From: Ken Raeburn Date: Fri, 3 Dec 1993 03:10:08 +0000 (+0000) Subject: Lots of changes for: X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=bfbfba45ba4180bae6e737c9c9c7c120262a07a7;p=deliverable%2Fbinutils-gdb.git Lots of changes for: - sparc[lite]-coff as well as sparc-lynx - producing coff (including debug info) under BFD_ASSEMBLER option - cleanup of cpu-specific code in non-cpu-specific files (especially write.c) - providing common code to avoid duplication in cpu-specific files (specifically, md_number_to_chars) - stylistic changes & misc cleanup ================ * config/tc-sparc.c (tc_gen_reloc): Make adjustment to addend be dependent on howto fields, not on format flavour. * struc-symbol.h (struct symbol): New fields sy_obj and sy_tc, defined as types OBJ_SYMFIELD_TYPE and TC_SYMFIELD_TYPE, if those macros are defined. * config/obj-coff.h (TC_SYMFIELD_TYPE, OBJ_SYMFIELD_TYPE): Define. (TARGET_SYMBOL_FIELDS, I960_SYM_FIELDS): Don't define. (sy_tc, sy_obj): Define so that the fields look like they used to, until all references get changed. * write.c (fixup_segment): Lots of variables no longer register. Reordered some code for easier reading. * config/obj-coff.c (obj_coff_dim): dim_index no longer register. Deleted superfluous return statement. (obj_coff_line, obj_coff_size, obj_coff_scl, obj_coff_type, obj_coff_val, tag_init, tag_insert): Deleted superfluous return statement. (align, obj_coff_section): Deleted debugging printfs. * config/tc-i386.c (md_assemble): Discard some register decls. Use assignment rather than memcpy to copy template. (op_hash, reg_hash, prefix_hash): Default C initialization of statics is sufficient. * config/tc-sparc.c (print_insn): Array Reloc is now const, and points to const. * config/obj-coff.h (TARGET_FORMAT): Only use coff-sparc-lynx if TE_LYNX; use coff-sparc otherwise. [USE_NATIVE_HEADERS]: Delete this code; it isn't used. * write.c (fixup_segment): Call TC_VALIDATE_FIX, if defined, before processing a fixup. Call TC_ADJUST_RELOC_COUNT just before returning. Remove some i960-coff-specific code. (TC_ADJUST_RELOC_COUNT): Default to doing nothing. * config/tc-i960.h (TC_ADJUST_RELOC_COUNT) [OBJ_COFF]: Define. (i960_validate_fix): Declare. (TC_VALIDATE_FIX): Define. * config/tc-i960.c (i960_validate_fix): New function. * write.c (number_to_chars_littleendian): New function. Write out bytes in little endian order, doing size and range checking. (number_to_chars_bigendian): New function, similar. * write.h: Declare them. * config/tc-*.c (md_number_to_chars): Use them. * config/tc-vax.c (md_apply_fix): Ditto. * config/tc-i386.c (md_apply_fix): Ditto. * config/obj-coff.c: Rearranged code for handling line number data. (line_fsym): Renamed from function_lineoff in BFD_ASSEMBLER case, since the usage is different from non-BFD_ASSEMBLER case. (in_function, clear_function, set_function): New macros, to combine some of the functionality implemented in differnet ways in BFD_ASSEMBLER and non-... code. Used in other functions that used to check function_lineoff &c. (obj_emit_lineno): Split into two copies, one for BFD_ASSEMBLER, one for not. Non-BFD_ASSEMBLER version now has temporary variable to contain char* pointer pointed to by char** argument. Always follow CROSS_COMPILE code; easier to read that way. (obj_coff_ln): Don't call add_lineno or c_line_new if appline is set. (obj_coff_endef) [BFD_ASSEMBLER]: Don't do anything special for ".bf", it's been done elsewhere. (coff_frob_symbol): If ilne number data is pending, call add_linesym to flush it. (coff_frob_file): Don't do that here. * config/obj-coff.h (coff_frob_file): Declare. (obj_frob_file): Define, to call it. * config/tc-sparc.h (md_create_short_jump, md_create_long_jump, md_estimate_size_before_relax: Define them as macros calling as_fatal. * config/tc-sparc.c: Don't define them as functions. --- diff --git a/gas/.Sanitize b/gas/.Sanitize index 7919817c4b..8442ebf819 100644 --- a/gas/.Sanitize +++ b/gas/.Sanitize @@ -124,7 +124,86 @@ fi # # # $Log$ -# Revision 1.22 1993/11/22 06:04:32 law +# Revision 1.23 1993/12/03 03:06:48 raeburn +# Lots of changes for: +# - sparc[lite]-coff as well as sparc-lynx +# - producing coff (including debug info) under BFD_ASSEMBLER option +# - cleanup of cpu-specific code in non-cpu-specific files +# (especially write.c) +# - providing common code to avoid duplication in cpu-specific files +# (specifically, md_number_to_chars) +# - stylistic changes & misc cleanup +# +# ================ +# +# * config/tc-sparc.c (tc_gen_reloc): Make adjustment to addend be dependent on +# howto fields, not on format flavour. +# +# * struc-symbol.h (struct symbol): New fields sy_obj and sy_tc, defined as types +# OBJ_SYMFIELD_TYPE and TC_SYMFIELD_TYPE, if those macros are defined. +# * config/obj-coff.h (TC_SYMFIELD_TYPE, OBJ_SYMFIELD_TYPE): Define. +# (TARGET_SYMBOL_FIELDS, I960_SYM_FIELDS): Don't define. +# (sy_tc, sy_obj): Define so that the fields look like they used to, until all +# references get changed. +# +# * write.c (fixup_segment): Lots of variables no longer register.
