Problem with std::function

[panchev68]

To Reproduce:
I'm trying to convert a project written in IAR from 15 years ago. But I'm having some problems with the IAR extension for VS Code.
This compiles, but the editor gives an error :no operator "=" matches these operandsC/C++(349)
Maybe the error is mine!

Environment:

• OS: [Windows]
• Embedded Workbench: [Arm]
• Embedded Workbench version: EWARM 8.22.1
• VSC Extension version: 1.32.1

Additional context:

error:

PS: I installed some outdated extension (pluyckx.iar-vsc) and this problem is gone!

Thanks for the bug report!

The intellisense engine (from the C/C++ extension) does not understand IAR language extensions. In this case, our __data keyword is used in the definition of std::decay, which causes std::function and std::invoke to be unable to match function types correctly.

To fix this, you can add the following to the "Iar-build: Defines" setting for this extension:

__DATA_MEMORY_LIST1__()=

This will cause the preprocessor to remove the problematic parts of the std::decay definition. I'll also commit a fix to make this setting apply by default.
