Texas Instruments TMS34010 User Manual

Invocation and Operation of the TMS34010 C Compiler
*
An example:
**********************************************
* AS - EXPRESSION FREE *
* A7 - USER VARIABLE FREE SYMBOL; -ABC *
* A9 - USER REGISTER USED *
**********************************************
Instructs GSP.CG to generate code which runs on certain preproduction
units
of the TMS3401 O. This option is not needed when compiling code
·for production units of the TMS3401 O. Certain instructions not available
in preproduction units are not used when this option is invoked.
3.3.3 Input Requirements
GSPCG input must be the intermediate file produced by the parser. The out-
put'of the parser is fed, without modification, directly to the GSPCG.
3.3.4 GSPCG Output
GSPCG converts the intermediate file generated by the parser into assembly
lanQuage
source code suitable for input to the assembler or for modification
with a text editor. This code is reentrant, relocatable, and can be stored in
ROM.
3.4 Batch Execution of the C Compiler
3-6
The C compiler package contains the batch file GSPC.BAT, which executes
the three phases
of the compiler and the assembler. This batch file is invoked
as follows:
where:
input file
Example:
is the name of the C source file. The default extension of this
file is .c. A prompt appears if no file name is given.
.9.2E.£ PROGRAM
This example uses PROGRAM.C as the C source file and generates PRO-
GRAM.ASM as the assembly file and PROGRAM.OBJ as the object file.
PROGRAM.OBJ
can be used as input to the linker, GSPLNK.
