[PATCH v2 0/3] Read pseudo registers from frame instead of regcache

[Simon Marchi]

Hi,

This is a follow-up of

  https://sourceware.org/ml/gdb-patches/2018-05/msg00705.html

The main changes are:

- Re-use the regcache interface to read registers from frames
- Deal with debug info that contains unwind info for pseudo registers

Simon Marchi (3):
  Extract register_reader and register_readwriter interfaces from
    regcache
  Read pseudo registers from frame instead of regcache
  Add tests for unwinding of pseudo registers
