(handle_directive): Likewise.
(do_line): Likewise.
1998-12-07 Zack Weinberg <zack@rabi.phys.columbia.edu>
* cpplib.c (initialize_char_syntax): Use ISALPHA and ISALNUM
so it'll work on non-ASCII platforms. Always consider $ an
identifier character. Take no arguments.
(cpp_reader_init): Call initialize_char_syntax with no
arguments.
(cpp_start_read): Don't call initialize_char_syntax again.
Clear is_idchar['$'] and is_idstart['$'] if not
opts->dollars_in_ident.
* cpplib.h (struct cpp_reader): Replace void *data element by
cpp_options *opts. Rearrange elements to make gdb printout
less annoying (put buffer stack at end).
(CPP_OPTIONS): Get rid of now-unnecessary cast.
* cppmain.c: s/data/opts/ when initializing cpp_reader
structure.
* c-decl.c: Likewise.
* objc/objc-act.c: Likewise.
* fix-header.c: Likewise.
1998-12-07 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]
Mon Dec 7 15:38:25 1998 Dave Brolley <brolley@cygnus.com>

Sun Dec 6 07:49:29 1998 Alexandre Oliva <oliva@dcc.unicamp.br>
* gcc.texi (Bug Reporting): 40Kb is a soft limit, larger
compressed reports are ok and preferred over URLs.
Sun Dec 6 07:45:33 1998 Alexandre Oliva <oliva@dcc.unicamp.br>
* invoke.texi (Warning Options): Soften the tone of -pedantic.
Sun Dec 6 00:20:44 1998 H.J. Lu (hjl@gnu.org)

N_OUTPUTS args. All callers changed.
Compute number of inputs and outputs here by calling
get_asm_operand_n_inputs.

constrain_operands and preprocess_constraints. Use information
computed by these functions throughout.
(record_reg_life): Delete code that is unused due to changes in
record_asm_reg_life.
(subst_asm_stack_regs): Delete OPERANDS, OPERAND_LOC, CONSTRAINTS,
N_INPUTS and N_OUTPUTS args. All callers changed.

Thu Dec 3 11:19:50 1998 Mike Stump <mrs@wrs.com>

runs in the context of the deleter, not the deletee, so we must
use taskVarGet to find the correct memory to free.
(__gthread_key_create): Initialize the task
variable subsystem so that the task variable is still active when
the delete hook is run.
1998-12-03 Joseph S. Myers <jsm28@cam.ac.uk>
