     1 Original patch from: ../crosstool-NG/ct-ng.trunk/patches/binutils/2.19/150-warn-textrel.patch

     4 Original patch from Gentoo:

     5 gentoo/src/patchsets/binutils/2.19/66_all_binutils-2.18.50.0.2-warn-textrel.patch

     7 textrels are bad for forcing copy-on-write (this affects everyone),

     8 and for security/runtime code generation, this affects security ppl.

     9 But in either case, it doesn't matter who needs textrels, it's

    10 the very fact that they're needed at all.
