As it is right now in master, there is no difference between natural alignment and preferred alignment for AIX. The tentative direction is to use preferred alignment to record the actual alignment on AIX, but it is not finalized yet. I would rather leave this part of the work for the patch that's going to implement the power alignment rule for AIX. ================ Comment at: clang/test/CodeGen/aix-vaargs.c:3 +// REQUIRES: asserts +// RUN: %clang_cc1 -triple powerpc-unknown-aix -emit-llvm -o - %s | FileCheck %s --check-prefixes=AIX-COM,AIX-M32 +// RUN: %clang_cc1 -triple powerpc64-unknown-aix -emit-llvm -o - %s | FileCheck %s --check-prefixes=AIX-COM,AIX-M64 ---------------- Xiangling_L wrote: > Consistent with other testcases to use `AIX32/AIX64`? I chose AIX-M32/AIX-M64 mainly because the length is the same as AIX-COM so we don't need to worry about aligning the space. I would prefer to keep it that.
