From 8d3dd39d885f427faf3898521e7e1e9319d76b91 Mon Sep 17 00:00:00 2001 From: Samuel Holland Date: Fri, 22 Mar 2019 17:08:06 -0500 Subject: [PATCH] Correct minimum system LLVM version in tests Since commit 9452a8dfa3ba, the new debug info format is only generated for LLVM 8 and newer versions. However, the tests still assume that LLVM 7 will use the new debug info format. Fix the tests (and a comment in the code) to match the actual version check. --- src/librustc_codegen_llvm/debuginfo/metadata.rs | 8 +++++--- src/test/codegen/enum-debug-clike.rs | 2 +- src/test/codegen/enum-debug-niche-2.rs | 2 +- src/test/codegen/enum-debug-niche.rs | 2 +- src/test/codegen/enum-debug-tagged.rs | 2 +- src/test/debuginfo/borrowed-enum.rs | 2 +- .../debuginfo/generic-enum-with-different-disr-sizes.rs | 2 +- src/test/debuginfo/generic-struct-style-enum.rs | 2 +- src/test/debuginfo/generic-tuple-style-enum.rs | 2 +- src/test/debuginfo/recursive-struct.rs | 2 +- src/test/debuginfo/struct-style-enum.rs | 2 +- src/test/debuginfo/tuple-style-enum.rs | 2 +- src/test/debuginfo/unique-enum.rs | 2 +- 13 files changed, 17 insertions(+), 15 deletions(-) diff --git a/src/librustc_codegen_llvm/debuginfo/metadata.rs b/src/librustc_codegen_llvm/debuginfo/metadata.rs index ddcbf29da832b..8efa025e3dd9d 100644 --- a/src/librustc_codegen_llvm/debuginfo/metadata.rs +++ b/src/librustc_codegen_llvm/debuginfo/metadata.rs @@ -1156,12 +1156,14 @@ fn prepare_union_metadata( // Enums //=----------------------------------------------------------------------------- -// DWARF variant support is only available starting in LLVM 7. +// DWARF variant support is only available starting in LLVM 8. // Although the earlier enum debug info output did not work properly // in all situations, it is better for the time being to continue to // sometimes emit the old style rather than emit something completely -// useless when rust is compiled against LLVM 6 or older.
