* cppfiles.c (read_and_prescan): When emitting deferred
newlines, test speccase[] again instead of checking each
possible whitespace character in turn. When we encounter \r,
look behind for \n first, then ahead.
From-SVN: r31963

* cppexp.c: Don't include cpphash.h.
(parse_charconst, cpp_lex): Use cpp_defined.
(cpp_lex): Use get_directive_token throughout. Remove
unnecessary cases from switch. Move assertion-handling code
down to OTHER case.
(cpp_parse_expr): If we see '+' or '-', check the context to
determine if they are unary or binary operators. Streamline
the jumps a bit. Do not call skip_rest_of_line.
* cpplib.c: Make skip_rest_of_line and cpp_skip_hspace
static. Export get_directive_token. Update commentary.
(cpp_defined): New function.
(do_define): Remove reference to T_PCSTRING. Call
free_definition to release memory for old definition, when
redefining a macro.
(eval_if_expression): Set only_seen_white to 0 before calling
cpp_parse_expr. Call skip_rest_of_line after it returns.
(cpp_read_check_assertion): Don't preserve a pointer into the
token buffer across a call to cpp_get_token.
* Makefile.in (cppexp.o): Don't depend on cpphash.h.
* cppfiles.c (redundant_include_p): Use cpp_defined.
* cpphash.c (free_definition): New function.
(delete_macro): Use it. Update commentary.
* cpphash.h: Typedef HASHNODE here. Prototype cpp_lookup and
free_definition.

(read_scan_file): Set inhibit_warnings and inhibit_errors in
the options structure.

* cpplib.h: Provide HASHNODE typedef and forward decl of
struct hashnode only. Kill cpp_hashnode typedef. MACRODEF,
DEFINITION, struct hashnode, struct macrodef, struct
definition, scan_decls prototype, default defn of
INCLUDE_LEN_FUDGE moved elsewhere.
* cpphash.h: MACRODEF, DEFINITION, struct macrodef, struct
definition, and struct hashnode moved here. Remove the unused
'predefined' field from struct definition. Replace the 'args'
union with its sole member. All users updated (cpphash.c).
Delete HASHSTEP and MAKE_POS macros, and hashf prototype. Add
multiple include guard.
* cpphash.c (hashf): Make static; use better algorithm; drop
HASHSIZE parameter; return an unsigned int.
(cpp_lookup): Drop HASH parameter. PFILE parameter is
used. Calculate HASHSIZE modulus here.

* cppfiles.c (read_and_prescan): Map backslash-newline to '\r'
(which cannot otherwise appear in the processed buffer) and
move it out of tokens that it appears in the middle of.
Improve performance.
(find_position): New function.
* cpplib.c: \r (one character) indicates backslash
newline, not \\\n (two characters). It cannot appear in the
middle of a token. Call CPP_BUMP_LINE (pfile) whenever
parsing moves past \n or \r. Increment pfile->lineno whenever
a \n is placed into token_buffer. Only one mark can exist at
a time, and CPP_BUMP_LINE must not be used while it is
active. It is automatically cleared by cpp_pop_buffer and
parse_goto_mark. \r is not in is_hor_space or is_space.
(NEWLINE_FIX, NEWLINE_FIX1, adjust_position,
update_position, count_newlines, parse_move_mark): Removed.
(parse_string, copy_comment): New functions.
(parse_name): Returns void.
(parse_set_mark, parse_clear_mark, parse_goto_mark): Take only

argument is now first character of comment marker; all callers
changed. Issue error for unterminated block comment here.
(cpp_skip_hspace): Recognize CHILL comments.
(copy_rest_of_line): Likewise. Call skip_comment and
parse_string directly, don't go through cpp_get_token. Emit
"/**/" for block comments if -traditional (create_definition
needs this).
(do_define): Don't play with put_out_comments.
(cpp_push_buffer): Initialize ->mark to -1.
(cpp_buf_line_and_col): Just read out the values in the buffer
structure.
(output_line_command): Use cpp_buf_line_and_col. Fix
formatting. Remove stale code.
(cpp_get_token): Break out string parsing code to
parse_string. Use skip_comment for CHILL comments too. Use
copy_comment for put_out_comments instead of dinking with
marks. Remove stale code. Don't call output_line_command
unless it's necessary.
* cpplib.h (parse_marker): Removed.
(struct cpp_buffer): line_base is now a unsigned char *; add
`mark' [long], remove `marks' [struct parse_marker *].
(parse_set_mark, parse_clear_mark, parse_goto_mark): Update
prototypes.
(CPP_BUMP_LINE, CPP_BUMP_BUFFER_LINE): New macros.
* cppinit.c (is_hor_space, is_space): '\r' is not considered

