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.

* reload1.c (reload): Update comments.
* md.texi: Corresponding changes.
* reload1.c (reg_used_in_insn): Renamed from reg_used_by_pseudo.
(choose_reload_regs): Rename it here as well. When computing it,
also merge in used hardregs.

* g77.f-torture/execute/u77-test.f (main): Avoid testing [f]statb
element, which fails on some systems.
* g77.f-torture/execute/labug1.f: New test.
From-SVN: r23854

From-SVN: r23845
* lex.c (handle_generic_pragma): Use token_buffer.
* decl.c (check_tag_decl): Don't complain about null friend decl.

CLASSTYPE_ABSTRACT_VIRTUAL, rather than recalculate.
* class.c (finish_struct_bits): Don't bother working out whether
get_abstract_virtuals will do anything, just do it.

context mechanism to save globals before calling jcf_parse.
(jcf_parse_source): Don't parse twice if HAS_BEEN_ALREADY_PARSED_P

* parse.y (java_push_parser_context): Use xmalloc.
(java_parser_context_restore_global): Pop extra pushed ctxp only
when there's nothing next.
(maybe_create_class_interface_decl): Fixed comment, add new
created class decl to all_class_list.
(method_header): Use GET_REAL_TYPE on argument's types.

type in TREE_LIST dependency node. Build argument list with the
real type.

* java-tree.def (CASE_EXPR, DEFAULT_EXPR): Kind is 'x', not '1'.

set TREE_SIDE_EFFECTS (otherwise expand_expr may skip them).

* class.c (add_method): Build up OVERLOADs properly for conversion ops.
* search.c (lookup_conversions): Handle getting real OVERLOADs.
(add_conversions): Likewise. Revert last change.
* call.c (add_conv_candidate): Pass totype to add_candidate instead
of fn. Don't add a new candidate if the last one was for the same
type.
(print_z_candidates): Handle getting a type as a function.
(joust): If we got two conversion candidates to the same type,
just pick one.
(build_object_call): Lose 'templates'.
(build_user_type_conversion_1): Handle getting real OVERLOADs.
Fixes g++.jason/overload7.C.
From-SVN: r23822
* typeck2.c (process_init_constructor): If there are elements
that don't have initializers and they need to have constructors
run, supply them with initializers.
Fixes Sec12/6_1/P12176.C.
* class.c (finish_struct_1): A class with a 0-width bitfield is
still empty.
Fixes Sec9/6/R09387.r0. Really this time.
From-SVN: r23819
* libgcc2.c (top_elt): Remove top_elt, it isn't thread safe.
The strategy we now use is to pre allocate the top_elt along
with the EH context so that each thread has its own top_elt.
This is necessary as the dynmanic cleanup chain is used on the
top element of the stack and each thread MUST have its own.
(eh_context_static): Likewise.
(new_eh_context): Likewise.
(__sjthrow): Likewise.
