The main problem is it isn't streamable. Everything is split into
multiple sections in the binary. For example, instructions have
their operands placed in a different section and the instruction
encoding includes the offset into the other section. libHSAIL needs
to construct the full output for the module in memory and then emit
code at the end, which is not how MC expects binary formats to work.
This particular problem we've thought might be fixable with lots of
custom fixups.<br>
There are also issues with debug info. One of the problems is that
the text format currently doesn't have a way of representing DWARF,
and BRIG has its own special handling of DWARF in a separate section
as well. Binary formats and MC aren't areas I'm particularly
familiar with.<br>
