@cindex options for TIC6X
|
|
|
|
@table @code
|
|
|
|
@cindex @code{-march=} command line option, TIC6X
|
|
@item -march=@var{arch}
|
|
Enable (only) instructions from architecture @var{arch}. By default,
|
|
all instructions are permitted.
|
|
|
|
The following values of @var{arch} are accepted: @code{c62x},
|
|
@code{c64x}, @code{c64x+}, @code{c67x}, @code{c67x+}, @code{c674x}.
|
|
|
|
@cindex @code{-matomic} command line option, TIC6X
|
|
@cindex @code{-mno-atomic} command line option, TIC6X
|
|
@item -matomic
|
|
@itemx -mno-atomic
|
|
Enable or disable the optional C64x+ atomic operation instructions.
|
|
By default, they are enabled if no @option{-march} option is given, or
|
|
if an architecture is specified with @option{-march} that implies
|
|
these instructions are present (currently, there are no such
|
|
architectures); they are disabled if an architecture is specified with
|
|
@option{-march} on which the instructions are optional or not
|
|
present. This option overrides such a default from the architecture,
|
|
independent of the order in which the @option{-march} or
|
|
@option{-matomic} or @option{-mno-atomic} options are passed.
|
|
|
|
@cindex TIC6X big-endian output
|
|
@cindex TIC6X little-endian output
|
|
@cindex big-endian output, TIC6X
|
|
@cindex little-endian output, TIC6X
|
|
@item -mbig-endian
|
|
@itemx -mlittle-endian
|
|
Generate code for the specified endianness. The default is
|
|
little-endian.

@section TIC6X Syntax
|
|
|
|
@cindex line comment character, TIC6X
|
|
@cindex TIC6X line comment character
|
|
The presence of a @samp{;} on a line indicates the start of a comment
|
|
that extends to the end of the current line. If a @samp{#} or
|
|
@samp{*} appears as the first character of a line, the whole line is
|
|
treated as a comment.
|
|
|
|
@cindex line separator, TIC6X
|
|
@cindex statement separator, TIC6X
|
|
@cindex TIC6X line separator
|
|
The @samp{@@} character can be used instead of a newline to separate
|
|
statements.
|
|
|
|
Instruction, register and functional unit names are case-insensitive.
|
|
@command{@value{AS}} requires fully-specified functional unit names,
|
|
such as @samp{.S1}, @samp{.L1X} or @samp{.D1T2}, on all instructions
|
|
using a functional unit.
|
|
|
|
For some instructions, there may be syntactic ambiguity between
|
|
register or functional unit names and the names of labels or other
|
|
symbols. To avoid this, enclose the ambiguous symbol name in
|
|
parentheses; register and functional unit names may not be enclosed in
|
|
parentheses.

@section TIC6X Directives
|
|
|
|
@cindex machine directives, TIC6X
|
|
@cindex TIC6X machine directives
|
|
|
|
Directives controlling the set of instructions accepted by the
|
|
assembler have effect for instructions between the directive and any
|
|
subsequent directive overriding it.
|
|
|
|
@table @code
|
|
|
|
@cindex @code{.arch} directive, TIC6X
|
|
@item .arch @var{arch}
|
|
This has the same effect as @option{-march=@var{arch}}.
|
|
|
|
@cindex @code{.atomic} directive, TIC6X
|
|
@cindex @code{.noatomic} directive, TIC6X
|
|
@item .atomic
|
|
@itemx .noatomic
|
|
These have the same effects as @option{-matomic} and
|
|
@option{-mno-atomic}.
|
|
|
|
@cindex @code{.nocmp} directive, TIC6X
|
|
@item .nocmp
|
|
Disallow use of C64x+ compact instructions in the current text
|
|
section.
|
|
|
