I'm finally getting around to bisecting binutils. I'm making some progress but I'm getting hung up on one thing. The build script keeps finding the "regular" linker at `/usr/bin/ld` instead of mine `/tmp/binutils/2.25/usr/local/bin/ld`. I tried to update the PATH environment variable such that mine is before `/usr/bin` but that doesn't seem to work. Is there an argument to send that can force mine? > > Meador Inge has also mentioned this bug: > https://llvm.org/bugs/show_bug.cgi?id=26580 > > Right now, it does not seem clear to me that we have an understanding > what the issue is, which component is broken (LLVM, Swift's IRGen, or > binutils), and if the breakage was accidental or intentional (e.g., to > fix something else). > > Previous thread on this topic: > > https://lists.swift.org/pipermail/swift-dev/Week-of-Mon-20160215/001176.html > https://lists.swift.org/pipermail/swift-dev/Week-of-Mon-20160222/001190.html > > Dmitri > > On Mon, Feb 29, 2016 at 8:04 PM, Ryan Lovelett > <swift-...@ryan.lovelett.me> wrote: > > Perfect. > > > > That corresponds with what I am seeing.
