* * mpi-patches/fix-mult-bug: One more flaw discovered inKaz Kylheku2011-12-121-0/+1
| | | | | | | | | | | | s_mp_mul_d and added to patch. This one caused malloc corruption and crashes, because the incorrect arithmetic causes the function to think that the multiplication will not be needing another digit, but then there is a carry out which does spill into a new digit. * mpi-patches/series: Arg! Somehow the patch fix-bad-shift went missing from the series file, even though the patch itself is in the GIT repository.
* * mpi-patches/mpi-set-mpi-word: Bugfix and refresh.Kaz Kylheku2011-12-101-0/+1

* Adding mp_set_word function.Kaz Kylheku2011-12-101-0/+1
| | | | | | * mpi-patches/series (mpi-set-mpi-word): New patch. * mpi-patches/mpi-set-mpi-word: New file.
* Bignum support, here we go!Kaz Kylheku2011-12-091-0/+8
Bignums, based on Michael Fromberger's MPI library, are integrated into the input syntax, stream output, equality testing, the garbage collector, and hashing. The plus operation handles transitions between fixnums and bignums. Other operations are still fixnum only. * Makefile (CFLAGS): Add mpi directory to include file search. (OBJS): Include new arith.o module and all of MPI_OBJS. (MPI_OBJS, MPI_OBJS_BASE): New variables. * configure (mpi_version, have_quilt, have_patch): New variables. Script detects whether patch and quilt are available. Unpacks mpi library, applies patches. Detects 128 bit integer type. Records more information in config.h about the sizes of types. * dep.mk: Updated. * depend.txr: Make work with paths that have directory components. * eval.c (eval_init): Rename of nump to fixnump. * gc.c (finalize, mark_obj): Handle BGNUM case. * hash.c: (hash_c_str): Changed to return unsigned long instead of long. (equal_hash): Handle BGNUM case. (eql_hash): Handle bignums with equal-hash, but other objects as eq. * lib.c (num_s): Variable renamed to fixnum_s. (bignum_s): New symbol variable. (code2type): Follow rename of num_s. Handle BGNUM case. (typeof): Follow rename of num_s. (eql): Handle bignums using equal, and other types using eq. (equal): Handle BGNUM case. (chk_calloc): New function. (c_num): Wording change in error message: is not a fixnum. (nump): Renamed to fixnump. (bignump): New function. (plus): Function removed, reimplemented in arith.c. (int_str): Handle integers which are too large for wcstol using bignum conversion. Base 0 is no longer passed to wcstol but converted to 10 because the special semantics for 0 would be inconsistent for bignums. (obj_init): Follow rename of num_s. Initialize bignum_s.
