stdbool.h ?

stdbool.h ?

[Emmanuel Blot]

Hi,

I’m not able to find stdbool.h header file in newlib source code 
(neither in 3.1 tarball nor in git repository).

As I understand that newlib in compliant with C99 (am I wrong?), should 
not it be part of the newlib base code, as stdint.h is?

Thanks,
Emmanuel.

Hi Emmanuel,

That's usually provided by gcc.

./lib/gcc/target/version/include/stdbool.h

Cheers,
Jon

I’m using LLVM :)
I just discovered that the host’s stdbool.h was used up to now - which 
is fortunately target agnostic.

GCC also provides its own stdint.h (including either an external 
stdint.h or its own), so I’m surprised the behaviour is different with 
stdbool.h.
As I understand it - maybe I’m wrong - stdbool.h is part of the C 
Standard Library, so should not it be part of the newlib C 
implementation as well? I know the boundary between the compiler and the 
C library is somewhat tricky, but it is kind of weird stdint.h and 
stdbool.h are somewhat handled differently.

Thanks,
Emmanuel.
