whitequark 4e7493843a compiler: Constness is a validator, not analysis. 2017-06-09 07:29:31 +00:00
whitequark 5d841d08e9 compiler: do not permit mutation of bytes values (#714). 2017-06-09 07:29:28 +00:00
whitequark 3a1f14c16c compiler: fix overly strict constness analysis. 
Before this commit, the following code would fail to compile...
  obj.foo.bar = True
... if foo is marked kernel_invariant in obj, even if bar is not
marked as such in obj.foo.

whitequark 53b7d59b6a analyses.constness: fix false positive on x[...]. 2016-11-21 14:20:26 +00:00
whitequark f5cca6b09e analyses.invariant_detection: implement (#622). 2016-11-20 12:48:26 +00:00
whitequark f4e6b18690 compiler: implement kernel constant attributes. 
Part of #322.

whitequark 5f0e2bf9f9 analyses.domination: all blocks dominate themselves. 2016-01-18 21:33:14 +00:00
whitequark dfbf55fed2 transforms/inferencer: add support for user-defined context manager. 2016-01-05 00:11:03 +08:00
whitequark 3fbee2707b analyses.domination: consider unreachable blocks dominated by any other. 
As a result, the dominator tree can now process arbitrary (reducible)
CFGs and we do not run DCE before analyses, risking loss of
correspondence to the AST, which would arbitrarily silence analyses.

whitequark f8eaeaa43f compiler: explicitly represent loops in IR. 2015-12-16 15:33:26 +08:00
whitequark 9670939ca6 compiler.analyses.domination: fix PostDominatorTree. 2015-11-09 12:49:27 +03:00
whitequark 19fae9181c compiler.analyses.domination: implement new dominator tree algorithm. 2015-11-09 11:51:54 +03:00
whitequark 3a1b77ae6b analyses.domination: add PostDominatorTree. 2015-11-01 09:49:39 +03:00
whitequark 6922bd5638 analyses.devirtualization: look up functions in outer scopes. 2015-10-09 01:32:05 +03:00
whitequark 7043b333a7 transforms.devirtualizer → analyses.devirtualization. 2015-10-09 00:29:31 +03:00
whitequark f212ec0263 Add a trivial dead code elimination transform. 
Its purpose is to sweep up basic blocks with no predecessors,
which are annoying to handle explicitly elsewhere.

whitequark 603d49dffa Add a dominator analysis. 2015-07-18 20:48:52 +03:00
