Macro Assembler
Note that even though the two blocks of code in the text psect are separated by a block in the rbss
psect, the two text psect blocks will be contiguous when loaded by the linker. In other words, the
incf _fred instruction will be followed by the clrf instruction in the final output. The actual
location in memory of the text and rbss psects will be determined by the linker.
psect.
4.3.8 Assembler Directives
Assembler directives, or pseudo-ops, are used in a similar way to instruction mnemonics, but either
do not generate code, or generate non-executable code, i.e. data bytes. The directives are listed in
Table 4.5, and are detailed below.
4.3.8.1 GLOBAL
GLOBAL declares a list of symbols which, if defined within the current module, are made public. If
the symbols are not defined in the current module, it is a reference to symbols in external modules.
Example:
4.3.8.2 END
END is optional, but if present should be at the very end of the program. It will terminate the
assembly and not even blank lines should follow this directive. If an expression is supplied as an
argument, that expression will be used to define the start address of the program. Whether this is of
any use will depend on the linker. Example:
Code or data that is not explicitly placed into a psect will become part of the default (unnamed)
PSECT text0,class=CODE,delta=2
clear_fred
