Tunning will only add +`-Dcpu=whatever` which should override the standard behaviour. + +Zig by default uses `native`, which interferes with our build process. +In our previous zig-build-system we chose to add `-Dcpu=baseline` flag +in each `zig build` execution, but that doesn't allow us to tune the +package later. Tunning is only designed to add extra flags in the +command line call, and we already had one set for the baseline case. +With this patch we set the standard behavior to `baseline` so we don't +need to add the `-Dcpu=baseline` flag in the zig-build-system and we can +tune with no issues. +--- + lib/std/Target/Query.zig | 2 +- + 1 file changed, 1 insertion(+), 1 deletion(-) + +diff --git a/lib/std/Target/Query.zig b/lib/std/Target/Query.zig +index 56387c27b3..1c0f18f93d 100644 +--- a/lib/std/Target/Query.zig ++++ b/lib/std/Target/Query.zig +@@ -6,7 +6,7 @@ + /// `null` means native. + cpu_arch: ?Target.Cpu.Arch = null, + +-cpu_model: CpuModel = .determined_by_arch_os, ++cpu_model: CpuModel = .baseline, + + /// Sparse set of CPU features to add to the set from `cpu_model`. + cpu_features_add: Target.Cpu.Feature.Set = .empty, +-- +2.47.1 + |
