<h1>1 HiPE Release Notes</h1>
<p>This document describes the changes made to HiPE.</p>
<h3><a name="id2255895">1.1
Hipe 3.7.5</a></h3>
<h4>Improvements and New Features</h4>
<ul>
<li>
<p>The documentation is now possible to build in an open
source environment after a number of bugs are fixed and
some features are added in the documentation build
process. </p>
<p>- The arity calculation is updated.</p>
<p>- The module prefix used in the function names for
bif's are removed in the generated links so the links
will look like
"http://www.erlang.org/doc/man/erlang.html#append_element-2"
instead of
"http://www.erlang.org/doc/man/erlang.html#erlang:append_element-2".</p>
<p>- Enhanced the menu positioning in the html
documentation when a new page is loaded.</p>
<p>- A number of corrections in the generation of man
pages (thanks to Sergei Golovan)</p>
<p>- The legal notice is taken from the xml book file so
OTP's build process can be used for non OTP
applications.</p>

<h3><a name="id2258178">1.2
Hipe 3.7.4</a></h3>
<h4>Improvements and New Features</h4>
<ul>
<li>
<p>
The documentation is now built with open source tools
(xsltproc and fop) that exists on most platforms. One
visible change is that the frames are removed.</p>

<h3><a name="id2259470">1.5

<h4>Improvements and New Features</h4>

</ul>
<h3><a name="id2259530">1.7
Hipe 3.6.9</a></h3>
<h4>Improvements and New Features</h4>
<ul>
<li>
<p>The <span class="code">--disable-hipe</span> option for the
<span class="code">configure</span> will now completely disable the hipe
run-time in the emulator, as is the expected
behaviour.</p>
<p>

<h3><a name="id2253488">1.9

<h4>Improvements and New Features</h4>
<ul>

<p>
Minor changes.</p>
<p>
Own Id: OTP-7388</p>
</li>
</ul>
<h3><a name="id2253518">1.10
Hipe 3.6.6</a></h3>
<h4>Fixed Bugs and Malfunctions</h4>
<ul>
<li>
<p>A fix for an #include problem which caused the FP
exception test to fail unnecessarily on
debian/glibc-2.7/x86 systems.</p>
<p>Added SIGFPE loop detection to the FP exception test.
This prevents the test from looping indefinitely, which
could happen when the CPU is supported (so we can enable
FP exceptions on it) but the OS isn't (so we can't write
a proper SIGFPE handler). x86 on an unsupported OS is
known to have had this problem.</p>
<p>
Own Id: OTP-7254</p>
</li>
</ul>
<h4>Improvements and New Features</h4>
<ul>
<li>
<p>
HiPE now also supports little-endian ARM processors.</p>

Own Id: OTP-7255</p>
</li>
</ul>
<h3><a name="id2253584">1.11
Hipe 3.6.5</a></h3>
<h4>Fixed Bugs and Malfunctions</h4>
<ul>
<li>
<p>
HIPE: Corrected the choice of interface to the send/3 and
setnode/3 BIFs for native-compiled code. Using the
incorrect interface could, in unusual circumstances, lead
to random runtime errors.</p>
<p>
Own Id: OTP-7067</p>
</li>
</ul>
<h4>Improvements and New Features</h4>
<ul>
<li>
<p>
The HiPE compiler's SPARC backend has been rewritten,
improving its correctness and long-term maintainability.</p>
<p>
Own Id: OTP-7133</p>
</li>
</ul>
<h3><a name="id2253932">1.12

<h4>Improvements and New Features</h4>
<ul>
<li>
<p>Minor Makefile changes.</p>
<p>Own Id: OTP-6689</p>

<h3><a name="id2253976">1.13
Hipe 3.6.2</a></h3>
<h4>Improvements and New Features</h4>

<h3><a name="id2254008">1.14
Hipe 3.6.1.1</a></h3>
<h4>Fixed Bugs and Malfunctions</h4>
<ul>
<li>
<p>Dialyzer could fail to analyze certain beam files that
used try/catch.</p>
<p>Own Id: OTP-6449 Aux Id: seq10563 </p>
</li>
</ul>
<h3><a name="id2254042">1.15
Hipe 3.6.1</a></h3>
<h4>Improvements and New Features</h4>
<ul>
<li>
<p>HiPE runtime system:</p>
<p>* added notes about supported systems to README</p>
<p>* support 32-bit x86 on FreeBSD</p>
<p>* autoenable HiPE on FreeBSD (32-bit x86) and Solaris
(64-bit x86)</p>
<p>* updated x86 runtime system to support glibc-2.5</p>
<p>* work around probable gcc-4.1.1 bug affecting the x86
runtime system</p>
<p>HiPE compiler:</p>
<p>* improved performance of integer multiplications on
all platforms</p>
<p>* corrected a code optimisation error in R11B-2 that
broke some bsl/bsr operations on all platforms</p>
<p>* corrected a type error in the ARM backend which
could cause the compiler to crash</p>
<p>* corrected an error in the SPARC backend's naive
register allocator which could throw the compiler into an
infinite loop</p>
<p>Own Id: OTP-6423</p>
</li>
</ul>
<h3><a name="id2254123">1.16
Hipe 3.6.0</a></h3>
<h4>Improvements and New Features</h4>
<ul>
<li>
<p>Support for native code on Solaris 10/AMD64.</p>
<p>Support for native code on FreeBSD/AMD64.</p>
<p>Native code now handles external funs (<span class="code">fun M:F/A</span>). Native code can now also apply so-called
tuple-funs (<span class="code">{M,F}</span>). (Tuple funs are NOT
recommended for new code; they are deprecated and will be
removed in some future release.)</p>
<p>Own Id: OTP-6305</p>
</li>
</ul>
<h3><a name="id2254283">1.17
Hipe 3.5.6</a></h3>
<h4>Improvements and New Features</h4>
<ul>
<li>
<p>Improved compilation of receives for the SMP runtime
system.</p>
<p>Improved code quality in HiPE compiler on ARM.</p>
<p>Fix bug in handling of re-raised exceptions in
try-catch.</p>
<p>(HiPE loader) When native code is incompatible with
the current runtime system, fall back to loading the BEAM
code.</p>
