2156 * address that was not already seen as bblock starting point).
2157 * Code is validated as we go (full verification is still better left to metadata/verify.c).
2158 * Complex operations are decomposed in simpler ones right away. We need to let the
2159 * arch-specific code peek and poke inside this process somehow (except when the
2160 * optimizations can take advantage of the full semantic info of coarse opcodes).
2161 * All the opcodes of the form opcode.s are 'normalized' to opcode.
2162 * MonoInst->opcode initially is the IL opcode or some simplification of that
2163 * (OP_LOAD, OP_STORE). The arch-specific code may rearrange it to an arch-specific
2164 * opcode with value bigger than OP_LAST.
2165 * At this point the IR can be handed over to an interpreter, a dumb code generator
2166 * or to the optimizing code generator that will translate it to SSA form.
2168 * Profiling directed optimizations.
2169 * We may compile by default with few or no optimizations and instrument the code
2170 * or the user may indicate what methods to optimize the most either in a config file
2171 * or through repeated runs where the compiler applies offline the optimizations to
2172 * each method and then decides if it was worth it.
