Uhm. So I guess that the toolchain I am using (arm-v7a-linux-gnueabihf from OSELAS.Toolchain-2013.12.2) shouldn't actually work. For some reason I haven't seen any problem yet. > > A newer version of these functions reached mainline in gcc-4.9. There are > optimized for cortex-a9.

However I just peeked at OSELAS.Toolchain-2014.12.1 and there is no trace of cortex-strings in arm-v7a-linux-gnueabihf_gcc-4.9.2_glibc-2.20_binutils-2.24_kernel-3.16-sanitized.ptxconfig (PTXCONF_GLIBC_EXTRA_ADDONS is empty). Am I looking in the wrong place ? Thanks, Guillermo -- ptxdist mailing list [email protected]
