Bug ID: 81959
Summary: PowerPC __float128 optimization fails with integer
PRE_INC addresses
Product: gcc

Status: UNCONFIRMED
Severity: normal
Priority: P3

Sample test
If you are doing 32-bit signed integer to IEEE 128-bit floating point on
power9, using an array where PRE_INC addresses are used, the compiler will fail
with an INSN not found error message.
