Bug ID: 22250
Summary: readelf should support --dwarf-start and --dwarf-depth
Product: elfutils
Version: unspecified
Status: NEW
Severity: normal
Priority: P2
Component: tools
Assignee: unassigned at sourceware dot org
Reporter: tromey at sourceware dot org
CC: elfutils-devel at sourceware dot org
Target Milestone: ---
objdump supports --dwarf-start and --dwarf-depth options.
--dwarf-start specifies the DIE at which to begin dumping.
--dwarf-depth specifies how many levels down to print; if
there are more levels it just prints "...", like:
<0><2174>: Abbrev Number: 1 (DW_TAG_compile_unit)
<2175> DW_AT_producer : (indirect string, offset: 0x0): clang LLVM
(rustc version 1.20.0 (f3d6973f4 2017-08-27))
<2179> DW_AT_language : 28 (Unknown: 1c)
<217b> DW_AT_name : (indirect string, offset: 0x1621):
/checkout/src/libstd/lib.rs
<217f> DW_AT_stmt_list : 0x9f2
<2183> DW_AT_comp_dir : (indirect string, offset: 0x163d):
/checkout/obj
<2187> DW_AT_low_pc : 0x0
<218f> DW_AT_ranges : 0x2be80
<1><2193>: ...
These are handy for investigating large files with dwarf-mode that
is in binutils.
