+==================== Branch work211-cmodel, patch #300 ====================
+
+PR target/120681 - allow -mcmodel=large with prefixed addressing
+
+When I implemented the pc-relative support for power10 in GCC, I disabled using
+pc-relative support for -mcmodel=large. At the time, I didn't want to
dig into
+the issues. It is now time to allow -mcmodel=large to generate pc-relative
+code.
+
+This patch allows -mcmodel=large to use prefixed addressing on power10,
power11,
+and possibly other future PowerPC processors.
+
+This patch deletes the code that disallows -mprefixed and -mcmodel=large. By
+deleting the code, it allows the normal pc-relative addressing to be used. For
+static variables, pc-relative addressing will be used. For external variables,
+we will generate the normal code that uses '@got@pcrel' addressing to load up
+the external address and use this address as a pointer to do the load or store.
