[Bug runtime/10601] user-space deref/registers in loc2c

[mjw at redhat dot com]

------- Additional Comments From mjw at redhat dot com  2009-09-04 07:05 -------
This is the root cause of bug #10318 "Bad address reading arg from mark probe"
which also contains some discussions about the implementation of this in loc2c.
The register mapping disparity also seems to be the root cause of some of the
exelib.exp mark.tcl tests failing (currently disabled) on 32-on-64 bit systems,
bug #10289 "stap probes user space markers don't work with 32-on-64
executables". On i386 some sdt_misc.exp sdt_types tests are failing, which most
likely can also be attributed to the register fetch mismatch in user space.

It might be good to make comment #1 into its own bug.
