[PowerPC] Don't zero-initialize vector register buffers
|
|
|
7cb06c |
|
|
|
7cb06c |
Now that linux-tdep.c already zero-initializes the buffer used for
|
|
|
7cb06c |
generating core file notes, there is no need to do this in the linux
|
|
|
7cb06c |
collect functions for the vector regset. The memsets in gdbserver were
|
|
|
7cb06c |
not useful to begin with.
