* * Fix bug#42360Andrea Corallo2020-07-151-6/+41
| | | | | | | * src/comp.c (compile_function): Allocate function frame as array if non local exits are present to retain correct Elisp semantic. (emit_limple_call_ref): Directly use the frame array for ref calls to have GCC spills into it before calling.

| * | Use Gnulib libgmp modulePaul Eggert2020-07-095-4916/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Instead of doing GMP by hand, use the Gnulib libgmp module. * .gitignore: Add lib/gmp.h. * admin/merge-gnulib (GNULIB_MODULES): Add libgmp. * configure.ac (GMP_LIB, GMP_OBJ): Remove. Gnulib uses the name LIB_GMP, so all uses changed. All uses of GMP_OBJ removed. (HAVE_GMP): Set this from Gnulib’s variables. * lib/gnulib.mk.in, m4/gnulib-comp.m4: Regenerate. * lib/mini-gmp-gnulib.c, lib/mini-gmp.c, lib/mini-gmp.h, m4/libgmp.m4: New files, copied from Gnulib. * src/bignum.h, test/data/emacs-module/mod-test.c: Include gmp.h unconditionally. * src/mini-gmp-emacs.c, src/mini-gmp.c, src/mini-gmp.h: Remove. This moves these files from src to lib, and updates them to the current GMP version. * test/Makefile.in (GMP_H): New macro. ($(test_module)): Use it to decide whether to compile mini-gmp-gnulib.c too.
* | | * Rework frame allocation strategyAndrea Corallo2020-07-131-61/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | All frame slots are now simple automatic variables given the array allocation and fill is done in 'emit_limple_call_ref'. * src/comp.c (comp_t): Remove 'f_frame' 'arrays' slots, add 'frame'. (emit_mvar_lval): Simplify to make use of 'comp.frame'. (compile_function): Clean-up and add comp.frame initialization.
* | | * Rework the backend to allocate arument arrays for call by referencesAndrea Corallo2020-07-131-20/+40
| | | | | | | | | | | | | | | | | | | | | * src/comp.c (comp_t): Add 'zero' field. (emit_limple_call_ref): Allocate an array to host the parametes and generate the code moving values into. (Fcomp__init_ctxt): Initialize comp.zero.

(random_seed) [HAVE_LRAND48]: Can be long int now. (init_random) [!WINDOWSNT]: Use getrandom syscall instead of opening /dev/urandom, as this works even on GNU/Linux hosts that lack /dev/urandom.
