From: Paul Eggert Date: Sun, 26 Feb 2017 17:56:44 +0000 (-0800) Subject: Remove a few unused C functions X-Git-Tag: emacs-26.0.90~706 X-Git-Url: http://git.eshelyaron.com/gitweb/?a=commitdiff_plain;h=d83c75ec19b549a1700622157d0ee292ca59785e;p=emacs.git Remove a few unused C functions * src/eval.c (let_shadows_global_binding_p): * src/print.c (write_string): * src/systhread.c (sys_mutex_destroy, sys_thread_equal): Remove. * src/print.c (write_string): Rename from write_string_1. All uses changed. --- diff --git a/src/eval.c b/src/eval.c index 22b02b49521..9b36ee04ed2 100644 --- a/src/eval.c +++ b/src/eval.c @@ -3213,18 +3213,6 @@ let_shadows_buffer_binding_p (struct Lisp_Symbol *symbol) return 0; } -bool -let_shadows_global_binding_p (Lisp_Object symbol) -{ - union specbinding *p; - - for (p = specpdl_ptr; p > specpdl; ) - if ((--p)->kind >= SPECPDL_LET && EQ (specpdl_symbol (p), symbol)) - return 1; - - return 0; -} - static void do_specbind (struct Lisp_Symbol *sym, union specbinding *bind, Lisp_Object value, enum Set_Internal_Bind bindflag) diff --git a/src/lisp.h b/src/lisp.h index e048011a860..238c20bc189 100644 --- a/src/lisp.h +++ b/src/lisp.h @@ -3707,7 +3707,6 @@ extern Lisp_Object Vprin1_to_string_buffer; extern void debug_print (Lisp_Object) EXTERNALLY_VISIBLE; extern void temp_output_buffer_setup (const char *); extern int print_level; -extern void write_string (const char *); extern void print_error_message (Lisp_Object, Lisp_Object, const char *, Lisp_Object); extern Lisp_Object internal_with_output_to_temp_buffer @@ -3848,7 +3847,6 @@ extern void mark_specpdl (union specbinding *first, union specbinding *ptr); extern void get_backtrace (Lisp_Object array); Lisp_Object backtrace_top_function (void); extern bool let_shadows_buffer_binding_p (struct Lisp_Symbol *symbol); -extern bool let_shadows_global_binding_p (Lisp_Object symbol); #ifdef HAVE_MODULES /* Defined in alloc.c. */ diff --git a/src/print.c b/src/print.c index d8acf838749..85a6c4627e1 100644 --- a/src/print.c +++ b/src/print.c @@ -522,23 +522,13 @@ print_c_string (char const *string, Lisp_Object printcharfun) Do not use this on the contents of a Lisp string. */ static void -write_string_1 (const char *data, Lisp_Object printcharfun) +write_string (const char *data, Lisp_Object printcharfun) { PRINTPREPARE; print_c_string (data, printcharfun); PRINTFINISH; } -/* Used from outside of print.c to print a C unibyte - string at DATA on the default output stream. - Do not use this on the contents of a Lisp string. */ - -void -write_string (const char *data) -{ - write_string_1 (data, Vstandard_output); -} - void temp_output_buffer_setup (const char *bufname) @@ -888,7 +878,7 @@ print_error_message (Lisp_Object data, Lisp_Object stream, const char *context, Lisp_Object errname, errmsg, file_error, tail; if (context != 0) - write_string_1 (context, stream); + write_string (context, stream); /* If we know from where the error was signaled, show it in *Messages*. */ @@ -934,7 +924,7 @@ print_error_message (Lisp_Object data, Lisp_Object stream, const char *context, const char *sep = ": "; if (!STRINGP (errmsg)) - write_string_1 ("peculiar error", stream); + write_string ("peculiar error", stream); else if (SCHARS (errmsg)) Fprinc (errmsg, stream); else @@ -945,7 +935,7 @@ print_error_message (Lisp_Object data, Lisp_Object stream, const char *context, Lisp_Object obj; if (sep) - write_string_1 (sep, stream); + write_string (sep, stream); obj = XCAR (tail); if (!NILP (file_error) || EQ (errname, Qend_of_file) || EQ (errname, Quser_error)) diff --git a/src/systhread.c b/src/systhread.c index a1b3eae64a6..a84060c18f0 100644 --- a/src/systhread.c +++ b/src/systhread.c @@ -38,11 +38,6 @@ sys_mutex_unlock (sys_mutex_t *m) { } -void -sys_mutex_destroy (sys_mutex_t *m) -{ -} - void sys_cond_init (sys_cond_t *c) { @@ -75,12 +70,6 @@ sys_thread_self (void) return 0; } -int -sys_thread_equal (sys_thread_t x, sys_thread_t y) -{ - return x == y; -} - int sys_thread_create (sys_thread_t *t, const char *name, thread_creation_function *func, void *datum) @@ -119,12 +108,6 @@ sys_mutex_unlock (sys_mutex_t *mutex) pthread_mutex_unlock (mutex); } -void -sys_mutex_destroy (sys_mutex_t *mutex) -{ - pthread_mutex_destroy (mutex); -} - void sys_cond_init (sys_cond_t *cond) { @@ -161,12 +144,6 @@ sys_thread_self (void) return pthread_self (); } -int -sys_thread_equal (sys_thread_t one, sys_thread_t two) -{ - return pthread_equal (one, two); -} - int sys_thread_create (sys_thread_t *thread_ptr, const char *name, thread_creation_function *func, void *arg) @@ -229,17 +206,6 @@ sys_mutex_unlock (sys_mutex_t *mutex) LeaveCriticalSection ((LPCRITICAL_SECTION)mutex); } -void -sys_mutex_destroy (sys_mutex_t *mutex) -{ - /* FIXME: According to MSDN, deleting a critical session that is - owned by a thread leaves the other threads waiting for the - critical session in an undefined state.
