Andreas Kling	9f822345bf	LibJS: Flatten Operand to 32-bit index in bytecode instruction stream ... While we're in the bytecode compiler, we want to know which type of Operand we're dealing with, but once we've generated the bytecode stream, we only ever need its index. This patch simplifies Operand by removing the aarch64 bitfield hacks and makes it 32-bit on all platforms. We keep 3 type bits in the high bits of the index while compiling, and then zero them out when flattening the final bytecode stream. This makes bytecode more compact on x86_64, and avoids bit twiddling on aarch64. Everyone wins something! When stringifying bytecode for debugging output, we now have an API in Executable that can look at a raw operand index and tell you what type of operand it was, based on known quantities of each type in the stack frame.	2025-12-09 21:44:13 -06:00
Andreas Kling	fb05063dde	LibJS: Let bytecode instructions know whether they are in strict mode ... This commits puts the strict mode flag in the header of every bytecode instruction. This allows us to check for strict mode without looking at the currently running execution context.	2025-10-29 21:20:10 +01:00
Shannon Booth	f87041bf3a	LibGC+Everywhere: Factor out a LibGC from LibJS ... Resulting in a massive rename across almost everywhere! Alongside the namespace change, we now have the following names: * JS::NonnullGCPtr -> GC::Ref * JS::GCPtr -> GC::Ptr * JS::HeapFunction -> GC::Function * JS::CellImpl -> GC::Cell * JS::Handle -> GC::Root	2024-11-15 14:49:20 +01:00

Shannon Booth	520aa04092	LibJS: Move Handle's Value specialization to Value header ... This is part of an effort to keep JS runtime specifics outside of the Heap implementation.	2024-11-13 11:08:35 +01:00
