STDUMP(1)STDUMP(1)NAMEstdump - dump a file of intermediate-code debugging information
SYNOPSISstdump [-a] [-b] [-c] [-g] [-h] [-i] [-n number] file
DESCRIPTION
When compiling for the old 32-bit ABI (-32), the compilers generate an
intermediate language which is separated into binary instructions and
debugging information, each constituting a separate file. Use stdump to
dump a file containing debugging information which was generated by the
compilers. stdump writes to the standard output. The organization of the
output is simple but the details of the output are complicated. The
detailed output is be defined here. The output of stdump is subject to
change and one should not rely on the output format remaining the same
from release to release.
The organization of the output is: for each source file represented in
file there may be auxiliary-symbols, local-symbols, a file-indirect-
table, optimization-entries, procedures, and line-numbers; there is only
one externals-table and one dense-number-table in file.
By default, stdump prints all information about all sections of the
debugging information. The options (described below) restrict the output
to the selected sections.
The file may be an object file (such as produced by cc -c) or an
executable file (such as produced by ld(1) or cc(1)) or a debugging
information file (which may be produced as described below).
Normally, debugging information files (and instruction files) are placed
in /tmp and removed after each compilation. Use the -keep option to cc,
or f77(1) to force the compiler to preserve these files in the target
directory. When this switch is used, the compilation of file.x (where x
is c for C or f for FORTRAN, for example) will produce the intermediate
files file.B (instructions) and file.T (debugging information). The
latter file (file.T) may be used as input to stdump.
The following options are recognized:
-a Print the dense number table. This section is empty for object
and executable files.
-b Print the externals table.
-c Print the local debugging symbols. The source file name is
printed here.
-g Print the auxiliaries table. This table has encoded in it in a
complex way the actual data types of all the data in the symbols.
The local-symbol and externals table sections show this data
expanded into semi-readable text.

STDUMP(1)STDUMP(1)-h Print the line table. One source line number per 32-bits of
executable code.
-i Print the File Indirect Table.
-n number
Print information about only the source file whose number is
given. Files are numbered sequentially starting with zero.
FILES
/tmp/ctmstaxxxxx default name of debugging information file for process
id xxxxx
file.T name of debugging information file created by the -keep
option
/usr/bin/stdump debugging information dump program

One cannot use stdump to display the debugging information of 64-bit (-
64) or new 32bit ABI (-n32) object files. Use dwarfdump(1) instead.
To see the linking information, use elfdump(1) instead of stdump.
