+Subject: [PATCH] [llvm][PPC] Add missing case for 'I' asm memory operands
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+From https://llvm.org/docs/LangRef.html#asm-template-argument-modifiers:
+
+I: Print the letter ‘i’ if the operand is an integer constant,
+otherwise nothing. Used to print ‘addi’ vs ‘add’ instructions.
+
+Differential Revision: https://reviews.llvm.org/D103968
+
+(cherry picked from commit a9e4f91adf59bbc72541b96dd30245eaeeedf3ce)
