* c_num: now takes self argument.Kaz Kylheku2020-06-291-3/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The c_num and c_unum functions now take a self argument for identifying the calling function. This requires changes in a large number of places. In a few places, additional functions acquire a self argument. The ffi module has the most extensive example of this. Some functions mention their name in a larger string, or have scattered literals giving their name; with the introduction of the self local variable, these are replaced by references to self. In the following changelog, the notation TS stands for "take self argument", meaning that the functions acquires a new "val self" argument. The notation DS means "define self": the functions in question defines a self variable, which they pass down. The notation PS means that the functions pass down an existing self variable to functions that now require it. * args.h (args_count): TS. * arith.c (c_unum, c_num): TS.

* arith: move c_unum and unum declaration into lib.hKaz Kylheku2020-04-221-1/+0
| | | | | | | | | | | | | | | | The c_unum and unum functions are fairly often needed and and are closely related to c_num and num, which have always been declared in lib.h even though they live in arith.c. Files not doing arithmetic are including "arith.h" just for the sake of c_num or unum. * arith.h (c_unum, unum): Declarations removed. * lib.h (c_unum, unum): Declarations moved here. * chksum.c, debug.c, stream.c, strudel.c, sysif.c, vm.c: These files no longer require #include "arith.h" as a result, which is therefore removed.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | TXR is moving to custom assembly-language routines. This is mainly motivated by a very dubious thing done in the GNU C Library setjmp and longjmp in the name of security. Evidently, glibc's setjmp "mangles" certain pointer values which are stored into the jmp_buf buffer. It's been that way since 2005, evidently. This means that, firstly, all along, the use of setjmp in gc.c to get registers into a buffer so they can be scanned has not actually worked properly. More importantly, this pointer mangling in setjmp and longjmp is very hostile to a stack copying implementation of delimited continuations. The reason is that continuations contain jmp_buf buffers, which get relocated in the process of capturing and reviving a continuation. Any pointers in a jmp_buf which point into the captured stack segment have to be fixed up to point into the relocated location. Mangled pointers make this difficult, requiring hacks which are specific to glibc and the machine architecture. We might as well implement a clean, well-behaved setjmp and longjmp. * Makefile (jmp.o): New object file. (dbg/%.o, opt/%.o): New rules for .S prerequisites. * args.c, arith.c, cadr.c, combi.c, cadr.c, combi.c, debug.c, eval.c, filter.c, glob.c, hash.c, lib.c, match.c, parser.c, rand.c, regex.c, signal.c, stream.c, struct.c, sysif.c, syslog.c, txr.c, unwind.c, utf8.c: Removed <setjmp.h> include. * gc.c: Switch to struct jmp and jmp_save, instead of jmp_buf and setjmp. * jmp.S: New source file. * signal.h (struct jmp): New struct type. (jmp_save, jmp_restore): New function declarations denoting assembly language routines in jmp.S. (extended_jmp_buf): Uses struct jmp instead of setjmp.

Dot position evaluation is handled by installing the dot position value as args->list. (do_eval): Allocate args of at least ARGS_MAX for the call to do_eval_args. Then use generic_funcall to invoke the function rather than apply. (eval_args_lisp1): Modified similarly to do_eval_args. (eval_lisp1): New static function. (expand_macro): Construct struct args argument list for the sake of debug_frame. (op_dwim): Allocate args which are filled by eval_args_lisp1, and applied to the function/object with generic_funcall. The object expression is separately evaluated with eval_lisp1. * match.c (h_fun, v_fun): Construct struct args arglist for the sake of debug_frame call. * unwind.c (uw_push_debug): args argument becomes struct args *. * unwind.h (struct uw_debug): args member becomes struct args *. (uw_push_debug): Declaration updated. * txr.1: Update documentation about dot position argument in function calls. (list . a) now works, which previously didn't.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This speeds up the TXR Lisp interpreter, because do_eval sets up a debug frame and uses debug_return. * debug.c (debug_block_s): Symbol removed. (debug_init): Remove initialization of debug_block_s. * debug.h (debug_block_s): Declaration removed. (debug_enter): Do not establish a named block or a catch block; no time-wasting unwind stack manipulation at all. The debug_depth variable is managed by the extended setjmp context now. Provide a return value variable, and a well-defined name to branch to to exit from the debug block. (debug_return): Do not use heavy-weight uw_block_return; simply set the return variable and branch to debug_return_out label. * signal.h (EJ_DBG_MEMB, EJ_DBG_SAVE, EJ_DBG_REST, EJ_OPT_MEMB, EJ_OPT_SAVE, EJ_OPT_REST): New macros. (extended_jmp_buf): Define optional global state variables using EJ_OPT_MEMB. (extended_setjmp): Save and restore optional globals using EJ_OPT_SAVE and EJ_OPT_RESTORE. Now debug_depth is saved and restored if debugging support is compiled in. * match.c (open_data_source): Remove bogus debug_return invocations which were uncovered here by changes to the macro. * eval.c (do_eval, expand_macro): debug_return must now be after debug_end, because it won't dynamically clean up frames that it doesn't know about. The set_dyn_env is no longer unreachable in expand_macro; it is now necessary because debug_return isn't doing the longjmp that previously restored dyn_env.

The issue being solved here is the accuracy of the gc_set function. The existing impelmentation is too conservative. It has no generation information about the memory location being stored, and so it assumes the worst: that it is a location in the middle of a gen 1 object. This is sub-optimal, creating unacceptable pressure against the checkobj array and, worse, as a consequence causing unreachable gen 0 objects to be tenured into gen 1. To solve this problem, we replace "val *" pointers with a structure of type "loc" which keeps track of the object too, which lets us discover the generation. I tried another approach: using just a pointer with a bitfield indicating the generation. This turned out to have a serious issue: such a bitfield goes stale when the object is moved to a different generation. The object holding the memory location is in gen 1, but the annotated pointer still indicates gen 0.
