[Bug target/107533] New: Inefficient code sequence for fp16 testcase on aarch64
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=107533
Bug ID: 107533
Summary: Inefficient code sequence for fp16 testcase on aarch64
Product: gcc
Version: 13.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: ramana at gcc dot gnu.org
Target Milestone: ---
Derived from PR92999
struct phalf {
__fp16 first;
__fp16 second;
};
struct phalf phalf_copy(struct phalf* src) __attribute__((noinline));
struct phalf phalf_copy(struct phalf* src) {
return *src;
}
Compiling for AArch64 with a recent enough compiler produces.
phalf_copy:
ldr w0, [x0]
ubfxx1, x0, 0, 16
lsr w0, w0, 16
dup v0.4h, w1
dup v1.4h, w0
ret
Couldn't it just be ldr h0, [x0]
ldr h1, [x0, 2]
IIRC this is in base v8 rather than v8.2
regards
Ramana

That is of course a jolly good question :P Ramana
