f799efdedc The DIBuilder class is just a wrapper around debug info creation 
(a.k.a. MDNodes). The module doesn't belong in Analysis. Move it to the VMCore
instead.

4d358b55fa Have getOrCreateSubprogramDIE store the DIE for a subprogram 
definition in the map before calling itself to retrieve the
DIE for the declaration.  Without this change, if this causes
getOrCreateSubprogramDIE to be recursively called on the definition,
it will create multiple DIEs for that definition.  Fixes PR12831.

7dd54fb695 Revert the removal of DW_AT_MIPS_linkage_name when we aren't putting 
out the DW_AT_name. Older gdbs unfortunately still use it to

a9916d0296 Remove the DW_AT_MIPS_linkage name attribute when we don't need it

107e8ec30d DISubrange supports unsigned lower/upper array bounds, so let's not fake it in the end while emitting DWARF. If a FE needs to encode signed lower/upper array bounds then we need to extend DISubrange or ad DISignedSubrange.

29ccdd8207 Dwarf: [PR11022] Fix emitting DW_AT_const_value(>i64), to be host-endian-neutral. 
Don't assume APInt::getRawData() would hold target-aware endianness nor host-compliant endianness. rawdata[0] holds most lower i64, even on big endian host.

FIXME: Add a testcase for big endian target.

FIXME: Ditto on CompileUnit::addConstantFPValue() ?

5e6b65cf0d Do not unnecessarily use AT_specification DIE because it does not add any value. 
Few weeks ago, llvm completely inverted the debug info graph. Earlier each debug info node used to keep track of its compile unit, now compile unit keeps track of important nodes. One impact of this change is that the global variable's do not have any context, which should be checked before deciding to use AT_specification DIE.

eb1bb4e419 Until now all debug info MDNodes referred to a root MDNode, a compile unit. This simplified handling of these needs in dwarf writer. However, one side effect of this is that during link time optimization all these MDNodes are _not_ uniqued. In other words there will be N number of MDNodes describing "int", "char" and all other types, which would suddenly grow when each object file starts using libraries like STL. 
MDNodes graph structure such that compiler unit keeps track of important MDNodes and update dwarf writer to process mdnodes top-down instead of bottom up.
