* RegExp: Do on demand JIT compilationFabian Kosmale2024-02-131-0/+2
| | | | | | | | | | | | | | | | | | | | | | | JIT compiling means that we need to obtain executable memory for the jitted code. That has a non-neglibile cost (in addition to the runtime cost of compiling the pattern). Thus, only compile the pattern if we suspect it to be worthwhile: - when we called match multiple times - or when the string we match against is quite large We also assume that the JIT generally works, and thus discard the bytecode immediately before jitting – if the JIT fails once (either to compile, or with offset failure), we recompile the bytecode and never JIT this pattern again. Amends commit 04820be3011395bd5cb13dea8f81c9b9bca4da8f.

* | New mark table implementationLars Knoll2017-03-091-2/+0
|/ | | | | | | | | | | | | | | | | | | Automatically generate a table containing the data where JS Values and pointers are in objects in the JS heap. This will allow making the GC mark phase a lot more efficient. A bit of a special hack is currently required for MemberData and ArrayData, as they have a variable length, and we need to read the size from the object. We keep backwards compatibility with the old markObjects() functions for now (calling them if they are defined). Some further work on QV4::String and in a few other places is required before we can get remove the compatibility.
