<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
|
||||
<a href="install.html#embedding">embedding LuaJIT</a>.</li>
|
||||
</ul>
|
||||
