DEBUG$ contains several subspaces which group related
|
|
debug symbols.
|
|
|
|
$GNTT$ contains information for global variables, types and contants.
|
|
|
|
$LNTT$ contains information for procedures (including nesting), scoping
|
|
information, local variables, types, and constants.
|
|
|
|
$SLT$ contains source line information so that code addresses may be
|
|
mapped to source lines.
|
|
|
|
$VT$ contains various strings and constants for named objects (variables,
|
|
typedefs, functions, etc). Strings are stored as null-terminated character
|
|
lists. Constants always begin on word boundaries. The first byte of
|
|
the VT must be zero (a null string).
|
|
|
|
$XT$ is not currently used by GDB.
|
|
|
|
Many structures within the subspaces point to other structures within
|
|
the same subspace, or to structures within a different subspace. These
|
|
pointers are represented as a structure index from the beginning of
|
|
the appropriate subspace. */

In GDB, this symbol record is unnecessary,

|
|
* start up and run more efficiently. Some of the tasks
|
|
* performed by PXDB are:
|
|
*
|
|
* o Remove duplicate global type and variable information
|
|
* from the GNTT,
|
|
*
|
|
* o Append the GNTT onto the end of the LNTT and place both
|
|
* back in the LNTT section,
|
|
*
|
|
* o Build quick look-up tables (description follows) for
|
|
* files, procedures, modules, and paragraphs (for Cobol),
|
|
* placing these in the GNTT section,
|
|
*
|
|
* o Reconstruct the header appearing in the header section
|
|
* to access this information.
|
|
*
|
|
* The "quick look-up" tables are in the $GNTT$ sub-space, in
|
|
* the following order:
|
|
*
|
|
* Procedures -sorted by address
|
|
* Source files -sorted by address (of the
|
|
* generated code from routines)
|
|
* Modules -sorted by address
|
|
* Classes -<unsorted?>
|
|
* Address Alias -sorted by index <?>
|
|
* Object IDs -sorted by object identifier
|
|
*
|
|
* Most quick entries have (0-based) indices into the LNTT tables to
|
|
* the full entries for the item it describes.
|
|
*
|
|
* The post-PXDB header is in the $HEADER$ sub-space. Alas, it
|
|
* occurs in different forms, depending on the optimization level
|
|
* in the compilation step and whether PXDB was run or not. The
|
|
* worst part is the forms aren't self-describing, so we'll have
|
|
* to grovel in the bits to figure out what kind we're looking at
|
|
* (see hp_get_header in hp-psymtab-read.c).
