From cd65a15d81b32636c5097200446cc6d6afc7199b Mon Sep 17 00:00:00 2001 From: Yawning Angel Date: Fri, 15 Dec 2023 17:29:59 +0900 Subject: src: `enable_target_feature` should add features, not overwrite `llvm_features` being empty is the default state, and implies the presence of certain features. Previously if any target features were explicitly enabled by the `enable_target_feature` attribute, they were added comma separated to `llvm_features`. For example: `lzcnt,popcnt,...,sse4.2,sse` This was causing LLVM to try to target a CPU that *ONLY* has the explicitly enabled features. This now will prefix explicitly enabled features with a `+`, and preserve the existing `llvm_features` string by appending to it if it is set. --- src/llvm_backend.cpp | 41
