I do not think we can use `update_llc_test_checks.py`. We should test `__patchable_function_entries` which can be scrubbed by `update_llc_test_checks.py`. The test is written in such a way with low maintenance: it will very unlikely change due to codegen differences. (The one `; CHECK-NEXT: addi sp, sp, -16` below is the only exception.) Testing more variants seems wasteful. ================ Comment at: llvm/test/CodeGen/RISCV/patchable-function-entry.ll:5-9 +;; RVC uses 2-byte nop. +; RUN: llc -filetype=obj -mtriple=riscv64 %s -o %t.o +; RUN: llvm-objdump -d %t.o | FileCheck %s --check-prefix=NORVC +; RUN: llc -filetype=obj -mtriple=riscv64 -mattr=+c %s -o %tc.o +; RUN: llvm-objdump -d %tc.o | FileCheck %s --check-prefix=RVC ---------------- jrtc27 wrote: > I don't think this is particularly useful if we've checked the assembly > output (and it stops us using update_llc_test_checks.py), we know nops get > emitted correctly, that's tested in various other places. objdump -d/llvm-objdump -d does not print c.nop => it is an important detail. Without it we cannot make sure the correct number of bytes is used.
