[PATCH] D70718: [AIX] Replace ExternalSymbolSDNode with a MCSymbolSDNode for memcpy/memset/memmove

[Hubert Tong via Phabricator via llvm-commits]

hubert.reinterpretcast added inline comments.


================
Comment at: llvm/test/CodeGen/PowerPC/aix-external-sym-sdnode-lowering.ll:11
+entry:
+  call void @llvm.memcpy.p0i8.p0i8.i32(i8* %p, i8* %q, i32 %n, i1 false)
+  ret void
----------------
XL calls `.___memmove` (with three underscores) with no NOP to implement both `memcpy` and `memmove`. This is implemented in libc as an extended operation (with no TOC dependency). This is also the case with `.___memset` for `memset`.
