Bug ID: 42744
Summary: [AMDGPU][MC][GFX10] 64-bit shift instructions should
only allow 1 scalar value
Product: libraries
Version: trunk
Hardware: PC
OS: All
Status: NEW
Severity: enhancement
Priority: P
Component: Backend: AMDGPU
Assignee: unassignedb...@nondot.org
Reporter: dpreobrazhen...@luxoft.com
CC: llvm-bugs@lists.llvm.org
GFX10 enables 2 scalar values for VOP except for 64-bit shift instructions
which may use only one. Instructions like this:
v_ashrrev_i64 v[0:1], 0xaf123456, s[0:1]
should trigger an error.
