ld -shared -Bsymbolic will reduce number of dynamic relocations in
a shared library. Unfortunately, it won't work correctly with C++
exception and maybe other language features.
However, I think it is possible to make -shared -Bsymbolic to work
for C++ by providing a way to specify a list of symbo

I think first you should be more specific about what you are trying to do.

are there any platforms where gcc doesn't support 8-byte ints?

This would make life easier for Fortran, for example, because we

to bother with checks for the presence of KIND=8 integers.

Thanks for the offer! Yes, I think that
At present, we have 160 serious regressions open against mainline (which
will become 4.2). (I've downgraded many of Volker's reports about ICEs
after valid error messages to P4, following Jason's recommendation.
Upon reflection, I think that's the right thing to do; although robust

The GCC internals explicitly introduced code manipulation APIs in TREE
representation (bsi_insert_before, bsi_remove etc). But I did not see the
equivalent for RTL representation.
Say, I want to enable a counter for a n-depth-nested loop. For example, I
