S390: Support new vector register sections
|
||
|
|
|
||
|
|
The IBM z13 has new 128-bit wide vector registers v0-v31, where v0-v15
|
||
|
|
include the existing 64-bit wide floating point registers. The Linux
|
||
|
|
kernel presents the vector registers as two additional register sets,
|
||
|
|
one for the right halves of v0-v15 and another one for the full
|
||
|
|
registers v16-v31. Thus a new core file may contain two new register
|
||
|
|
note sections, and this patch adds support to binutils for them.
