Update.
2002-04-08 kaz Kojima <kkojima@rr.iij4u.or.jp> * elf/elf.h: Define R_SH_TLS_xxx macros. * elf/rtld.c: Remove an extra parenthesis. * elf/tls-macros.h: Define SH version TLS_LE, TLS_IE, TLS_LD and TLS_GD macros. * sysdeps/generic/dl-tls.c: Add a missing semi-colon. * sysdeps/sh/dl-lookupcfg.h: New file. * sysdeps/sh/dl-tls.h: New file. * sysdeps/sh/dl-machine.h (elf_machine_type_class): Set ELF_RTYPE_CLASS_PLT also for the three TLS relocations. (elf_machine_rela): Handle R_SH_TLS_DTPMOD32, R_SH_TLS_DTPOFF32 and R_SH_TLS_TPOFF32 relocations.
