[PATCH] D153129: [AArch64][RCPC3] Instruction selection for LDAP1/STL1 instructions

Mon Jun 19 08:01:42 PDT 2023

LukeGeeson added a comment.

>From my understanding of LDAP1 and STL1 these instructions (in particular LDAP) have the same ordering semantics as LDAPR [1] and hence I expect the correctness argument will be similar to the LDAPR testing [2].

I expect this patch is ok (as long as LDAP1 is not used for SC accesses) - but I'll need to implement some testing to be certain.
