This test makes sure that flang's runtime does not depend on the C++ runtime
library. It tries to link this simple file against libFortranRuntime.a with
a C compiler.
REQUIRES: c-compiler
RUN: %cc -std=c99 %s -I%include %libruntime %libdecimal -lm -o /dev/null
#include "flang/Runtime/entry-names.h"
#include <stdint.h>
Manually add declarations for the runtime functions that we want to make sure
we're testing. We can't include any headers directly since they likely contain
C++ code that would explode here.
struct Descriptor;
double RTNAME(CpuTime)();
void RTNAME(ProgramStart)(int, const char *[], const char *[]);
int32_t RTNAME(ArgumentCount)();
int32_t RTNAME(ArgumentValue)(
int32_t, const struct Descriptor *, const struct Descriptor *);
int64_t RTNAME(ArgumentLength)(int32_t);
int main() {
double x = RTNAME(CpuTime)();
RTNAME(ProgramStart)(0, 0, 0);
int32_t c = RTNAME(ArgumentCount)();
int32_t v = RTNAME(ArgumentValue)(0, 0, 0);
int32_t l = RTNAME(ArgumentLength)(0);
return x + c + l;
