2470 * splitting/merging in the few cases when it's required: a back jump to an IL
2471 * address that was not already seen as bblock starting point).
2472 * Code is validated as we go (full verification is still better left to metadata/verify.c).
2473 * Complex operations are decomposed in simpler ones right away. We need to let the
2474 * arch-specific code peek and poke inside this process somehow (except when the
2475 * optimizations can take advantage of the full semantic info of coarse opcodes).
2476 * All the opcodes of the form opcode.s are 'normalized' to opcode.
2477 * MonoInst->opcode initially is the IL opcode or some simplification of that
2478 * (OP_LOAD, OP_STORE). The arch-specific code may rearrange it to an arch-specific
2479 * opcode with value bigger than OP_LAST.
2480 * At this point the IR can be handed over to an interpreter, a dumb code generator
2481 * or to the optimizing code generator that will translate it to SSA form.
2483 * Profiling directed optimizations.
2484 * We may compile by default with few or no optimizations and instrument the code
2485 * or the user may indicate what methods to optimize the most either in a config file
2486 * or through repeated runs where the compiler applies offline the optimizations to
2487 * each method and then decides if it was worth it.
2490 * * consider using an array instead of an hash table (bb_hash)
