86effd0d - ARC: dw2 unwind: enable cfi pseudo ops in string lib

ARC: dw2 unwind: enable cfi pseudo ops in string libThis uses a new set of annoations viz. ENTRY_CFI/END_CFI to enabel cfiops generation.Note that we didn't change the normal ENTRY/EXIT as we don't actuallywant unwind info in the trap/exception/interrutp handlers which usethese, as unwinder then gets confused (it keeps recursing vs. stopping).Semantically these are leaf routines and unwinding should stop when ithits those routines.Before------ 28.52% 1.19% 9929 hackbench libuClibc-1.0.17.so [.] __write_nocancel | ---__write_nocancel |--8.95%--EV_Trap | --8.25%--sys_write | |--3.93%--sock_write_iter ... |--2.62%--memset <==== [LEAF entry as no unwind info] ^^^^^^After----- 29.46% 1.24% 13622 hackbench libuClibc-1.0.17.so [.] __write_nocancel | ---__write_nocancel |--9.31%--EV_Trap | --8.62%--sys_write | |--4.17%--sock_write_iter ... |--6.19%--sys_write | --6.19%--sock_write_iter | unix_stream_sendmsg | |--1.62%--sock_alloc_send_pskb | |--0.89%--sock_def_readable | |--0.88%--_raw_spin_unlock_irqrestore | |--0.69%--memset | | ^^^^^^ <==== [now in proper callframe] | | | --0.52%--skb_copy_datagram_from_iterSigned-off-by: Vineet Gupta List of files: /linux-6.15/arch/arc/lib/memset.S

ec7ac6af - ARC: switch to generic ENTRY/END assembler annotations

Fri, 07 Feb 2014 08:17:43 +0000

ARC: switch to generic ENTRY/END assembler annotationsWith commit 9df62f054406 "arch: use ASM_NL instead of ';'" the genericmacros can handle the arch specific newline quirk. Hence we can get ridof ARC asm macros and use the "C" style macros.Signed-off-by: Vineet Gupta List of files: /linux-6.15/arch/arc/lib/memset.S
