The IRParser offers a higher level API, that allows us to also read bitcode assembly, and not only compiled bitcode. This allows us to skip the `llvm-as %s -o %t.bc` step in several tests. I only updated 3 tests to show the difference; but we have more than 500 occurences of `llvm-as %s -o` in the tests: > $/repo/test$ grep -r "llvm-as %s -o" | cut -d':' -f1 | sort -u | wc -l > 506

I'm clueless since it seems to work on my system (with debug and asan enabled). I'll try to rerun the CI jobs re-check. |

@jmmartinez I believe it's unrelated with your PR as I also see the same failure in #3398 . Taking a look |

This is a follow-up of #3399 . After #3399, we do not need to run `llvm-as`, we can directly consume the textual llvm-ir representation. This patch profits from this to clean this pattern in the test: ```bash RUN: llvm-as %s -o %t.bc RUN: llvm-spirv %t.bc ... ``` And replaces it by ```bash RUN: llvm-spirv %s ... ```
