It works after apply together with another patch "http://gcc.gnu.org/ml/gcc-patches/2013-10/msg01445.html", which seems to be provided by you. Good work. My target is 32bits i686. I use ct-ng to build gcc and set CT_ARCH_32=y, CT_ARCH_BITNESS=32. ^ permalink raw reply [flat|nested] 4+ messages in thread
