------- Comment #78 from jasmin at revisionfx dot com 2010-08-09 01:56 -------
I am not exactly sure how to report a bug here - but it seems highly related to
this thread (I am pie...@revisionfx.com, since I am not sure if I am
auto-subscribed to this thread, and so will get email back about this)
It appears (whatever the version) that this construct in 32b linux (below) does
not work after -shared (ld...) - does not work means is not aligned anymore to
16 bytes/128 bits boundary. If I compile a library with such code, and link it
as in an executable, it seems to work but if I do it as shared object the
alignment is not guaranteed anymore. Anyone has an idea about what to do, if
this will be addressed... or GNU just assumes 32b will go away? Or the problem
is different. All this works fine with Mac OSX gcc -m32 compile by the way.
Also, if I compile with Intel CC does that fix the problem for an host that is
Intel CC compiled? (As in is it possible that mixed compiler context - host
versus dynamic library further cause complications).
#define MAX_CONV_KERNEL_SIZE 4096
class ConvKernel4f
{
public:
ConvKernel4f ( );
~ConvKernel4f( );
DATA_ALIGN(float4 mFilterPtr[MAX_CONV_KERNEL_SIZE]);
};
