make powerpc64 vrregset_t logical layout match expected API
|
|
|
|
between v2 and v3 of the powerpc64 port patch, the change was made
|
|
from a 32x4 array of 32-bit unsigned ints for vrregs[] to a 32-element
|
|
array of __int128. this mismatches the API applications working with
|
|
mcontext_t expect from glibc, and seems to have been motivated by a
|
|
misinterpretation of a comment on how aarch64 did things as a
|
|
suggestion to do the same on powerpc64.
