Is there an attribute I can use to make a function as an interrupt handler ?

[Karim Hasebou]

I am porting an RTOS for RISC - V32 and when I writing a macro for interrupt handling I tried using the naked attribute to stop gcc from generating any code in that method but the compiler issued a warning attribute ignored. 

So is their an alternative attribute I can use ?

As in am looking for a way to stop the compiler from generating prolog and epilog code code

See
https://github.com/riscv/riscv-gcc/pull/117

It will probably end up on the riscv-next branch within a week, and
then in the FSF GCC tree for the gcc-8 release in the spring.

See also the issue you opened
https://github.com/riscv/riscv-gnu-toolchain/issues/313
which has a pointer to the above patch.

If you don’t wanna wait, you can also use __attribute__((optimize("O3"))) or #pragma GCC optimize (3).
