tests for the other bugs would have been nice; unfortunately,  they are rather big and trying to minimise them was not possible....

we now can AKD withloops with empty results as well :-)

functions would only be "opened up" for improving the inferred return type if they were still instances of a wrapper function. Isolated instances that had been dispatched and their wrapper functions deleted would never be improved wrt their return type again.
This could lead to a situation where the inferred type was AKD but the official return type was AUDGZ/AUD.
This incompatability then led to descriptor mismatches in the generated code which led to uninitialised dim/shape info.
Erratic runtime behaviour was the consequence!

noinline
int[.] offset2idx (int offset, int[.] shp)
{
    res = [];
    for( i=2; _ge_SxS_( i, 0); i=_sub_SxS_(i, 1)) {
        res = _cat_VxV_ (offset , res);                         // offset should be in brackets but the TC would previously choke on it :-)
    }
    return res;
}

int main()
{
   vect = offset2idx ( 8, [3,4,3]);

   return _sel_VxA_([0], vect);
}

in particular WLBSC needs to be run directly before WLTRA! added another run in phase wlt....

Eradicate old types

funs done:
MakeArgNode
MakeBasetypeArg

This is important since the additions of Rouland do not allow for eexternals to be nested without screwing the code generation up......
We can tackle this later!

Fixing typo in the Makefile.

See merge request !130

actually not much was missing here. However, the treatment of T_hidden received a massive conceptual overhaul.
This was triggered by the observation that SACarg needs to be treated like a nested data structure.....
When ironing that out in compile.c we can equally well make sure we add proper support for nesting throughout....

Fix mt fold sbs

See merge request !129

streamlined the explanation; added a section on the implementation and extracted the two Handle-functions as helpes...

and put quite some more detail into the main comment of MTSPMDF.
This is now feature complete....

started re-writing SPMDF lifting to include a dec_rc on the neutral element after the lifted function

By setting the rc in the stack copy of the descriptor to 2 we are safe now. I also injected tracing info so that it easier to see what is going on just from the trace.
As a consequence of this, the MT version now leaks one copy of the neutral element! This needs another fix.
Finally, I added some comments in MTRMI to explain what exactly it does and to understand that traversal more quickly :-)

[hwloc] fix error on no hwloc.h header

See merge request !127

The declarations in cpubind.h still need the hwloc.h header file,
regardless if we are compiling with HWLOC support or not. This commit
fixes this.
