Macro Assembler
psect, and some data being placed in the rbss psect.
Note that even though the two blocks of code in the text psect are separated by a block in the bss
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 ouptut. The actual
location in memory of the text and bss 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:
The following is an example showing some executable instructions being placed in the text
Code or data that is not explicitly placed into a psect will become part of the default (unnamed)
