Extended Description

$ touch /tmp/test.c && ./bin/clang -mllvm -print-before=verify -c -emit-llvm /tmp/1.c

clang (LLVM option parsing): for the -print-before option: Cannot find option named 'verify'!

Looks like the passes were not registered by the time we parse the command line when invoked with clang. However, the option works perfectly fine with "llc". FYI, same is the case with "-mllvm print-after=<pass_name>

[nabeelomer]

This bug exists in Clang-10, Clang-11 and Clang master.

With recent clang (at commit 052a4b54a75364f13ea5001bba00691da4d8c239 , from March 21 2025) ,
running the command from the ticket description (with both -print-before & -print-after) no longer fails with the error.

Closing as Done, but please re-open if necessary.
