Directives

BL51 Linker directives are entered on the command line after the output file. Multiple directives must be separated by at least one empty space. Each directive may be entered only once on the command line. If a directive is entered twice, the linker generates an error.

The following table describes all BL51 Linker directives.

NODEFAULTLIBRARY	Disables automatic inclusion of run-time library routines.
NOINDIRECTCALL	Disables bank switching code for indirectly called functions.
NOJMPTAB	Disables generation of the code banking jump table.
NOLINES	Excludes line number information from the listing file and object file.
NOMAP	Excludes the memory map from the listing file.
NOOVERLAY	Disables data segment overlaying.
NOPRINT	Disables generation of the listing (MAP) file.
