||||
Subject: [PATCH] cmd/compile: fix regression in PPC64.rules move zero
|
||||
|
||||
When a MOVDstorezero (8 bytes) is used the offset field
|
||||
in the instruction must be a multiple of 4. This situation
|
||||
had been corrected in the rules for other types of stores
|
||||
but not for the zero case.
|
||||
|
||||
This also removes some of the special MOVDstorezero cases since
|
||||
they can be handled by the general LowerZero case.
|
||||
|
||||
Updates made to the ssa test for lowering zero moves to
|
||||
include cases where the target is not aligned to at least 4.
|
||||
|
||||
Fixes #21947
