Hi,
The uninitialized variable a in pr60510.f can cause some
random failures as exposed in PR111427, see the details
there. This patch is to make it initialized accordingly.
As verified, it can fix the reported -m32 failures on
P7 and P8 BE. It's also tested well on powerpc64-linux-gnu
P9 and powerpc64le-linux-gnu P9 and P10.
Is it ok for trunk?
BR,
Kewen
