While testing gmp on the x86_64 target I discovered a fuction pointer bug.
(reuse in directory tests/mpf)
The code:
#include <stdio.h>
typedef int (*func) (int);
func allfunc[] = { putchar };
int main(void) {
printf ("%d\n", allfunc[0] == putchar);
return 0;
}
prints 0 on x86_64, macos and riscv (all other targets (i386, arm,
arm64, win32, win64) print 1).
There seems to be something wrong with relocation.
The allfunc[0] points to the got table. The putchar to the externel symbol.
