Subject: [PATCH v2] ARM: Use different linker path for hardfloat ABI
Date: Sun, 22 Apr 2012 22:20:00 -0000 [thread overview]
Message-ID: <CANLjY-kZ6FakmtKkHjjC2YNgCBkydiNq8F81Fb7SgW0RE6iF5w@mail.gmail.com> (raw)
Change the dynamic linker path for ARM hard float executables.
Matches the path discussed and agreed on last week[1]. Carlos will
follow up with the matching patch to GLIBC[2]. I'm happy to if he's
busy.
OK for trunk?
