teapotd opened PR #1510 from abi-i128-fix to master:

Current implementation of legalize_signature for x86 ABI assumes struct-return parameters can be generated only for multi-return functions. This is incorrect: functions can become multi-return after splitting return values in legalize_args - for example functions that return i128. This PR removes this assumption. Fixes #1162.

[x] This has been discussed in issue #1162

[x] This PR contains test cases, if meaningful.

[ ] I'm new to the project, I don't know who could review this.
