MC56F84763 compiler -PC-lint plus

BobZgl — Thu, 28 Apr 2022 09:58:42 GMT

MC56F84763 use mwcc56800e-mwasm56800e-mwld56800e to compile project. Whether I can use GNU GCC compiler Tool like arm-none-eabi-gcc-4_7_3 to compiler the project.
Why I want to change to GNU GCC compiler, it is because of that 56800E Tool it is not support for PC-lint Plus

As far I know, there is no GCC version supporting 56800EX cores (used by MC56F84763).
There is only the (previously Metrowerks) NXP toolchain available for it.

Hi,

Because the MC56F800EX only adds the 32bit*32bit =64 bits operation instructions, which is independent part, so there is not dedicated compiler for 56800EX core, the compiler is based on 56800E core.

If you want to tell the compiler to use DSP56800EX core, you can use the compiler option:

7.5.11 -V3
Generates an elf file for 56800EX digital signal controller.
Syntax
-V3

For detailed information, pls refer to above section in MCU_DSC_Compiler.pdf from the directory if you have installed CodeWarrior for MCU ver

.......\CW MCU v11.1\MCU\Help\PDF

Hope it can help you

According to GNU GCC using "gcc -dM -E -xc /dev/null" to print macro expansion, we can get compiler defined macros. What option to use DSP56800x_EABI_Tools to get compiler defined macros?

AFAIK there is no equivalent to those GCC options.

Hi Xiangjun,

It look like 56800/E Digital Signal Controllers doesn't support PC-Lint plus, the problem is that the compiler doesn't provide an option to get the macros that the compiler defines by default.

Do you have any suggestions for static analysis of the MC56F84763 Project completion code
