Surely it's 04c9cf5c786b94fbe3f6f21f06cae73a7575ff7a ('Implement new RTL optimizations pass: fold-mem-offsets') if that list is to be believed...

-fno-fold-mem-offsets doesn't seem to help...

Huh.

04c9cf5c786b94fbe3f6f21f06cae73a7575ff7a is the first bad commit
commit 04c9cf5c786b94fbe3f6f21f06cae73a7575ff7a

    Implement new RTL optimizations pass: fold-mem-offsets

    This is a new RTL pass that tries to optimize memory offset calculations
    by moving them from add immediate instructions to the memory loads/stores.
    For example it can transform this:

Comment 8 Sam James archtester

2023-11-06 11:57:19 UTC

and indeed Python built at gcc 964fd402c9b48eb4da91fb3e4e45d4560d6c676c ('d: Merge upstream dmd, druntime 4c18eed967, phobos d945686a4.') is fine.

Comment 9 Sam James archtester

2023-11-06 17:12:33 UTC

OK, -fno-fold-mem-offsets *does* suppress it on trunk so I must have made a mistake before.

Comment 10 Sam James archtester

This is workedaroundededed upstream.
