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. + (obj_print, obj_pprint): Handle BGNUM. + (init): Call arith_init. + + * lib.h: Includes "mpi.h", as an exception to the project rule against + headers including headers. + (enum type): New enumeration member, BGNUM. + (struct bignum): New struct type. + (union obj): New member bn. + (mp): New inline function. + (num_s): Redeclared as fixnum_s. + (bignum_s, chk_calloc, bignump): Declared. + (nump): Redeclared as fixnump. + + * match.c (h_var, h_line, h_skip, h_coll, h_fun, format_field, v_skip, + v_freeform, v_collect, v_match_files): Follow nump to fixnump rename. + + * parser.l (NUM): New token type. Split up the parsing of identifiers + and numbers once again. But since every number is also lexically also + lexically an identifier, we put the action first. The action for + making numbers handles bignums. It produces object numbers, not + C numbers (change in yystype union). + + * parser.y (%union): num changes type from cnum to val. + + * stream.c (vformat): Handle bignums in numeric conversions. + + * arith.c: New file. + + * arith.h: New file. + + * mpi-1.8.6.tar.gz: New file. + + * mpi-patches/add-mp-hash: New file. + + * mpi-patches/add-mp-set-intptr: New file. + + * mpi-patches/add-mpi-toradix-with-case: New file. + + * mpi-patches/config-types: New file. + + * mpi-patches/export-mp-eq: New file. + + * mpi-patches/fix-mult-bug: New file. + + * mpi-patches/fix-warnings: New file. + + * mpi-patches/series: New file. + + * mpi-patches/use-txr-allocator: New file. + 2011-12-08 Kaz Kylheku <kaz@kylheku.com> C++ maintenance. |
