From 2e4dafd94f1413a3199eee30c6eb4ed44dc27d18 Mon Sep 17 00:00:00 2001
From: Daniel Golle <daniel@makrotopia.org>
Date: Wed, 23 Sep 2026 14:33:27 +0100
Subject: [PATCH] JavaScriptCore: add RISCV64 to the IPInt asm WEBASSEMBLY
guards
InPlaceInterpreter.asm gates the IPInt entry, catch and table-catch
trampolines on an explicit architecture list, and selects the 64-bit
implementation file the same way. RISCV64 is absent from every one of
them, so no IPInt code is emitted at all.
Add RISCV64 to those guards and to the JSVALUE64 include of
InPlaceInterpreter64.
