(FUNCTION_VALUE, FUNCTION_ARG, LIBCALL_VALUE): Use integer registers
for FP items if -mno-fp-regs.
* alpha.c (alpha_builtin_saveregs): Store integer regs twice instead
of storing the FP regs if -mno-fp-regs.
* fold-const.c (fold): Add missing test in case when we
distribute a NOP_EXPR into a COND_EXPR and try to pull it back
out again.
Thu Oct 15 08:11:00 1992 Tom Wood (wood@dg-rtp.dg.com)
* fold-const.c (simple_operand_p): Don't regard global or static
variables as simple.
(fold_truthop): Only require the RHS to be simple.
* m88k.h (CPP_SPEC): Add -D__m88110__ when -m88110 is in effect,
similarly for -m88100.
* m88kdgux.h (CPP_SPEC): Ditto.
* m88kluna.h (CPP_PREDEFINES): Drop -Dmc88100.
(CPP_SPEC): Reproduce the predefine -Dmc88100 when -m88100 is in
effect. Otherwise, supply -D__mc881x0__ when -m881x0 is in effect.
Thu Oct 15 02:09:49 1992 Richard Stallman (rms@mole.gnu.ai.mit.edu)
* expr.c (get_inner_reference):
If flag_volatile, treat every INDIRECT_REF as volatile.
* collect2.c (main): If COLLECT_GCC is a relative name, use it anyway.
* x-next: New file.
* configure (m68k-next-*): Use that.
* Changes from NeXT:
* libgcc2.c [L_ctors] (__CTOR_LIST__, __DTOR_LIST__):
Initialize these default definitions if __NeXT__.
* gvarargs.h [__NeXT__]: Define _VA_LIST_ if _ANSI_STDARG_H_ was
defined; then define _ANSI_STDARG_H_.
* gstddef.h (_ANSI_STDDEF_H): Define, along with _STDDEF_H.
* next.h (INCLUDE_DEFAULTS): New macro.
* cp-method.c (index, rindex): Delete declarations.
(build_overload_value): Cast result of index.
* cccp.c (cplusplus_comments): New var.
(main): Set it according to options.
(rescan, handle_directive, skip_if_group, validate_else):
(skip_to_end_of_comment, macarg1, discard_comments):
Use cplusplus_comments to enable C++ comment syntax.
Wed Oct 14 11:34:58 1992 Chip Salzenberg (chip@tct.com)
* libgcc2.c (__gcc_bcmp): Don't depend on signedness of `char'.
Wed Oct 14 18:52:28 1992 Jim Wilson (wilson@wookumz.gnu.ai.mit.edu)
* sched.c (sched_note_set): Set subreg_p for anything except a
paradoxical subreg.
* configure (sparc-*-solaris2): Use xm-spc-sol2.h not xm-spcv4.h.
* reload.c (find_reloads): Don't let an operand have a numbered
constraint that makes it match itself.
Wed Oct 14 10:38:31 1992 Tim Moore (moore@defmacro.cs.utah.edu)
* pa.md (sCC patterns): Comparison operator should have SImode,
not CCmode.
(indexed addressing mode patterns): New patterns to use indexed
addressing if possible.
* pa.c (output_and): Do handle (const_int 0) as an operand; it
seems to occur in unoptimized compilation.
* pa.h (REGNO_OK_FOR_FP_P): Logic bug.
* va-pa.h : When __GNUC__ == 1, don't include the gcc 1 varargs
file (va-hp9k8.h). Instead, the definitions are explicitly defined
here. This avoids multiple typedefs of va_list.
* xm-pa.h (HAVE_VPRINTF) Define in HPUX 8.0.
* pa.md (mulsi): Use the hardware multiply instruction, xmpyu, if
TARGET_SNAKE.
(umulsidi3): New pattern.
(reload_insi, reload_outsi, reload_indi, reload_outdi): New
patterns. These are needed because SImode and DImode pseudoregs
may be allocated (or reloaded) in floating point registers for
multiplication. That means that their addresses, which were
legitimate for SImode and DImode, aren't valid any more.
(movsi, movhi, movqi, movdf, movdi, movsf): Pass null scratch
operand to emit_move_sequence.
(fp SImode load and store patterns): Move before main movsi
pattern.
(fp DImode load and store patterns) New patterns.
(movhi, movqi patterns): Support moves to/from fp registers.
(movdf pattern): Ensure at least one operand is a register.
* pa.c (emit_move_sequence): Take reload scratch register
argument, deal with reloads of SImode and DImode mems into
floating point registers, handle function_label_operand moves.
(secondary_reload_class): A scratch register is needed if
reloading a function_label_operand address (probably doesn't
happen) or an SImode or DImode value into/out of a floating
point register.
* pa.h (reg_class, REG_CLASS_NAMES, REG_CLASS_CONTENTS,
REG_CLASS_FROM_LETTER): Define a new register class
FP_OR_SNAKE_FP_REGS, used only be reload_{in,out}{si,di}.
(HARD_REGNO_MODE_OK): Allow all integer modes in Snake floating
point registers. QImode and HImode pseudoregs may end up there
when using xmpyu.
* pa.md (pic symbolic address pattern): New pattern.
(movsi, movdi patterns): Remove some * constraints from fp registers.
(pic label address pattern): Fix typo.
(function_label_operand patterns): New patterns for loading a
label address in HPUX 8.0.
* pa.c (finalize_pic): No real initialization is necessary for pic.
(output_function_prologue): Save r19, the pic offset table
register. If profiling, save and restore the structure value
return register (r28) around the call to mcount.
