Both are cross toolchains for Blackfin. The <code>bfin-elf</code> target toolchain uses <code>newlib</code> for <code>C</code> library and can be used to develop standalone applications. The <code>bfin-uclinux</code> target toolchain uses <code>uClibc</code> for <code>C</code> library and can be used to develop <code>uClinux</code> applications. </p><p>This release provides two <code>GCC</code> versions: 3.4.5 and <code>GCC</code> 4.1.0. This release starts to support a new ABI: Blackfin FDPIC ELF.</p><p>This release contains many bug fixes. It’s more stable and usable.</p></div><!-- SECTION [1-656] --><h3><a name="known_issues" id="known_issues">Known Issues</a></h3><div class="level3"><ol><li class="level1"><div class="li"> <code>elf2flt</code> passes <code>-r</code> option to <code>ld</code>. This option may make <code>C++</code> objects with <code>init_priority</code> attribute not initialized properly.</div></li><li class="level1"><div class="li"> Also because <code>elf2flt</code> passes <code>-r</code> option to <code>real.ld</code>. You cannot use <code>–gc-sections </code> for <code>ld</code> since it cannot be used together with <code>-r</code>.</div></li><li class="level1"><div class="li"> We do not support profiling using <code>gprof</code>. The latest <code>uClibc</code> no longer supports <code>gcc -fprofile-arcs -pg</code> style profiling. You may use other alternatives, like <code>OProfile</code>.</div></li><li class="level1"><div class="li"> Single stepping through hardware loop does not work when there are only one instruction in the loop. It will step over the whole loop instead.</div></li><li class="level1"><div class="li"> As expected, <code>-fstack-limit-symbol</code> cannot be used with multithreading applications.</div></li><li class="level1"><div class="li"> When running <code>bfin-elf-gdb</code>, interrupting the simulated program with <code>^C</code> does not work immediately. It will not take the effect until user press another key.</div></li><li class="level1"><div class="li"> <code>-fstack-limit-symbol</code> cannot be used with <code>-mfdpic</code>.</div></li><li class="level1"><div class="li"> <code>-fprofile-arcs</code> cannot be used with <code>-mfdpic</code>.</div></li></ol></div><!-- SECTION [657-1687] --><h3><a name="changes" id="changes">Changes</a></h3><div class="level3"><ol><li class="level1"><div class="li"> Starting from this release, <code>GCC</code> 4.1.0 is provided. <code>GCC</code> 3.4.x is included and recommended for maximum stability, but it will enter maintainence mode. Optimizations will only occur on <code>GCC</code> 4.1.x. Future <code>GCC</code> 3.4.x series will only contain bug fixes.</div></li><li class="level1"><div class="li"> The FLAT format for Blackfin has been changed to version 4, which is used by other architectures.</div></li></ol></div><!-- SECTION [1688-2072] --><h3><a name="improvement_since_last_release" id="improvement_since_last_release">Improvement since Last Release</a></h3><div class="level3"><ol><li class="level1"><div class="li"> This release of toolchain supports a new ABI: Blackfin FDPIC ELF ABI. An new option <code>-mfdpic</code> has been added for this ABI.</div></li><li class="level1"><div class="li"> <code>GCC</code> 4.1.0 now provides support Blackfin hardware loop.</div></li><li class="level1"><div class="li"> A new option <code>-mfast-fp</code> has been added to <code>GCC</code>. The application compiled with this option will call floating-point functions provided by a fast floating library <code>libbffastfp</code>, which is written in assembly and optimized for Blackfin, instead of the ones provided by <code>libgcc</code>. The floating-point functions in <code>libbffastfp</code> are several times faster than the ones in <code>libgcc</code>. <code>libbffastfp</code> relaxes some rules in IEEE floating-point standard of checking NaN for better performance.</div></li><li class="level1"><div class="li"> Blackfin <code>GAS</code> has been changed not to support assigning a value to a symbol with <code>SYM = EXPR</code>. This will allow <code>GAS</code> catch typos in register name. Use the .set directive instead.</div></li><li class="level1"><div class="li"> Now toolchain and kernel can be built on Mac <acronym title="Operating System">OS</acronym> X.</div></li><li class="level1"><div class="li"> Many builtin functions have been added for Blackfin in <code>GCC</code> to utilize the DSP instructions of Blackfin.</div></li></ol></div><!-- SECTION [2073-3159] --><h3><a name="bug_fixes" id="bug_fixes">Bug fixes</a></h3><div class="level3"><p>This section lists the bugs that are known to be fixed in this release.
