[PATCH] D73290: [PowerPC] Add clang -msvr4-struct-return for 32-bit ELF

[Mark Millard via Phabricator via cfe-commits]

markmi added a comment.

I built and installed ports, what built vs. did-not was the same as before applying the update, with the same failure details having nothing to do with this change. I then ran the FreeBSD kyua tests and the result match what I got prior to the update.

These tests are not about gcc/g++ ABI compatibility, but FreeBSD seems to work fine when built based on the change.

(FYI, given the ABI incompatibility, I did not try to self-host getting from one ABI to the other. I instead installed the updated FreeBSD as a separate drive on another system and then put that drive back in its normal system and booted from it.)

I'm not aware of anything around that makes for a good, fairly-general gcc/g++ ABI compatibility test.
