Linker and Utilities
5.9.5 -Dclass=delta
This option allows the delta value for psects that are members of the specified class to be defined.
The delta value should be a number and represents the number of bytes per addressable unit of
objects within the psects. Most psects do not need this option as they are defined with a delta value.
5.9.6 -Dsymfile
Use this option to produce an old-style symbol file. An old-style symbol file is an ASCII file, where
each line has the link address of the symbol followed by the symbol name.
5.9.7 -Eerrfile
Error messages from the linker are written to standard error (file handle 2). Under DOS there is no
convenient way to redirect this to a file (the compiler drivers will redirect standard error if standard
output is redirected). This option will make the linker write all error messages to the specified file
instead of the screen, which is the default standard error destination.
5.9.8 -F
Normally the linker will produce an object file that contains both program code and data bytes, and
symbol information. Sometimes it is desired to produce a symbol-only object file that can be used
again in a subsequent linker run to supply symbol values. The -F option will suppress data and code
bytes from the output file, leaving only the symbol records.
is contained in different memory devices located at different addresses. The files for one device are
compiled using this linker option to produce a symbol-only object file; this is then linked with the
files for the other device. The process can then be repeated for the other files and device.
5.9.9 -Gspec
When linking programs using segmented, or bank-switched psects, there are two ways the linker
can assign segment addresses, or selectors, to each segment. A segment is defined as a contiguous
group of psects where each psect in sequence has both its link and load address concatenated with
the previous psect in the group. The segment address or selector for the segment is the value derived
when a segment type relocation is processed by the linker.
ment by the relocation quantum of the segment, which is based on the reloc= flag value given to
psects at the assembler level. This is appropriate for 8086 real mode code, but not for protected mode
This option can be used when producing more than one hex file for situations where the program
By default the segment selector will be generated by dividing the base load address of the seg-
