Hello.
As reported here:
https://github.com/HSAFoundation/gccbrig/issues/6#issuecomment-197986345
current HSA back-end produces wrong alignment load/stores, for instance in
following example:
prog function &foo(align(4) arg_u8 %res[12])(align(4) arg_u8 %c[12]) <--- 'c'
has alignment just 4
{
align(4) private_u8 %__private_0[12];
align(4) private_u8 %__hsa_anonymous_2357[12];
ld_arg_align(8)_u64 $d0, [%c]; <---- alignment == 8
....
