; RUN: llc < %s | FileCheck %s ; This test is reduced from https://github.com/llvm/llvm-project/issues/140491. ; It checks that when `@llvm.sincos.f32` is expanded to a call to ; `sincosf(float, float* out_sin, float* out_cos)` and the store of `%cos` to ; `%computed` is folded into the `sincosf` call. The use of `%cos`in the later ; `fneg %cos` -- which expands to a load of `%computed`, will perform the load ; before the `@llvm.lifetime.end.p0(%computed)` to ensure the correct value is ; taken for `%cos`. target triple = "x86_64-sie-ps5" declare void @use_ptr(ptr readonly) define i32 @sincos_stack_slot_with_lifetime(float %in) { ; CHECK-LABEL: sincos_stack_slot_with_lifetime: ; CHECK: # %bb.0: # %entry ; CHECK-NEXT: pushq %rbx ; CHECK-NEXT: .cfi_def_cfa_offset 16 ; CHECK-NEXT: subq $32, %rsp ; CHECK-NEXT: .cfi_def_cfa_offset 48 ; CHECK-NEXT: .cfi_offset %rbx, -16 ; CHECK-NEXT: leaq 12(%rsp), %rdi ; CHECK-NEXT: leaq 8(%rsp), %rbx ; CHECK-NEXT: movq %rbx, %rsi ; CHECK-NEXT: callq sincosf@PLT ; CHECK-NEXT: movss 8(%rsp), %xmm0 # xmm0 = mem[0],zero,zero,zero ; CHECK-NEXT: movaps %xmm0, 16(%rsp) # 16-byte Spill ; CHECK-NEXT: movq %rbx, %rdi ; CHECK-NEXT: callq use_ptr ; CHECK-NEXT: movss 12(%rsp), %xmm0 # xmm0 = mem[0],zero,zero,zero ; CHECK-NEXT: xorps {{\.?LCPI[0-9]+_[0-9]+}}(%rip), %xmm0 ; CHECK-NEXT: movss %xmm0, 8(%rsp) ; CHECK-NEXT: leaq 8(%rsp), %rdi ; CHECK-NEXT: callq use_ptr ; CHECK-NEXT: movaps 16(%rsp), %xmm0 # 16-byte Reload ; CHECK-NEXT: xorps {{\.?LCPI[0-9]+_[0-9]+}}(%rip), %xmm0 ; CHECK-NEXT: movss %xmm0, 8(%rsp) ; CHECK-NEXT: leaq 8(%rsp), %rdi ; CHECK-NEXT: callq use_ptr ; CHECK-NEXT: xorl %eax, %eax ; CHECK-NEXT: addq $32, %rsp ; CHECK-NEXT: .cfi_def_cfa_offset 16 ; CHECK-NEXT: popq %rbx ; CHECK-NEXT: .cfi_def_cfa_offset 8 ; CHECK-NEXT: retq entry: %computed = alloca float, align 4 %computed1 = alloca float, align 4 %computed3 = alloca float, align 4 %sincos = tail call { float, float } @llvm.sincos.f32(float %in) %sin = extractvalue { float, float } %sincos, 0 %cos = extractvalue { float, float } %sincos, 1 call void @llvm.lifetime.start.p0(i64 4, ptr nonnull %computed) store float %cos, ptr %computed, align 4 call void @use_ptr(ptr nonnull %computed) call void @llvm.lifetime.end.p0(i64 4, ptr nonnull %computed) call void @llvm.lifetime.start.p0(i64 4, ptr nonnull %computed1) %fneg_sin = fneg float %sin store float %fneg_sin, ptr %computed1, align 4 call void @use_ptr(ptr nonnull %computed1) call void @llvm.lifetime.end.p0(i64 4, ptr nonnull %computed1) call void @llvm.lifetime.start.p0(i64 4, ptr nonnull %computed3) %fneg_cos = fneg float %cos store float %fneg_cos, ptr %computed3, align 4 call void @use_ptr(ptr nonnull %computed3) call void @llvm.lifetime.end.p0(i64 4, ptr nonnull %computed3) ret i32 0 }
