--- Comment #6 from Tom Tromey <tromey at sourceware dot org> ---
The issue in that regression seems to be that the
symbol is defined for C, not Ada, so it isn't matched.
Maybe the DWARF reader should be creating an Ada
symbol here.

 <2><154e>: Abbrev Number: 3 (DW_TAG_subprogram)
    <154f>   DW_AT_external    : 1
    <154f>   DW_AT_name        : (indirect string, offset: 0x21d8):
foo_h731_021__c_func
    <1553>   DW_AT_decl_file   : 1
    <1554>   DW_AT_decl_line   : 17
    <1555>   DW_AT_decl_column : 14
    <1556>   DW_AT_linkage_name: (indirect string, offset: 0x201d):
MixedCaseFunc
    <155a>   DW_AT_declaration : 1


I didn't debug here but I assume the "declaration" setting
is preventing this.  But maybe it shouldn't when the name
and the mangled name are clearly different.


Or maybe I should just try to understand why the patch in
question could even cause this regression.  It doesn't seem
like that should be possible.
