From 604633aeca413d9fe75280b214894721f8186315 Mon Sep 17 00:00:00 2001 From: Ian Lance Taylor Date: Mon, 13 Sep 1993 21:32:07 +0000 Subject: [PATCH] * subsegs.c: Renamed non-BFD_ASSEMBLER subseg_new to subseg_set. Wrote non-BFD_ASSEMBLER subseg_new. Now subseg_new always takes a section name, and subseg_set always takes a segT. Changed all callers as appropriate. * config/obj-coffbfd.c (change_to_section): Renamed to obj_coff_add_segment. Corrected. Made callers use subseg_new. * config/obj-coffbfd.h (obj_segment_name, obj_add_segment): Define. Also some more gcc warning removal. --- gas/ChangeLog | 41 ++++ gas/as.h | 16 +- gas/config/obj-aout.c | 22 +- gas/config/obj-coffbfd.c | 202 +++++++++------- gas/config/obj-coffbfd.h | 40 ++-- gas/config/obj-elf.c | 83 ++++--- gas/config/obj-ieee.c | 10 +- gas/config/obj-vms.c | 2 +- gas/config/tc-a29k.c | 31 ++- gas/config/tc-i960.c | 7 +- gas/config/tc-m88k.c | 4 +- gas/config/tc-mips.c | 40 ++-- gas/read.c | 155 +++++-------- gas/subsegs.c | 594 +++++++++++++++++++++++++++-------------------- gas/symbols.c | 16 +- gas/write.h | 13 +- 16 files changed, 729 insertions(+), 547 deletions(-) diff --git a/gas/ChangeLog b/gas/ChangeLog index d986124..ca0ff4d 100644 --- a/gas/ChangeLog +++ b/gas/ChangeLog @@ -1,3 +1,44 @@ +Mon Sep 13 16:48:38 1993 Ian Lance Taylor (ian@tweedledumb.cygnus.com) + + * read.c (s_desc): Only compile and use if S_SET_DESC is defined. + * struc-symbol.h: Declare verify_symbol_chain and + verify_symbol_chain_2 even if not SYMBOLS_NEED_BACKPOINTERS. + * symbols.c (verify_symbol_chain): Removed useless expression. + * write.c (headers, the_object_file): Only use if not + BFD_ASSEMBLER and not BFD. + (fixup_segment, cvs_frag_to_fill): Only use if BFD_ASSEMBLER or + not BFD. + (merge_data_into_text): Only use if BFD_ASSEMBLER or (not BFD and + not OBJ_AOUT). + * write.h: Declare relax_segment. + * config/obj-coffbfd.c (stack_pop, stack_push, stack_init): Made + static. + (stack_top): Commented out, since it's not used. + Fixed up pseudo-op functions to take an ignored int argument. + (size_section): Added default BAD_CASE to switch. + Changed bzero calls to memset. + * config/obj-coffbfd.h (S_IS_LOCAL): Call strchr on S_GET_NAME + (s), not on s itself. + * config/tc-a29k.c (s_use): Take ignored int argument.
