From: Nick Clifton Date: Fri, 25 Apr 2014 16:00:20 +0000 (+0100) Subject: This fixes a compile time warning which is being treated as an error. Older X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=88667baf24e71481f0002c0452b94a1d53116725;p=binutils-gdb.git This fixes a compile time warning which is being treated as an error. Older versions of gcc complain about part of a conditional expression always evaluating to false because of the size of the operands involved, even when the entire expression is already known to be false. * peXXigen.c (_bfd_XXi_swap_sym_out): Another fix for building on a 342-bit host.
