x86: Create header for VEC classes in x86 strings library
|
|
|
|
This patch does not touch any existing code and is only meant to be a
|
|
tool for future patches so that simple source files can more easily be
|
|
maintained to target multiple VEC classes.
|
|
|
|
There is no difference in the objdump of libc.so before and after this
|
|
patch.
