mlugg 92c63126e8 compiler: tlv pointers are not comptime-known ... Pointers to thread-local variables do not have their addresses known until runtime, so it is nonsensical for them to be comptime-known. There was logic in the compiler which was essentially attempting to treat them as not being comptime-known despite the pointer being an interned value. This was a bit of a mess, the check was frequent enough to actually show up in compiler profiles, and it was very awkward for backends to deal with, because they had to grapple with the fact that a "constant" they were lowering might actually require runtime operations. So, instead, do not consider these pointers to be comptime-known in *any* way. Never intern such a pointer; instead, when the address of a threadlocal is taken, emit an AIR instruction which computes the pointer at runtime. This avoids lots of special handling for TLVs across basically all codegen backends; of all somewhat-functional backends, the only one which wasn't improved by this change was the LLVM backend, because LLVM pretends this complexity around threadlocals doesn't exist. This change simplifies Sema and codegen, avoids a potential source of bugs, and potentially improves Sema performance very slightly by avoiding a non-trivial check on a hot path.		2025-05-27 19:23:11 +01:00
