2487 * address that was not already seen as bblock starting point).
2488 * Code is validated as we go (full verification is still better left to metadata/verify.c).
2489 * Complex operations are decomposed in simpler ones right away. We need to let the
2490 * arch-specific code peek and poke inside this process somehow (except when the
2491 * optimizations can take advantage of the full semantic info of coarse opcodes).
2492 * All the opcodes of the form opcode.s are 'normalized' to opcode.
2493 * MonoInst->opcode initially is the IL opcode or some simplification of that
2494 * (OP_LOAD, OP_STORE). The arch-specific code may rearrange it to an arch-specific
2495 * opcode with value bigger than OP_LAST.
2496 * At this point the IR can be handed over to an interpreter, a dumb code generator
2497 * or to the optimizing code generator that will translate it to SSA form.
2499 * Profiling directed optimizations.
2500 * We may compile by default with few or no optimizations and instrument the code
2501 * or the user may indicate what methods to optimize the most either in a config file
2502 * or through repeated runs where the compiler applies offline the optimizations to
2503 * each method and then decides if it was worth it.
2506 * * consider using an array instead of an hash table (bb_hash)
