From e153c0c3393b2cb21c75b46e791c593479e07093 Mon Sep 17 00:00:00 2001 From: Trinity Bee Date: Wed, 16 Sep 2026 19:18:29 +0000 Subject: [PATCH] Implement part 1 of 2 of empty bodies in specs/vm/jit_semantics.t27 Implemented 8 functions with empty bodies: - initCompiler - deinitCompiler - resetCompiler - compileOperation - finalizeCompiler - codeSize - initCache - deinitCache Added test blocks for each implemented function.
