-change-addresses incr

-adjust-vma incr

Change the VMA and LMA addresses of all sections, as well as the start address, by adding

incr. Some object ﬁle formats do not permit section addresses to be changed arbitrarily. Note

that this does not relocate the sections; if the program expects sections to be loaded at a certain

address, and this option is used to change the sections such that they are loaded at a different

address, the program may fail.

-change-section-address section{=,+,-}val

-adjust-section-vma section{=,+,-}val

Set or change both the VMA address and the LMA address of the named section. If = is used,

the section address is set to val. Otherwise, val is added to or subtracted from the section

address. See the comments under -change-addresses, above. If section does not exist in

the input ﬁle, a warning will be issued, unless -no-change-warnings is used.

-change-section-lma section{=,+,-}val

Set or change the LMA address of the named section. The LMA address is the address where

the section will be loaded into memory at program load time. Normally this is the same as the

VMA address, which is the address of the section at program run time, but on some systems,

especially those where a program is held in ROM, the two can be different. If = is used, the

section address is set to val. Otherwise, val is added to or subtracted from the section address.

See the comments under -change-addresses, above. If section does not exist in the input

ﬁle, a warning will be issued, unless -no-change-warnings is used.

-change-section-vma section{=,+,-}val

Set or change the VMA address of the named section. The VMA address is the address where

the section will be located once the program has started executing. Normally this is the same as

the LMA address, which is the address where the section will be loaded into memory, but on

some systems, especially those where a program is held in ROM, the two can be different. If = is

used, the section address is set to val. Otherwise, val is added to or subtracted from the section

address. See the comments under -change-addresses, above. If section does not exist in

the input ﬁle, a warning will be issued, unless -no-change-warnings is used.

-change-warnings

-adjust-warnings

If -change-section-address or -change-section-lma or -change-section-vma is

used, and the named section does not exist, issue a warning. This is the default.

-no-change-warnings

-no-adjust-warnings

Do not issue a warning if -change-section-address or -adjust-section-lma or

-adjust-section-vma is used, even if the named section does not exist.

-set-section-flags section=flags

Set the ﬂags for the named section. The flags argument is a comma separated string of ﬂag

names. The recognized names are alloc, contents, load, noload, readonly, code, data,

rom, share, and debug. You can set the contents ﬂag for a section which does not have con-

tents, but it is not meaningful to clear the contents ﬂag of a section which does have contents-

just remove the section instead. Not all ﬂags are meaningful for all object ﬁle formats.
