This should hopefully makes changes to the O0 pipeline obvious; it's easy to require expensive passes, and this helps make informed decisions. Case in point: in the few weeks separating the time when I initially wrote this patch to the time when I committed, the test regressed as r302103 added another use of DT! llvm-svn: 302608 --- llvm/test/CodeGen/X86/O0-pipeline.ll | 71 ++++++++++++++++++++++++++++++++++++ 1 file changed, 71 insertions(+) create mode 100644 llvm/test/CodeGen/X86/O0-pipeline.ll diff --git a/llvm/test/CodeGen/X86/O0-pipeline.ll b/llvm/test/CodeGen/X86/O0-pipeline.ll new file mode 100644 index 0000000..ba95eba --- /dev/null +++ b/llvm/test/CodeGen/X86/O0-pipeline.ll @@ -0,0 +1,71 @@ +; RUN: llc -mtriple=x86_64-- -O0 -debug-pass=Structure < %s -o /dev/null 2>&1 | FileCheck %s + +; REQUIRES: asserts + +; CHECK-LABEL: Pass Arguments: +; CHECK-NEXT: Target Library Information +; CHECK-NEXT: Target Transform Information +; CHECK-NEXT: Target Pass Configuration +; CHECK-NEXT: Type-Based Alias Analysis +; CHECK-NEXT: Scoped NoAlias Alias Analysis +; CHECK-NEXT: Assumption Cache Tracker +; CHECK-NEXT: Create Garbage Collector Module Metadata +; CHECK-NEXT: Machine Module Information +; CHECK-NEXT: Machine Branch Probability Analysis +; CHECK-NEXT: ModulePass Manager +; CHECK-NEXT: Pre-ISel Intrinsic Lowering +; CHECK-NEXT: FunctionPass Manager +; CHECK-NEXT: Expand Atomic instructions +; CHECK-NEXT: Dominator Tree Construction +; CHECK-NEXT: Basic Alias Analysis (stateless AA impl) +; CHECK-NEXT: Module Verifier +; CHECK-NEXT: Lower Garbage Collection Instructions +; CHECK-NEXT: Shadow Stack GC Lowering +; CHECK-NEXT: Remove unreachable blocks from the CFG +; CHECK-NEXT: Inserts calls to mcount-like functions +; CHECK-NEXT: Rewrite Symbols +; CHECK-NEXT: FunctionPass Manager +; CHECK-NEXT: Dominator Tree Construction +; CHECK-NEXT: Exception handling preparation +; CHECK-NEXT: Dominator Tree Construction +; CHECK-NEXT: Natural Loop Information +; CHECK-NEXT: Scalar Evolution Analysis +; CHECK-NEXT: Safe Stack instrumentation pass +; CHECK-NEXT: Insert stack protectors +; CHECK-NEXT: Module Verifier +; CHECK-NEXT: Dominator Tree Construction +; CHECK-NEXT: Basic Alias Analysis (stateless AA impl) +; CHECK-NEXT: Function Alias Analysis Results +; CHECK-NEXT: X86 DAG->DAG Instruction Selection +; CHECK-NEXT: X86 PIC Global Base Reg Initialization +; CHECK-NEXT: Expand ISel Pseudo-instructions +; CHECK-NEXT: Local Stack Slot Allocation +; CHECK-NEXT: X86 WinAlloca Expander +; CHECK-NEXT: Eliminate PHI nodes for register allocation +; CHECK-NEXT: Two-Address instruction pass +; CHECK-NEXT: Fast Register Allocator +; CHECK-NEXT: Bundle Machine CFG Edges +; CHECK-NEXT: X86 FP Stackifier +; CHECK-NEXT: Prologue/Epilogue Insertion & Frame Finalization +; CHECK-NEXT: Post-RA pseudo instruction expansion pass +; CHECK-NEXT: X86 pseudo instruction expansion pass +; CHECK-NEXT: Analyze Machine Code For Garbage Collection +; CHECK-NEXT: X86 vzeroupper inserter +; CHECK-NEXT: Contiguously Lay Out Funclets +; CHECK-NEXT: StackMap Liveness Analysis +; CHECK-NEXT: Live DEBUG_VALUE analysis +; CHECK-NEXT: Insert fentry calls +; CHECK-NEXT: MachineDominator Tree Construction +; CHECK-NEXT: Machine Natural Loop Construction +; CHECK-NEXT: Insert XRay ops +; CHECK-NEXT: Implement the 'patchable-function' attribute +; CHECK-NEXT: Lazy Machine Block Frequency Analysis +; CHECK-NEXT: Machine Optimization Remark Emitter +; CHECK-NEXT: MachineDominator Tree Construction +; CHECK-NEXT: Machine Natural Loop Construction +; CHECK-NEXT: X86 Assembly Printer +; CHECK-NEXT: Free MachineFunction + +define void @f() { + ret void +} -- 2.7.4
