Otherwise their alignment is dependent on the size of the section. If the size is large than 16, the alignment will be 16. 16 is a bad choice for both .llvmbc and .llvmcmd because the padding between two contributions from input sections is of a variable size. A bitstream is actually guaranteed to be 4-byte aligned, but consumers don't need this property.
