Daniel Bertalan 2b69af2dfe AK+LibJS: Handle NaN-boxing pointers on AArch64 ... JS::Value stores 48 bit pointers to separately allocated objects in its payload. On x86-64, canonical addresses have their top 16 bits set to the same value as bit 47, effectively meaning that the value has to be sign-extended to get the pointer. AArch64, however, expects the topmost bits to be all zeros. This commit gates sign extension behind `#if ARCH(X86_64)`, and adds an `#error` for unsupported architectures, so that we do not forget to think about pointer handling when porting to a new architecture. Fixes #15290 Fixes SerenityOS/ladybird#56		2022-09-21 11:55:57 +02:00
