Hi Martin, The key is available on the keys.gnupg.net key server. I'm also attaching it to this email for convenience. Would posting it on the release page really help? The user would still need to trust the page to trust the key.

Hi, for programs linked with lld it's substantially slower to get callstacks in gdb, in comparison to gold-linked programs. Two measurements: lld gold 15 sec 3 sec 6 sec 2 sec This is a debug build, rather large binaries (lots of templates). I have seen even worse performance for debug+UBSan builds. I think code size (and therefore DWARF size) has an impact. Is there some information

Is the program being built by gcc or clang?

Hi, the attached example works with bfd-ld and with gold, but not with lld: $ cat rodatareloc.s ... .align 16 leaq .JTab(%rip), %r10 jmp *(%r10, %rdx, 8) ... .section .rodata .JTab: .quad .L00, .L01, .L02, .L03, .L04, .L05, .L06, .L07 .quad .L08, .L09, .L10, .L11, .L12, .L13, .L14, .L15, .L16 $ gcc -o rodatareloc.s.o -c rodatareloc.s $ lld -o rodatareloc.so -shared

...hard to tell what is wrong only with the information. If that is an open-source program, can you give me a link to that so that I can try? If that's a proprietary software you cannot share with me, you might want to produce small reproducible test case.

...a bug of LLD that it fails to fix the address for some reason. Can you dump that function with `objdump -d -r that-file.o`? With the -r option, objdump prints out relocation records. Relocation records are the information that linkers use to fix addresses.

...s not immediately an error, and LLD should pick one of them for each unique name, but this might not be workingw ell. - If you create a temporary object file using `ld.lld -r`, it should work. I don't know why, though. I'll continue investigating.

I have encountered very long compile times for three large source files containing generated/unrolled code at -O1. We are talking about 10+ hours here without completing, so it looks very much like an endless loop. The

Is there a file I can place in the netlogin directory (or anywhere else for that matter) that will represnet a logon script? I want to have my workstations auto-mount particular shares on the samba server, without the user having to make the mount. This way when I add new users, the shares are automatically present. If there is a script I can place somwehre, please tell me what it's name is

Hello, I could use a tip or two to get the following setup to work: I have a Win2k box with two network cards, the first connected to a private LAN (192.168.6.x) which has an uplink and a few other hosts connected, the second card is linked to a second private LAN with a backup box on it, which runs Debian sarge with Samba 3.0.14a-Debian. I want to backup from Win2k by mapping the shares to
