prompt: We are currently solving the following issue within our repository. Here is the issue text:
  --- BEGIN ISSUE ---
  Invalid flag with apple m2 cpu and apple-clang (clang-1400.0.29.202)
  On a system as described in the title, the following flag in not recognized and causes compilation failures:
  
  https://github.com/spack/spack/blob/b2c806f6fcd73ae624582c84a177e465a7877cf7/lib/spack/external/archspec/json/cpu/microarchitectures.json#L2794
  
  Replacing with `-mcpu=apple-m1` seems to fix the issue. There seems to be no flag specific to m2 cpu.

  8 
  9 altgraph
  10 --------
  11 
  12 * Homepage: https://altgraph.readthedocs.io/en/latest/index.html
  13 * Usage: dependency of macholib
  14 * Version: 0.17.3
  15 
  16 archspec
  17 --------
  18 
  19 * Homepage: https://pypi.python.org/pypi/archspec
  20 * Usage: Labeling, comparison and detection of microarchitectures
  21 * Version: 0.2.0 (commit e44bad9c7b6defac73696f64078b2fe634719b62)
  22 
  23 astunparse
  24 ----------------
  25 
  26 * Homepage: https://github.com/simonpercivall/astunparse
  27 * Usage: Unparsing Python ASTs for package hashes in Spack
  28 * Version: 1.6.3 (plus modifications)
  29 * Note: This is in ``spack.util.unparse`` because it's very heavily
  30   modified, and we want to track coverage for it.
  31   Specifically, we have modified this library to generate consistent unparsed ASTs
  32   regardless of the Python version. It is based on:
  33     1. The original ``astunparse`` library;
  34     2. Modifications for consistency;
  35     3. Backports from the ``ast.unparse`` function in Python 3.9 and later
  36   The unparsing is now mostly consistent with upstream ``ast.unparse``, so if
  37   we ever require Python 3.9 or higher, we can drop this external package.
  38 
  39 attrs
  40 ----------------
  41 
  42 * Homepage: https://github.com/python-attrs/attrs
  43 * Usage: Needed by jsonschema.

  90 pyrsistent
  91 ----------
  92 
  93 * Homepage: http://github.com/tobgu/pyrsistent/
  94 * Usage: Needed by `jsonschema`

  97 ruamel.yaml
  98 ------
  99 
  100 * Homepage: https://yaml.readthedocs.io/

  102   actively maintained and has more features, including round-tripping
  103   comments read from config files.
  104 * Version: 0.11.15 (last version supporting Python 2.6)
  105 * Note: This package has been slightly modified to improve Python 2.6
  106   compatibility -- some ``{}`` format strings were replaced, and the
  107   import for ``OrderedDict`` was tweaked.

It is based on:\n    1. The original ``astunparse`` library;\n    2. Modifications for consistency;\n    3. Backports from the ``ast.unparse`` function in Python 3.9 and later\n  The unparsing is now mostly consistent with upstream ``ast.unparse``, so if\n  we ever require Python 3.9 or higher, we can drop this external package.\n\nattrs\n----------------\n\n* Homepage: https://github.com/python-attrs/attrs\n* Usage: Needed by jsonschema.\n* Version: 22.1.0\n\nctest_log_parser\n----------------\n\n* Homepage: https://github.com/Kitware/CMake/blob/master/Source/CTest/cmCTestBuildHandler.cxx\n* Usage: Functions to parse build logs and extract error messages.\n* Version: Unversioned\n* Note: This is a homemade port of Kitware's CTest build handler.\n\ndistro\n------\n\n* Homepage: https://pypi.python.org/pypi/distro\n* Usage: Provides a more stable linux distribution detection.\n* Version: 1.8.0\n\njinja2\n------\n\n* Homepage: https://pypi.python.org/pypi/Jinja2\n* Usage: A modern and designer-friendly templating language for Python.\n* Version: 3.0.3 (last version supporting Python 3.6)\n\njsonschema\n----------\n\n* Homepage: https://pypi.python.org/pypi/jsonschema\n* Usage: An implementation of JSON Schema for Python.\n* Version: 3.2.0 (last version before 2.7 and 3.6 support was dropped)\n* Note: We don't include tests or benchmarks; just what Spack needs.\n\nmacholib\n--------\n\n* Homepage: https://macholib.readthedocs.io/en/latest/index.html#\n* Usage: Manipulation of Mach-o binaries for relocating macOS buildcaches on Linux\n* Version: 1.16.2\n\nmarkupsafe\n----------\n\n* Homepage: https://pypi.python.org/pypi/MarkupSafe\n* Usage: Implements a XML/HTML/XHTML Markup safe string for Python.\n* Version: 2.0.1 (last version supporting Python 3.6)\n\npyrsistent\n----------\n\n* Homepage: http://github.com/tobgu/pyrsistent/\n* Usage: Needed by `jsonschema`\n* Version: 0.18.0\n\nruamel.yaml\n------\n\n* Homepage: https://yaml.readthedocs.io/\n* Usage: Used for config files. Ruamel is based on PyYAML but is more\n  actively maintained and has more features, including round-tripping\n  comments read from config files.\n* Version: 0.11.15 (last version supporting Python 2.6)\n* Note: This package has been slightly modified to improve Python 2.6\n  compatibility -- some ``{}`` format strings were replaced, and the\n  import for ``OrderedDict`` was tweaked.\n\nsix\n---\n\n* Homepage: https://pypi.python.org/pypi/six\n* Usage: Python 2 and 3 compatibility utilities.\n* Version: 1.16.0\n\n\"\"\"\n", "path": "lib/spack/external/__init__.py"}]}
