Subject: [PATCH] Use `baseline` cpu by default.
|
|
|
|
This helps Guix tune the package later. 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.
