Bug ID: 66382
Summary: POWER8 Vector optimized implementation of __float128
(IEEE754 128-bit Binary Floating Point)
Product: gcc
Version: 6.0
Status: UNCONFIRMED
Severity: enhancement
Priority: P3
Component: libgcc
Assignee: unassigned at gcc dot gnu.org
Reporter: dje at gcc dot gnu.org
Target Milestone: ---
Using the enhanced Vector integer capabilities of the POWER8 ISA provide an all
vector implementation of Soft-float __float128. The current implementation
assumes that using 32- or 64-bit integer operations to implement __float128.
POWER8 should be able to provide all the required operations using only Vector
instruction. This should eliminate the any need to use GMP and additional local
memory the non-volatile Vector Registers should provide all the storage
capacity needed.
