I'm not sure if gccint is designed for normal users to read, but since we lack a documentation about those descriptors in GCC user manual, I guess many users will indeed use gccint as a reference ... Ok to me. But regarding the test case I suggest to keep those "%a" tests there (so we won't inadvertently cause a regression in case some user code already uses it for printing an integer). Unless we deliberately want to stop people from using "%a" for this purpose. -- Xi Ruoyao <xry...@xry111.site> School of Aerospace Science and Technology, Xidian University
