Converter options

3.1

No warnings

When the -noWarn option is used warnings aren't reported. This option is useful when

converting many file and only the conversion errors are important. For more details about

warnings, see the Chapter 5: Limitations.

3.2

Preprocessing

When the -pp option is used the file is preprocessed before being converted. The

preprocessing is executed using the ccetpu compiler. In the preprocessing stage all the

macros are analyzed and replaced with their values. Only after preprocessing the file, its

conversion starts. This option is useful with c files that use macros in their inline assembly

sections. The converter will not recognize the macros without preprocessing the file first and

therefore the option is necessary in such cases.

Note:

Using this option will cause white space and new line modifications in the file. Spaces and

new lines might be added or removed during the preprocessing stage, and macros will be

replaced with their values, but the actual content of the file will not be modified.

When using this option, the input file is passed through the ccetpu C compiler. Therefore, it

has to follow eTPU c language rules, for example the file must end with a ".c" extension.

Example of the -pp option:

etpu_asm_converter.exe -pp -c c_input.c out.txt

3.3

Debug information

When the -debugE option is used debug information is printed in case of errors. This

information may be useful in order to find Byte Craft syntax errors. Note that this option was

created for development purposes and therefore in many cases the provided information will

probably not be clear or helpful.

This option is mostly useful in chan instruction.

For example:

etpu_asm_converter.exe -m -debugE

chan set flag2.

error in line 3: syntax error, unexpected FREE_TEXT,

expecting FLAG0 or FLAG1.
