From 2b47531bf9ef778773831ecb1b43186e95ffe8d7 Mon Sep 17 00:00:00 2001 From: Ian Lance Taylor Date: Thu, 3 Jun 1999 00:24:14 +0000 Subject: * app.c (input_buffer): New static variable. (app_push): Save saved_input in allocated buffer. (app_pop): Restored saved_input. (do_scrub_chars): Change get parameter to take char * and int as arguments. Change GET macro to pass input_buffer to get function. Don't save input into allocated buffer. * as.h (do_scrub_chars): Update declaration. * input-file.c (input_file_get): Change to take char * and int. Read data into passed in buffer. Remove static buffer. * read.c (scrub_from_string): Change to take char * and int. Copy data into passed in buffer. --- gas/read.c | 71 +++++++++++++++++++++++++++++++++++--------------------------- 1 file changed, 40 insertions(+), 31 deletions(-) (limited to 'gas/read.c') diff --git a/gas/read.c b/gas/read.c index abee749..7859fe1 100644 --- a/gas/read.c +++ b/gas/read.c @@ -208,7 +208,7 @@ static int dwarf_file_string; #endif static void cons_worker PARAMS ((int, int)); -static int scrub_from_string PARAMS ((char **)); +static int scrub_from_string PARAMS ((char *, int)); static void do_align PARAMS ((int, char *, int, int)); static void s_align PARAMS ((int, int)); static void s_lcomm_internal PARAMS ((int, int)); @@ -480,15 +480,18 @@ static char *scrub_string; static char *scrub_string_end; static int -scrub_from_string (from) - char **from; +scrub_from_string (buf, buflen) + char *buf; + int buflen; { - int size; - - *from = scrub_string; - size = scrub_string_end - scrub_string; - scrub_string = scrub_string_end; - return size; + int copy; + + copy = scrub_string_end - scrub_string; + if (copy > buflen) + copy = buflen; + memcpy (buf, scrub_string, copy); + scrub_string += copy; + return copy; } /* read_a_source_file() @@ -788,7 +791,7 @@ read_a_source_file (name) mri_pending_align = 0; if (line_label != NULL) { - line_label->sy_frag = frag_now; + symbol_set_frag (line_label, frag_now); S_SET_VALUE (line_label, frag_now_fix ()); } } @@ -869,7 +872,7 @@ read_a_source_file (name) mri_pending_align = 0; if (line_label != NULL) { - line_label->sy_frag = frag_now; + symbol_set_frag (line_label, frag_now); S_SET_VALUE (line_label, frag_now_fix ()); } } @@ -1489,10 +1492,12 @@ s_mri_common (small) if (line_label != NULL) { - line_label->sy_value.X_op = O_symbol; - line_label->sy_value.X_add_symbol = sym; - line_label->sy_value.X_add_number = S_GET_VALUE (sym); - line_label->sy_frag = &zero_address_frag; + expressionS exp; + exp.X_op = O_symbol; + exp.X_add_symbol = sym; + exp.X_add_number = 0; + symbol_set_value_expression (line_label, &exp); + symbol_set_frag (line_label, &zero_address_frag); S_SET_SEGMENT (line_label, expr_section); } @@ -2064,9 +2069,9 @@ s_lcomm_internal (needs_align, bytes_p) frag_align (align, 0, 0); /* detach from old frag */ if (S_GET_SEGMENT (symbolP) == bss_seg) - symbolP->sy_frag->fr_symbol = NULL; + symbol_get_frag (symbolP)->fr_symbol = NULL; - symbolP->sy_frag = frag_now; + symbol_set_frag (symbolP, frag_now); pfrag = frag_var (rs_org, 1, 1, (relax_substateT)0, symbolP, (offsetT) temp, (char *) 0); *pfrag = 0; @@ -2261,7 +2266,7 @@ s_macro (ignore) { S_SET_SEGMENT (line_label, undefined_section); S_SET_VALUE (line_label, 0); - line_label->sy_frag = &zero_address_frag; + symbol_set_frag (line_label, &zero_address_frag); } if (((flag_m68k_mri @@ -2783,9 +2788,12 @@ s_space (mult) S_SET_VALUE (mri_common_symbol, val + 1); if (line_label != NULL) { - know (line_label->sy_value.X_op == O_symbol); - know (line_label->sy_value.X_add_symbol == mri_common_symbol); - line_label->sy_value.X_add_number += 1; + expressionS *symexp; + + symexp = symbol_get_value_expression (line_label); + know (symexp->X_op == O_symbol); + know (symexp->X_add_symbol == mri_common_symbol); + symexp->X_add_number += 1; } } } @@ -2794,7 +2802,7 @@ s_space (mult) do_align (1, (char *) NULL, 0, 0); if (line_label != NULL) { - line_label->sy_frag = frag_now; + symbol_set_frag (line_label, frag_now); S_SET_VALUE (line_label, frag_now_fix ()); } } @@ -3114,7 +3122,8 @@ pseudo_set (symbolP) && (S_GET_SEGMENT (exp.X_add_symbol) == S_GET_SEGMENT (exp.X_op_symbol)) && SEG_NORMAL (S_GET_SEGMENT (exp.X_add_symbol)) - && exp.X_add_symbol->sy_frag == exp.X_op_symbol->sy_frag) + && (symbol_get_frag (exp.X_add_symbol) + == symbol_get_frag (exp.X_op_symbol))) { exp.X_op = O_constant; exp.X_add_number = (S_GET_VALUE (exp.X_add_symbol) @@ -3138,19 +3147,19 @@ pseudo_set (symbolP) #endif /* OBJ_AOUT or OBJ_BOUT */ S_SET_VALUE (symbolP, (valueT) exp.X_add_number); if (exp.X_op != O_constant) - symbolP->sy_frag = &zero_address_frag; + symbol_set_frag (symbolP, &zero_address_frag); break; case O_register: S_SET_SEGMENT (symbolP, reg_section); S_SET_VALUE (symbolP, (valueT) exp.X_add_number); - symbolP->sy_frag = &zero_address_frag; + symbol_set_frag (symbolP, &zero_address_frag); break; case O_symbol: if (S_GET_SEGMENT (exp.X_add_symbol) == undefined_section || exp.X_add_number != 0) - symbolP->sy_value = exp; + symbol_set_value_expression (symbolP, &exp); else { symbolS *s = exp.X_add_symbol; @@ -3164,7 +3173,7 @@ pseudo_set (symbolP) #endif /* OBJ_AOUT or OBJ_BOUT */ S_SET_VALUE (symbolP, exp.X_add_number + S_GET_VALUE (s)); - symbolP->sy_frag = s->sy_frag; + symbol_set_frag (symbolP, symbol_get_frag (s)); copy_symbol_attributes (symbolP, s); } break; @@ -3172,7 +3181,7 @@ pseudo_set (symbolP) default: /* The value is some complex expression.
