+Subject: [PATCH 1/8] Avoid c99 standard compiler
+
+When probing for a usable GCC, the existing code already dropped path
+names that contained "c89" or "c90", because these compilers don't have
+the GCC extensions enabled.  This patch also drops names with "c99" in
+them.

+Subject: [PATCH 3/8] Fix SIMD support on IBM z13
+
+The header file atlas_simd.h contained a syntax error and a few functional
+errors that affected IBM z13.  It prevented any SIMD kernels from being
+compiled successfully for that platform.  This is fixed.  The macro
+vec_madd is avoided, because some GCC versions don't implement it
+correctly; the equivalent GCC builtin __builtin_s390_vec_madd is used
+instead.

+Subject: [PATCH 4/8] Read L1 data cache size from sysconf if possible
+
+The probing of the L1 data cache size is sometimes not reliable.  This can
+cause the tuning to yield varying, sub-obtimal results.  But on Linux the
+L1 data cache size can usually be retrieved with sysconf instead, which is
+faster and more reliable.  Do this whenever possible.

+Date: Wed, 29 May 2019 17:51:34 +0200
+Subject: [PATCH 7/8] Enable "cross-compile"
+
+This adds support for building ATLAS without running any target code.  In
+order for this to work, the archdefs must contain some additional files
+that would otherwise be built during various tuning steps; see the new
+targets extra_get and extra_put in "CONFIG/ARCHS/Makefile".
+
+Even if the archdefs contain these additional files, cross compilation
+is *not* automatically enabled.  To activate it and disable tuning at
+build time, add the option "-Si archdef 2" when running "configure".

+Notes on the packaged version of ATLAS
+
+by Quentin Spencer
+updated: October 4, 2005
+
+updated by Deji Akingunola

+
+Because ATLAS relies on compile-time optimizations to obtain improved
+performance over BLAS and LAPACK, the resulting binaries are closely
+tied to the hardware on which they are compiled, and can likely result
+in very poor performance on other hardware.  For this reason,
+including a package like ATLAS in Fedora requires some compromises.
+Optimizing ATLAS for the most modern hardware can result in
+significant performance penalties for users using the same package on
+older hardware. A binary ATLAS package must perform reasonably well on the
+entire range of hardware on which it could potentially be installed.
+
+The result is a set of libraries that will not
+necessarily achieve optimal performance on any given hardware but
+should still offer significant performance gains over the reference
+BLAS and LAPACK libraries on most hardware.  
+
+In addition to the base 32bit build, subpackages are built for SSE, SSE2,
+and SSE3 ix86 extensions.
+
+On 64bit x86 systems the default atlas package was built with SSE3
+optimization.
+  
+This packaging allows multiple installation of different atlas sub-packages
+at the same time. The alternatives system (read 'man alternatives' for usage)
+is used in the -devel subpackages to select the appropriate location for the 
+architectural dependent header files.
+ 
+For users who want optimal performance on
+particular hardware, custom RPMs can be built from the source package
+by setting the RPM macro "enable_native_atlas" to a value of 1. This
+can be done from the command line as in the following example:
+
+rpmbuild -D "enable_native_atlas 1" --rebuild atlas-3.8.3-1.src.rpm
