* ARM: Make arch_specific_insn a define for new arch_probes_insn structureDavid A. Long2014-03-181-2/+2
| | | | | | | | | | | | | | Because the common underlying code for ARM kprobes and uprobes needs to share a common architecrure-specific context structure, and because the generic kprobes include file insists on defining this to a dummy structure when kprobes is not configured, a new common structure is required which can exist when uprobes is configured without kprobes. In this case kprobes will define a dummy structure, but without the define aliasing the two structure tags it will not affect uprobes and the shared probes code. Signed-off-by: David A.

* ARM: Add an emulate flag to the kprobes/uprobes instruction decode functionsDavid A. Long2014-03-181-2/+2
| | | | | | | | Add an emulate flag into the instruction interpreter, primarily for uprobes support. Signed-off-by: David A. Long <dave.long@linaro.org> Acked-by: Jon Medhurst <tixy@linaro.org>
* ARM: Change the remaining shared kprobes/uprobes symbols to something genericDavid A. Long2014-03-181-0/+10
| | | | | | | | Any more ARM kprobes/uprobes symbols which have "kprobe" in the name must be changed to the more generic "probes" or other non-kprobes specific symbol. Signed-off-by: David A. Long <dave.long@linaro.org> Acked-by: Jon Medhurst <tixy@linaro.org>
* ARM: use a function table for determining instruction interpreter actionDavid A. Long2014-03-181-49/+55
| | | | | | | | | | | Make the instruction interpreter call back to semantic action functions through a function pointer array provided by the invoker. The interpreter decodes the instructions into groups and uses the group number to index into the supplied array. kprobes and uprobes code will each supply their own array of functions.

* ARM: move generic thumb instruction parsing code to new files for use by ↵David A. Long2014-03-181-0/+81
other feature Move the thumb version of the kprobes instruction parsing code into more generic files from where it can be used by uprobes and possibly other subsystems. The symbol names will be made more generic in a subsequent part of this patchset. Signed-off-by: David A. Long <dave.long@linaro.org> Acked-by: Jon Medhurst <tixy@linaro.org>
