Compiler/ARM-CGT: Enable Warnings

Part Number: ARM-CGT

Tool/software: TI C/C++ Compiler

What is/are the command line option/s to enable warnings for TI ARM CGT? Like it is e.g., -Wall for gcc.

    Hi,

    I think you just need to make sure you do not have "--no_warnings" in the command line. 

    Please refer to compiler user's guide, section 2.7.1

    I do not use this option. I find it still unlikely that there is nowadays a compiler, that does not give the user arguments at hand to control the number of warnings and the warning levels.

    GCC, LLVM, MSVC all have similar options to achive this.

    Specifcally I am asking this question, as I saw that TI ARM CGT does not warn about wrong enum comparisons (gcc warning would be -Wenum-compare) and so I thought there must be a switch to enable this warning.

    Hi,

    You can try "--check_misra=10.1"

    Also, you can try some static analysis tools.

    MISRA-C checks are not the same as a compiler warning. Furthermore MISRA-C checks in TI ARM CGT are only 2004 and I think this will not change (e2e.ti.com/.../1264504
    I take from these answers here, that enableing warning, or having a list on what TI ARM CGT warns based on some internal compiler configuration is not supported.
    Thanks and best regards.

    Did you go through the documentation compiler user's guide, section 2.7.1

    www.ti.com/.../SPNU151R

    You can try --issue_remarks Issues remarks (non-serious warnings), which are suppressed by default.

    I have not used this myself, but please check if it helps.

    Yes I am using, --issue_remarks, however this has the downside, that --emit_warnings_as_errors does not include the issued remarks.

    Therefore I need to manually add a list of all remarks I want to turn into errors and this list can get quite long.Furthermore I can not find a list on the TI Website, that gives a complete list of all remarks that exist. Could you show me one?

    The TI ARM compiler has no equivalent to gcc -Wall.  To learn how to manage diagnostics in the TI ARM compiler, please search the TI ARM compiler manual for the sub-chapter titled Understanding Diagnostic Messages.

    The existing issue EXT_EP-9948 requests that this list of diagnostics be published.  You are welcome to follow it with the link below in my signature.

    Thanks and regards,
