I assume that we need to reimplement this in the context of lld:
NetBSD::NetBSD(const Driver &D, const llvm::Triple &Triple, const ArgList
&Args)
: Generic_ELF(D, Triple, Args) {
if (!Args.hasArg(options::OPT_nostdlib)) {
// When targeting a 32-bit platform, try the special directory used on
// 64-bit hosts, and only fall back to the main library directory if that
// doesn't work.
// FIXME: It'd be nicer to test if this directory exists, but I'm not sure
// what all logic is needed to emulate the '=' prefix here.
switch (Triple.getArch()) {
case llvm::Triple::x86:
getFilePaths().push_back("=/usr/lib/i386");
break;
case llvm::Triple::arm:
case llvm::Triple::armeb:
case llvm::Triple::thumb:
case llvm::Triple::thumbeb:
switch (Triple.getEnvironment()) {
case llvm::Triple::EABI:
case llvm::Triple::GNUEABI:
getFilePaths().push_back("=/usr/lib/eabi");
break;
case llvm::Triple::EABIHF:
case llvm::Triple::GNUEABIHF:
getFilePaths().push_back("=/usr/lib/eabihf");
break;
default:
getFilePaths().push_back("=/usr/lib/oabi");
break;
}
break;
case llvm::Triple::mips64:
case llvm::Triple::mips64el:
if (tools::mips::hasMipsAbiArg(Args, "o32"))
getFilePaths().push_back("=/usr/lib/o32");
else if (tools::mips::hasMipsAbiArg(Args, "64"))
getFilePaths().push_back("=/usr/lib/64");
break;
case llvm::Triple::ppc:
getFilePaths().push_back("=/usr/lib/powerpc");
break;
case llvm::Triple::sparc:
getFilePaths().push_back("=/usr/lib/sparc");
break;
default:
break;
}
getFilePaths().push_back("=/usr/lib");
}
}
