Sigh,

This patch changes the regcache so that, when REGISTER_BYTE or REGISTER_RAW_SIZE are present, the old style legacy regcache layout is used.

This will stop those regcache assertion failures. Fixing the problem (especially for MIPS) will just get too messy for the branch :-(

My thought is to commit this to 6.0 branch, while on the mainline delete REGISTER_BYTE and REGISTER_RAW_SIZE and just wear the consequences ...
comments and/or suggestions?

Makes sense to me.  You've been making steady progress on this problem,
and it looks like it's just finally time to kill REGISTER_BYTE.

If I delete them, I think the MIPS nat code will break. There is an assumption that, at least on IRIX, when a 32 bit ABI on a 64 bit ISA, all the registers are 32 bit left aligned within the 64 bit field (I think they should be sign extended).

:-(
