However, it's a bit of a nuisance for this profiling to only be toggle-able at build time. In order to allow switching allocation profiling extensions on or off more conveniently, let's add a new option to JSC reserved for use in allocation profiling extensions. The main value of this option is that it will communicate its value through the additional bytes of g_config reserved in https://bugs.webkit.org/show_bug.cgi?id=266110, so it may be linked against and queried in the libPAS/bmalloc layer via external reference to g_config, unlike other JSC options which are managed at a later stage and have a C++ interface. 2014212 1 d_degazio 2024-02-15 16:20:00 -0800 Pull request: https://github.com/WebKit/WebKit/pull/24561 2014524 2 ews-feeder 2024-02-16 09:36:33 -0800 Committed 274842@main (f76e442c710f): <https://commits.webkit.org/274842@main> Reviewed commits have been landed.
