@cindex Meta architectures
|
|
|
|
The Imagination Technologies Meta architecture is implemented in a
|
|
number of versions, with each new version adding new features such as
|
|
instructions and registers. For precise details of what instructions
|
|
each core supports, please see the chip's technical reference manual.
|
|
|
|
The following table lists all available Meta options.
|
|
|
|
@table @code
|
|
@item -mcpu=metac11
|
|
Generate code for Meta 1.1.
|
|
|
|
@item -mcpu=metac12
|
|
Generate code for Meta 1.2.
|
|
|
|
@item -mcpu=metac21
|
|
Generate code for Meta 2.1.
|
|
|
|
@item -mfpu=metac21
|
|
Allow code to use FPU hardware of Meta 2.1.

@subsection Special Characters
|
|
|
|
@cindex line comment character, Meta
|
|
@cindex Meta line comment character
|
|
@samp{!} is the line comment character.
|
|
|
|
@cindex line separator, Meta
|
|
@cindex statement separator, Meta
|
|
@cindex Meta line separator
|
|
You can use @samp{;} instead of a newline to separate statements.
|
|
|
|
@cindex symbol names, @samp{$} in
|
|
@cindex @code{$} in symbol names
|
|
Since @samp{$} has no special meaning, you may use it in symbol names.
|
|
|
|
@node Meta-Regs
|
|
@subsection Register Names
|
|
|
|
@cindex Meta registers
|
|
@cindex registers, Meta
|
|
Registers can be specified either using their mnemonic names, such as
|
|
@samp{D0Re0}, or using the unit plus register number separated by a @samp{.},
|
|
such as @samp{D0.0}.
