dtrace/fbt: fix return probe arguments on arm

2020-07-21T07:41:36Z

arg0 should be an offset of the return point within the function, arg1 should be the return value. Previously the return probe had arguments as if for the entry probe. Tested on armv7. andrew noted that the same problem seems to be present on arm64, mips, and riscv. I am not sure if I will get around to fixing those. So, platform users or anyone looking to make a contribution please be aware of this opportunity. Reviewed by: markj MFC after: 1 week Differential Revision: https://reviews.freebsd.org/D25685

assym is only to be included by other .s files, and should never actually be assembled by itself. Reviewed by: imp, bdrewery (earlier) Sponsored by: The FreeBSD Foundation Differential Revision: https://reviews.freebsd.org/D14180

Make the second argument of dtrace_invop() a trapframe pointer.

2016-04-17T23:08:47Z

Currently this argument is a pointer into the stack which is used by FBT to fetch the first five probe arguments. On all non-x86 architectures it's simply the trapframe address, so this change has no functional impact. On amd64 it's a pointer into the trapframe such that stack[1 .. 5] gives the first five argument registers, which are deliberately grouped together in the amd64 trapframe definition. A trapframe argument simplifies the invop handlers on !x86 and makes the x86 FBT invop handler easier to understand. Moreover, it allows for invop handlers that may want to modify the register set of the interrupted thread.

Remove unused variables dtrace_in_probe and dtrace_in_probe_addr.
