Xmake v2.3.2 is released, bringing the same construction speed as ninja


This version focuses on refactoring and optimizing the internal parallel construction mechanism, realizing the parallel compilation of source files between multiple targets and the support of parallel links. At the same time, it optimizes some internal losses of xmake and fixes some bugs affecting the compilation speed.
Through test and comparison, the current overall construction speed is basically the same as that of ninja. Compared with cmake / make, meson / Ninja are much faster, because they have an additional step in the process of generating makefile / build.ninja.

In addition, xmake also adds support for Sdcc compilation tool chain, which is used to compile embedded programs such as 51 / stm8.

Some optimization points

  1. All source files between multiple targets are built in parallel at the same time (previously, they cannot cross targets, and they will be blocked and serialized by links in the middle)
  2. Multiple independent target links can be executed in parallel (previously, only one link can be executed one by one)
  3. Fix the previous task scheduling bug, make more fine-grained scheduling, and make full use of CPU core resources
  4. The effect of optimizing some losses on xmake’s internal API is also obvious

For more optimization details, see issue #589

Construction speed comparison

We have done some comparative tests on termux and MacOS. The test project is xmake core

For a relatively large number of target projects, the new version of xmake has significantly improved its construction speed.