(hppa_encode_label, function_label_operand): New functions.
Record if a label is a code label so it can be treated specially
in HPUX 8.0.
* pa.h (TARGET_SHARED_LIBS): New flag. Generate code that can be
linked with HPUX 8.0 shared libraries.
(TARGET_SWITCHES): New flags: -mshared-libs and -mno-shared-libs.
(PIC_OFFSET_TABLE_REGNUM): This is really r19. The preliminary
docs from HP were wrong.
(ASM_DECLARE_FUNCTION_NAME): Specify "ENTRY" param in .EXPORT
directive.
(ENCODE_SECTION_INFO): Encode function labels.
(ASM_OUTPUT_LABELREF): Deal with function labels.
(ASM_OUTPUT_REG_PUSH, ASM_OUTPUT_REG_POP): Don't do anything for
now; their only use (saving stuff during profiling) interacts in a
wierd way with required assembler directives at the start of a
function. Instead, do the save and restore in the function
prologue.
(hppa_encode_label): Declare.
* pa-hpux.h, pa-ghpux.h (TARGET_DEFAULT): Link against shared
libraries.
(LINK_SPEC): Don't link against shared libraries if debugging or
profiling.
* pa1-hpux.h, pa1-ghpux,h (TARGET_DEFAULT): Link against shared
libraries.
Wed Oct 14 10:17:49 1992 Richard Stallman (rms@mole.gnu.ai.mit.edu)
* Makefile.in (gcc.xtar): Copy the objc subdir.
(mostlyclean): Run the mostlyclean target in the objc subdir.
(objc-runtime, libobjc.a, sublibobjc.a): New targets.
(objc, objective-c): Dep on objc-runtime.
* objc/*: New files.
Wed Oct 14 07:17:19 1992 Richard Kenner (kenner@vlsi1.ultra.nyu.edu)
* alpha.md (smax, smin): Fix typo in output strings.
* a29k.c (const_16_operand, const_24_operand): Fix typo in declaration
of MODE.
(gpc_reg_or_immediate_operand, and_operand, add_operand): Likwise.
Wed Oct 14 00:12:16 1992 Jeffrey A. Law (law@schirf.cs.utah.edu)
* pa.h (RTX_COST): Fix spacing typo.
Tue Oct 13 21:51:05 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
* a29k.md (call, call_value): Don't use call_operand, since
checking for recursive calls at this point is not safe.
Tue Oct 13 18:52:17 1992 Brendan Kehoe (brendan@rtl.cygnus.com)
* cp-type2.c (my_friendly_abort): Tell them to write to bug-g++.
Tue Oct 13 18:16:12 1992 Chris Smith (csmith@convex.com)
* convex.h (P_tmpdir): define to use /tmp.
(RETURN_POPS_ARGS): correct definition to return size.
(ASM_IDENTIFY_GCC): output something between gcc2_compiled and
first function to keep gcc2_compiled out of assembler stabs.
* convex.md (adddi3, ordi3, xordi3): check sign of CONST_INT
operands before using as immediates; these insns are word only.
(ashrdi3): don't use negative shift counts.
* convex*.h (CPP_SPEC): define __NO_INLINE_STDLIB
* xm-convex.h: remove temporary workaround from OS 8.0.
Tue Oct 13 14:10:15 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
* cp-lex.c (check_newline): Verify that main_input_filename is
valid before using it.
Tue Oct 13 19:08:54 1992 Richard Kenner (kenner@vlsi1.ultra.nyu.edu)
* a29k.c: Now includes reload.h.
(spec_reg_operand): Validate mode and know that some regs support
MODE_PARTIAL_INT and some MODE_INT.
(call_operand, reload_memory_operand, a29k_get_reloaded_address)
New functions.
(in_operand): Allow constants with MODE_PARTIAL_INT.
(out_operand): Allow special registers with any mode.
Any MEM a word or wider is valid.
(extend_operator): Deleted.
(secondary_reload_class): A pseudo is the same as memory; we need
BP_REGS for multi-word memory or for bytes and halfword if -mndw.
(print_operand): Delete %X; add %m.
(print_operand, case 'F'): Check for SYMBOL_REF.
* a29k.h (PROMOTE_MODE, ADJUST_COST): New macros.
(CALL_USED_REGISTERS): LR0 is call-used.
(HARD_REGNO_MODE_OK): Handle MODE_PARTIAL_INT and the special
registers that can only hold those modes.
(MODES_TIEABLE_P): Clean up and handle MODE_PARTIAL_INT modes.
(enum reg_class, REG_CLASS_NAMES, REG_CLASS_CONTENTS): Add new
classes LR0_REGS, FC_REGS, and CR_REGS.
(REGNO_REG_CLASS, REG_CLASS_FROM_LETTER): Likewise.
(PREDICATE_CODES): Update for new and deleted predicates.
* a29k.md: Use GEN_INT when appropriate.
(define_attr type): New types for SQRT.
(call patterns): Use SCRATCH for LR0.
Use new predicate call_operand so that some integers can be
used as addresses; fix CALLI so it doesn't accept constant.
(EXBYTE, EXTHW, INBYTE, INHW): Use ZERO_EXTEND instead of AND
when combine will make it.
Use PSImode for BP value and don't reference BP explicitly.
Clean up define_expands for these operations.
(rotlsi3): Use PSImode pseudo for FC.
(sign_extend): Sign extension insns clobber BP.
({load,store}_multiple): Use PSImode pseudo for CR.
(MTSR): Add pattern for TRUNCATE from SImode to PSImode.
(sqrtsf2, sqrtdf2, movpsi): New patterns.
