Subject: [PATCH] powerpc64: fix handling of homogeneous float128 structs
|
||
|
|
|
||
|
|
If there is a homogeneous struct with float128 members, they should be
|
||
|
|
copied to vector register save area. The current code incorrectly copies
|
||
|
|
only the value of the first member, not increasing the pointer with each
|
||
|
|
iteration. Fix this.
