While LLVM now supports both ELFv1 and ELFv2 ABIs, their use is currently hard-coded via the target triple: powerpc64-linux is always ELFv1, while powerpc64le-linux is always ELFv2. These are of course the most common scenarios, but in principle it is possible to support the ELFv2 ABI on big-endian or the ELFv1 ABI on little-endian systems (and GCC does support that), and there are some special use cases for that (e.g. certain Linux kernel versions could only be built using ELFv1 on LE). This patch implements the LLVM side of supporting this. As precedent on other platforms suggests, ABI options are passed to the back-end as features. Thus, this patch implements two features "elfv1" and "elfv2" that select the desired ABI if present. (If not, the LLVM uses the same default rules as now.) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@214072 91177308-0d34-0410-b5e6-96231b3b80d8 |
