3302d7a45504 [JSC] Preallocate SourceProviderCache::m_map
not a security fix
confidence 0.1
signal score 8.6
Source/JavaScriptCore/runtime
Classified as not security-relevant.
Triage note: Gives SourceProviderCache a create(sourceLength) that reserveInitialCapacity() on the map with a capped estimate. Parser cache performance optimization, not security.
