Bug ID: 106564
Summary: PRU: Inefficient zero-extend from 32-bit to 64-bit
unsigned values
Product: gcc
Version: 13.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: dimitar at gcc dot gnu.org
Target Milestone: ---
Compiler uses 8-bit constant loads instead of 32-bit constant load to
zero-extend 32-bit unsigned values.
uint64_t test(uint32_t a)
{
return a;
}
test:
mov r0, r14
ldi r1.b0, (0) & 0xffff
ldi r1.b1, (0) & 0xffff
ldi r1.b2, (0) & 0xffff
ldi r1.b3, (0) & 0xffff
mov r14, r0
mov r15, r1
ret
