Bug #: 14573
Summary: Pass pt_regs to dyninst probe handlers
AssignedTo: [hidden email] ReportedBy: [hidden email] Classification: Unclassified
In order to examine much process state with stapdyn, we're going to need
registers. We should pass a pt_regs* (/usr/include/asm/ptrace.h) as a
parameter to the probe handler.
I believe this can be allocated and prepared via BPatch_register code snippets.
We will probably need to hardcode architecture-specific support for the
register layouts, but I think that's ok as these are generally unchanging.

Commit 09bf82fd adds basic powerpc support, but it's limited to only 6
registers (including IP) due to a limitation noted in Dyninst's
