In preparation for the deprecation of `stdenv.isX`. These shorthands are not conducive to cross-compilation because they hide the platforms. Darwin might get cross-compilation for which the continued usage of `stdenv.isDarwin` will get in the way One example of why this is bad and especially affects compiler packages https://www.github.com/NixOS/nixpkgs/pull/343059 There are too many files to go through manually but a treewide should get users thinking when they see a `hostPlatform.isX` in a place where it doesn't make sense. ``` fd --type f "\.nix" | xargs sd --fixed-strings "stdenv.is" "stdenv.hostPlatform.is" fd --type f "\.nix" | xargs sd --fixed-strings "stdenv'.is" "stdenv'.hostPlatform.is" fd --type f "\.nix" | xargs sd --fixed-strings "clangStdenv.is" "clangStdenv.hostPlatform.is" fd --type f "\.nix" | xargs sd --fixed-strings "gccStdenv.is" "gccStdenv.hostPlatform.is" fd --type f "\.nix" | xargs sd --fixed-strings "stdenvNoCC.is" "stdenvNoCC.hostPlatform.is" fd --type f "\.nix" | xargs sd --fixed-strings "inherit (stdenv) is" "inherit (stdenv.hostPlatform) is" fd --type f "\.nix" | xargs sd --fixed-strings "buildStdenv.is" "buildStdenv.hostPlatform.is" fd --type f "\.nix" | xargs sd --fixed-strings "effectiveStdenv.is" "effectiveStdenv.hostPlatform.is" fd --type f "\.nix" | xargs sd --fixed-strings "originalStdenv.is" "originalStdenv.hostPlatform.is" ```

|
|
The Parma Polyhedra Library (PPL) provides numerical abstractions
|
|
especially targeted at applications in the field of analysis and
|
|
verification of complex systems. These abstractions include convex
|
|
polyhedra, defined as the intersection of a finite number of (open or
|
|
closed) halfspaces, each described by a linear inequality (strict or
|
|
non-strict) with rational coefficients; some special classes of
|
|
polyhedra shapes that offer interesting complexity/precision tradeoffs;
|
|
and grids which represent regularly spaced points that satisfy a set of
|
|
linear congruence relations. The library also supports finite
|
|
powersets and products of (any kind of) polyhedra and grids and a mixed
|
|
integer linear programming problem solver using an exact-arithmetic
|
|
version of the simplex algorithm.
