From fca59f9d42e32d441760c1c0e182dcd98fbee7f0 Mon Sep 17 00:00:00 2001 From: Jeff Law Date: Thu, 13 Jan 1994 06:06:35 +0000 Subject: [PATCH] * config/tc-hppa.c (hppa_fix_struct): Add new "segment" field. (hppa_fix_new): Initialize segment field. (md_apply_fix): Do nothing for pc-relative fixup which involves crossing a segment boundary. (pa_procend): Undefine the current label after handling .PROC and .PROCEND directives. (dummy_symbol): Make type "symbolS *". Change references as appropriate. --- gas/config/tc-hppa.c | 22 +++++++++++++++++----- 1 file changed, 17 insertions(+), 5 deletions(-) diff --git a/gas/config/tc-hppa.c b/gas/config/tc-hppa.c index 5005bbd786e..b070ae245ac 100644 --- a/gas/config/tc-hppa.c +++ b/gas/config/tc-hppa.c @@ -422,6 +422,9 @@ struct hppa_fix_struct /* The unwind descriptor associated with this fixup. */ char fx_unwind[8]; + + /* The segment this fixup appears in. */ + segT segment; }; /* Structure to hold information about predefined registers. */ @@ -724,7 +727,7 @@ static label_symbol_struct *label_symbols_rootp = NULL; static int hppa_field_selector; /* A dummy bfd symbol so that all relocations have symbols of some kind. */ -static asymbol *dummy_symbol; +static symbolS *dummy_symbol; /* Nonzero if errors are to be printed. */ static int print_errors = 1; @@ -1211,6 +1214,7 @@ fix_new_hppa (frag, where, size, add_symbol, offset, exp, pcrel, hppa_fix->fx_r_field = r_field; hppa_fix->fx_r_format = r_format; hppa_fix->fx_arg_reloc = arg_reloc; + hppa_fix->segment = now_seg; if (unwind_desc) { bcopy (unwind_desc, hppa_fix->fx_unwind, 8); @@ -1329,7 +1333,7 @@ md_begin () subseg_set (text_section, 0); dummy_symbol = symbol_find_or_make ("L$dummy"); - dummy_symbol->section = text_section; + S_SET_SEGMENT (dummy_symbol, text_section); } /* Assemble a single instruction storing it into a frag. */ @@ -2739,7 +2743,7 @@ tc_gen_reloc (section, fixp) case R_LSEL: case R_RSEL: /* There is no symbol or addend associated with these fixups. */ - relocs[i]->sym_ptr_ptr = dummy_symbol; + relocs[i]->sym_ptr_ptr = &dummy_symbol->bsym; relocs[i]->addend = 0; break; @@ -2904,10 +2908,17 @@ md_apply_fix (fixP, valp) fixP->fx_addnumber = val; /* Check if this is an undefined symbol.
