I noticed a little diff when re-generating the configure file in this
directory.
sim/ChangeLog:
* bpf/configure: Re-generate.
Change-Id: Ieb26be2cc1be8108d4b08387255f45b57f288171
The div and mod eBPF instructions are unsigned, but the semantic
specification for the simulator incorrectly used signed operators.
Correct them to unsigned versions, and correct the ALU tests in
the simulator (which incorrectly assumed signed semantics).
Tested in bpf-unknown-none.
cpu/ChangeLog:
2020-09-08 David Faust <david.faust@oracle.com>
* bpf.cpu (define-alu-instructions): Correct semantic operators
for div, mod to unsigned versions.
sim/ChangeLog:
2020-09-08 David Faust <david.faust@oracle.com>
* bpf/sem-be.c: Regenerate.
* bpf/sem-le.c: Likewise.
sim/testsuite/ChangeLog:
2020-09-08 David Faust <david.faust@oracle.com>
* sim/bpf/alu.s: Correct div and mod tests.
* sim/bpf/alu32.s: Likewise.
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.
