have 3 entrypoints in trinity list on CentOS 6

Hi All:

I'm beginner for Trinity tool, it's very good. Thanks a lot.

When try command ./trinity -L , got some syscalls have 3 entrypoint , e.g:
32-bit entrypoint 28 fstatfs : Enabled
32-bit entrypoint 100 fstatfs : Enabled
64-bit entrypoint 138 fstatfs : Enabled
...
32-bit entrypoint 109 uname : Enabled
32-bit entrypoint 122 uname : Enabled
64-bit entrypoint 63 uname : Enabled
...
32-bit entrypoint 187 sendfile : Enabled
32-bit entrypoint 239 sendfile : Enabled
64-bit entrypoint 40 sendfile : Enabled
...
32-bit entrypoint 82 select : Enabled AVOID
32-bit entrypoint 142 select : Enabled AVOID
64-bit entrypoint 23 select : Enabled AVOID
...
32-bit entrypoint 76 getrlimit : Enabled
32-bit entrypoint 191 getrlimit : Enabled
64-bit entrypoint 97 getrlimit : Enabled
...

And seems only two of them syscalls are using in testing; I'm using "Latest
release is v1.2, released on Jul 22nd 2013" on CentOS6.4, not sure it's my
test bed issue, please help to check.

Thanks.
Frank

This is just a cosmetic thing.  Ignoring the 64bit variants:

This is actually fstatfs & fstatfs64

'olduname' & 'uname'
 
 > 32-bit entrypoint 187 sendfile : Enabled
 > 32-bit entrypoint 239 sendfile : Enabled

'sendfile' & 'sendfile64'

 > 32-bit entrypoint 82 select : Enabled AVOID
 > 32-bit entrypoint 142 select : Enabled AVOID
 
'select' & 'newselect'
 
Because trinity treats all these functions the same, rather than duplicate
everything twice, we re-use the same syscall structure for both entries.
