+
+ * callint.c (quotify_arg, quotify_args): Now static.
+
+ * lisp.h (get_system_name, get_operating_system_release):
+ Move decls here, to check interfaces.
+ * process.c (get_operating_system_release): Move decl to lisp.h.
+ * xrdb.c (get_system_name): Likewise.
+ * editfns.c (init_editfns, Fuser_login_name, Fuser_uid):
+ (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
+ some of which prompt warnings from gcc -Wbad-function-cast.
+ (Fformat_time_string, Fencode_time, Finsert_char):
+ (Ftranslate_region_internal, Fformat):
+ Rename or remove local vars to avoid shadowing.
+ (Ftranslate_region_internal): Mark var as initialized.
+
+2011-03-15 Paul Eggert <eggert@cs.ucla.edu>
+
+ * doc.c (Fdocumentation, Fsnarf_documentation): Move locals to
+ avoid shadowing.
+
+ * lisp.h (eassert): Check that the argument compiles, even if
+ ENABLE_CHECKING is not defined.
+
+ * data.c (Findirect_variable): Name an expression, to avoid
+ gcc -Wbad-function-cast warning.
+ (default_value, arithcompare, arith_driver, arith_error): Now static.
+ (store_symval_forwarding): Rename local to avoid shadowing.
+ (Fmake_variable_buffer_local, Fmake_local_variable): Mark
+ variables as initialized.
+ (do_blv_forwarding, do_symval_forwarding): Remove; unused.
+
+ * alloc.c (check_cons_list): Do not define unless GC_CHECK_CONS_LIST.
+ (Fmake_vector, Fvector, Fmake_byte_code, Fgarbage_collect):
+ Rename locals to avoid shadowing.
+ (mark_stack): Move local variables into the #ifdef region where
+ they're used.
+ (BLOCK_INPUT_ALLOC, UNBLOCK_INPUT_ALLOC): Define only if
+ ! defined SYSTEM_MALLOC && ! defined SYNC_INPUT, as they are not
+ needed otherwise.
+ (CHECK_ALLOCATED): Define only if GC_CHECK_MARKED_OBJECTS.
+ (GC_STRING_CHARS): Remove; not used.
+ (Fmemory_limit): Cast sbrk's returned value to char *.
+
+ * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this
+ avoids undefined behavior in theory.
+
+ * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
+
+ Use functions, not macros, for up- and down-casing (Bug#8254).
+ * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
+ (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
+ to use the following functions instead of these macros.
+ (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
+ EMACS_INT, since callers assume the returned value fits in int.
+ (upcase1): Likewise, for UPCASE_TABLE.
+ (uppercasep, lowercasep, upcase): New static inline functions.
+ * editfns.c (Fchar_equal): Remove no-longer-needed workaround for
+ the race-condition problem in the old DOWNCASE.
+
+ * regex.c (CHARSET_LOOKUP_RANGE_TABLE_RAW, POP_FAILURE_REG_OR_COUNT):
+ Rename locals to avoid shadowing.
+ (regex_compile, re_match_2_internal): Move locals to avoid shadowing.
+ (regex_compile, re_search_2, re_match_2_internal):
+ Remove unused local vars.
+ (FREE_VAR): Rewrite so as not to use empty "else",
+ which gcc can warn about.
+ (regex_compile, re_match_2_internal): Mark locals as initialized.
+ (RETALLOC_IF): Define only if needed.
+ (WORDCHAR_P): Likewise. This one is never needed, but is used
+ only in a comment talking about a compiler bug, so put inside
+ the #if 0 of that comment.
+ (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
+ (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
+ Remove; unused.
+
+ * search.c (boyer_moore): Rename locals to avoid shadowing.
+ * character.h (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE):
+ (PREV_CHAR_BOUNDARY): Likewise.
+
+ * search.c (simple_search): Remove unused var.
+
+ * dired.c (compile_pattern): Move decl from here ...
+ * lisp.h: ... to here, so that it can be checked.
+ (struct re_registers): New forward decl.
+
+ * character.h (INC_POS, DEC_POS): Rename locals to avoid shadowing.
+
+ * indent.c (MULTIBYTE_BYTES_WIDTH): New args bytes, width.
+ All uses changed.
+ (MULTIBYTE_BYTES_WIDTH, scan_for_column, compute_motion):
+ Rename locals to avoid shadowing.
+ (Fvertical_motion): Mark locals as initialized.
