-==================== Branch work215, patch #1 ====================
+==================== Branch work215, patch #2 ====================
Add support for -mcpu=future
This patch adds the support that can be used in developing GCC support for
future PowerPC processors.
+This support is done by adding support for CPU ISA bits that are set directly
+via the -mcpu=<xxx> option, without having a -m<option> bit.
