4406  * Some of these comments may well be out-of-date.

4408  * splitting/merging in the few cases when it's required: a back jump to an IL
4409  * address that was not already seen as bblock starting point).
4410  * Code is validated as we go (full verification is still better left to metadata/verify.c).
4411  * Complex operations are decomposed in simpler ones right away. We need to let the
4412  * arch-specific code peek and poke inside this process somehow (except when the
4413  * optimizations can take advantage of the full semantic info of coarse opcodes).
4414  * All the opcodes of the form opcode.s are 'normalized' to opcode.
4415  * MonoInst->opcode initially is the IL opcode or some simplification of that
4416  * (OP_LOAD, OP_STORE). The arch-specific code may rearrange it to an arch-specific
4417  * opcode with value bigger than OP_LAST.
4418  * At this point the IR can be handed over to an interpreter, a dumb code generator
4419  * or to the optimizing code generator that will translate it to SSA form.
4420  *
4421  * Profiling directed optimizations.
4422  * We may compile by default with few or no optimizations and instrument the code
4423  * or the user may indicate what methods to optimize the most either in a config file
4424  * or through repeated runs where the compiler applies offline the optimizations to
4425  * each method and then decides if it was worth it.
