12 years agoMake the GHCi linker handle partially stripped object files (#5004)
Duncan Coutts [Thu, 12 May 2011 15:25:41 +0000 (16:25 +0100)]
Make the GHCi linker handle partially stripped object files (#5004)

When you use 'strip --strip-unneeded' on a ELF format .o or .a file, if
the object file has no global/exported symbols then 'strip' ends up
removing the symbol table entirely. Previously the GHCi linker assumed
there would always be exactly one symbol table and exactly one string
table. In fact, in ELF object files there is no such limitation, instead
each section points to the other sections it needs, in particular
relocation sections have a link to the symbol table section they use and
symbol table sections have a link to the corresponding string table.
So instead of assuming there will always be a global symbol and string
table, all we have to do is validate and follow these links. Then, when
we encounter an empty object file that has no symbols then we handle it
correctly, because since it's empty we never process any relocations and
so never have to follow any links to non-existant symbol tables.

Also, in the case where an object is fully stripped, we can now detect
this more reliably and emit a more helpful error message, e.g:

libHSghc-7.1.20110509.a(DsMeta.o): relocation section #2 has no symbol table
This object file has probably been fully striped. Such files cannot be linked.

Merge branch monad-comp onto master

This patch implements monad comprehensions, Trac #4370.
Thanks to Nils Schweinsberg for doing most of the heavy lifting.

I did quite a lot of related refactoring as well.  Notably:

* Combined TransformStmt and GroupStmt into a single
  constructor TransStmt; they share a lot of code.
  I also made TransStmt into a record; it has a lot of fields.

* Remove the "result expression" field of HsDo, and instead
  implement LastStmt, which is expected to be at the end
  of a list of Stmts

* Generalise and tidy up the typechecking of monad comprehensions

* Do-notation in arrows is marked with HsStmtContext = ArrowExpr

* tcMDoStmt (which was only used for arrows) is moved
  to TcArrows, and renamed tcArrDoStmt

* Improved documentation in the user manual

* Lots of other minor changes

Remove HsNumTy and TypePati.

They belonged to the old generic deriving mechanism, so they can go. Adapted a lot of code as a consequence.
