2005-02-10 Roland McGrath <roland@redhat.com> [BZ #632] * scripts/soversions.awk: Expect cpu, vendor, os as separate variables from command line. Grok shlib-versions lines with WORDSIZE* in second column. Add new leading column to output, DEFAULT for existing output lines. Also emit lines with WORDSIZE* for alternate configurations. * Makeconfig ($(common-objpfx)soversions.i): Pass those variables. ($(common-objpfx)soversions.mk): Grok new column, use only DEFAULT. ($(common-objpfx)gnu/lib-names.stmp): Depend on soversions.i instead of soversions.mk; replace inline shell script with use of ... * scripts/lib-names.awk: New file. If input has non-DEFAULT lines, emit multiple sets of macros under #if. * shlib-versions (x86_64-.*-.*): Add WORDSIZE32 line mapping to i686. (s390x-.*-.*): Likewise for s390. (powerpc64-.*-.*): Likewise for powerpc. (sparc64-.*-.*): Likewise for sparc.
