Reverse libLTO's default behaviour for preserving use-list order in bitcode, and add API for controlling it. The default setting is now `false` (don't preserve them), which is consistent with `clang`'s default behaviour. Users of libLTO should call `lto_codegen_should_embed_uselists(CG,true)` prior to calling `lto_codegen_write_merged_modules()` whenever the output file isn't part of the production workflow in order to reproduce results with subsequent calls to `llc`. (I haven't added tests since `llvm-lto` (the test tool for LTO) doesn't support bitcode output, and even if it did: there isn't actually a good way to test whether a tool has passed the flag. If the order is already "natural" (if the order will already round-trip) then no use-list directives are emitted at all. At some point I'll circle back to add tests to `llvm-as` (etc.) that they actually respect the flag, at which point I can somehow add a test here as well.) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@235943 91177308-0d34-0410-b5e6-96231b3b80d8 |
