Chapter 6 Using Linker
98 Command Options
Functional description
This option specifies the starting address for the specified section. It changes the starting address for all
sections in all relocatable object files specified to the right of this option.
The linker checks these specifications for overlap between sections.
Rules of use
This option is specified with the hyphen (-) option specification character, followed by the upper-case
letter 'T'.
Section may be specified by section name, section attribute or both. To specify a section attribute,
precede the name of the attribute with the character @. Multiple sections may be specified together as a
comma-delimited list.
The starting address is given in hexadecimal. In -T@CODE=abc, ABC is a hexadecimal number.
ld103 -T@CODE=80000000 -T@DATA=0 prog1.rf prog2.rf
ld103 -T_TEXT,_CONST=80000000 main.rf -T_TEXT, _CONST=80002000
sub.rf
ld103 -T_TEXT@CODE=80000000 test1.rf test2.rf
Be careful with the specification order for files since that order is the order in which the linker merges
sections.
Section layout rules
The sections are merged according to the following rules.
1. Sections appearing with -T option specifications are assigned to the specified addresses.
2. The remaining sections with no such specifications are arranged with the CODE sections proceed-
ing the DATA sections using the following rules.
a Sections with the same name and same attribute are merged after the sections with the highest
address.
b Sections with the same attribute are merged after the sections with the highest address.
c Remaining sections are merged after the sections with the highest address.
Figure 6-2 illustrates the process.
