2021-03-09ssa: avoid SSA conversion of packed bitfieldsLuc Van Oostenryck1-1/+0
Packed bitfields are incompatible with the SSA conversion which works on the assumption that memory operations are done on the whole symbol. So, directly exclude packed bitfields from the SSA conversion. Signed-off-by: Luc Van Oostenryck <luc.vanoostenryck@gmail.com>
2021-03-09ssa: add some testcases for mismatched memopsLuc Van Oostenryck1-0/+36
The SSA conversion is incorrect when the size or offset of the memory operations doesn't match. It shouldn't be done at all. So, add a few testcases for this. Signed-off-by: Luc Van Oostenryck <luc.vanoostenryck@gmail.com>
