Bug ID: 79252
Summary: Improve code generation of vec_insert on PowerPC ISA
2.07 (i.e. power8)
Product: gcc
Version: 7.0
Status: UNCONFIRMED
Severity: enhancement
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: meissner at gcc dot gnu.org
Target Milestone: ---
On PowerPC compiles with -mcpu=power8, if you do a vec_insert on vector types
that have 8, 16, or 32-bit element sizes (i.e. char, short, int, float) with a
constant element number, we generate a vector store, element store, and vector
load instead of using a series of instructions instead of generating a
store-hit-load event.
