Hi Rui, et al., I was experimenting yesterday with building lld on my POWER7 PPC64/Linux machine, and ran into an unfortunate problem.

Proposal for Mach-O support in llvm-objcopy: section renaming
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 ru...

LLD support for ld64 mach-o linker synthesised symbols
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 get...

[LLVMdev] n00b question: From module/bitcode to Mach-O dylib file directly?
...erence 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 against other BC-based and native files. These are clearly slightly different to native Mach-O obj files, and using a hex editor you can see the bit code enclosed within them - presumably they use the Mach-O envelope but store the BC code in a different section to where native code would be. Not sure if/where the exact form of the Mach-O file that carries bit code is documented. A...

Proposal for Mach-O support in llvm-objcopy: section renaming
...ith Seiya off the mailing list yesterday, and this was the suggestion we came up with, on the basis that GNU objcopy has support for the renaming for GDB support, but it might be confusing to people who are new to the system, so we provide a more expected output option. I'm not experienced with MachO at all, though, so we'd appreciate any feedback from any MachO users. Generally, Mach-O tools separate the segment name and the section name as different entries on the command line. The “<Segment Name>,<Section Name>” string is almost always an output format. Some examples includ...

Mach-O support in lld: what are the known issues?
...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 binary converter to convert the emitted ELF binary to a Mach-O binary, so that it can actually run on a platform that exists rather than the platform I'd prefer to exist. But that's probably just me being crazy, and I'm not going to work on it. :) On Tue, Jun 5, 2018 at 11:19 AM Andrew Kelley via llvm-dev < llvm-dev at lists.llvm.org> wr...

Mach-O support in lld: what are the known issues?
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...

Contributing LLD for Mach-O
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://rev...
