From 9b472e85d098a40b84dd8b33fbf8a15ab1452025 Mon Sep 17 00:00:00 2001 From: Nick Desaulniers Date: Thu, 6 May 2021 18:04:54 -0700 Subject: gcov: clang: drop support for clang-10 and older LLVM changed the expected function signatures for llvm_gcda_start_file() and llvm_gcda_emit_function() in the clang-11 release. Drop the older implementations and require folks to upgrade their compiler if they're interested in GCOV support.