+
+ * casefiddle.c (casify_object, casify_region): Now static.
+ (casify_region): Mark local as initialized.
+
+ * cmds.c (internal_self_insert): Rename local to avoid shadowing.
+
+ * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
+ New macros, so that the caller can use some names other than
+ gcpro1, gcpro2, etc.
+ (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
+ of the new macros.
+ (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
+ argument, for consistency with GCPRO2_VAR, etc: it is now the
+ prefix of the variable, not the variable itself. All uses
+ changed.
+ * dired.c (directory_files_internal, file_name_completion):
+ Rename locals to avoid shadowing.
+
+ Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
+ An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
+ dired.c's scmp function, had undefined behavior.
+ * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
+ (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
+ * buffer.h: ... to here, because these macros use current_buffer,
+ and the new implementation with inline functions needs to have
+ current_buffer in scope now, rather than later when the macros
+ are used.
+ (downcase, upcase1): New static inline functions.
+ (DOWNCASE, UPCASE1): Reimplement using these functions.
+ This avoids undefined behavior in expressions like
+ DOWNCASE (x) == DOWNCASE (y), which previously suffered
+ from race conditions in accessing the global variables
+ case_temp1 and case_temp2.
+ * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
+ * lisp.h (case_temp1, case_temp2): Remove their decls.
+ * character.h (ASCII_CHAR_P): Move from here ...
+ * lisp.h: ... to here, so that the inline functions mentioned
+ above can use them.
+
+ * dired.c (directory_files_internal_unwind): Now static.
+
+ * fileio.c (file_name_as_directory, directory_file_name):
+ (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
+ Now static.
+ (file_name_as_directory): Use const pointers when appropriate.
+ (Fexpand_file_name): Likewise. In particular, newdir might
+ point at constant storage, so make it a const pointer.
+ (Fmake_directory_internal, Fread_file_name): Remove unused vars.
+ (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
+ signedness issues.
+ (Fset_file_times, Finsert_file_contents, auto_save_error):
+ Rename locals to avoid shadowing.
+
+ * minibuf.c (choose_minibuf_frame_1): Now static.
+ (Ftry_completion, Fall_completions): Rename or remove locals
+ to avoid shadowing.
+
+ * marker.c (bytepos_to_charpos): Remove; unused.
+
+ * lisp.h (verify_bytepos, count_markers): New decls,
+ so that gcc does not warn that these functions aren't declared.
+
+ * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
+ (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
+ (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
+ (copy_text): Remove unused local var.
+
+ * filelock.c (within_one_second): Now static.
+ (lock_file_1): Rename local to avoid shadowing.
+
+ * buffer.c (fix_overlays_before): Mark locals as initialized.
+ (fix_start_end_in_overlays): Likewise. This function should be
+ simplified by using pointers-to-pointers, but that's a different
+ matter.
+

+
+ * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
+ Fix pointer signedness issue.
+ (sys_subshell): Mark local as volatile if checking for lint,
+ to suppress a gcc -Wclobbered warning that does not seem to be right.
+ (MAXPATHLEN): Define only if needed.
+
+ * process.c (serial_open, serial_configure): Move decls from here ...
+ * systty.h: ... to here, so that they can be checked.

+ (decode_keyboard_code, tty_read_avail_input, menu_bar_items):
+ (parse_tool_bar_item, read_key_sequence, Fread_key_sequence):
+ (Fread_key_sequence_vector): Rename locals to avoid shadowing.

+ * alloc.c (mark_kboards): ... from here.
+
+ * lisp.h (force_auto_save_soon): New decl.
+
* emacs.c (init_cmdargs): Rename local to avoid shadowing.
(DEFINE_DUMMY_FUNCTION): New macro.
