| 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. |
