Depends: ${shlibs:Depends}, ${misc:Depends}
Description: test for architecture features
The isa-support package contains test programs that probe for architecture
features like SSE3. Other packages can use these to prevent installation on
machines that lack these features. For convenience, there are individual
packages for each feature that other packages can pre-depend on:
.
sse2-support, sse3-support, sse4.2-support, altivec-support, neon-support,
armv6-support, armv7-support, armv8-support, vfp-support, vfpv2-support,
vfpv3-support
Package: sse2-support

Architecture: any-i386
Pre-Depends: isa-support (= ${binary:Version})
Description: prevent installation on processors without required sse2 instructions
This is a mostly dummy package, whose only purpose is to detect the presence
of sse2. It refuses to install on inadequate processors, thus allowing
specifying such a requirement as a dependency.
.

multiple data (SIMD) instruction set extension.
.
These instructions are available on processors from Pentium 4 onward,
including any 64-bit capable. There's no SSE2 on Pentium 3, Athlon XP,
Via C3, Quark -- and older.

2008), but notably not on anything AMD until 2011-13, starting with family
15h (Bulldozer then Jaguar).

several new instructions that perform character searches
and comparison on two operands of 16 bytes at a time.
.

2008), but notably not on anything AMD until 2011-13, starting with family
15h (Bulldozer then Jaguar).
