[ID 20000905.004] IsUV vanished in 5.7.0
Message ID:
200009052032.XAA11664@kosh.hut.fi
This is a bug report for perl from jhi@kosh.hut.fi,
generated with the help of perlbug 1.32 running under perl v5.7.0.

In Digital UNIX the IsUV flag somehow vanished between 5.6.0 and 5.7.0.
$ LD_LIBRARY_PATH=$PWD ./perl -Ilib -MDevel::Peek -e '$a = 9223372036854775807;print Dump($a)'
SV = IV(0x140013cf8) at 0x140013870
REFCNT = 1
FLAGS = (IOK,pIOK)
IV = 9223372036854775807
$
No IsUV in FLAGS. Now watch the same with 5.6.0:
$ perl -MDevel::Peek -e '$a = 9223372036854775807;print Dump($a)'
SV = IV(0x140014100) at 0x140022900
REFCNT = 1
FLAGS = (IOK,pIOK,IsUV)
UV = 9223372036854775808
$
The IsUV knowledge is there, it works with constants:
$ LD_LIBRARY_PATH=$PWD ./perl -Ilib -MDevel::Peek -e 'print Dump(9223372036854775808)'
SV = IV(0x140013cf0) at 0x140001af0
REFCNT = 1
FLAGS = (IOK,READONLY,pIOK,IsUV)
UV = 9223372036854775808
The bug is OS-specific since in Solaris with 5.7.0:
$ perl -MDevel::Peek -e '$a=2147483648;print Dump($a)'
SV = IV(0xffc7c) at 0x100834
REFCNT = 1
FLAGS = (IOK,pIOK,IsUV)
UV = 2147483648
