Subject: [WebAssembly] Remove old intrinsics
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=7bc85db61e92de3f5e9b984cfa7ee0f881a968ec;p=llvm

[WebAssembly] Remove old intrinsics

This removes the old grow_memory and mem.grow-style intrinsics, leaving just
the memory.grow-style intrinsics.

Differential Revision: https://reviews.llvm.org/D56645


git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@351084 91177308-0d34-0410-b5e6-96231b3b80d8
