debdb32ef3 Bug 480132: Clone lexical blocks only when needed. r=igor
Terminology:

A "script block" is an object of class Block allocated by the byte
compiler and associated with a script.  Script blocks are never
modified, and may be used as a prototype for a "closure block":

A "closure block" is an object of class Block that holds variables
that have been closed over (although we actually leave the variables
on the stack until we leave their dynamic scope).  A closure block is
a clone of a script block (its prototype is a script block).

Adjust the meanings of fp->blockChain and fp->scopeChain:

  fp->blockChain is always the innermost script block in whose static
  scope we're executing.

  fp->scopeChain is the current scope chain, including 'call' objects
  and closure blocks for those function calls and blocks in whose
  static scope we are currently executing, and 'with' objects for with
  statements; the chain is typically terminated by a global object.
  However, as an optimization, the young end of the chain omits block
  objects we have not yet needed to clone.

Closures need fully reified scope chains, so have js_GetScopeChain
reify any closure blocks missing from the young end of fp->scopeChain
by cloning script blocks as needed from fp->blockChain.  Thus, if we
never actually close over a particular block, we never place a closure
block for it on fp->scopeChain.

Have JSOP_ENTERBLOCK and JSOP_LEAVEBLOCK always keep fp->blockChain
current.  When JSOP_LEAVEBLOCK pops a block from fp->blockChain that
has been cloned on fp->scopeChain, pop fp->scopeChain as well.

Remove the JSFRAME_POP_BLOCKS flag, as it is no longer needed.

Ensure that the JIT won't have to create closure blocks or call
js_PutBlockObject; it can't handle those things yet.  Note our current
script block when we begin recording.  Abort recording if we leave
that block; we can't tell in advance whether it will need to be "put"
in future trace invocations.  Leave trace if we call js_GetScopeChain
while in the static scope of lexical blocks.  Remove JIT tests based
on JSFRAME_POP_BLOCKS.

Verify that generators capture the correct value for blockChain.

Add a constructor to JSAutoTempValueRooter for rooting JSObject
pointers.

c92c2000cc Bug 461050 WIP: compiling simple regexps, r=danderson,agal 2008-11-04 14:51:51 -08:00
Andreas Gal
25404443ff GC no longer flushes the JIT cache. Instead just make sure the shape of the global object will mismatch next time we try to record or execute code, which in turn will force a flush of the code cache (458288, r=brendan/danderson). 2008-10-28 16:22:08 -07:00

90bf6a2d1e Bug 97954: Give jsconfig.h a better name, and make room for the new js-config.h. r=bsmedberg
We'd like the SpiderMonkey configure script to generate a header file
named js-config.h to hold #definitions chosen at configure time that
affect the SpiderMonkey API, like JS_THREADSAFE.  However, that name
is very similar to that of an existing header file, jsconfig.h.  This
patch renames the existing header file, and updates all references to
it.

rename : js/src/jsconfig.h => js/src/jsversion.h

d56e272e19 * Menu of -D flags for enabling instrumentation, as a commented-out CFLAGS += setting for convenient testing. * js_FindProperty and js_LookupPropertyWithFlags return indexes into the scope and prototype chains, respectively, to support internal instrumentation, and to pave the way for the return of the property cache (bug 365851).. * jsutil.[ch] JSBasicStats struct and functions for computing mean/sigma/max and auto-scaling histogram. * JS_SCOPE_DEPTH_METER instrumentation for compile- and run-time scope chain length instrumentation: + At compile time, rt->hostenvScopeDepthStats and rt->lexicalScopeDepthStats meter scope chains passed into the compile and evaluate APIs. + At runtime, rt->protoLookupDepthStats and rt->scopeSearchDepthStats track steps along the prototype and scope chains until the sought-after property is found. * JS_ARENAMETER uses JSBasicStats now. * Added rt->liveScopePropsPreSweep to fix the property tree stats code that rotted when property tree sweeping moved to after the finalization phase. * Un-bitrotted some DEBUG_brendan code, turned some off for myself via XXX. * Mac OS X toolchain requires initialized data shared across dynamic library member files, outlaws common data, so initialize extern metering vars. * Old HASHMETER code in jshash.[ch] is now JS_HASHMETER-controlled and based on JSBasicStats. * DEBUG_scopemeters macro renamed JS_DUMP_SCOPE_METERS; uses JSBasicStats now. * Disentangle DEBUG and DUMP_SCOPE_STATS (now JS_DUMP_PROPTREE_STATS) and fix inconsistent thread safety for liveScopeProps (sometimes atomic-incremented, sometimes runtime-locked). * Compiler-modeled maxScopeDepth will propagate via JSScript to runtime for capability-based, interpreter-inlined cache hit qualifier bits, to bypass scope and prototype chain lookup by optimizing for common monomorphic get, set, and call site referencing a prototype property in a well-named object (no shadowing or mutation in 99.9% of the cases). 2008-01-12 16:31:31 -08:00
