Log:
elf-core: Convert remaining register context to use register set maps
In https://reviews.llvm.org/D39681, we started using a map instead
passing a long list of register sets to the ppc64le register context.
However, existing register contexts were still using the old method.
This converts the remaining register contexts to use this approach.
While doing that, I've had to modify the approach a bit:
- the general purpose register set is still kept as a separate field,
because this one is always present, and it's parsing is somewhat
different than that of other register sets.
- since the same register sets have different IDs on different operating
systems, but we use the same register context class to represent
different register sets, I've needed to add a layer of indirection to
translate os-specific constants (e.g. NETBSD::NT_AMD64_FPREGS) into more
generic terms (e.g. floating point register set).
While slightly more complicated, this setup allows for better separation
of concerns. The parsing code in ProcessElfCore can focus on parsing
OS-specific core file notes, and can completely ignore
architecture-specific register sets (by just storing any unrecognised
notes in a map). These notes will then be passed on to the
architecture-specific register context, which can just deal with
architecture specifics, because the OS-specific note types are hidden in
a register set description map.
This way, adding an register set, which is already supported on other
OSes, to a new OS, should in most cases be as simple as adding a new
entry into the register set description map.
