Debian arch names are the result of +# historical naming conventions in Debian, where the predominant system +# architectures have many of their parts in implicit form, by only exposing +# the CPU with the ABI bolted on, where less common architectures have their +# OS part spelled out, and where even less common ones, have their libc +# spelled out. This table maps between the ideal architecture tuple, with +# the current messy reality. +# +# - Column 1 is the Debian arch tuple name, as the normalized form of the +# architecture names, used as the internal representation. +# - Column 2 is the Debian arch name, as the abbreviated form of the +# architecture names, used as the public interface. +# # Supported variables: <cpu> # # <Debian arch tuple> <Debian arch name> |
