-==================== Branch work162, patch #11 ====================
+==================== Branch work162, patch #24 ====================
+
+Add -mcpu=power11 tests.
+
+This patch adds some simple tests for -mcpu=power11 support.  In order to run
+these tests, you need an assembler that supports the -mpwr11 option.

+==================== Branch work162, patch #22 ====================
+
+Add -mcpu=power11 support part 2
+
+This patch allows GCC to be configured with the --with-cpu=power11 and
+--with-tune=power11 options.
+
+This patch passes -mpwr11 to the assembler if the user uses -mcpu=power11.
+
+This patch adds support for using "power11" in the __builtin_cpu_is built-in
+function.
 
-Add -mcpu=power11 support.
