Delete ancient instructions for compiling GCC on 3b1.
* INSTALL: Regenerate.
* cppfiles.c, cpplib.h, jump.c, protoize.c, c-lex.c,
ch/decl.c, ch/lex.c, cp/lex.c, f/lex.c, mips/t-ecoff,
mips/t-elf, mips/t-r3900: Remove references to cccp.c.
* convex.h, fx80.h, m68k.h, pdp11.h, contrib/gcc_update,
f/g77install.texi: Remove references to cexp.c/cexp.y.

which is no longer tested anywhere.

alpha/vms-tramp.asm.
From-SVN: r33238
* Makefile.in ($(srcdir)/c-parse.y: c-parse.in): Enclose the whole
message in quotes. Otherwise, IBM's make program treats the '#' as the
start of a comment and ignores the remainder of the line.

upper case.
* cccp.c (initialize_char_syntax): Allow for holes in EBCDIC.

(file_cleanup): Set control_macro and clear
input_stack_listing_current here.
(_cpp_execute_include): Don't output entering-file marker.

make unique nominal_fnames if necessary.
(do_elif, do_else, _cpp_handle_eof): Call cpp_error_with_line
with 0 for column, not -1.

(macro_cleanup): No need to cast pbuf->macro.
(collect_expansion): Use _cpp_get_define_token. Goto done if
it returns VSPACE. Remove check for trailing space after
CPP_COMMENT.
(_cpp_create_definition): Don't diddle flags here. Return
directly on error.
(unsafe_chars): Handle c1 being EOF.
(push_macro_expansion): Use unsafe_chars for both accidental-paste

them.
* cpplex.c (PEEKBUF, GETBUF, FORWARDBUF): New.

appropriately.
(_cpp_parse_assertion): Don't NUL terminate.
(_cpp_lex_token): Fix -traditional macro handling. Don't skip
hspace before calling _cpp_parse_assertion. Remove all sets
of only_seen_white. Treat '\f' as hspace. Don't do anything
special with '\n' here.
(maybe_macroexpand): Handle T_EMPTY hash entries without
pushing a buffer at all.
(cpp_get_token): Handle clearing only_seen_white here. Handle
incrementing the line number here. Clear
potential_control_macro as well as only_seen_white, if
appropriate.
(cpp_get_non_space_token): Don't eat CPP_POP tokens.
(_cpp_get_define_token): New function, basically like
_cpp_get_directive_token was but doesn't eat horizontal space.
Don't do anything with only_seen_white here.
(_cpp_get_directive_token): Just call _cpp_get_define_token
repeatedly till it returns non-hspace.

an error for a bogus directive, unless -lang-asm. Use
TRAD_DIRECT_P. Loop calling handler functions till one returns
zero.

(do_define): Diddle flags here. Use _cpp_get_directive_token.
Create T_EMPTY nodes for #define macro /* nothing */.
(do_undef): Don't copy the name. Use _cpp_get_directive_token.
Use hp->name when calling pass_thru_directive.
(do_if, do_else, do_elif, do_ifdef, do_ifndef, conditional_skip):
Return the result of conditional_skip and/or skip_if_group.
Don't call _cpp_output_line_command.
(consider_directive_while_skipping): Use _cpp_get_directive_token.
Issue -Wtraditional warnings as appropriate. Don't complain
about unrecognized directives. If we are to stop skipping,
return the number of the directive that ended the skip.
(skip_if_group): Use _cpp_get_directive_token. Turn off macro
expansion and line commands while skipping. Return the result
of consider_directive_while_skipping, if nonzero.
(do_endif): Just set potential_control_macro here.
(validate_else): Use _cpp_get_directive_token.
(do_assert, do_unassert): Don't save pointers into the
token_buffer across calls to the lexer. Use
_cpp_get_directive_token.
* cpplib.h (cpp_buffer): Remove alimit and colno. Make mark a
pointer, not an offset. Replace 'data', which was a generic
pointer, with 'macro', which points to a struct hashnode.
(cpp_reader): Add 'potential_control_macro' pointer.

(CPP_BUF_GET, CPP_FORWARD): Delete.
(CPP_IN_COLUMN_1, ADJACENT_TO_MARK): New macros.

From-SVN: r32965
* cpplib.h: Merge struct cpp_options into struct cpp_reader.
Reorder struct cpp_options and struct cpp_reader for better
packing. Replace CPP_OPTIONS macro with CPP_OPTION which
takes two args. Change all 'char' flags to 'unsigned char'.
Move show_column flag into struct cpp_options. Don't
prototype cpp_options_init.
* cpphash.h, cpperror.c, cppexp.c, cppfiles.c, cpphash.c,
cppinit.c, cpplex.c, cpplib.c:
Replace CPP_OPTIONS (pfile)->whatever with
CPP_OPTION (pfile, whatever), and likewise for
opts = CPP_OPTIONS (pfile); ... opts->whatever;

Extract CPP_OPTION (pfile, pending) and work with that
directly.
(cpp_options_init): Delete.
(cpp_reader_init): Turn on on-by-default options here.
Allocate the pending structure here.
(cl_options, enum opt_code): Define these from the same table,
kept in a large macro. Add -fshow-column and -fno-show-column
options.

the column number.
