Code analysis error: Function '__sync_bool_compare_and_swap' could not be resolved [message #1077528]

Code analysis is not able to resolve any of the GCC atomic builtin functions (gcc.gnu.org/onlinedocs/gcc-4.1.2/gcc/Atomic-Builtins.html).

Code example:

bool foo(false);
while(!__sync_bool_compare_and_swap(&foo, false, true)) {}

I have 'Automated discovery of paths and symbols' enabled for 'GCC C++ Compiler' in C/C++ Build -> Discovery Options

Is there something else I'm missing to get these to cleanly resolve?

TIA

Paul,
I have a similar issue, I add the path in to the "preprocessor include path"->Entries.

I hope this works for you..
Regards

I added it manually to:

C/C++ General -> Preprocessor Include Paths -> Entries -> CDT User Setting Entries

and it solved the problem, but is there a way to configure the CDT GCC Built-in Compiler Settings provider to discover these GCC built-in functions automatically?

The same problem. Tried -march key in compiler settings but it didn't work out. Looks a bit weird that your include solves the problem as this built-in function doesn't have any header file to be included.
