As per <https://sourceware.org/ml/libc-alpha/2014-10/msg00369.html>, there should not be separate sysdeps/<arch>/soft-fp directories when those are used by all configurations that use sysdeps/<arch>, and, more generally, should not be sysdeps/foo/Implies files pointing to a subdirectory foo/bar. This patch eliminates the sysdeps/alpha/soft-fp directory accordingly, merging its contents into sysdeps/alpha. Tested with build-many-glibcs.py that installed stripped shared libraries for alpha-linux-gnu are unchanged by this patch. * sysdeps/alpha/Implies: Remove alpha/soft-fp. * sysdeps/alpha/Makefile [$(subdir) = soft-fp] (sysdep_routines): Add functions moved from .... [$(subdir) = math] (CPPFLAGS): Add -I../soft-fp. Moved from .... * sysdeps/alpha/soft-fp/Makefile: ... here. Remove file. * sysdeps/alpha/Versions (libc): Add GLIBC_2.3.4 symbols moved from .... * sysdeps/alpha/soft-fp/Versions: ... here. Remove file. * sysdeps/alpha/soft-fp/e_sqrtl.c: Move to .... * sysdeps/alpha/e_sqrtl.c: ... here. * sysdeps/alpha/soft-fp/local-soft-fp.h: Move to .... * sysdeps/alpha/local-soft-fp.h: ... here. * sysdeps/alpha/soft-fp/ots_add.c: Move to .... * sysdeps/alpha/ots_add.c: ... here. * sysdeps/alpha/soft-fp/ots_cmp.c: Move to .... * sysdeps/alpha/ots_cmp.c: ... here. * sysdeps/alpha/soft-fp/ots_cmpe.c: Move to .... * sysdeps/alpha/ots_cmpe.c: ... here. * sysdeps/alpha/soft-fp/ots_cvtqux.c: Move to .... * sysdeps/alpha/ots_cvtqux.c: ... here. * sysdeps/alpha/soft-fp/ots_cvtqx.c: Move to .... * sysdeps/alpha/ots_cvtqx.c: ... here. * sysdeps/alpha/soft-fp/ots_cvttx.c: Move to .... * sysdeps/alpha/ots_cvttx.c: ... here. * sysdeps/alpha/soft-fp/ots_cvtxq.c: Move to .... * sysdeps/alpha/ots_cvtxq.c: ... here. * sysdeps/alpha/soft-fp/ots_cvtxt.c: Move to .... * sysdeps/alpha/ots_cvtxt.c: ... here. * sysdeps/alpha/soft-fp/ots_div.c: Move to .... * sysdeps/alpha/ots_div.c: ... here. * sysdeps/alpha/soft-fp/ots_mul.c: Move to .... * sysdeps/alpha/ots_mul.c: ... here. * sysdeps/alpha/soft-fp/ots_nintxq.c: Move to .... * sysdeps/alpha/ots_nintxq.c: ... here. * sysdeps/alpha/soft-fp/ots_sub.c: Move to .... * sysdeps/alpha/ots_sub.c: ... here. * sysdeps/alpha/soft-fp/sfp-machine.h: Move to .... * sysdeps/alpha/sfp-machine.h: ... here.
