7291 * optimizations can take advantage of the full semantic info of coarse opcodes).
7292 * All the opcodes of the form opcode.s are 'normalized' to opcode.
7293 * MonoInst->opcode initially is the IL opcode or some simplification of that
7294 * (OP_LOAD, OP_STORE). The arch-specific code may rearrange it to an arch-specific
7295 * opcode with value bigger than OP_LAST.
7296 * At this point the IR can be handed over to an interpreter, a dumb code generator
7297 * or to the optimizing code generator that will translate it to SSA form.
7299 * Profiling directed optimizations.
7300 * We may compile by default with few or no optimizations and instrument the code
7301 * or the user may indicate what methods to optimize the most either in a config file
7302 * or through repeated runs where the compiler applies offline the optimizations to
7303 * each method and then decides if it was worth it.

15153 * - unify iregs/fregs
15154 * -> partly done, the missing parts are:
15155 * - a more complete unification would involve unifying the hregs as well, so
15156 * code wouldn't need if (fp) all over the place. but that would mean the hregs
15157 * would no longer map to the machine hregs, so the code generators would need to
15158 * be modified. Also, on ia64 for example, niregs + nfregs > 256 -> bitmasks
15159 * wouldn't work any more. Duplicating the code in mono_local_regalloc () into
15160 * fp/non-fp branches speeds it up by about 15%.
15161 * - use sext/zext opcodes instead of shifts
15163 * - get rid of TEMPLOADs if possible and use vregs instead
15164 * - clean up usage of OP_P/OP_ opcodes
15165 * - cleanup usage of DUMMY_USE
15166 * - cleanup the setting of ins->type for MonoInst's which are pushed on the
15168 * - set the stack type and allocate a dreg in the EMIT_NEW macros
15169 * - get rid of all the <foo>2 stuff when the new JIT is ready.
15170 * - make sure handle_stack_args () is called before the branch is emitted
15171 * - when the new IR is done, get rid of all unused stuff
15172 * - COMPARE/BEQ as separate instructions or unify them ?
15173 * - keeping them separate allows specialized compare instructions like
15174 * compare_imm, compare_membase
15175 * - most back ends unify fp compare+branch, fp compare+ceq
15176 * - integrate mono_save_args into inline_method
15177 * - get rid of the empty bblocks created by MONO_EMIT_NEW_BRACH_BLOCK2
15178 * - handle long shift opts on 32 bit platforms somehow: they require
15179 * 3 sregs (2 for arg1 and 1 for arg2)
15180 * - make byref a 'normal' type.
15181 * - use vregs for bb->out_stacks if possible, handle_global_vreg will make them a
15182 * variable if needed.
15183 * - do not start a new IL level bblock when cfg->cbb is changed by a function call
15184 * like inline_method.
15185 * - remove inlining restrictions
15186 * - fix LNEG and enable cfold of INEG
15187 * - generalize x86 optimizations like ldelema as a peephole optimization
15188 * - add store_mem_imm for amd64
15189 * - optimize the loading of the interruption flag in the managed->native wrappers
15190 * - avoid special handling of OP_NOP in passes
15191 * - move code inserting instructions into one function/macro.
15192 * - try a coalescing phase after liveness analysis
15193 * - add float -> vreg conversion + local optimizations on !x86
15194 * - figure out how to handle decomposed branches during optimizations, ie.
15195 * compare+branch, op_jump_table+op_br etc.
15196 * - promote RuntimeXHandles to vregs
15197 * - vtype cleanups:
15198 * - add a NEW_VARLOADA_VREG macro
15199 * - the vtype optimizations are blocked by the LDADDR opcodes generated for
15200 * accessing vtype fields.
15201 * - get rid of I8CONST on 64 bit platforms
15202 * - dealing with the increase in code size due to branches created during opcode
15204 * - use extended basic blocks
15205 * - all parts of the JIT
15206 * - handle_global_vregs () && local regalloc
15207 * - avoid introducing global vregs during decomposition, like 'vtable' in isinst
15208 * - sources of increase in code size:
15211 * - isinst and castclass
15212 * - lvregs not allocated to global registers even if used multiple times
15213 * - call cctors outside the JIT, to make -v output more readable and JIT timings more
15215 * - check for fp stack leakage in other opcodes too. (-> 'exceptions' optimization)
15216 * - add all micro optimizations from the old JIT
15217 * - put tree optimizations into the deadce pass
15218 * - decompose op_start_handler/op_endfilter/op_endfinally earlier using an arch
15219 * specific function.
15220 * - unify the float comparison opcodes with the other comparison opcodes, i.e.
15221 * fcompare + branchCC.
15222 * - create a helper function for allocating a stack slot, taking into account
15223 * MONO_CFG_HAS_SPILLUP.
15225 * - merge the ia64 switch changes.
15226 * - optimize mono_regstate2_alloc_int/float.
15227 * - fix the pessimistic handling of variables accessed in exception handler blocks.
15228 * - need to write a tree optimization pass, but the creation of trees is difficult, i.e.
15229 * parts of the tree could be separated by other instructions, killing the tree
15230 * arguments, or stores killing loads etc. Also, should we fold loads into other
15231 * instructions if the result of the load is used multiple times ?
15232 * - make the REM_IMM optimization in mini-x86.c arch-independent.
15233 * - LAST MERGE: 108395.
15234 * - when returning vtypes in registers, generate IR and append it to the end of the
15235 * last bb instead of doing it in the epilog.
15236 * - change the store opcodes so they use sreg1 instead of dreg to store the base register.
15244 - When to decompose opcodes:
15245 - earlier: this makes some optimizations hard to implement, since the low level IR
15246 no longer contains the neccessary information. But it is easier to do.
15247 - later: harder to implement, enables more optimizations.
15248 - Branches inside bblocks:
15249 - created when decomposing complex opcodes.
15250 - branches to another bblock: harmless, but not tracked by the branch
15251 optimizations, so need to branch to a label at the start of the bblock.
15252 - branches to inside the same bblock: very problematic, trips up the local
15253 reg allocator. Can be fixed by spitting the current bblock, but that is a
15254 complex operation, since some local vregs can become global vregs etc.
15255 - Local/global vregs:
15256 - local vregs: temporary vregs used inside one bblock. Assigned to hregs by the
15257 local register allocator.
15258 - global vregs: used in more than one bblock. Have an associated MonoMethodVar
15259 structure, created by mono_create_var (). Assigned to hregs or the stack by
15260 the global register allocator.
15261 - When to do optimizations like alu->alu_imm:
15262 - earlier -> saves work later on since the IR will be smaller/simpler
15263 - later -> can work on more instructions
15264 - Handling of valuetypes:
15265 - When a vtype is pushed on the stack, a new temporary is created, an
15266 instruction computing its address (LDADDR) is emitted and pushed on
15267 the stack. Need to optimize cases when the vtype is used immediately as in
15268 argument passing, stloc etc.
15269 - Instead of the to_end stuff in the old JIT, simply call the function handling
15270 the values on the stack before emitting the last instruction of the bb.
