Invoking the Tools Individually
2-45 C Compiler Description
tempfile names a temporary file that the code generator creates and
uses. If you do not supply a filename for the temporary file, the
code generator uses the input filename with the extension
.tmp . The code generator deletes this file after using it.
options affect the way the code generator processes the input file.
Each option available for the stand-alone code generator
mode has a corresponding dspcl shell option that performs the
same function.
Table 2 − 7 shows the code generator options, the dspcl shell options, and their
corresponding functions.
Table 2 − 7. Code Generator Options and dspcl Options
dspcg Options dspcl Options Function
− a − ma Assume variables are aliased
− b − mb Disable the noninterruptible RPTK instruction
for moving structures
− g register − r register Reserve global register †
− l − ml Disable optimization for reducing LDPK
instructions
− n − mn Reenable optimizations disabled by symbolic
debugging
− o − g Enable C source level debugging
− q − q Suppress progress messages (quiet)
− r − mr List register use information
− s − ms Optimize for space instead of for speed
− v25 − v25 Enable use of TMS320C2x instructions
− v2xx − v2xx Enable use of TMS320C2xx instructions
− v50 − v50 Enable use of TMS320C5x instructions
− x − mx Avoid ’C5x silicon bugs
− z Retain the input file ‡
†
The − g option tells the code generator that the register named is reserved for global use. See sec-
tion 5.6, Creating Global Register Variables , on page 5-10, for more information.
‡
The − z option tells the code generator to retain the input file (the intermediate file created by the
parser). If you do not specify the − z option, the intermediate file is deleted.
