From e4e11b1dba261cb650e631978622bf3b4a4d8c37 Mon Sep 17 00:00:00 2001 From: Adhemerval Zanella Date: Wed, 22 Apr 2020 11:02:11 -0300 Subject: signal: Add signum-{generic,arch}.h It refactor how signals are defined by each architecture. Instead of include a generic header (bits/signum-generic.h) and undef non-default values in an arch specific header (bits/signum.h) the new scheme uses a common definition (bits/signum-generic.h) and each architectures add its specific definitions on a new header (bits/signum-arch.h). For Linux it requires copy some system default definitions to alpha, hppa, and sparc. They are historical values and newer ports uses the generic Linux signum-arch.h. For Hurd the BSD signum is removed and moved to a new header (it is used currently only on Hurd). Checked on a build against all affected ABIs.
