This patch fixes the following problems: - Missing includes in several files leading to implicit function declarations. - Missing prototype for bpf_trace_printk in bpf-helpers.h - The simulator bitsize was set to 32 bits, causing truncation of the program counter. Tested in bpf-unknown-none. sim/ChangeLog: 2020-09-03 Jose E. Marchesi <jose.marchesi@oracle.com> * bpf/bpf.c: Include bpf-helpers.h. * bpf/bpf-helpers.h: Provide a prototype for bpf_trace_printk. * bpf/configure.ac: Set simulator bitsize to 64. * bpf/configure (includedir): Regenerate. * bpf/sim-if.c: Include stdlib.h. * bpf/traps.c: Likewise.
