Bug Summary and Steps to Reproduce
Bug Summary:
If both "compilerPath" and "compileCommands" are present in "c_cpp_properties.json", the former seems to take precedence during IntelliSense analysis. This results in the command line of the file present in compile_commands.json (e.g. -mcpu) to be ignored, leading to missing defines. Removing "compilerPath" results in the command line from compile_commands.json being taken into the account.
This behaviour goes directly against what c_cpp_properties.json reference documents:
If there is a matching entry in compile_commands.json for a file open in the editor, that command line will be used to configure IntelliSense for that file, instead of the other fields of c_cpp_properties.json.
Additionally, the intended behaviour (compile_commands.json overriding other options) was mentioned yesterday in another issue: https://github.com/microsoft/vscode-cpptools/issues/11880#issuecomment-1901003596.
Defining "compilerPath": "", works as a workaround.
Observed behaviour:
"compilerPath" takes precedence over "compileCommands" for populating system/architecture specific defines.
Expected behaviour:
"compileCommands" takes precedence over "compilerPath" for populating system/architecture specific defines.
