3466 * Some of these comments may well be out-of-date.
3467 * Design decisions: we do a single pass over the IL code (and we do bblock
3468 * splitting/merging in the few cases when it's required: a back jump to an IL
3469 * address that was not already seen as bblock starting point).
3470 * Code is validated as we go (full verification is still better left to metadata/verify.c).
3471 * Complex operations are decomposed in simpler ones right away. We need to let the
3472 * arch-specific code peek and poke inside this process somehow (except when the
3473 * optimizations can take advantage of the full semantic info of coarse opcodes).
3474 * All the opcodes of the form opcode.s are 'normalized' to opcode.
3475 * MonoInst->opcode initially is the IL opcode or some simplification of that
3476 * (OP_LOAD, OP_STORE). The arch-specific code may rearrange it to an arch-specific
3477 * opcode with value bigger than OP_LAST.
3478 * At this point the IR can be handed over to an interpreter, a dumb code generator
3479 * or to the optimizing code generator that will translate it to SSA form.
3481 * Profiling directed optimizations.
3482 * We may compile by default with few or no optimizations and instrument the code
3483 * or the user may indicate what methods to optimize the most either in a config file
3484 * or through repeated runs where the compiler applies offline the optimizations to
3485 * each method and then decides if it was worth it.
3488 * * consider using an array instead of an hash table (bb_hash)
