From 3098ca6d164fe88826fc2b24fc0b7dadc69f1851 Mon Sep 17 00:00:00 2001 From: Alan Modra Date: Wed, 3 May 2006 23:52:15 +0000 Subject: * subsegs.h (struct frchain): Delete frch_seg. (frchain_root): Delete. (seg_info): Define as macro. * subsegs.c (frchain_root): Delete. (abs_seg_info, und_seg_info, absolute_frchain): Delete. (subsegs_begin, subseg_change): Adjust for above. (subseg_set_rest): Likewise. Add new frchain structs to seginfo rather than to one big list. (subseg_get): Don't special case abs, und sections. (subseg_new, subseg_force_new): Don't set frchainP here. (seg_info): Delete. (subsegs_print_statistics): Adjust frag chain control list traversal. * debug.c (dmp_frags): Likewise. * dwarf2dbg.c (first_frag_for_seg): Don't start looking for frag at frchain_root. Make use of known frchain ordering. (last_frag_for_seg): Likewise. (get_frag_fix): Likewise. Add seg param. (process_entries, out_debug_aranges): Adjust get_frag_fix calls. * write.c (chain_frchains_together_1): Adjust for struct frchain. (SUB_SEGMENT_ALIGN): Likewise. (subsegs_finish): Adjust frchain list traversal. * config/tc-xtensa.c (xtensa_cleanup_align_frags): Likewise. (xtensa_fix_target_frags, xtensa_mark_narrow_branches): Likewise. (xtensa_mark_zcl_first_insns, xtensa_fix_a0_b_retw_frags): Likewise. (xtensa_fix_b_j_loop_end_frags): Likewise. (xtensa_fix_close_loop_end_frags): Likewise. (xtensa_fix_short_loop_frags, xtensa_sanity_check): Likewise. (retrieve_segment_info): Delete frch_seg initialisation. --- gas/dwarf2dbg.c | 29 ++++++++++------------------- 1 file changed, 10 insertions(+), 19 deletions(-) (limited to 'gas/dwarf2dbg.c') diff --git a/gas/dwarf2dbg.c b/gas/dwarf2dbg.c index 16666fa4f2..661962ff20 100644 --- a/gas/dwarf2dbg.c +++ b/gas/dwarf2dbg.c @@ -169,7 +169,7 @@ static void out_two (int); static void out_four (int); static void out_abbrev (int, int); static void out_uleb128 (addressT); -static offsetT get_frag_fix (fragS *); +static offsetT get_frag_fix (fragS *, segT); static void out_set_addr (symbolS *); static int size_inc_line_addr (int, addressT); static void emit_inc_line_addr (int, addressT, char *, int); @@ -670,27 +670,18 @@ dwarf2_directive_loc_mark_labels (int dummy ATTRIBUTE_UNUSED) static struct frag * first_frag_for_seg (segT seg) { - frchainS *f, *first = NULL; - - for (f = frchain_root; f; f = f->frch_next) - if (f->frch_seg == seg - && (! first || first->frch_subseg > f->frch_subseg)) - first = f; - - return first ? first->frch_root : NULL; + return seg_info (seg)->frchainP->frch_root; } static struct frag * last_frag_for_seg (segT seg) { - frchainS *f, *last = NULL; + frchainS *f = seg_info (seg)->frchainP; - for (f = frchain_root; f; f = f->frch_next) - if (f->frch_seg == seg - && (! last || last->frch_subseg < f->frch_subseg)) - last= f; + while (f->frch_next != NULL) + f = f->frch_next; - return last ? last->frch_last : NULL; + return f->frch_last; } /* Emit a single byte into the current segment. */ @@ -745,7 +736,7 @@ out_abbrev (int name, int form) /* Get the size of a fragment. */ static offsetT -get_frag_fix (fragS *frag) +get_frag_fix (fragS *frag, segT seg) { frchainS *fr; @@ -755,7 +746,7 @@ get_frag_fix (fragS *frag) /* If a fragment is the last in the chain, special measures must be taken to find its size before relaxation, since it may be pending on some subsegment chain. */ - for (fr = frchain_root; fr; fr = fr->frch_next) + for (fr = seg_info (seg)->frchainP; fr; fr = fr->frch_next) if (fr->frch_last == frag) return (char *) obstack_next_free (&fr->frch_obstack) - frag->fr_literal; @@ -1134,7 +1125,7 @@ process_entries (segT seg, struct line_entry *e) /* Emit a DW_LNE_end_sequence for the end of the section. */ frag = last_frag_for_seg (seg); - frag_ofs = get_frag_fix (frag); + frag_ofs = get_frag_fix (frag, seg); if (frag == last_frag) out_inc_line_addr (INT_MAX, frag_ofs - last_frag_ofs); else @@ -1332,7 +1323,7 @@ out_debug_aranges (segT aranges_seg, segT info_seg) s->text_start = beg; frag = last_frag_for_seg (s->seg); - end = symbol_temp_new (s->seg, get_frag_fix (frag), frag); + end = symbol_temp_new (s->seg, get_frag_fix (frag, s->seg), frag); s->text_end = end; expr.X_op = O_symbol; -- cgit v1.2.1
