| * | sh: Optimise FDE/CIE lookup by using red-black treesMatt Fleming2010-02-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now that the DWARF unwinder is being used to provide perf callstacks unwinding speed is an issue. It is no longer being used in exceptional circumstances where we don't care about runtime performance, e.g. when panicing, so it makes sense improve performance is possible. With this patch I saw a 42% improvement in unwind time when calling return_address(1). Greater improvements will be seen as the number of levels unwound increases as each unwind is now cheaper. Note that insertion time has doubled but that's just the price we pay for keeping the trees balanced. However, this is a one-time cost for kernel boot/module load and so the improvements in lookup time dominate the extra time we spend keeping the trees balanced.

| * | sh: Don't continue unwinding across interruptsMatt Fleming2010-02-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Unfortunately, due to poor DWARF info in current toolchains, unwinding through interrutps cannot be done reliably. The problem is that the DWARF info for function epilogues is wrong. Take this standard epilogue sequence, 80003cc4: e3 6f mov r14,r15 80003cc6: 26 4f lds.l @r15+,pr 80003cc8: f6 6e mov.l @r15+,r14 <---- interrupt here 80003cca: f6 6b mov.l @r15+,r11 80003ccc: f6 6a mov.l @r15+,r10 80003cce: f6 69 mov.l @r15+,r9 80003cd0: 0b 00 rts If we take an interrupt at the highlighted point, the DWARF info will bogusly claim that the return address can be found at some offset from the frame pointer, even though the frame pointer was just restored. The worst part is if the unwinder finds a text address at the bogus stack address - unwinding will continue, for a bit, until it finally comes across an unexpected address on the stack and blows up. The only solution is to stop unwinding once we've calculated the function that was executing when the interrupt occurred. This PC can be easily calculated from pt_regs->pc.

| * | sh: Setup frame pointer in handle_exception pathMatt Fleming2010-02-07
| | | | | | | | | | | | | | | | | | | | | | | | In order to allow the DWARF unwinder to unwind through exceptions we need to setup the frame pointer register (r14). Signed-off-by: Matt Fleming <matt@console-pimps.org> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
| * | sh: Correct the offset of the return address in ret_from_exceptionMatt Fleming2010-02-07
| |/ | | | | | | | | | | | | | | | | | | | | | | | | The address that ret_from_exception and ret_from_irq will return to is found in the stack slot for SPC, not PR. This error was causing the DWARF unwinder to pick up the wrong return address on the stack and then unwind using the unwind tables for the wrong function. While I'm here I might as well add CFI annotations for the other registers since they could be useful when unwinding.
