* 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).

* 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).
