Andreas Kling	e3560c2545	LibJS/JIT: Propagate exceptions in the simplest case :^) ... We now establish a stack of "unwind contexts" similar to what the bytecode interpreter does, but here, it's a stack of structs with addresses to the catch and finally blocks. Unwind contexts also have a "valid" flag, and the root unwind context (always present, pushed on JIT code entry) has valid=false, which we interpret in check_exception() as "return and let our caller deal with the exception". Anything in Compiler that may generate an exception should now also call check_exception() ASAP to emit the code for handling this.	2023-10-27 19:07:22 +02:00

Andreas Kling	71e41418f6	LibJS/JIT: Do "enter & leave" sequence in x86_64 machine code ... This ensures that the stack pointer is restored before we return from the jitted code.	2023-10-27 19:07:22 +02:00
