* 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 <roland@redhat.com>
* 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.
(R_X86_64_NUM): Update the value.
