1996-12-18Give GCC more control flow information, so it can be sure thatJim Blandy1-1/+3
variables aren't used uninitialized. * error.h (scm_error, scm_syserror, scm_syserror_msg, scm_sysmissing, scm_num_overflow, scm_out_of_range, scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error, scm_misc_error): Tell GCC that these functions never return. * struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure out the field type, call abort if SCM_ASSERT returns, to placate the optimizer. * stacks.c (scm_make_stack, scm_last_stack_frame): abort if scm_wta ever returns. We can't handle this case anyway, and this gives the optimizer more information. * unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if scm_wta ever returns. In some cases, the code is fine, but GCC isn't smart enough to figure that out; this usually happens when one variable is only initialized and used when a particular condition holds true, and we know that condition will never change within a given invocation of the function. In this case, we simply initialize the variables to placate the compiler, hopefully to a value which will cause a crash if it is ever actually used. * print.c (scm_iprin1): Initialize mw_pos. * read.c (scm_lreadrecparen): Initialize tl2, ans2. * throw.c (scm_ithrow): Initialize dynpair. * unif.c (scm_uniform_vector_ref): Initialize cra. * struct.c (init_struct): Initialize prot. * mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
1996-10-15Allocate data for structures on an eight-byte boundary, asJim Blandy1-21/+65
required by the tagging system. * struct.c (alloc_struct): New function. (scm_make_struct, scm_make_vtable_vtable): Call it. * struct.h (scm_struct_n_extra_words): Bump to 3. (scm_struct_i_ptr): New "field". * gc.c (scm_gc_sweep): When we need to free the data, use the information stored by alloc_struct to find the beginning of the block allocated to the structure, so we can free it.

(Patch thanks to Marius Vollmer.)
1996-10-11* struct.c (scm_make_struct, scm_make_vtable_vtable): Use theJim Blandy1-2/+2
symbolic name for the tag, scm_tc3_cons_gloc, instead of just saying "1".
1996-09-22* struct.c (scm_make_struct_layout, init_struct, scm_struct_ref,Mikael Djurfeldt1-46/+94
scm_struct_set_x), struct.h, gc.c (scm_gc_mark): Completed Tom Lord's implementation of structs, allowing for tail arrays as described in the manual. Also fixed some bugs. (Both the interface and the implementation should be improved.)
1996-09-11* numbers.h: Repeated declarations removed.Jim Blandy1-1/+1
* ports.h (scm_close_all_ports_except): Declaration for the function defined in ports.c added. * posix.h: Missing declarations added. * procs.h (scm_make_subr_opt): Missing declaration added. * socket.h (scm_sys_gethost): Missing declaration added. * socket.h: Redundant declarations removed (they are in fdsocket.h). * srcprop.h (scm_set_source_property_x, scm_finish_srcprop): Missing declarations added. * stime.h (scm_get_internal_real_time): Repeated declarations removed. * struct.c: Uninitialized variable `SCM answer' may be used. * unif.c (l2ra): Declaration prototype. * unif.c (scm_array_equal_p): Dummy definition removed (it is defined in ramap.c). * unif.h (scm_raprin1, scm_istr2bve, scm_array_equal_p): Redundant declarations removed (they are in ramap.h). * variable.h (scm_make_udvariable, scm_make_undefined_variable): Declaration corrected to correspond variable.c. * vectors.h (scm_vector_move_left_x, scm_vector_move_right_x): Missing declarations added.
1996-09-10C files should #include only the header files they need, notJim Blandy1-0/+3
libguile.h (which #includes all the header files); the pointless recompilation was wasting my time. * Makefile.in (all .o dependency lists): Regenerated. * libguile.h: Don't try to get a definition for size_t here... * __scm.h: Do it here. * _scm.h: Since this is the internal libguile header, put things here that all (or a majority) of the libguile files will want. Don't #include <libguile.h> here; that generates dependencies on way too much.
