From 351e2b5aa7a71258e6b682ac1a3228964de8d22c Mon Sep 17 00:00:00 2001 From: Dave Anglin Date: Wed, 28 Apr 2004 18:02:49 +0000 Subject: * som.c (struct som_misc_symbol_info): Add is_comdat, is_common and dup_common fields. (setup_sections): Use som_subspace_dictionary_record struct instead subspace_dictionary_record. Set SEC_LINK_ONCE if subspace is is_comdat, is_common or dup_common. (som_prep_headers): Use som_subspace_dictionary_record struct. Set is_comdat, is_common and dup_common in section subspace_dict from copy_data. (som_begin_writing): Use som_subspace_dictionary_record struct. (som_finish_writing): Likewise. (som_bfd_derive_misc_symbol_info): Add support to set is_comdat, is_common and dup_common flags in info for symbol. Add comment regarding linker support for these fields. Slightly reorganize function. (som_build_and_write_symbol_table): Set is_comdat, is_common and dup_common fields in symbol table from symbol info. (bfd_som_set_subsection_attributes): Add comdat, common and dup_common arguments. Set corresponding fields in copy_data. Change all callers. (som_bfd_ar_write_symbol_stuff): Set dup_common flag in library symbol table. (som_vec): Add SEC_LINK_ONCE to applicable section flags. * som.h (som_subspace_dictionary_record): Define. (som_copyable_section_data_struct): Add is_comdat, is_common and dup_common fields. (som_section_data_struct): Use som_subspace_dictionary_record struct instead of subspace_dictionary_record. (bfd_boolean bfd_som_set_subsection_attributes): Adjust prototype. * config/obj-som.c (obj_som_init_stab_section): Add new arguments in call to obj_set_subsection_attributes. (obj_som_init_stab_section): Likewise. * config/tc-hppa.c (default_subspace_dict): Add comdat field. (pa_def_subspaces): Provide comdat default. (pa_subspace): Handle new "comdat" parameter. Set SEC_LINK_ONCE and not SEC_IS_COMMON if section is comdat, common or dup_common. Update calls to create_new_subspace and update_subspace to pass comdat flag. (create_new_subspace, update_subspace): Add new comdat argument. Use it in calls to obj_set_subsection_attributes. * doc/c-hppa.texi (.subspa, .nsubspa): Document new comdat parameter and use of comdat, common and dup_comm parameters. --- bfd/som.h | 38 +++++++++++++++++++++++++++++++++++--- 1 file changed, 35 insertions(+), 3 deletions(-) (limited to 'bfd/som.h') diff --git a/bfd/som.h b/bfd/som.h index 537ddaa..3954855 100644 --- a/bfd/som.h +++ b/bfd/som.h @@ -27,7 +27,7 @@ #include "libhppa.h" -/* Enable PA2.0 if available */ +/* We want reloc.h to provide PA 2.0 defines. */ #define PA_2_0 #include @@ -143,6 +143,35 @@ struct som_data_struct struct somdata a; }; +struct som_subspace_dictionary_record + { + int space_index; + unsigned int access_control_bits : 7; + unsigned int memory_resident : 1; + unsigned int dup_common : 1; + unsigned int is_common : 1; + unsigned int is_loadable : 1; + unsigned int quadrant : 2; + unsigned int initially_frozen : 1; + unsigned int is_first : 1; + unsigned int code_only : 1; + unsigned int sort_key : 8; + unsigned int replicate_init : 1; + unsigned int continuation : 1; + unsigned int is_tspecific : 1; + unsigned int is_comdat : 1; + unsigned int reserved : 4; + int file_loc_init_value; + unsigned int initialization_length; + unsigned int subspace_start; + unsigned int subspace_length; + unsigned int reserved2 : 5; + unsigned int alignment :27; + union name_pt name; + int fixup_request_index; + unsigned int fixup_request_quantity; + }; + /* Substructure of som_section_data_struct used to hold information which can't be represented by the generic BFD section structure, but which must be copied during objcopy or strip. */ @@ -155,6 +184,9 @@ struct som_copyable_section_data_struct unsigned int is_defined : 1; unsigned int is_private : 1; unsigned int quadrant : 2; + unsigned int is_comdat : 1; + unsigned int is_common : 1; + unsigned int dup_common : 1; /* For subspaces, this points to the section which represents the space in which the subspace is contained.
