The object module disassembler,
omd
, is a useful debugging tool that provides a copy of the assembler code generated for a C or C++ program. If the object module is created with a line number-offset table (that is, if the compiler
option
-l
is in effect), then the source code is merged with the assembler instructions.
Using omd |
The object module disassembler can be invoked either directly or by the
sascc370
or
sasCC370
compiler driver.
The following syntax is used to invoke
omd
directly:
omd [-v] object-filename source-filename
The object-filename argument specifies the name of a compiled object file, and the source-filename argument specifies the name of the source file
used to compile the object. The
-v
option is specified to generate a verbose listing.
The output from the object module disassembler is directed to standard output when
omd
is invoked directly. A copy of the source code is merged with the disassembler listing to enable you to associate the assembler instructions with the source. If you specify the
-v
option, the listing will include a relocation dictionary,
a line number-offset table, and an extended name mapping table.
The
-S
option is used to invoke
omd
from the compiler driver. For example, the following command could be entered to compile the file named myfile.c and generate a
.omd
listing file:
sascc370 -S myfile.cor
sasCC370 -S myfile.cxx
In these cases, the object module disassembler listing would be written to
myfile.omd
.
