I'm trying to add echo " actual size of intp ${ac_cv_sizeof_int_p}" before follow line: ac_cv_sizeof_int_p=`cat conftestval` but quite wired, neither it print this line nor it print message "configure: failed program was:" , this is "if"! shouldn't it run into "yes" or "no"??

I'm set "-mfpu=neon -march=armv7-a -mtune=cortex-a9 -mfloat-abi=hard" in make.conf, but it changed to "-mfloat-abi=softfp", I think it have problem with -mfpu=neon. Is it possible to compile firefox with hardfloat abi?
Created attachment 279629 [details] patch for arm hardfloat toolchain firefox hard-coded with softfp, this patch will make it work with hardfloat toolchain
here is upstream bug about this, they do provide a patch to fix this problem. I've tried, it works fine.. Can you guys look into this? and apply those patches. following provided patches are my slightly modified version https://bugzilla.mozilla.org/show_bug.cgi?id=632915
Created attachment 279709 [details, diff] patch for ebuild this patch make it apply on condition (ARCH == arm && use hardfloat toolchain)
