simplify constraints after combining constraints from different sets
Sven Verdoolaege [Sun, 10 Aug 2008 12:18:07 +0000 (14:18 +0200)]
remove spurious ; from isl_assert definition
Sven Verdoolaege [Sun, 10 Aug 2008 10:19:33 +0000 (12:19 +0200)]
reimplement isl_basic_map_is_empty in terms of isl_basic_set_sample

isl_basic_map_set_to_empty: remove superfluous check
Sven Verdoolaege [Tue, 12 Aug 2008 10:36:50 +0000 (12:36 +0200)]
isl_basic_{map,set}: explicitly store constraints defining div
These constraints are redundant, but we need then while performing
various operations, so it is easier to keep them available explicitly.

avoid preprocessor conditionals

isl_basic_map_is_empty: special case known empty basic sets

remove remnants of old "primitive" naming

isl_map_subtract: simplify and finalize parts before checking emptiness

isl_basic_map_gauss: handle redundant or conflicting equalities directly

Fix typo in isl_map_affine_hull
Sven Verdoolaege [Sun, 17 Aug 2008 14:03:56 +0000 (16:03 +0200)]
Fix serious bug in normalize_constraints
We would mistakenly relax constraints to include extra integer
points rather than tightening them to remove some rational points.

Initial version of the integer set library
This version is very incomplete and unoptimized.
