(Can happen for certain invalid input.) * c-typeck.c (build_modify_expr): Block path that made a MODIFY_EXPR containing an ERROR_MARK. * config/tm.h: New file. * loop.c (only_reg_use_p): Fix bugs in recursion, add some fast special cases. Comment on return value was backwards. (strength_reduce): Negate the value of only_reg_use_p. * genoutput.c (output_prologue): Output `#include hard-reg-set.h'. * Makefile: insn-output.o depends on that. * toplev.c (main): Typo recognizing -Wswitch. * config.gcc (mips): New alternative. * tm-mips.h, out-mips.c, mips.md, va-mips.h: New files. * varargs.h: Include va-mips.h if on mips. Wed Apr 5 16:58:04 1989 Richard Stallman (rms at sugar-bombs.ai.mit.edu) * c-decl.c (duplicate_decls): Rename OLD, NEW to OLDDECL, NEWDECL. * stmt.c (expand_function_start): Ref subr instead of current_function_decl; should make no difference. * stmt.c (assign_parms): Do extra padding for some parms, controlled by MAX_PARM_BOUNDARY. * expr.c (expand_call): Same thing for caller side. Note this is implemented only for machines that lack push insns. Also, in both cases, it doesn't handle variable-size args. Tue Apr 4 12:22:06 1989 Richard Stallman (rms at sugar-bombs.ai.mit.edu) * gcc.c (find_file): Try STANDARD_EXEC_PREFIX for startfiles too. * varasm.c (make_decl_rtl): Delete never-executed clause. * spur.md (movqi, loadhi, extend*, zero_extendhisi): Make subregs with C code, not RTL patterns, so we can avoid generating subreg of subreg. * optabs.c (emit_cmp_insn): Not all clauses always succeed, so stop using `else' structure. * stmt.c (expand_return): Avoid moving void to void, in cleanups case. Mon Apr 3 18:04:33 1989 Richard Stallman (rms at sugar-bombs.ai.mit.edu) * m68k.md (cmphi): Don't allow a-reg vs a-reg, since that sign-extends. If there is one a-reg, make sure it is not last. Sun Apr 2 13:02:26 1989 Richard Stallman (rms at sugar-bombs.ai.mit.edu) * stor-layout.c (agg_mode): Use highest mode that has desired size. Allow all integer modes, but reject sizes > MAX_FIXED_MODE_SIZE. (That defaults to the size of DImode.) * machmode.def: Add PSI, PDI and XF, CXF modes. Sat Apr 1 00:50:11 1989 Richard Stallman (rms at sugar-bombs.ai.mit.edu) * ns32k.md (ashd, lshd): Delete patterns that logand the count with 31. The shift count is not truncated on this machine. * combine.c (subst): Simplify nested or's, nested xor's. (try_distrib): XOR doesn't distribute through anything. * rtl.c (rtx_equal_p): Don't die on null pointers. * loop.c (eliminate_biv): Use COMPARE, not MINUS, in generated compare. * loop.c (invariant_p): Mem refs in constant pool are invariant. * c-decl.c (redeclaration_error_message): If -traditional, allow redeclarations of typedef provided they agree. * c-decl.c (start_decl): Do expand_decl on the decl that pushdecl returns. If there was a prev. decl with a different type, we have changed its type and cleared its old rtl, so it need new rtl. Sat Apr 1 00:50:11 1989 Matthew Self (rms at sugar-bombs.ai.mit.edu) * expr.c (convert_move): Modified to use mode classes instead of refering to specific machine modes. * expr.c (do_jump): Converted to use CONST0_RTX macro. do_jmp no longer refers to any machine modes directly except for VOIDmode! * expr.c (compare, compare1): Modified to use CONST0_RTX macro. No longer refers to any machine modes directly except VOIDmode and BLKmode! * machmode.def: Documented assumptions made about the order of machine modes during mode widening. * optabs.c (expand_binop, expand_twoval_binop, expand_unop, emit_cmp_insn): Added mode widening which is independent of specific machine modes. It assumes that we may widen to any higher numbered mode of the same mode class. NOTE: the checks for VOIDmode ops which were present in QI and HI to SI widening are now present in all widening. I assume this is correct. Also, widening is now possible from QI to HI. This may or may not be a good thing.... * rtl.h (CONST0_RTX): Added definition of new macro CONST0_RTX (mode). * rtl.h (GET_NOTE_INSN_NAME, GET_REG_NOTE_NAME): New macros. * rtl.c (note_insn_name, reg_note_name): New tables. * rtl.def (NOTE): Change last field from `i' to `n'. * rtl.c (print_rtx): Print mode of INSN_LIST or EXPR_LIST as reg-note. Print operand code `n' as name of kind of note. (read_rtx): treat `n' like `i'. * loop.c (struct induction): Add `mode' field. (strength_reduce, record_giv): Set the `mode' field in V. (can_eliminate_biv_p, eliminate_biv): Use that field. * loop.c (struct iv_class): `init_insn' records what inits the biv. Replaces `init_val_set' flag. (strength_reduce): Update and test `init_insn' instead. Use of a biv between its init and the start of the loop does not preclude its elimination from the loop. Setting a giv is ok for eliminating a biv, even if giv is "ignore", since that just means giv will be combined with another. Handle some DEST_ADDR givs for that purpose. Test for giv-setting before check can_eliminate_biv_p. New error check for replaceable giv whose value needed after loop. (only_reg_use_p): New fn. * expr.c (expand_expr): PLUS, MINUS with EXPAND_SUM: Associate even harder. * loop.c (strength_reduce): Treat all constant biv init vals like ints. * loop.c (strength_reduce): Clear all_reduced when v->ignore is set; the code to check this later didn't always do the job. * loop.c (verify_loop): Set loop_continue. (scan_loop): mention its value. * rtl.h: Define NOTE_INSN_LOOP_CONT. * stmt.c (expand_loop_continue_here): Output one. Fri Mar 31 10:08:29 1989 Richard Stallman (rms at sugar-bombs.ai.mit.edu) * c-typeck.c (pointer_int_sum, pointer_diff): Treat const void * like void *. * rtl.c (rtx_addr_varies_p): Don't die on null exp. * cse.c (refers_to_mem_p, refers_to_p): Likewise. * gcc.c (validate_switches, validate_all_switches): New fns. Mark a switch as valid if any compiler spec or the linker spec matches it, even for languages not being used. Thu Mar 30 00:22:14 1989 Richard Stallman (rms at sugar-bombs.ai.mit.edu) * loop.c (loop_optimize, move_movables): when moving a `clr' insn used in zero-extension, sometimes change it to an `and' so that the significant low bits are not clobbered. * cccp.c: Implement __BASE_FILE__ and #once. (savestring): New fn. (struct file_name_list): new name for struct directory_stack. (enum node_type): Add T_ONCE, T_BASE_FILE. (directive_table): Add #pragma once.

