CCSv5 and C2xLP Source Compatibility

MKo

Hi,

we're currently moving a (mainly assembly) project from C240x to F2803x by using the C2x compatibility mode. However, when compiling C-Code the compiler issues a lot of warnings like

WARNING! at line 163: [E0011] Expecting C2XLP direct addressing mode (@@) MOV T,*-SP[3] ; [CPU_] |60|

WARNING! at line 21627: [W0000] Constant parsed as an octal number .dwcfi cfa_offset, 0

Compiler options are:

-v28 -mt -ml -g --c2xlp_src_compatible --cla_support=cla0 --asm_remarks --preproc_with_compile --preproc_dependency="[...]" --obj_directory="[...]" $FILE

Thus can't the compiler generate C2x intermediate assembly code from C which can then be assembled and linked to our existing assembly files and run together in C2x compatibility mode? Or am I simply missing a compiler switch? Or can I safely ignore these warnings?

Thanks!

Don't use the switch --c2xlp_src_compatible when compiling C code.

Thanks and regards,

Thanks, but how to do this in CCSv5? This option can be either on or off, however, I've got a mixed C28-C and C24-asm project and couldn't find a way to turn this on only for asm. Thanks again.

You can set file specific options in CCS. So you can disable that option at the project level, and then for each assembly source file, right-click on the file, go to Build Options and set the option.
