hrev45891 adds 1 changeset to branch 'master'
old head: 6dbd3ed18ca5c5fc49fa897083d156da8131d6bd
new head: 8e80ec6aaaf058e7fe032e1b78201344e9b665d8
overview: http://cgit.haiku-os.org/haiku/log/?qt=range&q=8e80ec6+%5E6dbd3ed
----------------------------------------------------------------------------
8e80ec6: Debugger: Handle some more v4 attributes.
- DIECompileUnit can also be marked with DW_AT_main_subprogram to
indicate that the main program resides within that particular unit.
- DIEBaseType and DIEMember now have the additional attribute
DW_AT_data_bit_offset which defines the offset in a somewhat different
manner than DWARF2/3's DW_AT_bit_offset, and deprecates the latter.
Unused/untested for the moment, as gcc 4.7.3 doesn't yet appear to be
generating either of the above attributes.
