Peter suggested raising your problem on the llvm-dev mailing list. Have you done that? Personally I am opposed to this change. The compiler driver (gcc,clang) has a set of arch/OS dependent defaults. It seems weird/redundant to add another sets of defaults on the linker side. A few replies to some bullet points you raised in a previous comment. > GCC to pass lld flags Compiler drivers have more information (OS version, toolchain path, linker name, etc) to decide if some linker flags are needed. Some `-f` options can generate linker options as well. > rpath behavior From my reading of https://blog.netbsd.org/tnf/entry/the_first_report_on_lld , I don't see why NetBSD must maintain the --disable-new-dtags local patch. > GNU stack generation `-z nognustack` makes sense to me. I commented on D56554 <https://reviews.llvm.org/D56554>. > specify default target/emulation search paths This job should be done in the compiler drivers. > disable 3 segments Personally I don't think it is really necessary to change the default.. But you can add --no-rosegment if you are really bothered by the layout. I think your requirement can be simply accomplished with a shell script wrapper called `ld`: #!/bin/sh # customization exec ld.lld <options> CHANGES SINCE LAST ACTION https://reviews.llvm.org/D56650/new/ https://reviews.llvm.org/D56650 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
