This release is in sync with Coco 1.1.1 (see the

< h2 id = "LuaJIT-1.1.0" > LuaJIT 1.1.0 — 2006-03-13< / h2 >
< ul >
< li > Merged with Lua 5.1 (final).< / li >
< li > New JIT call frame setup:
< ul >
< li > The C stack is kept 16 byte aligned (faster).
Mandatory for Mac OS X on Intel, too.< / li >
< li > Faster calling conventions for internal C helper functions.< / li >
< li > Better instruction scheduling for function prologue, OP_CALL and
OP_RETURN.< / li >
< / ul > < / li >
< li > Miscellaneous optimizations:
< ul >
< li > Faster loads of FP constants. Remove narrow-to-wide store-to-load
forwarding stalls.< / li >
< li > Use (scalar) SSE2 ops (if the CPU supports it) to speed up slot moves
and FP to integer conversions.< / li >
< li > Optimized the two-argument form of < tt > OP_CONCAT< / tt > (< tt > a..b< / tt > ).< / li >
< li > Inlined < tt > OP_MOD< / tt > (< tt > a%b< / tt > ).
With better accuracy than the C variant, too.< / li >
< li > Inlined < tt > OP_POW< / tt > (< tt > a^b< / tt > ). Unroll < tt > x^k< / tt > or
use < tt > k^x = 2^(log2(k)*x)< / tt > or call < tt > pow()< / tt > .< / li >
< / ul > < / li >
< li > Changes in the optimizer:
< ul >
< li > Improved hinting for table keys derived from table values
(< tt > t1[t2[x]]< / tt > ).< / li >
< li > Lookup hinting now works with arbitrary object types and
supports index chains, too.< / li >
< li > Generate type hints for arithmetic and comparison operators,
OP_LEN, OP_CONCAT and OP_FORPREP.< / li >
< li > Remove several hint definitions in favour of a generic COMBINE hint.< / li >
< li > Complete rewrite of < tt > jit.opt_inline< / tt > module
(ex < tt > jit.opt_lib< / tt > ).< / li >
< / ul > < / li >
< li > Use adaptive deoptimization:
< ul >
< li > If runtime verification of a contract fails, the affected
instruction is recompiled and patched on-the-fly.
Regular programs will trigger deoptimization only occasionally.< / li >
< li > This avoids generating code for uncommon fallback cases
most of the time. Generated code is up to 30% smaller compared to
LuaJIT 1.0.3.< / li >
< li > Deoptimization is used for many opcodes and contracts:
< ul >
< li > OP_CALL, OP_TAILCALL: type mismatch for callable.< / li >
< li > Inlined calls: closure mismatch, parameter number and type mismatches.< / li >
< li > OP_GETTABLE, OP_SETTABLE: table or key type and range mismatches.< / li >
< li > All arithmetic and comparison operators, OP_LEN, OP_CONCAT,
OP_FORPREP: operand type and range mismatches.< / li >
< / ul > < / li >
< li > Complete redesign of the debug and traceback info
(bytecode ↔ mcode) to support deoptimization.
Much more flexible and needs only 50% of the space.< / li >
< li > The modules < tt > jit.trace< / tt > , < tt > jit.dumphints< / tt > and
< tt > jit.dump< / tt > handle deoptimization.< / li >
< / ul > < / li >
< li > Inlined many popular library functions
(for commonly used arguments only):
< ul >
< li > Most < tt > math.*< / tt > functions (the 18 most used ones)
[2x-10x faster].< / li >
< li > < tt > string.len< / tt > , < tt > string.sub< / tt > and < tt > string.char< / tt >
[2x-10x faster].< / li >
< li > < tt > table.insert< / tt > , < tt > table.remove< / tt > and < tt > table.getn< / tt >
[3x-5x faster].< / li >
< li > < tt > coroutine.yield< / tt > and < tt > coroutine.resume< / tt >
[3x-5x faster].< / li >
< li > < tt > pairs< / tt > , < tt > ipairs< / tt > and the corresponding iterators
[8x-15x faster].< / li >
< / ul > < / li >
< li > Changes in the core and loadable modules and the stand-alone executable:
< ul >
< li > Added < tt > jit.version< / tt > , < tt > jit.version_num< / tt >
and < tt > jit.arch< / tt > .< / li >
< li > Reorganized some internal API functions (< tt > jit.util.*mcode*< / tt > ).< / li >
< li > The < tt > -j dump< / tt > output now shows JSUB names, too.< / li >
< li > New x86 disassembler module written in pure Lua. No dependency
on ndisasm anymore. Flexible API, very compact (500 lines)
and complete (x87, MMX, SSE, SSE2, SSE3, SSSE3, privileged instructions).< / li >
< li > < tt > luajit -v< / tt > prints the LuaJIT version and copyright
on a separate line.< / li >
< / ul > < / li >
< li > Added SSE, SSE2, SSE3 and SSSE3 support to DynASM.< / li >
< li > Miscellaneous doc changes. Added a section about
