The opcodes were renamed long ago, but the macros were still using the old syntax. This CL was created using the following script (for WASM_GET_GLOBAL and WASM_SET_GLOBAL): ag -l WASM_GET_GLOBAL | xargs -L 1 sed -i 's/\bWASM_GET_GLOBAL\b/WASM_GLOBAL_GET/g' R=ahaas@chromium.org Bug: v8:11074 Change-Id: I3a9bd64f6e09ce97dae6d4132c224350dc079c0f Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/2597576 Commit-Queue: Clemens Backes <clemensb@chromium.org> Reviewed-by: Andreas Haas <ahaas@chromium.org> Cr-Commit-Position: refs/heads/master@{#71836}
