2003-10-14 Bob Wilson <bob.wilson@acm.org> * elf32-xtensa.c (get_is_linkonce_section): Delete. (xtensa_is_property_section, xtensa_is_littable_section): Use XTENSA_INSN_SEC_NAME and XTENSA_LIT_SEC_NAME macros. Do not recognize linkonce sections containing ".xt.insn" and ".xt.lit" substrings. (xtensa_get_property_section_name): Check section name instead of calling get_is_linkonce_section. Remove unused bfd parameter. Use XTENSA_INSN_SEC_NAME and XTENSA_LIT_SEC_NAME macros. Never generate linkonce section names by appending ".xt.insn" or ".xt.lit". (xtensa_read_table_entries): Remove bfd argument in call to xtensa_get_property_section_name. Free section name when done. (elf_xtensa_combine_prop_entries): Free leaking table. gas ChangeLog: 2003-10-14 Bob Wilson <bob.wilson@acm.org> * config/tc-xtensa.c (xtensa_create_property_segments): Remove bfd argument in call to xtensa_get_property_section_name. Formatting. include ChangeLog: 2003-10-14 Bob Wilson <bob.wilson@acm.org> * elf/xtensa.h: Formatting. Fix comments about property section names for linkonce sections.
