(FIXME): Unfortunately, we are not that lucky: it turns out that the

when it is entered (somread.c::som_symtab_read()) it can happen that

if the type of the symbol (from the som) is Entry, and the symbol is

in a shared library, then it can also be a trampoline. This would

be OK, except that I believe the way they decide if we are ina shared library
|
|
|
|
|
does not work. SOOOO..., even if we have a regular function w/o trampolines
|
|
|
|
|
its minimal symbol can be assigned type mst_solib_trampoline.
|
|
|
|
|
Also, if we find that the symbol is a real stub, then we fix the unwind
|

descriptor, and define the stub type to be EXPORT.

That's the branch from an

|
|
|
import stub to an export stub.
|
|
|
|
|
|
|
|
|
|
It is impossible to determine the target of the branch via
|
|
|
|
|
simple examination of instructions and/or data (consider
|
|
|
|
|
that the address in the plabel may be the address of the
|
|
|
|
|
bind-on-reference routine in the dynamic loader).
|
|
|
|
|
|
|
|
|
|
So we have try an alternative approach.
|
|
|
|
|
|
|
|
|
|
Get the name of the symbol at our current location; it should
|
|
|
|
|
be a stub symbol with the same name as the symbol in the
|
|
|
|
|
shared library.
|
|
|
|
|
|
|
|
|
|
Then lookup a minimal symbol with the same name; we should
|
|
|
|
|
get the minimal symbol for the target routine in the shared
|
|
|
|
|
library as those take precedence of import/export stubs. */

/* elz: Used to lookup a symbol in the shared libraries.
|
|
|
|
|
This function calls shl_findsym, indirectly through a
|
|
|
|
|
call to __d_shl_get. __d_shl_get is in end.c, which is always
|
|
|
|
|
linked in by the hp compilers/linkers.
|
|
|
|
|
The call to shl_findsym cannot be made directly because it needs
|
|
|
|
|
to be active in target address space.
|
|
|
|
|
inputs: - minimal symbol pointer for the function we want to look up
|
|
|
|
|
- address in target space of the descriptor for the library
|
|
|
|
|
where we want to look the symbol up.
|
|
|
|
|
This address is retrieved using the
|
|
|
|
|
som_solib_get_solib_by_pc function (somsolib.c).
|
|
|
|
|
output: - real address in the library of the function.
|
|
|
|
|
note: the handle can be null, in which case shl_findsym will look for
|
|
|
|
|
the symbol in all the loaded shared libraries.
|
|
|
|
|
files to look at if you need reference on this stuff:

/* In order to make an interspace call, we need to go through a stub.
|
|
|
|
|
gcc supplies an appropriate stub called "__gcc_plt_call", however, if
|
|
|
|
|
an application is compiled with HP compilers then this stub is not
|
|
|
|
|
available. We used to fallback to "__d_plt_call", however that stub
|
|
|
|
|
is not entirely useful for us because it doesn't do an interspace
|
|
|
|
|
return back to the caller. Also, on hppa64-hpux, there is no
|
|
|
|
|
__gcc_plt_call available. In order to keep the code uniform, we
|
|
|
|
|
instead don't use either of these stubs, but instead write our own
|
|
|
|
|
onto the stack.
|
|
|
|
|
|
|
|
|
|
A problem arises since the stack is located in a different space than
|
|
|
|
|
code, so in order to branch to a stack stub, we will need to do an
|
|
|
|
|
interspace branch. Previous versions of gdb did this by modifying code
|
|
|
|
|
at the current pc and doing single-stepping to set the pcsq. Since this
|
|
|
|
|
is highly undesirable, we use a different scheme:
|
|
|
|
|
|
|
|
|
|
All we really need to do the branch to the stub is a short instruction
|
|
|
|
|
sequence like this:
|
|
|
|
|
|
|
|
|
|
PA1.1:
|
|
|
|
|
ldsid (rX),r1
|
|
|
|
|
mtsp r1,sr0
|
|
|
|
|
be,n (sr0,rX)
|
|
|
|
|
|
|
|
|
|
PA2.0:
|
|
|
|
|
bve,n (sr0,rX)
|
|
|
|
|
|
|
|
|
|
Instead of writing these sequences ourselves, we can find it in
|
|
|
|
|
the instruction stream that belongs to the current space. While this
|
|
|
|
|
seems difficult at first, we are actually guaranteed to find the sequences
|
|
|
|
|
in several places:
|
|
|
|
|
|
|
|
|
|
For 32-bit code:
|
|
|
|
|
- in export stubs for shared libraries
|
|
|
|
|
- in the "noshlibs" routine in the main module
|
|
|
|
|
|
|
|
|
|
For 64-bit code:
|
|
|
|
|
- at the end of each "regular" function
|
|
|
|
|
|
|
|
|
|
We cache the address of these sequences in the objfile's private data
|
|
|
|
|
since these operations can potentially be quite expensive.
|
|
|
|
|
|
|
|
|
|
So, what we do is:
|
|
|
|
|
- write a stack trampoline
|
|
|
|
|
- look for a suitable instruction sequence in the current space
|
|
|
|
|
- point the sequence at the trampoline
|
|
|
|
|
- set the return address of the trampoline to the current space
|
|
|
|
|
(see hppa_hpux_find_dummy_call_bpaddr)
|
|
|
|
|
- set the continuing address of the "dummy code" as the sequence.
