A function added to this package ran as part of importing it and
printed a warning for most Spack invocations, this removes the
warning message.
Also:
* Use compilers directly instead of Spack compiler wrappers (since
references to the compiler are embedded in text and binary files
of the installation)
* Add 'cross' variant for setting CROSS environment variable for
build
* Set UPCXX_INSTALL for generated module files
* Set UPCXX_GASNET_CONDUIT/UPCXX_NETWORK in generated module files
on Cray systems
* Also set UPCXX_NETWORK in build environment for Cray systems

The output of subprocess.check_output is a byte string in Python 3. This causes dictionary lookup to fail later on.
A try-except around this function prevented this error from being noticed. Removed this so that more errors can propagate out.

Add newest release with ability to pre-build as shared or static
library.

Preferred targets were failing because we were looking them up by
Microarchitecture object, not by string.
- [x] Add a call to `str()` to fix target lookup.
- [x] Add a test to exercise this part of concretization.
- [x] Add documentation for setting `target` in `packages.yaml`

* microarchitectures: zen starts from x86_64, not from excavator
* Unit tests: fixed a test that is wrong with the new modeling
* microarchitectures: fixed features and inheritance for 15h family
bulldozer doesn't inherit from barcelona (10h) + added xop, lwp and tbm
instruction sets to the 15h family (it distinguish the family from 17h)
|

* Fix installation permissions on BLIS and libflame libs
* Fix undefined symbols

Also enable vectorization via -O3 for gcc/clang

Addresses #12804
This PR adds the creation of the remaining (16) templates to ensure we can create them with expected content. The goal is to facilitate catching during testing.

The 'fontconfig' option is only valid when freetype is enabled.

Spack doesn't need `requests`, and neither does `jsonschema`, but
`jsonschema` tries to import it, and it'll succeed if `requests` is on
your machine (which is likely, given how popular it is). This commit
removes the import to improve Spack's startup time a bit.
On a mac with SSD, the import of requests is ~28% of Spack's startup time
when run as `spack --print-shell-vars sh,modules` (.069 / .25 seconds),
which is what `setup-env.sh` runs.
On a Linux cluster where Python is mounted from NFS, this reduces
`setup-env.sh` source time from ~1s to .75s.
Note: This issue will be eliminated if we upgrade to a newer `jsonschema`
(we'd need to drop Python 2.6 for that). See
https://github.com/Julian/jsonschema/pull/388.

This PR adds the new --known-targets flag to the `spack arch` command.

- This is needed to support Cray machines -- we need an architecture
mic_knl > x86_64
- We used Cray's naming scheme for this target to make it work seamlessly
with the module-based detection sccheme on Cray. mic_knl is pretty
much dead, so this will be the last succh target. We will need to work
wtih Cray and other vendors in the future.

Seamless translation from 'target=<generic>' to either
- target.family == <generic> (in methods)
- 'target=<generic>:' (in directives)
Also updated docs to show ranges in directives.

Spack can now:
- label ppc64, ppc64le, x86_64, etc. builds with specific
microarchitecture-specific names, like 'haswell', 'skylake' or
'icelake'.
- detect the host architecture of a machine from /proc/cpuinfo or similar
tools.
- Understand which microarchitectures are compatible with which (for
binary reuse)
- Understand which compiler flags are needed (for GCC, so far) to build
binaries for particular microarchitectures.
All of this is managed through a JSON file (microarchitectures.json) that
contains detailed auto-detection, compiler flag, and compatibility
information for specific microarchitecture targets. The `llnl.util.cpu`
module implements a library that allows detection and comparison of
microarchitectures based on the data in this file.
The `target` part of Spack specs is now essentially a Microarchitecture
object, and Specs' targets can be compared for compatibility as well.
This allows us to label optimized binary packages at a granularity that
enables them to be reused on compatible machines. Previously, we only
knew that a package was built for x86_64, NOT which x86_64 machines it
was usable on.
Currently this feature supports Intel, Power, and AMD chips. Support for
ARM is forthcoming.
Specifics:
- Add microarchitectures.json with descriptions of architectures
- Relaxed semantic of compiler's "target" attribute. Before this change
the semantic to check if a compiler could be viable for a given target
was exact match. This made sense as the finest granularity of targets
was architecture families. As now we can target micro-architectures,
this commit changes the semantic by interpreting as the architecture
family what is stored in the compiler's "target" attribute. A compiler
is then a viable choice if the target being concretized belongs to the
same family. Similarly when a new compiler is detected the architecture
family is stored in the "target" attribute.
- Make Spack's `cc` compiler wrapper inject target-specific flags on the
command line
- Architecture concretization updated to use the same algorithm as
compiler concretization
- Micro-architecture features, vendor, generation etc. are included in
the package hash. Generic architectures, such as x86_64 or ppc64, are
still dumped using the name only.
- If the compiler for a target is not supported exit with an intelligible
error message. If the compiler support is unknown don't try to use
optimization flags.
- Support and define feature aliases (e.g., sse3 -> ssse3) in
microarchitectures.json and on Microarchitecture objects. Feature
aliases are defined in targets.json and map a name (the "alias") to a
list of rules that must be met for the test to be successful. The rules
that are available can be extended later using a decorator.
- Implement subset semantics for comparing microarchitectures (treat
microarchitectures as a partial order, i.e. (a < b), (a == b) and (b <
a) can all be false.
- Implement logic to automatically demote the default target if the
compiler being used is too old to optimize for it. Updated docs to make
this behavior explicit. This avoids surprising the user if the default
compiler is older than the host architecture.
This commit adds unit tests to verify the semantics of target ranges and
target lists in constraints. The implementation to allow target ranges
and lists is minimal and doesn't add any new type. A more careful
refactor that takes into account the type system might be due later.

Add llnl.util.cpu_name, with initial support for detecting different
microarchitectures on Linux. This also adds preliminary changes for
compiler support and variants to control the optimizatoin levels by
target.
This does not yet include translations of targets to particular
compilers; that is left to another PR.

use machotools on linux. (#12867)
Move verbose messages to debug level
get_patchelf should return None for test platform as well because create_buildinfo invokes patchelf to get rpaths.
