6289 * optimizations can take advantage of the full semantic info of coarse opcodes).
6290 * All the opcodes of the form opcode.s are 'normalized' to opcode.
6291 * MonoInst->opcode initially is the IL opcode or some simplification of that
6292 * (OP_LOAD, OP_STORE). The arch-specific code may rearrange it to an arch-specific
6293 * opcode with value bigger than OP_LAST.
6294 * At this point the IR can be handed over to an interpreter, a dumb code generator
6295 * or to the optimizing code generator that will translate it to SSA form.
6297 * Profiling directed optimizations.
6298 * We may compile by default with few or no optimizations and instrument the code
6299 * or the user may indicate what methods to optimize the most either in a config file
6300 * or through repeated runs where the compiler applies offline the optimizations to
6301 * each method and then decides if it was worth it.

14090 * - use 'iadd' instead of 'int_add'
14091 * - handling ovf opcodes: decompose in method_to_ir.
14092 * - unify iregs/fregs
14093 * -> partly done, the missing parts are:
14094 * - a more complete unification would involve unifying the hregs as well, so
14095 * code wouldn't need if (fp) all over the place. but that would mean the hregs
14096 * would no longer map to the machine hregs, so the code generators would need to
14097 * be modified. Also, on ia64 for example, niregs + nfregs > 256 -> bitmasks
14098 * wouldn't work any more. Duplicating the code in mono_local_regalloc () into
14099 * fp/non-fp branches speeds it up by about 15%.
14100 * - use sext/zext opcodes instead of shifts
14102 * - get rid of TEMPLOADs if possible and use vregs instead
14103 * - clean up usage of OP_P/OP_ opcodes
14104 * - cleanup usage of DUMMY_USE
14105 * - cleanup the setting of ins->type for MonoInst's which are pushed on the
14107 * - set the stack type and allocate a dreg in the EMIT_NEW macros
14108 * - get rid of all the <foo>2 stuff when the new JIT is ready.
14109 * - make sure handle_stack_args () is called before the branch is emitted
14110 * - when the new IR is done, get rid of all unused stuff
14111 * - COMPARE/BEQ as separate instructions or unify them ?
14112 * - keeping them separate allows specialized compare instructions like
14113 * compare_imm, compare_membase
14114 * - most back ends unify fp compare+branch, fp compare+ceq
14115 * - integrate mono_save_args into inline_method
14116 * - get rid of the empty bblocks created by MONO_EMIT_NEW_BRACH_BLOCK2
14117 * - handle long shift opts on 32 bit platforms somehow: they require
14118 * 3 sregs (2 for arg1 and 1 for arg2)
14119 * - make byref a 'normal' type.
14120 * - use vregs for bb->out_stacks if possible, handle_global_vreg will make them a
14121 * variable if needed.
14122 * - do not start a new IL level bblock when cfg->cbb is changed by a function call
14123 * like inline_method.
14124 * - remove inlining restrictions
14125 * - fix LNEG and enable cfold of INEG
14126 * - generalize x86 optimizations like ldelema as a peephole optimization
14127 * - add store_mem_imm for amd64
14128 * - optimize the loading of the interruption flag in the managed->native wrappers
14129 * - avoid special handling of OP_NOP in passes
14130 * - move code inserting instructions into one function/macro.
14131 * - try a coalescing phase after liveness analysis
14132 * - add float -> vreg conversion + local optimizations on !x86
14133 * - figure out how to handle decomposed branches during optimizations, ie.
14134 * compare+branch, op_jump_table+op_br etc.
14135 * - promote RuntimeXHandles to vregs
14136 * - vtype cleanups:
14137 * - add a NEW_VARLOADA_VREG macro
14138 * - the vtype optimizations are blocked by the LDADDR opcodes generated for
14139 * accessing vtype fields.
14140 * - get rid of I8CONST on 64 bit platforms
14141 * - dealing with the increase in code size due to branches created during opcode
14143 * - use extended basic blocks
14144 * - all parts of the JIT
14145 * - handle_global_vregs () && local regalloc
14146 * - avoid introducing global vregs during decomposition, like 'vtable' in isinst
14147 * - sources of increase in code size:
14150 * - isinst and castclass
14151 * - lvregs not allocated to global registers even if used multiple times
14152 * - call cctors outside the JIT, to make -v output more readable and JIT timings more
14154 * - check for fp stack leakage in other opcodes too. (-> 'exceptions' optimization)
14155 * - add all micro optimizations from the old JIT
14156 * - put tree optimizations into the deadce pass
14157 * - decompose op_start_handler/op_endfilter/op_endfinally earlier using an arch
14158 * specific function.
14159 * - unify the float comparison opcodes with the other comparison opcodes, i.e.
14160 * fcompare + branchCC.
14161 * - create a helper function for allocating a stack slot, taking into account
14162 * MONO_CFG_HAS_SPILLUP.
14164 * - optimize mono_regstate2_alloc_int/float.
14165 * - fix the pessimistic handling of variables accessed in exception handler blocks.
14166 * - need to write a tree optimization pass, but the creation of trees is difficult, i.e.
14167 * parts of the tree could be separated by other instructions, killing the tree
14168 * arguments, or stores killing loads etc. Also, should we fold loads into other
14169 * instructions if the result of the load is used multiple times ?
14170 * - make the REM_IMM optimization in mini-x86.c arch-independent.
14171 * - LAST MERGE: 108395.
14172 * - when returning vtypes in registers, generate IR and append it to the end of the
14173 * last bb instead of doing it in the epilog.
14174 * - change the store opcodes so they use sreg1 instead of dreg to store the base register.
14182 - When to decompose opcodes:
14183 - earlier: this makes some optimizations hard to implement, since the low level IR
14184 no longer contains the neccessary information. But it is easier to do.
14185 - later: harder to implement, enables more optimizations.
14186 - Branches inside bblocks:
14187 - created when decomposing complex opcodes.
14188 - branches to another bblock: harmless, but not tracked by the branch
14189 optimizations, so need to branch to a label at the start of the bblock.
14190 - branches to inside the same bblock: very problematic, trips up the local
14191 reg allocator. Can be fixed by spitting the current bblock, but that is a
14192 complex operation, since some local vregs can become global vregs etc.
14193 - Local/global vregs:
14194 - local vregs: temporary vregs used inside one bblock. Assigned to hregs by the
14195 local register allocator.
14196 - global vregs: used in more than one bblock. Have an associated MonoMethodVar
14197 structure, created by mono_create_var (). Assigned to hregs or the stack by
14198 the global register allocator.
14199 - When to do optimizations like alu->alu_imm:
14200 - earlier -> saves work later on since the IR will be smaller/simpler
14201 - later -> can work on more instructions
14202 - Handling of valuetypes:
14203 - When a vtype is pushed on the stack, a new temporary is created, an
14204 instruction computing its address (LDADDR) is emitted and pushed on
14205 the stack. Need to optimize cases when the vtype is used immediately as in
14206 argument passing, stloc etc.
14207 - Instead of the to_end stuff in the old JIT, simply call the function handling
14208 the values on the stack before emitting the last instruction of the bb.
