Do not try to insert local variable info to a DIE used for function declaration.

Relax assertion. In optimized code, it is possible that first instruction is coming from a inlined function.
This fixes PR7596 .

Reuse DIEInteger for 1. This is frequently used while emitting an attribute using dwarf::DW_FORM_flag form.

Keep track of abstract subprogram DIEs.

This is a regression caused by r106792 and caught by gdb testsuite.

Add variables into a scope before constructing scope DIE otherwise variables won't be included DIE tree.

DBG_VALUE machine instruction pointing to undefined register for a variable justify a separate scope if the variable is inlined function's argument.

switch from this:

  if (TimePassesIsEnabled) {
    NamedRegionTimer T(Name, GroupName);
    do_something();
  } else {
    do_something(); // duplicate the code, this time without a timer!
  }

to this:

  {
    NamedRegionTimer T(Name, GroupName, TimePassesIsEnabled);
    do_something();
  }

This speeds up local variable handling in DwarfDebug.

inlined function's arguments need a label to mark the start point because they are not directly attached to current function.

llvm-svn: 104848

llvm-svn: 104841

llvm-svn: 104785

There is no need to force an line number entry (using previous location) for a temp label at unknown location.

llvm-svn: 104740

Identify instructions, that needs a label to mark debug info entity, in advance. This simplifies beginScope().

This is used to track variable information.
