From: Deepesh Varatharajan <[email protected]> The data layout for x86-64 target was different in rust from llvm. It resulted in the following data layout error: -------------------------------------------------------------------------------------- error: data-layout for target `x86_64-linux`, `e-m:e-i64:64-f80:128-n8:16:32:64-S128`, differs from LLVM target's `x86_64-unknown-linux-gnu` default layout, `e-m:e-p270:32:32-p271:32:32-p272:64:64-i64:64-i128:128-f80:128-n8:16:32:64-S128` --------------------------------------------------------------------------------------
The issue was reported in meta-rust layer as: https://github.com/meta-rust/meta-rust/pull/442 Hence, the data layout for x86-64 is modified as per the llvm sources which fixes the issue. After running the testsuite with the modified data layout; it was observed that the "tests/codegen/i128-x86-align.rs" passed. The modified data layout fixed the scalar pair which resolved the testcase failure. Hence, the testcase has been removed from the exclude list.
