hip headers generate a lot of warnings

[sthibaul]

Hello,

Just compiling this:

#include <hip/hip_runtime.h>
#include <hip/hip_runtime_api.h>

int main(void) {
	return 0;
}

with

gcc test.c -o test -Wall -Wextra $(hipconfig -C)

generates a lot of warnings:

this is polluting the build logs of hip applications

@sthibaul, Thanks for reporting it. I could see a total of 10 warnings, out of that 8 are deprecation warnings which Cuda has added for those APIs. Unfortunately, we have to live with those warnings until Cuda drops them. The remaining two warnings are genuine misses which should be addressed in the next release.

BTW, there are ways to suppress unwanted warnings let me know if you need any information for the same.
