+Locate a section in the output file at the absolute

+@var{org} must be a single hexadecimal integer;

+@samp{0x} usually associated with hexadecimal values. @emph{Note:} there

followed by a series of symbol assignments and output section
descriptions enclosed in curly braces.
-The first line in the above example sets the special symbol @samp{.},
-which is the location counter. If you do not specify the address of an
-output section in some other way (other ways are described later), the
-address is set from the current value of the location counter. The
-location counter is then incremented by the size of the output section.
-
The first line inside the @samp{SECTIONS} command of the above example
sets the value of the special symbol @samp{.}, which is the location
counter. If you do not specify the address of an output section in some
match all files except the ones specified in the EXCLUDE_FILE list. For
example:
@smallexample
-(*(EXCLUDE_FILE (*crtend.o, *otherfile.o) .ctors))
+(*(EXCLUDE_FILE (*crtend.o *otherfile.o) .ctors))
@end smallexample
-will cause all .ctors sections from all files except crtend.o and otherfile.o
-to be included.
+will cause all .ctors sections from all files except @file{crtend.o} and
+@file{otherfile.o} to be included.
There are two ways to include more than one section:

true of, for example, S-records, the value will be stored in the
endianness of the first input object file.
+Note - these commands only work inside a section description and not
+between them, so the following will produce an error from the linker:
+@smallexample
+SECTIONS @{@ .text : @{@ *(.text) @}@ LONG(1) .data : @{@ *(.data) @}@ @}@
