[PATCH v3 00/13] Regset rework preparations part 2

[Andreas Arnez]

Version 2 is here:

  https://sourceware.org/ml/gdb-patches/2014-06/msg00881.html

Changes in version 3:

* Add new (optional) field 'size' to struct regcache_map_entry.  Exploit
  this in most regmaps.

* regcache_supply/collect_regset: Support the new 'size' field.  Also
  treat the case of a single register more efficiently.  In order to
  reduce code duplication, combine the supply- and collect-logic in one
  local worker function.

* S390: Correct s390_regmap_last_break.

* HPPA: Set slot size for each FP register to 4, to replicate original
  behavior.  Add "FIXME" comment, since this doesn't seem to match the
  register types in 64-bit mode.

* SCORE: Avoid negative offsets in regmap and add explicit logic for
  supplying EPC from same slot as PC.

* TILEGX: Use 8-byte slots for all registers, including the PC.

* M68K: Set slot size for each FP register to 12, even on ColdFire,
  where FP regs are just 8 bytes long and thus leave gaps.  Also
  increase M68K_LINUX_GREGS_SIZE to (20 * 4).

* Correct IA64_LINUX_GREGS_SIZE and IA64_LINUX_FPREGS_SIZE.

Andreas Arnez (13):
  Rename 'descr' field in regset structure to 'regmap'.
  regcache: Add functions suitable for regset_supply/collect.
  S390: Migrate to regcache_supply/collect_regset.
  AARCH64 Linux: Fill 'collect_regset' in regset structures.
  ALPHA Linux: Fill 'collect_regset' in regset structures.
  FRV Linux: Fill 'collect_regset' in regset structures.
  HPPA Linux: Fill 'collect_regset' in regset structures.
  M32R Linux: Fill 'collect_regset' in regset structure.
  NIOS2 Linux: Fill 'collect_regset' in regset structure.
  SCORE: Fill 'collect_regset' in regset structure.
  TILEGX Linux: Fill 'collect_regset' in regset structure.
  M68K Linux: Define regset structures.
  IA64 Linux: Define regset structures.
