3543 * Some of these comments may well be out-of-date.

3545 * splitting/merging in the few cases when it's required: a back jump to an IL
3546 * address that was not already seen as bblock starting point).
3547 * Code is validated as we go (full verification is still better left to metadata/verify.c).
3548 * Complex operations are decomposed in simpler ones right away. We need to let the
3549 * arch-specific code peek and poke inside this process somehow (except when the
3550 * optimizations can take advantage of the full semantic info of coarse opcodes).
3551 * All the opcodes of the form opcode.s are 'normalized' to opcode.
3552 * MonoInst->opcode initially is the IL opcode or some simplification of that
3553 * (OP_LOAD, OP_STORE). The arch-specific code may rearrange it to an arch-specific
3554 * opcode with value bigger than OP_LAST.
3555 * At this point the IR can be handed over to an interpreter, a dumb code generator
3556 * or to the optimizing code generator that will translate it to SSA form.
3558 * Profiling directed optimizations.
3559 * We may compile by default with few or no optimizations and instrument the code
3560 * or the user may indicate what methods to optimize the most either in a config file
3561 * or through repeated runs where the compiler applies offline the optimizations to
3562 * each method and then decides if it was worth it.
