The dynamic linker for GHCi.
This module deals with the top-level issues of dynamic linking,
calling the object-code linker and the byte-code linker where
Get the HValue associated with the given name.
May cause loading the module that contains the name.
Throws a ProgramError if loading fails or the name cannot be found.
|Display the persistent linker state.
Link a single expression, including first linking packages and
modules that this expression depends on.
Raises an IO exception (ProgramError) if it can't find a compiled
version of the dependents to link.
|-> [Linkable]||The linkables to *keep*.
|-> IO ()|
Unloading old objects ready for a new compilation sweep.
The compilation manager provides us with a list of linkables that it
considers "stable", i.e. won't be recompiled this time around. For
each of the modules current linked in memory,
- if the linkable is stable (and it's the same one -- the user may have
recompiled the module on the side), we keep it,
- otherwise, we unload it.
- we also implicitly unload all temporary bindings at this point.
|Temporarily extend the linker state.
|Link exactly the specified packages, and their dependents (unless of
course they are already linked). The dependents are linked
automatically, and it doesn't matter what order you specify the input
Initialise the dynamic linker. This entails
a) Calling the C initialisation procedure,
b) Loading any packages specified on the command line,
c) Loading any packages specified on the command line, now held in the
-l options in v_Opt_l,
d) Loading any .o/.dll files specified on the command line, now held
e) Loading any MacOS frameworks.
NOTE: This function is idempotent; if called more than once, it does
nothing. This is useful in Template Haskell, where we call it before
trying to link.
Given a data constructor in the heap, find its Name.
The info tables for data constructors have a field which records
the source name of the constructor as a Ptr Word8 (UTF-8 encoded
string). The format is:
We use this string to lookup the interpreter's internal representation of the name
using the lookupOrig.
