whitequark 211af77e77 validators.escape: cache_get result lives forever. 2016-01-10 14:43:21 +00:00
whitequark 9ed6b54249 transforms.cfg_simplifier: remove.
Specifically, the following idiom broke our CFGSimplifier:

b1:
  branch_if %cond, %b2, %b3
b2:
  branch %b3
b3:
  %v = phi [ %b2 => 0, %b3 => 1 ]

This is very annoying to properly handle in general case, and also
this (specifically %b2) is exactly what broke LocalAccessValidator
in the first place. So, remove CFGSimplifier altogether.

Instead, teach LocalAccessValidator how to look through predecessors
in order to get a location.

whitequark a557445e05 LocalAccessValidator: assume variables with "$" in name are internal.
Internal variables are assumed to be scoped correctly
(including not being accessed uninitialized).

This was changed from "." because artiq.compiler.embedding uses
"." in module prefix of function names.

whitequark bfabca494b Remove regions from types.
Unification-based inference for regions is useful with a language
that has let bindings (which would propagate the regions) and
functions polymorphic over regions. For reasons of simplicity,
ARTIQ has neither, and making unification-based inference work would
essentially mean adding region coercions between most AST nodes,
and having every source subexpression have its own region variable,
with the appropriate subtyping relationship.

It's simpler to just keep that state outside of typedtree.
