This is the most +efficient setting for full builds but makes incremental builds slow. +This release adds a new option `unity_size` which specifies how many +source files should be put in each unity file. + +The default value for block size is 4. This means that if you have a +target that has eight source files, Meson will generate two unity +files each of which includes four source files. The old behaviour can +be replicated by setting `unity_size` to a large value, such as 10000. |
