Subject: [PATCH 17/18] ppc64le: Fix calling convention of external functions
|
|
|
f9602d |
with > 8 parameters (RHBZ#1225995).
|

For external (ie. C) functions with more than 8 parameters, we must
|
|
|
f9602d |
pass the first 8 parameters in registers and then all the remaining
|
|
|
f9602d |
parameters on the stack.
|
|

Unfortunately the original backend copied the stack offset from ppc64,
|
|
|
f9602d |
where it works, but the offset was wrong for ppc64le.
|
|
|
f9602d |
|
|
|
f9602d |
By experimentation I found the correct offset.
