From: Mike Frysinger Date: Sat, 21 Mar 2015 06:01:25 -0400 Subject: crypto: use bigint in x86-64 perl When building on x32 systems where the default type is 32bit, make sure we can transparently represent 64bit integers. Otherwise we end up with build errors like: /usr/bin/perl asm/ghash-x86_64.pl elf > ghash-x86_64.s Integer overflow in hexadecimal number at asm/../../perlasm/x86_64-xlate.pl line 201, <> line 890. ... ghash-x86_64.s: Assembler messages: ghash-x86_64.s:890: Error: junk '.15473355479995e+19' after expression We don't enable this globally as there are some cases where we'd get 32bit values interpreted as unsigned when we need them as signed.
