851</p>
852
853<h2 id="LuaJIT-1.1.0">LuaJIT 1.1.0 &mdash; 2006-03-13</h2>
854<ul>
855<li>Merged with Lua 5.1 (final).</li>
856
857<li>New JIT call frame setup:
858<ul>
859<li>The C stack is kept 16 byte aligned (faster).
860Mandatory for Mac OS X on Intel, too.</li>
861<li>Faster calling conventions for internal C helper functions.</li>
862<li>Better instruction scheduling for function prologue, OP_CALL and
863OP_RETURN.</li>
864</ul></li>
865
866<li>Miscellaneous optimizations:
867<ul>
868<li>Faster loads of FP constants. Remove narrow-to-wide store-to-load
869forwarding stalls.</li>
870<li>Use (scalar) SSE2 ops (if the CPU supports it) to speed up slot moves
871and FP to integer conversions.</li>
872<li>Optimized the two-argument form of <tt>OP_CONCAT</tt> (<tt>a..b</tt>).</li>
873<li>Inlined <tt>OP_MOD</tt> (<tt>a%b</tt>).
874With better accuracy than the C variant, too.</li>
875<li>Inlined <tt>OP_POW</tt> (<tt>a^b</tt>). Unroll <tt>x^k</tt> or
876use <tt>k^x = 2^(log2(k)*x)</tt> or call <tt>pow()</tt>.</li>
877</ul></li>
878
879<li>Changes in the optimizer:
880<ul>
881<li>Improved hinting for table keys derived from table values
882(<tt>t1[t2[x]]</tt>).</li>
883<li>Lookup hinting now works with arbitrary object types and
884supports index chains, too.</li>
885<li>Generate type hints for arithmetic and comparison operators,
886OP_LEN, OP_CONCAT and OP_FORPREP.</li>
887<li>Remove several hint definitions in favour of a generic COMBINE hint.</li>
888<li>Complete rewrite of <tt>jit.opt_inline</tt> module
889(ex <tt>jit.opt_lib</tt>).</li>
890</ul></li>
891
892<li>Use adaptive deoptimization:
893<ul>
894<li>If runtime verification of a contract fails, the affected
895instruction is recompiled and patched on-the-fly.
896Regular programs will trigger deoptimization only occasionally.</li>
897<li>This avoids generating code for uncommon fallback cases
898most of the time. Generated code is up to 30% smaller compared to
899LuaJIT&nbsp;1.0.3.</li>
900<li>Deoptimization is used for many opcodes and contracts:
901<ul>
902<li>OP_CALL, OP_TAILCALL: type mismatch for callable.</li>
903<li>Inlined calls: closure mismatch, parameter number and type mismatches.</li>
904<li>OP_GETTABLE, OP_SETTABLE: table or key type and range mismatches.</li>
905<li>All arithmetic and comparison operators, OP_LEN, OP_CONCAT,
906OP_FORPREP: operand type and range mismatches.</li>
907</ul></li>
908<li>Complete redesign of the debug and traceback info
909(bytecode &harr; mcode) to support deoptimization.
910Much more flexible and needs only 50% of the space.</li>
911<li>The modules <tt>jit.trace</tt>, <tt>jit.dumphints</tt> and
912<tt>jit.dump</tt> handle deoptimization.</li>
913</ul></li>
914
915<li>Inlined many popular library functions
916(for commonly used arguments only):
917<ul>
918<li>Most <tt>math.*</tt> functions (the 18 most used ones)
919[2x-10x faster].</li>
920<li><tt>string.len</tt>, <tt>string.sub</tt> and <tt>string.char</tt>
921[2x-10x faster].</li>
922<li><tt>table.insert</tt>, <tt>table.remove</tt> and <tt>table.getn</tt>
923[3x-5x faster].</li>
924<li><tt>coroutine.yield</tt> and <tt>coroutine.resume</tt>
925[3x-5x faster].</li>
926<li><tt>pairs</tt>, <tt>ipairs</tt> and the corresponding iterators
927[8x-15x faster].</li>
928</ul></li>
929
930<li>Changes in the core and loadable modules and the stand-alone executable:
931<ul>
932<li>Added <tt>jit.version</tt>, <tt>jit.version_num</tt>
933and <tt>jit.arch</tt>.</li>
934<li>Reorganized some internal API functions (<tt>jit.util.*mcode*</tt>).</li>
935<li>The <tt>-j dump</tt> output now shows JSUB names, too.</li>
936<li>New x86 disassembler module written in pure Lua. No dependency
937on ndisasm anymore. Flexible API, very compact (500 lines)
938and complete (x87, MMX, SSE, SSE2, SSE3, SSSE3, privileged instructions).</li>
939<li><tt>luajit -v</tt> prints the LuaJIT version and copyright
940on a separate line.</li>
941</ul></li>
942
943<li>Added SSE, SSE2, SSE3 and SSSE3 support to DynASM.</li>
944<li>Miscellaneous doc changes. Added a section about
945<a href="install.html#embedding">embedding LuaJIT</a>.</li>
946</ul>
