+ <p>
+ Possible to run HiPE without floating point exceptions
+ (FPE). Useful on platforms that lack reliable FPE. Slower
+ float operations compared to HiPE with FPE.</p>
+ <p>
+ Own Id: OTP-9724</p>
+ </item>
+ <item>
+ <p>
+ HiPE compiler: The possibility to compile and load
+ selected functions from a module has been removed.</p>
+ <p>
+ *** POTENTIAL INCOMPATIBILITY ***</p>
+ <p>
+ Own Id: OTP-9751</p>
+ </item>
+ <item>
+ <p>
+ <c>filename:find_src/1,2</c> will now work on stripped
+ BEAM files (reported by Per Hedeland). The HiPE compiler
+ will also work on stripped BEAM files. The BEAM compiler
+ will no longer include compilation options given in the
+ source code itself in <c>M:module_info(compile)</c>
+ (because those options will be applied anyway if the
+ module is re-compiled).</p>
