Previously this would turn off pc-rel calc + of displacement, while leaving pc-rel opcode alone, botching. + + * m68k.c (m68k_ip): Allow pc-relative effective addresses + for source operands. "pea" instructions are a good example + where we can shorten from abs long to pc+16bit. + (md_convert_frag): Fix "JBSR" comments to refer to "JSR", the + actual instruction. Insert comments about bug in 68000 bcc + and dbcc long code (that doesn't get exercised much). Add + comments about long pcrel displacements for -pic. Remove + "this code has not been tested" comment. + (md_estimate_size_before_relax): Now that fixup_segment + doesn't shortcircuit pc-relative fixups for undefined symbols, + only output them if -pic; else turn them absolute, which is + slightly faster. More JBSR->JSR comments. + (md_parse_options): Parse -pic. + +Fri Oct 19 14:35:20 1990 John Gilmore (gnu at cygint) + + * Make sparc assembler more compatible with Sun assembler. + sparc.c: reformat pseudo-op table to match main table. + (md_assemble): Add SPECIAL_CASE_FDIV to assemble FDIV* + instructions as fdiv followed by fmovs to get around chip bug. + (s_common, s_seg): Accept "bss" section name. + (md_assemble): Handle "set" instructions with absolute + operands, that only take one instruction rather than two. + sparc-opcode.h (fdiv*): Mark instructions "S"pecial. + subsegs.c (subseg_change): Move tail pointer too. + symbols.c (colon): Allow new definitions to override .comm symbols, + as in VMS. Sun CC depends on this. + write.c (new_fix): Always take r_type argument, not just on sparc. + Chain fixP's in order, using tail pointer, so relocation + records come out in forward order like Sun as. Remove SPARC + ifdefs. + write.h: Add seg_fix_tailP, data_fix_tailP, text_fix_tailP. + + * am29k.c: Use s_align_bytes rather than a local copy. + + * read.c (s_align): Rather than ifdef it, make two functions, + s_align_bytes and s_align_ptwo. Individual pseudo-op tables + can call whichever one they like. + + * write.c (append): Move from append.c to here. + append.c: Remove file. + + * Makefile (MDSRC, mdsrc): Easy way to edit all md.c's. + Fix options. Add option for -DDEBUG for know() and assert(). + Remove append.c, am29k.h. Don't build special read-sparc.o. + Remove sparc.h. "make clean" removes am29k .o's. Add + dependencies on reloc.h. + +Thu Oct 18 17:56:34 1990 John Gilmore (gnu at cygint) + + * Generalize sparc extensions to relocation info. Gas now + keeps relocation information internally in a different format + than how it is stored in the resulting .o. md_ri_to_bytes() + converts to external format. md_reloc_size says how large + each relocation record is in external format. + sparc.h: Remove this file. Rename to reloc.h. Rename struct + to reloc_info_generic. + reloc.h: Add relocation types for AMD 29000. + read.c, write.c: Always call fix_new with reloc-type argument. + write.c (emit_relocations): Make md_ri_to_bytes write directly + to output area rather than overwriting its argument then + bcopying it. + md.h: Declare md_reloc_size and md_ri_to_bytes. + i386.c, am29k.c, vax.c, ms32k.c, m68k.c, sparc.c: include reloc.h. + (md_reloc_size): Specify correct value. + (md_ri_to_bytes): Convert format from internal to external. + + write.c (write_object_file): Call md_section_align() which + rounds section sizes up if desired. + sparc.c (md_section_align): Round to 8 byte boundary. + i386.c, am29k.c, vax.c, ns32k.c, m68k.c (md_section_align): Nop. + +Mon Oct 15 22:06:11 1990 John Gilmore (gnu at cygint) + + Changes in support of the AMD 29000 version of gas. + + * am29k-opcode.h: Add dummy entry to end so we can examine + item N+1 without exceeding table. + + * am29k.h: New include file, derived from sparc.h. Kludged + together, still needs major work to get relocation working. + + * am29k.c: New file, derived from sparc.c. + Put 29k-specific ASM29K pseudo-ops into table. + Change comment_chars to ASM29K. + Change s_seg to s_use. + Change s_sparc_align to s_29k_align, default operand to 4. + (define_some_regs): Define special register names. + (md_begin): Preprocess opcode table to mash together all + the variants of single opcodes.

