Hi Rui, et al., I was experimenting yesterday with building lld on my POWER7 PPC64/Linux machine, and ran into an unfortunate problem. When running the regressions tests under lit, almost all of the tests fail like this: terminate called after throwing an instance of 'std::system_error' what(): Resource temporarily unavailable ... 5 libc.so.6 0x00000080b7847238 abort +

Hi, I setup two sshd instance (using OpenSSH_3.5p1 bins on redhat7.2 kernel 2.4.20-19.7smp ) in order to achieve differnet sshd settings (e.g use different auth.method) on two different network interfaces (both on port 22). For example to setup Hostbased authetication on the 1st sshd and RSA pub. key auth. on the second: The 1st instance config file /etc/ssh/sshd_config looks like:

Hi, I''m glad to announce that I have mostly finished a port of GNU Mach to Xen, so that GNU/Hurd/Mach/Xen now works :) Samuel _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

Hi Rui, The motivation would be primarily that LLVM/Clang/LLD are community projects such that if I or someone in the community added support for e.g. symbol aliases, then it could be reviewed and potentially merged. ld64 on the other hand does not have a community process for patch submission and code review that I am aware of so its unlikely that if someone from the community came up with a

Hello When i try to make world (any) from xen-3.0.2 to xen-unstable-src I gat following error : gcc -O2 -fomit-frame-pointer -DNDEBUG -m64 -Wall -Wstrict-prototypes -Wdeclaration-after-statement -nostdinc -fno-builtin -fno-common -fno-strict-aliasing -iwithprefix include -Werror -Wno-pointer-arith -pipe -I/home/test1/xen-unstable/xen/include

Hi, I'm going to implement Mach-O support in llvm-objcopy. Before working on this, I'd like to hear your thoughts how llvm-objcopy should handle Mach-O section names. By convention, Mach-O section names are denoted by "<segment name>,<section name>". However, GNU objcopy renames them in the following rule [1]: - If the section name is well-known, rename it to an

Hi Folks, I have a question regarding LLD support for ld64 mach-o linker synthesised symbols. I did a quick search of the LLD source and I can not find support for them so before I start trying to use lld I thought I would ask. I have found a couple of cases where they are essential. i.e. where there is no other way to get the required information, such as getting the address of the mach-o

Actually, a related thing I've been curious about is the difference between the output of the llvm-gcc-4.2 front end on the Mac and a regular plain vanilla bit code file. The former file can be named a .o and the platform linker now knows how to do LTO while linking

Hey all, I was trying to install wine on OS X.4.11 using MacPorts - it had been running for about forty-five minutes - when my battery died. Nevermind the stupidity of not noticing the cord unplugged. Anyway, the install did not finish and now, when I try to "sudo port install wine" I get: Blahman:~ Blahman$ sudo port install wine ---> Building wine Error: Target

Given that the xenvm machine is based on vexpress but with an extremely limited selection of peripherals (the guest is supposed to use virtual devices instead), add "xen,xenvm" to the list of compatible machines in mach-vexpress. Changes in v2: - remove include skeleton; - use #address-cells = <2> and #size-cells = <2>; - remove the debug bootargs; - use memory@80000000

I'd be interested in the existence of a high-quality, open-source, portable linker for apple platforms, but not enough to help make that happen. If I _was_ gonna work on something related to that, I'd probably be inclined to instead add any required features to allow an ELF linker to target a notional darwin-elf target, and to have clang emit darwin-elf object files, and then write a

Hello all, I'm trying to better understand the state of Mach-O support in lld. The lld docs state that "the linker supports ELF (Unix), PE/COFF (Windows), Mach-O (macOS) and WebAssembly in descending order of completeness." [1] True to that statement, I found an email on this list from Jan 2018 stating that "MachO support in lld is not really ready for real world usage. It was

Hi all, We’re planning to contribute a new implementation of LLD for Mach-O, using the same design as the COFF and ELF ports. This design has proven to work very well for those ports, and we’re keen to explore it for Mach-O as well. Our work is based on an initial prototype created by Peter Collingbourne and Rui Ueyama. Our initial commit is up for review at https://reviews.llvm.org/D75382.
