data.o(.data)
@end smallexample
To refine the sections that are included based on the section flags
of an input section, INPUT_SECTION_FLAGS may be used.
Here is a simple example for using Section header flags for ELF sections:
@smallexample
@group
SECTIONS @{
.text : @{ INPUT_SECTION_FLAGS (SHF_MERGE & SHF_STRINGS) *(.text) @}
.text2 : @{ INPUT_SECTION_FLAGS (!SHF_WRITE) *(.text) @}
@}
@end group
@end smallexample
In this example, the output section @samp{.text} will be comprised of any
input section matching the name *(.text) whose section header flags
@code{SHF_MERGE} and @code{SHF_STRINGS} are set. The output section
@samp{.text2} will be comprised of any input section matching the name *(.text)
whose section header flag @code{SHF_WRITE} is clear.
You can also specify files within archives by writing a pattern
matching the archive, a colon, then the pattern matching the file,
with no whitespace around the colon.
