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. |
