(init_expr_once): Don't try HARD_REGNO_MODE_OK on VOIDmode or BLKmode.
(emit_move_insn): When moving word by word,
mark the whole thing as a libcall block.
(group_insns): New function.
(expand_expr): Implement COMPLEX_EXPR, REALPART_EXPR, IMAGPART_EXPR, CONJ_EXPR.
From-SVN: r2082
(record_reg_class): For matching operands, handle
case where the earlier one is not a pseudo like the case
where the later one is not a pseudo.
From-SVN: r2067
* pa.c (output_function_prologue): Undo Aug. 13 change.
If profiling, then this function makes calls. Reflect this in
CALLINFO.
(output_function_epilogue): If profiling, then be restore "rp" here.
* pa.c (use_milli_regs): Deleted.
From-SVN: r2065
* pa.md (indirect_jump): Annul the next instruction if the delay
slot could not be filled instead of emitting a nop.
* pa.md (use_milli_regs attribute): Deleted, not necessary anymore.
All references deleted.

Use gen_lowpart to change mode of operand 0.
(storeinthi): Use match_operand for operand 0.
Change output code to reassign operand 0.
(truncsihi2, truncsiqi2, trunchiqi2): Remove these patterns.
From-SVN: r2057
(add_double, div_and_round_double, lshift_double, mul_double):
(neg_double, const_binop, fold): Check for signed integer overflow.
Propagate overflow flags from operands to result.
(const_binop, fold_convert): Use pedwarn for overflow warnings.
Say `constant expression', not `constant folding', for user's sake.
From-SVN: r2053
(SYSTEM_HEADER_DIR): New variable.
(xlimits.h): New target, broken out from install-limits-h.
Look in SYSTEM_HEADER_DIR for system's limits.h.
(start.encap): Dep on xlimits.h.
(install-limits-h): Install xlimits.h already made.

If we find a link pointing to ., make a similar
link to ., not a link to an absolute name.
(stdio.h): Change stdio.h to use stdarg.h to get va_list.
When link points to a dir $dirname outside $INPUT,
copy that dir into $LIB/root$dirname. Translate the link itself
into a link to that new dir. Make a file DONE in each treetop dir
so no treetop is scanned twice. Improve progress messages.
From-SVN: r2046
(default_compilers): Add missing comma between strings, so
that traditional compilers can compile gcc.c.
(main): Don't pass strcpy or strlen a NULL pointer if some of the
spec strings in default_compilers are NULL.
(validate_all_switches): Don't dereference a NULL pointer if some of
the spec strings in defalut_compilers are NULL.
From-SVN: r2039
* caller-save.c (init_caller_save): If we were unable to
find a simple insn which meets all its constraints to save
and restore with a single insn in a mode, then set
regno_save_mode to VOIDmode to insure that this mode is never
used to caller-save the current register.