(do_once): New fn; add current file to #pragma once list. * cccp.c (do_include): Don't add non-ex files to list of deps. * config.gcc: Use {...:-...}, not {...=...}. * c-parse.y: Add precedence for IF/ELSE, and for parens; avoids some conflicts. * tm-newsgas.h: Include tm-news.h and define USE_GAS. * tm-news.h: New name for tm-news800.h.

(ASM_IDENTIFY_GCC): Override; output nothing. (FUNCTION_PROLOGUE, FUNCTION_EPILOGUE): Round fsize up to % 4. Max for halfword link insn is 32k, not 64k. (FUNCTION_EPILOGUE): Don't output move.l if no regs to restore. (PRINT_OPERAND_ADDRESS): Change handling of tableref pc-rel addresses. * m68k.md (movhi): Add SONY_ASM conditional. * cse.c (cse_insn): If replacing a dest address, preserve MEM_IN_STRUCT * gcc.c (error, fatal): alternate varargs defns if HAVE_VPRINTF. Wed Mar 29 09:54:13 1989 Richard Stallman (rms at sugar-bombs.ai.mit.edu) * gcc.c (process_command): Check WORD_SWITCH_TAKES_ARG, so that -Tdata can be handled right. * stmt.c (check_for_full_enumeration_handling): new fn, for warn_switch (expand_end_case): Call it, if orig index was enum. * toplev.c (main): Handle -Wswitch. * c-parse.y (SWITCH stmt): Pass orig switch expr to expand_end_case. * tm-*.h, out-*.c: Uniformly use reg_names, not reg_name, and don't define any duplicates. * final.c: Delete reg_name. * c-parse.y (is_reserved_word): Add keywords __asm and __inline; also __const and __volatile. (yylex): Keywords that start with `__' are recognized regardless of -traditional or -ansi. * c-parse.y (check_newline): Always recognize #ident. Macro IDENT_DIRECTIVE is no more.

