[PATCH v2] ARM: Use different linker path for hardfloat ABI

by Michael Hope

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? -- Michael [1] http://sourceware.org/ml/libc-ports/2012-04/msg00060.html [2] http://sourceware.org/ml/libc-ports/2012-04/msg00064.html 2012-04-23 Michael Hope <michael.hope(a)linaro.org> * config/arm/linux-eabi.h (GLIBC_DYNAMIC_LINKER_HARD_FLOAT): Define.

Armhf dynamic linker path

by Steve McIntyre

Hi folks, We really need to push on with getting the loader path for armhf standardised. The path that was agreed months ago is /lib/arm-linux-gnueabihf/ld-linux.so.3 but clearly not everybody is using that yet. Dann has just posted an updated patch for gcc, and we want to get this reviewed / fixed up / accepted ASAP. Then we may need to backport it to older gcc releases. This is *important* so that we can help vendors release binaries that work on any hard-float distribution. For people who have made binaries that still use the old, broken location /lib/ld-linux.so.3, we can put symlinks in place *for now* but in the longer term as many distros switch to multi-arch the symlink is not an acceptable solution. I'm working on a more complete spec document for armhf to help us with this kind of thing, but it's not going as smoothly as I'd hoped and I don't want to wait for that as a blocker on the linker path. Cheers, -- Steve McIntyre steve.mcintyre(a)linaro.org <http://www.linaro.org/> Linaro.org | Open source software for ARM SoCs
