How to set passes for clspv-opt?

[robquill]

Hi,

When I try to run:

./clspv-opt --replace-physical-pointer-bitcasts broken.ll

I get this error message:

No passes specified to run!

./clspv-opt --help-list-hidden shows that --replace-physical-pointer-bitcasts is an option

Also running ./clspv-opt on it's own also gives the "No passes specified to run!" error message.

I used commit 3374c5a

Does anyone know how to debug which passes are available?

here is how to run a specific pass with clspv-opt:

clspv-opt <source> -o <destination> --passes=<comma_separated_list_of_passes>

Here is an example:

clspv/test/PointerCasts/srcGTdst/store_cast_float2_to_int.ll

Line 1 in 3374c5a

; RUN: clspv-opt %s -o %t --passes=simplify-pointer-bitcast,replace-pointer-bitcast

For clspv specific passes, one can find the list here:

--replace-physical-pointer-bitcasts is an option, not a pass.
It is enabled by default: https://github.com/google/clspv/blob/3374c5a5abff3aa655934767c5d4fbc0008bd52e/lib/ReplacePointerBitcastPass.cpp#L44C1L47C1

OK, got it. Thanks. So what I should have done is: ./clspv-opt --passes=replace-pointer-bitcasts broken.ll which works (or rather, reproduces the assert I wanted to debug).

Thanks for the quick reply. I will close this issue.
