Subject: Setting ARM dynamic linker name from commandline
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=90cbf30ef14fd31233a5f6543c28f3d39fb1d6df;p=clang

Setting ARM dynamic linker name from commandline

Currently trigger to select hard-float linker is only based of -gnueabihf
appearing in target triplet, but we should also select it when hardfloat
is requested via cmdline.

Patch by Khem Raj.
