When we emit + // a load or store of a bit-field, we'll load/store the entire containing + // access unit. As mentioned, the standard requires that these loads and + // stores must not interfere with accesses to other memory locations, and it + // defines the bit-field's memory location as the current run of + // non-zero-width bit-fields. So an access unit must never overlap with + // non-bit-field storage or cross a zero-width bit-field. Otherwise, we're + // free to draw the lines as we see fit. + + // Drawing these lines well can be complicated. LLVM generally can't modify a + // program to access memory that it didn't before, so using very narrow access + // units can prevent the compiler from using optimal access patterns. For + // example, suppose a run of bit-fields occupies four bytes in a struct. If we + // split that into four 1-byte access units, then a sequence of assignments + // that doesn't touch all four bytes may have to be emitted with multiple + // 8-bit stores instead of a single 32-bit store. On the other hand, if we use + // very wide access units, we may find ourselves emitting accesses to + // bit-fields we didn't really need to touch, just because LLVM was unable to + // clean up after us. + + // It is desirable to have access units be aligned powers of 2 no larger than + // a register. (On non-strict alignment ISAs, the alignment requirement can be + // dropped.) A three byte access unit will be accessed using 2-byte and 1-byte + // accesses and bit manipulation. If no bitfield straddles across the two + // separate accesses, it is better to have separate 2-byte and 1-byte access + // units, as then LLVM will not generate unnecessary memory accesses, or bit + // manipulation. Similarly, on a strict-alignment architecture, it is better + // to keep access-units naturally aligned, to avoid similar bit + // manipulation synthesizing larger unaligned accesses. + + // Bitfields that share parts of a single byte are, of necessity, placed in + // the same access unit. That unit will encompass a consecutive run where + // adjacent bitfields share parts of a byte. (The first bitfield of such an + // access unit will start at the beginning of a byte.) + + // We then try and accumulate adjacent access units when the combined unit is + // naturally sized, no larger than a register, and (on a strict alignment + // ISA), naturally aligned. Note that this requires lookahead to one or more + // subsequent access units. For instance, consider a 2-byte access-unit + // followed by 2 1-byte units.
