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)
