Dmitry Petrov	84e54124a2	More aggressive DCE should honor debugger invariants ... - A LINENUMEBER node is "dead" if the corresponding instruction interval contains at least one "dead" bytecode instruction and no live bytecode instructions - Observable local variable lifetimes should be taken into account when determining if a NOP is required for debugger.	2017-05-16 17:28:43 +03:00
Dmitry Petrov	2051355d6a	Optimize constant conditions ... Using basic constant propagation (only integer constants, no arithmetic calculations), rewrite conditional jump instructions with constant arguments. This covers problem description in KT-17007. Note that it also works transparently with inline functions. Partial evaluation is required to cover more "advanced" cases. As a side effect, this also covers KT-3098: rewrite IF_ICMP<cmp_op>(x, 0) to IF<cmp0_op>(x).	2017-05-16 17:28:43 +03:00
