 ====== Deploy PIC32MX gcc toolchain on Solaris ======
-The toolchain no longer works on s11u4sru37 due to missing /usr/lib/libmpc.so.2 and /usr/lib/libmpfr.so.1 libraries - /opt/mipsel/libexec/gcc/mipsel/4.5.2/cc1 depends on them.
+  * The toolchain **binutils-2.36**, **gcc-10.3.0**, **newlib-1.4** no longer works after upgrade from **SRU62** to **SRU63**, since **libisl** was upgraded from version **15** to version **23**. Re-compilation with libisl 23 fixed the problem.
-Reason being the libraries were upgraded to /usr/lib/limpc.so.3 and /usr/lib/libmpfr.so.4 respectively.

 To workaround the issue, missing libraries were copied from s11u4sru30 where both old as well as new versions of those libraries are available.
-Also, new tool chain has been built based on binutils 2.37, gcc 9.4.0, newlib 4.1.0
+Also, new tool chain has been built based on binutils 2.36, gcc 10.3.0, newlib 4.1.0.

+$ sudo make install
+</code>
 ===== binutils 2.37 =====
+  * man pages were not built - instead use binutils 2.36
   * save existing toolchain and prepare for building new one

+===== gcc 10.3.0 with newlib 4.1.0 =====
+  * prepare working area
+<code>

+  * build and install (tools will be installed into /opt/mipsel/ directory). Building gcc with newlib is done in three steps.

+$ make
+$ sudo make install
+</code>
+  * **--enable-multilib** - builds several variants of libraries (big-endian, little-endian hard-float and soft-float). Default is little-endian hard-float.
+<code>
