Linker and Utilities
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
or some bank-switched arrangements. In this instance the -G option is used to specify a method for
calculating the segment selector. The argument to -G is a string similar to:
where A represents the load address of the segment and / represents division. This means "Take the
load address of the psect, divide by 10 hex, then subtract 4". This form can be modified by substi-
tuting N for A, * for / (to represent multiplication), and adding rather than subtracting a constant.
The token N is replaced by the ordinal number of the segment, which is allocated by the linker. For
example:
means "take the segment number, multiply by 8 then add 4". The result is the segment selector. This
particular example would allocate segment selectors in the sequence 4, 12, 20, ... for the number
of segments defined. This would be appropriate when compiling for 80286 protected mode, where
these selectors would represent LDT entries.
5.7.10 -Hsymfile
This option will instruct the linker to generate a symbol file. The optional argument symfile
specifies a file to receive the symbol file. The default file name is l.sym.
5.7.11 -H+symfile
This option will instruct the linker to generate an enhanced symbol file, which provides, in addition
to the standard symbol file, class names associated with each symbol and a segments section which
lists each class name and the range of memory it occupies. This format is recommended if the code
is to be run in conjunction with a debugger. The optional argument symfile specifies a file to
receive the symbol file. The default file name is l.sym.
5.7.12 -Jerrcount
The linker will stop processing object files after a certain number of errors (other than warnings).
The default number is 10, but the -J option allows this to be altered.
By default the segment selector will be generated by dividing the base load address of the seg-
