* Modify Flang NVidia GPU variant to make use of built-in CudaPackage
* Add OpenMP Offload patch if March 2019 compiler is selected.
* Flang parallel build has a race condition.
* llvm-flang now uses built-in CudaPackage.
* Add variant for different build releases.
* Fix OpenMP target offload for NVidia GPUs.
* Additional commong flags that are needed with comments.
* NVidia BC required for libomp target requires special treatment. Use clang built in previous step to re-compile libomptarget.
* Add 20181226 release of pgmath
* 20190329 release of pgmath requires match for CMPLX macro.
* Add llvm-flang package for Flang fork of LLVM
* Add new and old flang releases.
* Add cmake and python dependencies.
* Update dependencies on llvm-flang and pgmath.
* Fix cmake args and change spec to reflect llvm-flang package.
* change copyright date through 2020.
* Reference Flang package more explicitly.
* More robust support for python executable.
* import os no longer needed, picked up by flake8.
* Use built-in target spec. Variant and targets follow style in main LLVM package.
* Get rid of targets list and only support one target for now.
* Sparc does not appear to be supported in Flang.
* Raise InstallError if architecture not supported.
We'd like to use a consistent checksum scheme everywhere so that we can:
a) incorporate archive checksums into our specs and have a
consistent hashing algorithm across all specs.
b) index mirrors with a consistent type of checksum, and not one that
is dependent on how spack packages are written.
- [x] convert existing md5, sha224, sha512, sha1 checksums to sha256
Seamless translation from 'target=<generic>' to either
- target.family == <generic> (in methods)
- 'target=<generic>:' (in directives)
Also updated docs to show ranges in directives.
- remove the old LGPL license headers from all files in Spack
- add SPDX headers to all files
- core and most packages are (Apache-2.0 OR MIT)
- a very small number of remaining packages are LGPL-2.1-only
Flang now uses its own version of llvm and clang (called flang-driver). This is
handled by adding flang-specific versions of the LLVM package and updates flang
to depend on those versions.
