It would be success for compiling program and execute simulation with no any warning like (TOHOST: XXXX).
The simulation warning will occur during execution the system call (like printf) or floating variable computation. The screenshot shows the warning during the previous two scenarios.
main.c
int add(int a, int b);
int main(int argc, char** argv) {
int res = add(3, 2);
// Simple float variable computation
float a = 1.0;
for(int i = 0; i < 10; i++) {
a += 0.5;
}
return res == 5 ? 0 : -1;
}

There is an another question. Could riscv-mini team provide the some source code (riscv-mini/src/test/resources/) and its corresponding crt.S, syscall.c, util.h, linker sciprt (test.ld).
Hi,
I try to use the test.ld, syscall.c and crt.S from (riscv-tools and checkout to 4635ab67966c763a84f7217bc2c20b65dcabc7ec. Those sources exist in riscv-tests/benchmarks/common/. These two steps follow riscv-mini/build-riscv-tools.sh) for building the custom-bmark.
