2016-10-26Use atomics for async interruptsAndy Wingo1-117/+64
* libguile/__scm.h (SCM_TICK): Always define as scm_async_tick(). * libguile/error.c (scm_syserror, scm_syserror_msg): * libguile/fports.c (fport_read, fport_write): * libguile/_scm.h (SCM_SYSCALL): Replace SCM_ASYNC_TICK with scm_async_tick ().

(scm_call_with_blocked_asyncs, scm_c_call_with_blocked_asyncs) (scm_call_with_unblocked_asyncs, scm_c_call_with_unblocked_asyncs): Implement in terms of scm_dynwind_{un,}block_asyncs, so that we don't stuff SCM values into pointers.

CPP defines that were not previously issuing warnings were changed so that their expansions would indicate the replacement forms to use, e.g. scm_sizet__GONE__REPLACE_WITH__size_t. The two exceptions were SCM_LISTN, which did not produce warnings before, and the string-filter argument order stuff. Drops the initial dirty memory usage of Guile down to 2.8 MB on my machine, from 4.4 MB.

2009-12-05decruftify scm_sys_protectsAndy Wingo1-1/+0
* libguile/root.h * libguile/root.c (scm_sys_protects): It used to be that for some reason we'd define a special array of "protected" values. This was a little silly, always, but with the BDW GC it's completely unnecessary. Also many of these variables were unused, and none of them were good API. So remove this array, and either eliminate, make static, or make internal the various values. * libguile/snarf.h: No need to generate calls to scm_permanent_object. * guile-readline/readline.c (scm_init_readline): No need to call scm_permanent_object. * libguile/array-map.c (ramap, rafe): Remove the dubious nullvect optimizations. * libguile/async.c (scm_init_async): No need to init scm_asyncs, it is no more. * libguile/eval.c (scm_init_eval): No need to init scm_listofnull, it is no more. * libguile/gc.c: Make scm_protects a static var. (scm_storage_prehistory): Change the sanity check to use the address of protects. (scm_init_gc_protect_object): No need to clear the scm_sys_protects, as it is no more. * libguile/keywords.c: Make the keyword obarray a static var. * libguile/numbers.c: Make flo0 a static var. * libguile/objprop.c: Make object_whash a static var. * libguile/properties.c: Make properties_whash a static var. * libguile/srcprop.h: * libguile/srcprop.c: Make scm_source_whash a global with internal linkage. * libguile/strings.h: * libguile/strings.c: Make scm_nullstr a global with internal linkage. * libguile/vectors.c (scm_init_vectors): No need to init scm_nullvect, it's unused.
2009-10-09Arrange so that `SCM_I_CURRENT_THREAD' is not accessed outside of libguile.Ludovic Courtès1-0/+23
* libguile/__scm.h (scm_async_tick): New declaration.