Don't start a new text + subsegment on each entry. Actually use the start and end + pointers returned by input_scrub_next_buffer. + (s_include): Call input_scrub_include_file for .include. + * input-scrub.c: Fix comments. + (struct input_save): Add, for saving state at .include. + (input_scrub_push, input_scrub_pop): Add, push & pop state. + (input_scrub_begin): Initialize next_saved_file. + (input_scrub_end): Free buffer. + (input_scrub_include_file): Add, to include a file. + (input_scrub_close): Add, to close a file. + (input_scrub_next_buffer): Set buffer-start address for + caller.

Avoid wiring character constants into app.c. + (do_scrub_begin): New meanings override old ones, not "OR" them. + Only handle /* comments if / is not already in use. + (do_scrub_next_char): Reorganize mass of nested if's + into a switch for speed. Don't assume ';' is line terminator. + Reorganize switch on characters, into a switch on their (machine- + dependent) lexer table meanings. + + + Encapsulate knowledge of segment types in fewer places. + This allows us to add the "SEG_REGISTER" type, as well as + providing flexibility for eventual COFF/ELF support. + * struc-symbol.h (symbol_to_segment, symbol_to_segment_type, + set_symbol_segment, set_symbol_segment_keep_ext, + segment_name): Define macros to encapsulate this info. + * as.h: Remove externs for seg_name, seg_N_TYPE, N_TYPE_seg. + * symbols.c (symbol_new): Change 'type' arg to 'seg'. + * expr.c, i386.c, m68k.c, ns32k.c, read.c, symbols.c, vax.c, + write.c: Use macros. + * i386.c, m68k.c, ns32k.c, vax.c, write.c: Change 2nd arg type of + md_estimate_size_before_relax. + * expr.c, read.c: Change 'type' arg to symbol_new. + * read.c, symbols.c, vax.c, write.c: Move md.h to end of includes. + + + Allow expressions to evaluate to registers. + * as.h: Add SEG_REGISTER. + * struc-symbol.h: Add fake N_REGISTER type. + * subseg.c: Add types to tables. + * expr.c (operand): Symbols of SEG_REGISTER type are + immediately evaluated like those of SEG_ABSOLUTE. + (clean_up_expression): Clean up SEG_REGISTER exprs. + + + Allow machine descriptions to cleanly extend the set of + possible operands. + * expr.c (operand): Call md_operand before rejecting an + operand as unacceptable. + * md.h: declare. + * i386.c, ns32k.c, m68k.c, sparc.c, vax.c: Define null function. + * am29k.c (md_operand): Use this for %% and & prefix operators. + + + Allow machine descriptions to cleanly permit symbols to be + predefined upon first usage. + * symbols.c (symbol_find_or_make): Call md_undefined_symbol + before making an undefined symbol. + * md.h: declare. + * i386.c, ns32k.c, m68k.c, sparc.c, vax.c: Define null function. + * am29k.c (md_undefined_symbol): use this for the local and + global register names; since there are hundreds of them, it + only defines them upon their first use. + * expr.c (operand): Call symbol_find_or_make rather than + roll our own undefined symbols. + + + Miscellaneous changes: + + * as.h (know): Make this useful if DEBUG defined. + + * write.h: Support SPARC-like relocation throughout all + versions. + + * read.c (read_a_source_file): Report the name of invalid + pseudo-ops.

So far, they are just stubbed out. + + * read.c (pobegin): Allow the machine dependent pseudo-op + table to override the generic one. Remove #ifdef SPARC + on .word, since it can now be overridden. + + * expr.c (operand): Support radix-2 constants. Kill off + support for octals with digits '8' and '9'.
