+This package ensures that the machine has required CPU facilities; users who
+attempt installation on an inadequate processor will receive an error message
+in preinst. This is useful if there's no way to make your package support
+the base ISA for the architecture.
+
+While in general packages are required to at least try, there are situations
+when baseline support is infeasible or a pure waste of time. No one is
+going to run scientific number-crunching software on a pre-SSE2/SSE3
+machine. Or upstream code may use such extensions unconditionally, and
+you don't have the resources to fix that yourself.
+
+You should also consider how likely other software is to use your package.
+A fast strong hash is something with many uses, big and small, so it's a
+priority to port libraries like libhighwayhash to all CPUs. On the other
+hand, a niche piece of software is unlikely to be repurposed for other uses.
+
+
+The check is skipped in two cases:
+* when the target architecture is not executable at all (an ARM SoC mounted
+ into an amd64 machine, etc)
+* when ISA_IGNORE environment variable has a non-empty value

+qemu-bad: qemu-$DEB_HOST_ARCH -cpu "qemu$DEB_HOST_ARCH_BITS",-see2,-sse3,-ssse3,-sse4.1,-sse4.2
+Description:
+ Streaming SIMD Extensions (SSE) is a single instruction, multiple data
+ (SIMD) instruction set extension.
+ .
+ SSE2 was an incremental upgrade to SSE intended to fully replace the earlier
+ MMX instruction set. It is available on processors from Pentium 4 onward,
+ including all 64-bit capable ones, but not on Pentium 3, Athlon XP, Via C3,
+ Quark, or older processors.

+Description:
+ Streaming SIMD Extensions (SSE) is a single instruction, multiple data
+ (SIMD) instruction set extension.
+ .
+ SSE3, also called PNI (Prescott New Instructions), is an incremental upgrade
+ to SSE2, adding a handful of new operations useful for processing media. It
+ is available on almost any 64-bit-capable processor except for some early
+ AMD models (Sledgehammer and Clawhammer), but is not available on most
+ 32-bit-only hardware.

+Description:
+ Streaming SIMD Extensions (SSE) is a single instruction, multiple data

+ .
+ SSE4.1 added a dot product instruction and additional integer instructions.
+ It is available on Intel processors since Penryn (circa 2008), but notably
+ not on anything AMD until the Bulldozer (15h, in 2011) and Jaguar (16h, in
+ 2013) families.

+Description:
+ AltiVec is a single-precision floating point and integer SIMD instruction
+ set. It is a standard part of the Power ISA v.2.03 specification.
+# gcc-16 has __builtin_cpu_supports("altivec") but it's not reliable: silently
+# gives wrong answer on qemu, wrong versions of glibc, non-glibc, etc.
+# Thus, let's use SIGILL instead.
+
+Name: neon
+Architecture: armhf
+CFLAGS: -mfpu=neon
+Test: asm volatile("VMUL.I16 q0,q0,q1");
+Description:
+ This is a mostly dummy package which checks for Neon and refuses to install
+ on unsupported hardware.
+ .
+ Neon, also known as MPE (Media Processing Engine) or Advanced SIMD, is a
+ combined 64- and 128-bit SIMD instruction set that provides standardised
+ acceleration for media and signal processing applications. It is available
+ on the vast majority of armhf devices but not guaranteed before the 64-bit
+ capable ARMv8.
+
+Name: ARMv6
+Architecture: armel
+Test: return !need_armv_version(6);
+Description:
+ The ARMv6 architecture (not to be confused with product family ARM6) uses
+ physically addressed cache, solving many cache aliasing problems and
+ reducing context switch overhead. Unaligned and mixed-endian data access is
+ supported. This architecture includes the first version of Thumb
+ technology.
+ .
+ This feature is not guaranteed by the architecture baseline, but is
+ available for newer armel machines in the ARM11 product family, including
+ ARM1136J(F)-S, ARM1156T2(F)-S, ARM1176JZ(F)-S, ARM1136EJ(F)-S, and
+ ARM11MPCore processors. Boards include the Raspberry Pi model 1 and
+ Raspberry Pi Zero.
+
+Name: ARMv6K
+Architecture: armel
+Test: return !(need_armv_version(6) && (getauxval(AT_HWCAP) & HWCAP_ARM_TLS));
+Description:
+ ARMv6k is a subarchitecture of ARMV6 adding Symmetric MultiProcessing
+ and Thread Local Storage instruction sets. It is not guaranteed by the
+ architecture baseline, but is available for newer armel machines in the
+ ARM11 product family; boards include the Raspberry Pi model 1 and
+ Raspberry Pi Zero.
+
+Name: ARMv7
+Architecture: armel
+Test: return !need_armv_version(7);
+Description:
+ ARMv7 (not to be confused with product family ARM7) includes Thumb-2
+ technology, adding 32-bit instructions into compressed Thumb mode. It is
+ not guaranteed by the architecture baseline, but is available for newer
+ armel machines (including CPUs that support armhf) since the Cortex-A
+ product family, including Cortex-A5, -A7, -A8, -A9, -A12, -A15, and -A17
+ processors. Boards include the Raspberry Pi 2.
+
+Name: ARMv8
+Architecture: armel armhf
+Test: return !need_armv_version(8);
+Description:
+ ARMv8 (not to be confused with product family ARM8) introduced a large
+ number of ISA enhancements. It is not guaranteed by the architecture
+ baseline, but is available for newer armel machines (including CPUs that
+ support armhf) since the Cortex-A product family, including Cortex-A32, as
+ well as all arm64 processors. Boards include the Raspberry Pi 3 and 4.
+
+Name: VFP
+Architecture: armel
+Test: return !(getauxval(AT_HWCAP) & HWCAP_ARM_VFP)
+Description:
+ VFP (Vector Floating Point) technology is a floating-point unit (FPU)
+ coprocessor extension to the ARM architecture. It provides single- and
+ double-precision floating-point computation fully compliant with IEEE
+ 754-1985.

+Test: return !(getauxval(AT_HWCAP) & HWCAP_ARM_VFPv3)
+Description:
+ VFP (Vector Floating Point) technology is a floating-point unit (FPU)
+ coprocessor extension to the ARM architecture. It provides single- and
+ double-precision floating-point computation fully compliant with IEEE
+ 754-1985.
+ .
+ VFPv3 has 32 64-bit FPU registers as standard, adds VCVT instructions to
+ convert between scalar, float, and double, and adds immediate mode to VMOV,
+ allowing constants to be loaded into FPU registers. It is available on most
+ Cortex-A8 and -A9 ARMv7 processors.