* cppinit.c: Instead of one pending list, keep separate lists
for each category of pending option: -D/-U, -A, -include,
-imacros. Move the four partial include-path lists into the
pending block. Use head and tail pointers so we don't ever
have to reverse the lists.
(cpp_start_read): Break out blocks of code to their own
functions: install_predefs and initialize_dependency_output.
Use path_include for C_INCLUDE_PATH and friends as well as
CPATH. Remove include_defaults gunk. Warn about the
combination of -lang-chill and -trigraphs. Optimize string
bashing. Walk each pending list once, deallocating as we go.
(append_include_chain): Brought over from cppfiles.c. Mark
dirs as system include dirs if and only if appending to
system include path. If opts->verbose, print a notice when a
dir is dropped from the include path because it doesn't
exist. Fix memory leak: this function is not supposed to copy
its DIR argument.
(nreverse_pending, push_pending): Removed.
(APPEND): New macro for adding to pending lists.
(path_include): Can now add to any partial include path.
(base_name): Bring over from cccp.c.

that was in cpp_start_read.
(initialize_dependency_output): Likewise. Understand OBJECT_SUFFIX.
* cppfiles.c (simplify_pathname): Export.
(merge_include_chains): Don't nreverse the lists. If
opts->verbose, print a notice when a duplicate dir is detected
and dropped from the include path.
(finclude): Fix excessive cleverness in setting
fp->system_header_p.
(actual_directory): Set x->sysp from
CPP_BUFFER (pfile)->system_header_p so that one system header
may include another with "".
(deps_output): Fix double adjustment of deps_size which would
cause all dependencies after the first two lines to be lost.
* cpplib.c (cpp_unassert): New function.
* cpplib.h: Lay out struct cpp_pending here. Adjust
prototypes. Add include_prefix_len to struct cpp_options.

terminators (\r, \n\r, \r\n). Warns about no newline at EOF.
(finclude): Use read_and_prescan; turn off nonblocking mode on
the input descriptor; remove file-size-examination and
no-newline-at-EOF gunk which is longer necessary; be more
careful about checking that we've been handed a legitimate
file to read (only real files, pipes, and ttys are acceptable).

`trigraphs' and invert its sense.
(trigraph_table): Declare.

file_name_list pointer.
1998-11-26 01:17 -0500 Zack Weinberg <zack@rabi.phys.columbia.edu>
* cpplib.h (struct cpp_buffer): Replace dir and dlen members
with a struct file_name_list pointer.
(struct cpp_reader): Add pointer to chain of `actual
directory' include searchpath entries.
(struct file_name_list): Add *alloc pointer for the sake of
the actual-directory chain.
Move definition of HOST_WIDE_INT here.
(cpp_parse_escape): Change prototype to match changes in
cppexp.c.
* cppfiles.c (actual_directory): New function.
(finclude): Use it to initialize the buffer's actual_dir
entry.
(find_include_file): We don't need to fix up max_include_len
here.
* cpplib.c (do_include): Don't allocate a file_name_list on
the fly for current directory "" includes, use the one that's
been preallocated in pfile->buffer->actual_dir. Hoist out
duplicate code from the search_start selection logic.
(cpp_reader_init): Initialize pfile->actual_dirs.
Remove definition of HOST_WIDE_INT. Change calls
to cpp_parse_escape to match changes in cppexp.c (note
hardcoded MASK, which is safe since this is the source
character set).
* cppexp.c: Bring over changes to cpp_parse_escape from cccp.c
to handle wide character constants in #if directives. The
function now returns a HOST_WIDE_INT, and takes a third
argument which is a binary mask for all legal values (0x00ff
for 8-bit `char', 0xffff for 16-bit `wchar_t', etc.) Define
MAX_CHAR_TYPE_MASK and MAX_WCHAR_TYPE_MASK. Change callers of
cpp_parse_escape to match. [Fixes c-torture/execute/widechar-1.c]

