Summary: perl is compiled without 64bit int on i386 https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=168373 jvdias@xxxxxxxxxx changed: What |Removed |Added ---------------------------------------------------------------------------- Status|NEEDINFO |CLOSED Resolution| |WONTFIX ------- Additional Comments From jvdias@xxxxxxxxxx 2005-11-01 19:25 EST ------- When you are running perl on a 64-bit machine, and have installed the 64-bit architecture version, ie. on x86_64, perl-*.x86_64.rpm, not perl-*i386.rpm, then you do get 64-bit integers by default: e.g. on an x86_64, with perl*.x86_64 $ rpm -q perl --qf '%{ARCH}\n' x86_64 $ perl -e 'print ( 1 <<32, "\n" );' 4294967296 The 64bitint feature is meant to provide support for 64bit integers on 32 bit platforms, and has been associated with severe problems in the past. Using 64-bit integer emulation on 32-bit platforms would incur a heavy performance penalty for ALL applications, even those that make no use of 33+bit integers. It is also made redundant by use of the 'use bigint' pragma, which you can specify on the command line with -Mbigint, or in the environment of for your perl scripts on 32-bit platforms with the environment variable setting PERL5OPT=-Mbigint e.g, on an i386 machine: $ rpm -q perl --qf '%{ARCH}\n' i386 $ perl -e 'print ( 1<<32, "\n");' 1 $ PERL5OPT=-Mbigint perl -e 'print ( 1<<32, "\n");' 4294967296 Since there are many workarounds, and we don't want to incur a performance penalty for all perl scripts, and there have been problems with -D64bitint, I don't think we should enable this feature unless absolutely required - sorry. -- Configure bugmail: https://bugzilla.redhat.com/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.
