Bug ID: 37565
Summary: [llvm-exegesis] Wrong serial chain generated.
Product: new-bugs
Version: unspecified
Hardware: PC
OS: Linux
Status: NEW
Severity: enhancement
Priority: P
Component: new bugs

CVTSS2SDrr_Int only reads from one operand and only writes to the other
operand. A serial chain requires the two operands to be the same.
I guess the instruction incorrectly specifies a read from the operand it writes
to.
