From 8696b2db7095e8387ef7ca145cd8541a6e9ee547 Mon Sep 17 00:00:00 2001 From: Ian Lance Taylor Date: Fri, 14 Feb 1997 02:13:19 +0000 Subject: [PATCH] Thu Feb 13 20:53:22 1997 Klaus Kaempf (kkaempf@progis.de) * reloc.c (BFD_RELOC_ALPHA_CODEADDR): New relocation for openVMS/Alpha. * evax.h (ALPHA_R_CODEADDR): New relocation. * evax-alpha.c (ALPHA_R_CODEADDR): 64 bit procedure relocation for openVMS/Alpha. * evax-etir.c (ALPHA_R_CODEADDR): Output object code for this relocation. * bfd-in2.h, libbfd.h: Rebuild. Restrict symbol length to 64 bytes, case preserving: * evax-emh.c (_bfd_evax_write_emh): Remove case hacking. * evax-misc.c (_bfd_evax_case_hack_symbol): Remove. (_bfd_evax_length_hash_symbol): Added. * evax-etir.c (_bfd_evax_write_etir): Call _bfd_evax_length_hash_symbol before output of symbol. * evax-egsd.c (_bfd_evax_write_egsd): Likewise. * evax.h (flag_hash_long_names, flag_show_after_trunc): Remove. * evax-emh.c: Output filename to object file without path. * evax-egsd.c: New sections for local and global commons. * evax-alpha.c, evax-emh.c, evax-egsd.c, evax-etir.c, evax-misc.c, evax.h: Remove 8 bit characters from copyright notices.
