New Revision: a2eb07aa55405f6e9bca0a0a31681053147e6540
URL: https://github.com/llvm/llvm-project/commit/a2eb07aa55405f6e9bca0a0a31681053147e6540
DIFF: https://github.com/llvm/llvm-project/commit/a2eb07aa55405f6e9bca0a0a31681053147e6540.diff
LOG: [VE] Support atomic exchange instructions
Support atomic exchange and atomic compare and exchange instructions.
Change CAS and TS1AM instructions for ISel patterns. Add selectADDRzi
pattern for them. Add TS1AM pseudo instruction also for better ISel.
Add shouldExpandAtomicRMWInIR() function to expand all atomicrmw
instructions except atomicrmw xchg. Add custom lower for i8/i16
atomicrmw xchg. Modify replaceFI to support CAS/TS1AM instructions
which use "reg+disp" operands instead of "reg+imm+disp" operands.
And, add several regression tests to check the correctness.

+;;; Test atomic compare and exchange weak for all types and all memory order
+;;;
+;;; Note:
+;;; - We test i1/i8/i16/i32/i64/i128/u8/u16/u32/u64/u128.
+;;; - We test relaxed, acquire, and seq_cst.
+;;; - We test only exchange with variables since VE doesn't have exchange
+;;; instructions with immediate values.
+;;; - We test against an object, a stack object, and a global variable.

+;;; Test atomic swap for all types and all memory order

+;;; Note:
+;;; - We test i1/i8/i16/i32/i64/i128/u8/u16/u32/u64/u128.
+;;; - We test relaxed, acquire, and seq_cst.
+;;; - We test only exchange with variables since VE doesn't have exchange
+;;; instructions with immediate values.
+;;; - We test against an object, a stack object, and a global variable.
