=head1 NAME
-README.aix - Perl version 5.13.4 on IBM AIX (UNIX) systems
+perlaix - Perl version 5 on IBM AIX (UNIX) systems
=head1 DESCRIPTION
This will not build a threaded Perl, but a thread-enabled Perl. See
also L<Threaded Perl> later on.
-As of writing (2010-05) only the I<IBM XL C for AIX> or I<IBM XL C/C++
-for AIX> compiler is supported by IBM on AIX 5L/6.1.
+As of writing (2010-09) only the I<IBM XL C for AIX> or I<IBM XL C/C++
+for AIX> compiler is supported by IBM on AIX 5L/6.1/7.1.
The following compiler versions are currently supported by IBM:
- IBM XL C and IBM XL C/C++ V8, V9, V10
+ IBM XL C and IBM XL C/C++ V8, V9, V10, V11
The XL C for AIX is integrated in the XL C/C++ for AIX compiler and
therefore also supported.
The PTF for APAR IZ35785 which solves this problem is available
from IBM (April 2009 PTF for XL C/C++ Enterprise Edition for AIX, V9.0).
-If you choose XL C/C++ V11 you need the April 2010 PTF installed
-otherwise you will not get a working Perl version.
+If you choose XL C/C++ V11 you need the April 2010 PTF (or newer)
+installed otherwise you will not get a working Perl version.
Perl can be compiled with either IBM's ANSI C compiler or with gcc.
The former is recommended, as not only it can compile Perl with no
detected. If you want to build Perl with GDBM support then please install
at least gdbm-devel-1.8.3-5 (or higher).

The -1 removes this limit. If the "make test" fails please change
your /etc/security/limits as stated above.
-=head2 Recommended Options AIX 5.1/5.2/5.3 and 6.1 (threaded/32-bit)
+=head2 Long doubles
+
+IBM calls its implementation of long doubles 128-bit, but it is not
+the IEEE 128-bit ("quadruple precision") which would give 116 bit of
+mantissa (nor it is implemented in hardware), instead it's a special
+software implementation called "double-double", which gives 106 bits
+of mantissa.
+
+There seem to be various problems in this long double implementation.
+If Configure detects this brokenness, it will disable the long double support.
+This can be overriden with explicit C<-Duselongdouble> (or C<-Dusemorebits>,
+which enables both long doubles and 64 bit integers). If you decide to
+enable long doubles, for most of the broken things Perl has implemented
+workarounds, but the handling of the special values infinity and NaN
+remains badly broken: for example infinity plus zero results in NaN.
+

+=head2 Compiling Perl 5 on AIX 7.1.0
+
+A regression in AIX 7 causes a failure in make test in Time::Piece during
+daylight savings time. APAR IV16514 provides the fix for this. A quick
+test to see if it's required, assuming it is currently daylight savings
+in Eastern Time, would be to run C< TZ=EST5 date +%Z >. This will come
+back with C<EST> normally, but nothing if you have the problem.
+

=head2 Compiling Perl 5 on older AIX versions up to 4.3.3

cumulative.
