Dunno :) I'm not a toolchain expert, so I'm happy to be overridden... but my _guess_ is: I think that in practice (at least on arm) cc -fPIC = cc -fPIE, and ld -pie just forces ld to generate PIC veneers (as for -shared). Beyond this, I think ld -shared / -pie / (nothing) probably just changes which linker script is used by default. U-Boot overrides the default with its own linker script anyway, so it may make no difference. ---Dave _______________________________________________ linaro-toolchain mailing list linaro-toolchain@lists.linaro.org http://lists.linaro.org/mailman/listinfo/linaro-toolchain
