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/zig/CrossTarget.zig | 2 +- + 1 file changed, 1 insertion(+), 1 deletion(-) + +diff --git a/lib/std/zig/CrossTarget.zig b/lib/std/zig/CrossTarget.zig +index 6c59a4a3a..f5ec065fe 100644 +--- a/lib/std/zig/CrossTarget.zig ++++ b/lib/std/zig/CrossTarget.zig +@@ -12,7 +12,7 @@ const mem = std.mem; + /// `null` means native. + cpu_arch: ?Target.Cpu.Arch = null, + +-cpu_model: CpuModel = CpuModel.determined_by_cpu_arch, ++cpu_model: CpuModel = CpuModel.baseline, + + /// Sparse set of CPU features to add to the set from `cpu_model`. + cpu_features_add: Target.Cpu.Feature.Set = Target.Cpu.Feature.Set.empty, +-- +2.41.0 + |
