+==================== Branch work164-bugs, patch #201 ====================
+
+Add power10 ori/oris and xori/xoris fusion support.
+
+2024-04-09  Michael Meissner  <meissner@linux.ibm.com>
+
+gcc/
+
+	* config/rs6000/fusion.md: Regenerate.
+	* config/rs6000/genfusion.md (gen_wide_immediate): Add wide immediate
+	fusion patterns.
+	* config/rs6000/rs6000.md (IORXOR_OP): New code attribute.
+	(ior, xor splitter): Do not split ior/xor patterns that could be fused
+	on power10.
+
+==================== Branch work164-bugs, patch #200 ====================
+
+Add power10 wide immediate fusion
+

+
+	PR target/108018
+	* config/rs6000/rs6000.md (tocref<mode>_p10_fusion): New insn.
+	(tocref<mode>): Don't allow tocrev<mode> if tocref<mode>_p10_fusion
+	would be used.
+
+==================== Branch work164-bugs, patch #10 from work164 ====================
+
+Add -mcpu=future support.
+
+This patch adds the future option to the -mcpu= and -mtune= switches.
+
+This patch treats the future like a power11 in terms of costs and reassociation
+width.
+
+This patch issues a ".machine future" to the assembly file if you use
+-mcpu=power11.
+
+This patch defines _ARCH_PWR_FUTURE if the user uses -mcpu=future.
+
+This patch allows GCC to be configured with the --with-cpu=future and
+--with-tune=future options.
+
+This patch passes -mfuture to the assembler if the user uses -mcpu=future.
+

+
+==================== Branch work164-bugs, patch #3 from work164 ====================
+
+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 appropriate option for
+supporting the Power11 processor (-mpower11 under Linux or -mpwr11 under AIX).

+	effective target.
+
+==================== Branch work164-bugs, patch #2 from work164 ====================
+
+Add -mcpu=power11 tuning support.
+
+This patch makes -mtune=power11 use the same tuning decisions as -mtune=power10.
+
