Hello, I am starting (hopefully small) serie of patches to support new ABI dedicated for Intel's MicroController Units [1].
Support for new arch was introduced into Binutils in a few threads, e.g. [2]. This patchset includes: - Support in GCC: new switch (-miamcu), macro etc. - Changes to libraries. - Testsuite. Whole patch is in the bottom.
