Chapter 38. TIC54X Dependent Features

.break

terminates the loop so that assembly begins after the

.endloop

directive. The optional

condition

will cause the loop to terminate only if it evaluates to zero.

macro_name .macro [param1][,...param_n]

[.mexit]

.endm

See the section on macros for more explanation (Section 38.10 Macros.

.mlib "filename" | filename

Load the macro library

filename

.

filename

must be an archived library (BFD ar compatible)

of text files, expected to contain only macro definitions. The standard include search path is used.

.mlist

.mnolist

Control whether to include macro and loop block expansions in the listing output. Ignored.

.mmregs

Define global symbolic names for the 'c54x registers. Supposedly equivalent to executing

.set

directives for each register with its memory mapped value, but in reality is provided only for

compatibility and does nothing.

.newblock

This directive resets any TIC54X local labels currently defined. Normal

as

local labels are unaf 

fected.

.option option_list

Set listing options. Ignored.

.sblock "section_name" | section_name [,"name_n" | name_n]

Designate

section_name

for blocking. Blocking guarantees that a section will start on a page

boundary (128 words) if it would otherwise cross a page boundary. Only initialized sections may

be designated with this directive. See also Section 38.2 Blocking.

.sect "section_name"

Define a named initialized section and make it the current section.

symbol .set "value"

symbol .equ "value"

Equate a constant

value

to a

symbol

, which is placed in the symbol table.

symbol

may not be

previously defined.

.space size_in_bits

.bes size_in_bits

Reserve the given number of bits in the current section and zero fill them. If a label is used with

.space

, it points to the first word reserved. With

.bes

, the label points to the last word reserved.
