Fixes for arm-none-eabi-g++ #1045

Closed matgla closed 1 month ago

matgla commented 3 months ago

Typeid cannot be used when -fno-rtti is used. Fixed compilation of generated sources on arm-none-eabi-g++ 13.1.

Hi, I just wanted to raise issue that fix is necessary for -fno-rtti + -fno-exception builds. Usage of __PRETTY_FUNCTION and MSVC FUNCSIG__ is a little bit hacky I think, so maybe it's better to print just exception without type.

arm-none-eabi-g++ also fails on std::string to const char* conversion.

Gotbolt link with example usage compile time type_name : https://godbolt.org/z/75fnc5Krq

Real use example: 09:47:22.2417 [INFO] uart0: [host: 81.23ms (+1.83ms)|virt: 0.2ms (+0.2ms)] Type safety violation: Throw exception (-fno-exception) with type "std::error_condition&&" and the message "'fopen' attempt failed"
