(do_spec_1): Likewise.
(is_directory): Likewise.
(main): Likewise.
* prefix.c (IS_DIR_SEPARATOR): Define. Tests whether a character is
a directory separator.
(translate_name): Use it.

warning in block where '/' is changed to DIR_SEPARATOR.
* i386/xm-djgpp.h (DIR_SEPARATOR): Set to '/'.
(DIR_SEPARATOR_2): New macro. Set to '\'.
(HAVE_DOS_BASED_FILESYS): Define.

Add new argument MARK_LABELS_ONLY. Quit after mark_all_labels if
requested.
(jump_optimize, rebuild_jump_labels): New wrapper functions for
jump_optimize_1.
* toplev.c (rest_of_compilation): Use rebuild_jump_labels instead of
running the entire jump optimizer.

* pdp11.h (TARGET_SWITCHES): Add option to vary assembler syntax.
(TARGET_DEFAULT): Possibly use UNIX syntax.
(TARGET_UNIX_ASM, TARGET_UNIX_ASM_DEFAULT): New macros.
(REGISTER_NAMES): Use "r5" instead of "fp".
(ASM_OUTPUT_ALIGN): Use ".even" directive, and abort for any
greater alignment.
* 2bsd.h (TARGET_UNIX_ASM_DEFAULT): Default to UNIX assembler
syntax for 2BSD.
* pdp11.c (output_ascii): Use working syntax for ".byte".
(print_operand_address): Use "*" instead of "@" when using UNIX
assembler syntax.

* rtl.h (local_alloc): Returns an integer now.
* local-alloc.c (recorded_label_ref): New file scoped variable.
(local_alloc): Initialize recorded_label_ref to zero. Return its
value when local allocation has completed.
(update_equiv_regs); If we create an equivalence for a LABEL_REF,
set recorded_label_ref.
* toplev.c (rest_of_compilation): Run the loop optimizer after
register allocation and reloading if needed.

* cpphash.c (special_symbol): When expanding __LINE__, use the
top file buffer, not the top buffer.

1999-04-01 Jim Blandy <jimb@zwingli.cygnus.com>
* cplus-dem.c: Attempt to handle overflows in counts with some
semblance of grace.
(consume_count): Detect overflows. Return -1 to indicate errors,
instead of zero.
(demangle_template_value_parm, demangle_template): Handle change
to consume_count's return convention.
From-SVN: r26309
* expr.c (expand_expr, case ARRAY_REF, COMPONENT_REF, BIT_FIELD_REF):
Do not try to optimize a aggregate address which has VOIDmode.
Mirrors March 23 change to expand_assignment.

* flow.c (delete_unreachable_blocks): Do not require an edge to
be marked with EDGE_FALLTHRU when tidying an edge which connects
consecutive basic blocks.
* flow.c (can_delete_label_p): Do not convert a label into a
deleted label here.
From-SVN: r26306
* cse.c (flush_hash_table): New function.
(cse_insn): Flush the hash table when we encounter a volatile asm.
(cse_basic_block): Use flush_hash_table instead of doing it
inline.
* reload1.c (reload_cse_regs_1): Flush known register values if
we encounter a volatile asm.
From-SVN: r26304
* configure.in (host_xm_file, build_xm_file): Include hwint.h.
Use case statements instead of "if test -a ... -a ... -a ..."
* machmode.h: Don't define HOST_WIDE_INT, etc. Wrap use of
HOST_WIDE_INT in #ifdef.
* mips.h: Include hwint.h instead of providing definitions for
HOST_WIDE_INT, etc. Wrap uses of HOST_WIDE_INT in #ifdef.
From-SVN: r26291