Wed Nov 25 14:54:46 1998 Zack Weinberg <zack@rabi.phys.columbia.edu>
* cpplib.h: Delete struct import_file. Add ihash element to
struct cpp_buffer. Delete dont_repeat_files and
import_hash_table elements from cpp_reader; change
all_include_files to a hash table. Delete all foobar_include
/ last_foobar_include elements from struct cpp_options; put
back four such: quote_include, bracket_include,
system_include, after_include. Redo struct file_name_list
completely. Add new structure type include_hash. Add
prototypes for merge_include_chains and include_hash. Change
prototypes for finclude, find_include_file, and
append_include_chain to match changes below.
* cppfiles.c (simplify_pathname, include_hash,
remap_filename, merge_include_chains): New functions.
(add_import, lookup_import, open_include_file): Removed.
(INO_T_EQ): Define this (copied from cccp.c).
(hack_vms_include_specification): Remove all calls and #if 0
out the definition. It was being called incorrectly and at
the wrong times. Until a VMSie can look at this, it's better
to not pretend to support it.
(append_include_chain): Change calling convention; now takes
only one directory at a time, and sets up the data structure
itself.
(redundant_include_p): Rewritten - this is now used for all
include redundancy, whether by #ifndef, #import, or #pragma
once. Looks up things in the include hash table.
(file_cleanup): Decrement pfile->system_include_depth here if
it's >0.
(find_include_file): Calling convention changed; now passes
around a struct include_hash instead of 3 separate parameters.
Guts ripped out and replaced with new include_hash mechanism.
(finclude): Calling convention changed as for
find_include_file. Error exits pulled out-of-line. Reformat.
(safe_read): Return a long, not an int.
(deps_output): Don't recurse.
* cpplib.c (is_system_include): Deleted.
(path_include): Fix up call to append_include_chain.
(do_include): Fix up calls to find_include_file and finclude.
Clean up dependency output a bit. Shorten obnoxiously lengthy
#import warning message. Don't decrement
pfile->system_include_depth here.
(do_pragma): Understand the include_hash structure. Reformat.
(do_endif): Correct handling of control macros. Understand
the include_hash.
(cpp_start_read): Fix up calls to finclude. Call
merge_include_chains.
(cpp_handle_option): Fix up calls to append_include_chain.
Understand the four partial include chains.
(cpp_finish): Add debugging code (#if 0-ed out) for the
include_hash.
(cpp_cleanup): Free the include_hash, not the import hash and
the all_include and dont_repeat lists which no longer exist.

* c-lang.c: Declare extern char *yy_cur if USE_CPPLIB.
(lang_init): Call check_newline always.
* c-lex.c (init_parse) [USE_CPPLIB=1]: After calling
cpp_start_read, set yy_cur and yy_lim to read from
parse_in.token_buffer, so that we'll see the first #line
directive.
* cpplib.c (cpp_start_read): finclude the main input file
before processing -include/-imacros. Process -imacros and
-include separately, and handle -include by stacking a
buffer for the file in question as if it'd been #included.
* toplev.c (documented_lang_options) Recognize -H when
USE_CPPLIB is on.
1998-10-28 16:09 -0500 Zack Weinberg <zack@rabi.phys.columbia.edu>

code out of do_include.
Move append_include_chain, deps_output,
file_cleanup, redundant_include_p, import_hash,
lookup_import, add_import, read_filename_string, read_name_map,
open_include_file, finclude, safe_read to cppfiles.c.
Move prototypes for deps_output, append_include_chain,
finclude to cpplib.h. Move definition of struct
file_name_list there also.
* cppfiles.c: New file. Contains all the above functions
broken out of cpplib.c; also hack_vms_include_specification
from cccp.c and find_include_file, a new function broken out of
do_include.
* Makefile.in (cppmain): Depend on cppfiles.o.
(fix-header): Likewise.
(cppfiles.o): New target.
* configure.in (--enable-c-cpplib): Add cppfiles.o to
extra_c_objs. Add ../cppfiles.o to extra_cxx_objs.
