[lldb-dev] Linux issues where I am not getting breakpoints...

[Greg Clayton via lldb-dev]

I have added some logging to a program that is not hitting breakpoints with LLDB top of tree SVN. An older lldb 3.8 hits the breakpoint just fine. I placed some logging in LLDB:

ModuleSP DynamicLoader::LoadModuleAtAddress(const FileSpec &file,
                                            addr_t link_map_addr,
                                            addr_t base_addr,
                                            bool base_addr_is_offset) {
  printf("%s: lma = 0x%16.16llx, ba = 0x%16.16llx, baio = %i\n", file.GetPath().c_str(), link_map_addr, base_addr, base_addr_is_offset);


This is called by DynamicLoaderPOSIXDYLD::LoadAllCurrentModules().

My problem is I see:

[vdso]: lma = 0xffffffffffffffff, ba = 0x00007ffff7ffa000, baio = 0
linux-vdso.so.1: lma = 0x00007ffff7ffe6e0, ba = 0x00007ffff7ffa000, baio = 1
/tmp/liba.so: lma = 0x00007ffff7ff66a8, ba = 0x00007ffff7e30000, baio = 1
8 locations added to breakpoint 1
/tmp/libb.so: lma = 0x00007ffff7e2f000, ba = 0x00007ffff7d43000, baio = 1

/tmp/libd.so: lma = 0x00007ffff7e2f000, ba = 0x00007ffff7d43000, baio = 1


Note that I see program output _during_ the messages that are showing that shared libraries are being loaded? I would assume we are loading shared libraries synchronously, but the log seems to indicated otherwise. 

If anyone knows anything on this subject please let me know...
