From 8323008c642b50b3d3d1258ce87bae40c79df55e Mon Sep 17 00:00:00 2001 From: Roland McGrath Date: Fri, 27 Sep 2002 07:29:51 +0000 Subject: * elf/dl-addr.c (_dl_addr): Set dli_fbase to l_map_start unconditionally. Set dli_fname to _dl_argv[0] only for main program. 2002-09-27 Roland McGrath * elf/dl-addr.c (_dl_addr): Add a cast. * sysdeps/x86_64/dl-machine.h (elf_machine_rela) [USE_TLS]: Handle new TLS relocs R_X86_64_DTPMOD64, R_X86_64_DTPOFF64, and R_X86_64_TPOFF64. * elf/elf.h (R_X86_64_DTPMOD64, R_X86_64_DTPOFF64, R_X86_64_TPOFF64, R_X86_64_TLSGD, R_X86_64_TLSLD, R_X86_64_DTPOFF32, R_x86_64_GOTTPOFF, R_X86_64_TPOFF32): New macros.
