Bug ID: 31079
Summary: inconsistent opcode enums between AXV-512 and AVX/AVX2
Product: libraries
Version: trunk
Hardware: PC
OS: Windows NT
Status: NEW
Severity: normal
Priority: P
Component: Backend: X86
Assignee: [email protected]

Classification: Unclassified
I am creating this ticket in behalf of Gadi Haber who is waiting for his
Bugzilla account to be created.
There are cases of X86 AVX-512 opcode enums that are inconsistent with their
corresponding AVX opcode enums.
For example, the AVX-512 opcode: VBROADCASTSDZm (without an ‘r’ letter in its
suffix) has a corresponding AVX/AVX2 opcode VBROADCASTSDYrm which does include
the ‘r’ letter in its suffix.
For these cases it is recommended to rename the AVX-512 enums to be consistent
with the AVX counterpart.
See the table below of all such cases:
Current AVX-512 Proposed enum renaming
enum naming: for consistency with AVX/AVX2:
VBROADCASTSDZm VBROADCASTSDZrm
VBROADCASTSDZr VBROADCASTSDZrr
VBROADCASTSSZm VBROADCASTSSZrm
VBROADCASTSSZr VBROADCASTSSZrr
VPBROADCASTZr VPBROADCASTZrr
VPBROADCASTZm VPBROADCASTZrm
VPBROADCASTBrZr VPBROADCASTBZrr
VPBROADCASTZm VPBROADCASTZrm
VPBROADCASTZr VPBROADCASTZrr
VPEXTRWZrr VPEXTRWZri
VPINSRWZrr VPINSRWZrri
VPINSRWZrm VPINSRWZrmi
VPSLLDQZrr VPSLLDQZri
VPSRLDQZrr VPSRLDQZri
