Hi,
As PR116148#c7 shows, fam-in-union-alone-in-struct-2.c still
fails on hppa which is a BE environment, but by checking more
(also confirmed by John in PR116148#c12), it's due to that
signedness of plain char on hppa is signed therefore the value
of with_fam_3_v.a[7] "8f" get sign extended as "ffffff8f" then
the verification will fail. This patch is to change plain char
with unsigned char to avoid that.
Tested well powerpc64-linux-gnu (BE) and powerpc64le-linux-gnu
(LE), also confirmed to work on hppa by John.
Is it ok for trunk?
BR,
Kewen
