From 96a72676d1134f58c378b0b8003922b09b9f1e5f Mon Sep 17 00:00:00 2001 From: Erik Desjardins Date: Sun, 25 Feb 2024 00:43:03 -0500 Subject: [PATCH] use [N x i8] for byval/sret types This avoids depending on LLVM's struct types to determine the size of the byval/sret slot. --- compiler/rustc_codegen_llvm/src/abi.rs | 20 ++++- tests/codegen/align-byval-vector.rs | 8 +-
