6.2.23 Section Group Specification (-gr)
Multiple sections are linked to create a group according to the purpose of the user and
a group name is given to the group.
By using this group name when specifying the section allocation, multiple sections can
be handled as one group.
■ Section Group Specification (-gr)
[Format]
-gr = [ / ] [ , … ]
[Parameters]
Generic name of multiple sections to be grouped
Describes section names to be grouped.
The wild card can be used.
When specifying multiple names, link them with the + symbol.
code, data, stack, const, IO
[Description]
Sections to be grouped and the order of section allocation in the group are specified.
The order of section allocation follows the order described in the parameters.
Each group name must be a unique name which does not overlap with the section names and other
group names.
A section that belongs to one group must not belong to another group.
When using the wild card, indicate it using double quotation marks("). Do not use double quotation
marks (") in an option file.
[Example 1]
flnk911s *.obj -o ap.abs -ro ROM=0xC1000/0xCFFFF
-ra RAM=0x1000/0x13FF...-gr romG=P+code+text1 -sc romG=ROM,D=RAM ...
When using the grouping option, the whole group can be represented by its group name instead of
specifying any number of section names.
[Example 2]
flnk911s *.obj -o ap.abs -gr cdgrp=*/code -sc cdgrp=0xC1000
All sections whose content type is code are linked to a group and the group name cdgrp is given to the
group. Then the group is allocated to the address 0xC1000 using the -sc option.