Eliminate confusion; do only one change between tests for PLUSness. (output_move_double): Arg to find_addr_reg is address, not mem ref. * out-m68k.c, out-spur.c, out-i386.c, out-alliant.c: Likewise. * jump.c (find_cross_jump): Don't let either E1 or E2 be included in the range of matching insns preceding the other (E2 or E1). * c-parse.y (check_newline): No error for `#pragma\n'. * Makefile (gcc.o): Control STANDARD_STARTFILE_PREFIX here. * stmt.c (walk_fixup_memory_subreg): handle null. * tm-sparc.h (FUNCTION_BLOCK_PROFILER): Change LPBnn to LPYnn, to avoid conflict with final.c.

(expand_function_start): Compute return_label after testing that. (expand_function_end): Output a return insn after pcc-struct-return processing, if there is a return insn. (expand_null_return): Don't output a return insn, in that case. Simplify the conditions--depends entirely on HAVE_return. * tm-m68k.h (FUNCTION_BLOCK_PROFILER): Use jsr, not call. * reload.c (find_reloads): Certain mem addresses will be offsetable after reloading; in particular, those where reg_equiv_address applies. * loop.c (check_dbra_loop): Change MINUS to COMPARE. * c-typeck.c (convert_for_assignment): Return THE standard error_mark.

Thu Jan 19 13:53:24 1989 Richard Stallman (rms at sugar-bombs.ai.mit.edu) * c-typeck.c (mark_addressable): For global reg var, report error. Now returns an int; value of 0 means caller should fail. All calls (in this file) changed. * stor-layout.c (layout_decl): Don't let an more than 1 word of any aggregate go in any 1 register. (Needed for machines whose integer regs are 64 bits). * tm-convex.h, xm-convex.h, convex.md, output-convex.c: new files. * expr.c (convert_move): Use extendqidi2, etc. for converting small ints to double ints.

No need to test INSN1 for being a label, since not called then. [If any of the matched insns is a JUMP_INSN, set want_jump, and in that case make the matched peephole a JUMP_INSN itself.] That's in an #if 0 now; it's good in jump, but not in final. * jump.c (jump_optimize): Don't do peepholes here. * final.c (final): Do them here. * jump.c (jump_optimize): In optimizing `if (foo) bar; else break;', don't try to invert anything but a standard-looking conditional jump. * jump.c (jump_optimize): Do peepholes on ALL BUT the first pass. * gcc.c (env_exec_prefix): New var used like user_exec_prefix but set from envvar GCC_EXEC_PREFIX.

Distinguisn missing asm from invalid name. * expr.c (expand_call): Never return 0; return const0_rtx instead. This makes expand_expr more uniform. * c-decl.c (grokparms): For ptr to incomplete type, just warn; don't change the parm's type. * stmt.c (expand_return): Set RETVAL_RHS so as to recognize tail-recursive fcn returning void. Unconditionally test value of expand_expr for being a REG. * reload.c (find_reloads): Don't process insns that have no constraint alternatives.

(output_epilogue, scan_operands): Errors in input are not fatal. * flow.c (regno_uninitialized): Avoid crash if no basic blocks. * sparc.md (move insns): Delete special patterns that handled symbolic constant addresses. The main move patterns now do this. * output-sparc.c (output_store, output_load_{fixed,floating}): Subroutines to do the work for this; has the code from those special patterns. Also fixed bugs in testing against cc_status.mdep. * output-sparc.c (output_delay_insn): Clear the CC status. This is necessary for %g1 in the case of a call insn. * tm-i386.h (REG_CLASS_CONTENTS): INDEX_REGS is now all but ESP. (REGNO_REG_CLASS): Corresponding change. (REG_CLASS_FROM_LETTER): Eliminate `x' letter since not used. * optabs.c (emit_cmp_insn): New arg ALIGN, used for BLKmode. All callers changed.
