Hi,

I'm new to SystemVerilog, and am trying to understand the
behavior of the 

   -sv_liblist "bootstrap file" 

as specified in the  SystemVerilog 3.1 LRM Annex F.

My reading of the specification says that a shared object 
specifed within a "bootstrap" file will override
a shared object specified using -sv_lib. 

Can you tell me why we need this behavior, and how and
when it is used?

Thanks for your help.

>From SystemVerilog LRM 3.1 Final:

At the top of page 340:

  Compiled object code can be specified by one of the following two methods:
  
  1) by an entry in a bootstrap file; see Annex F.2.1 for more details 
     on this file and its content. Its location shall be specified with one 
     instance of the switch -sv_liblist pathname. This switch can be used
     multiple times to define the usage of multiple bootstrap files.

  2) by specifying the file with one instance of the switch 
     -sv_lib pathname_without_extension (i.e., the filename shall be
specified without 
     the platform specific extension). The SystemVerilog application is
responsible
     for appending the appropriate extension for the actual platform. This
switch can
     be used multiple times to define multiple libraries holding object
code.

At the bottom of page 340:

  In case of multiple occurrences of the same file (files having the same 
  pathname or which can easily be identified as being identical; e.g., by 
  comparing the inodes of the files to detect cases where links are used to 
  refer the same file), the above order also identifies the precedence of
  loading; a file located by method 1) shall override
  files specified by method 2).
