+"""Audit x86-64 ELF files against a CPU target's recorded compiler flags.
+
+The target is described by the flags GCC resolved -march=native into on that
+hardware, one per line, as in software-layer-scripts#311's references:
+``-mX`` for an extension the target has and ``-mno-X`` for one it lacks.
+Every executable section of every ELF file is decoded with iced-x86, and each
+instruction's CPUID features are compared with that list. An instruction
+whose feature the target lacks is a violation; a feature the list does not
+mention is reported as unclassified, never passed silently.
+
+    python isa_audit.py [--allow FILE] REFERENCE[,REFERENCE...] PATH [PATH ...]
+
+Several comma-separated references are checked in one decoding pass. PATH may
+be a file or a directory; a directory is walked for regular files that are
+executable or named like a shared object, the only files read. The exit
+status is 1 when there is any violation against the first reference.
+
+--allow FILE lists code that selects its instruction set at run time, one
+"PACKAGE feature[,feature...] [FUNCTION[,FUNCTION...]]  # reason" per line. A
+violation in a file under /software/PACKAGE/ on a listed feature is reported
+as DISPATCH, not counted as a failure; the dynamic chip check (SDE) covers
+what actually runs. When FUNCTION globs are given, only instructions inside a
+function whose symbol matches one of them are covered, so the same feature
+anywhere else in the package is still a violation.

+"""Audit aarch64 ELF files against a CPU target with llvm-objdump.
+
+Each file is disassembled twice: once with every feature llvm-objdump knows
+(its default for AArch64), and once restricted to the target. An instruction
+that decodes in the first and shows as <unknown> in the second needs a feature
+the target lacks: a violation.
+
+The target comes from a software-layer-scripts#311 reference, in either form:
+  clang:  "-target-cpu X" and "-target-feature +f" lines
+  gcc:    one "-mcpu=X+f+nof..." line
+
+    python isa_audit_aarch64.py [--allow FILE] REFERENCE PATH [PATH ...]
+
+llvm-objdump must be on PATH (LLVM 20 or later). Exit status 1 on violation.
+
+The helpers libgcc links for -moutline-atomics (__aarch64_ldadd8_acq_rel and
+friends) carry LSE instructions behind a check of HWCAP_ATOMICS, so
+instructions inside those functions pass by rule. In a stripped file the
+helpers have no names; they are recognised by their shape instead: the LSE
+instruction directly follows "ldrb w16, [__aarch64_have_lse_atomics]" and
+"cbz w16".
+
+Each violation is attributed to the LLVM feature that makes it decode when
+added to the target. --allow FILE takes the same "PACKAGE feature[,...]
+[FUNCTION[,...]]  # reason" lines as isa_audit.py, with LLVM feature names: a
+violation in a file under /software/PACKAGE/ on a listed feature, and inside a
+matching function when globs are given, is reported as DISPATCH.

+#
+# Check that the compilers of all toolchains supported in the current EESSI version translate the "native"
+# architecture flag (as used by EasyBuild) into *exactly* the same set of target flags on this build host as
+# recorded in a reference for the current CPU target (EESSI_SOFTWARE_SUBDIR).
+#
+# This guards against having multiple build hosts for the same CPU target that (subtly) differ in which
+# instruction set extensions the compilers detect, e.g. due to a different CPU stepping/SKU, different kernel
+# version (on aarch64, detection relies on hwcaps in /proc/cpuinfo), or CPU features being masked by a hypervisor.
+# If such hosts both build for the same CPU target, the result may be binaries that don't run on all
+# systems of that CPU target.
+#
+# Rather than checking the CPU flags reported by lscpu (or similar), we ask the compiler driver itself what it
+# resolves the native flag into, since that's what really matters. As this depends on the compiler version,
+# references are stored per CPU target, compiler and compiler version, in:
+#   <this directory>/references/<EESSI_SOFTWARE_SUBDIR>/<compiler>-<version>.txt
+#
+# For GCC, all -m* options passed by the driver to cc1 are taken into account (--param options like
+# l1-cache-size are not, since they only affect tuning, and are more likely to differ between CPUs of the same type).
+# For Clang, all -target-cpu, -tune-cpu, -target-abi and -target-feature options passed to clang -cc1 are taken
+# into account.
+#
+# Requires an initialised EESSI environment (EESSI module loaded) and Lmod's module command.
