Hi,
I ran into PR60947, in which GCC understands the return value of
memset is the first argument passed in, according to standard, then

Thanks for elaborating.

Hi,
I ran into PR60947, in which GCC understands the return value of
memset is the first argument passed in, according to standard, then
does optimization like below:
movip, sp
stmfdsp!, {r4, r5, r6, r7, r8, r9, r10, fp, ip, lr, pc}
subfp, ip, #4
subsp, sp, #20
