Operation
5.9.1 Numbers in linker options
Several linker options require memory addresses or sizes to be specified. The syntax for all these is
similar. By default, the number will be interpreted as a decimal value. To force interpretation as a
hex number, a trailing H should be added, e.g. 765FH will be treated as a hex number.
5.9.2 -Aclass=low-high,...
Normally psects are linked according to the information given to a -P option (see below) but some-
times it is desired to have a class of psects linked into more than one non-contiguous address range.
This option allows a number of address ranges to be specified for a class. For example:
specifies that the class CODE is to be linked into the given address ranges. Note that a contribution
to a psect from one module cannot be split, but the linker will attempt to pack each block from each
module into the address ranges, starting with the first specified.
repeat count, e.g.
specifies that there are 16 contiguous ranges each 64k bytes in size, starting from zero. Even though
the ranges are contiguous, no code will straddle a 64k boundary. The repeat count is specified as the
character x or * after a range, followed by a count.
5.9.3 -Cx
These options allow control over the call graph information which may be included in the map file
produced by the linker. The -CN option removes the call graph information from the map file. The
-CC option only include the critical paths of the call graph. A function call that is marked with a * in
a full call graph is on a critical path and only these calls are included when the -CC option is used.
A call graph is only produced for processors and memory models that use a compiled stack.
5.9.4 -Cpsect=class
This option will allow a psect to be associated with a specific class. Normally this is not required on
the command line since classes are specified in object files.

Where there are a number of identical, contiguous address ranges, they may be specified with a
-ACODE=1020h-7FFEh,8000h-BFFEh
-ACODE=0-FFFFhx16
