[Bug ld/1543] New: LD very slow especially when linking C++ object files on alpha

[uwe at thetaphi dot de]

This bug occurred some time after the release of 2.16.1. Because this version 
had a bug that makes it impossible to link files generated by gcc-4.0 for the 
alpha platform, debian unstable contains a newer version from CVS.

When linking especially C++ files generated by GCC 4.0 (not tested with earlier 
versions of GCC) ld uses about 100% CPU and takes for a simple executable of 
about 4 MBytes size about 2 hours (Alphaststion 500/500). We decided to run 
oprofile on ld and it is spending all it's time in 
bfd_elf_size_dynsym_hash_dynstr. At this point 99.9998% of time is being spent 
in that function.

I wrote this bug report because I do not exspect the debian developers to fix 
that for a rarely used platform like alpha.
