Bug ID: 31605
Summary: [readelf, -wL] Highlight empty address range
Product: binutils
Version: unspecified
Status: NEW
Severity: enhancement
Priority: P2
Component: binutils
Assignee: unassigned at sourceware dot org
Reporter: vries at gcc dot gnu.org
Target Milestone: ---
Consider gdb test-case gdb.dwarf2/dw2-epilogue-begin.exp.
With readelf -wL <exec>, we have:
...
File name Line number Starting address View Stmt
dw2-epilogue-begin.c 44 0x4101e8 x
dw2-epilogue-begin.c 47 0x4101ec x
dw2-epilogue-begin.c - 0x4101ec
...
The entry for line 47 has an empty address range (and consequently gdb ignores
it), but it's not obvious from the readelf output.
I wonder if making this clear somehow using an annotation would be a good idea.
Say:
...
File name Line number Starting address View Stmt
dw2-epilogue-begin.c 44 0x4101e8 x
dw2-epilogue-begin.c 47 ~0x4101ec x
dw2-epilogue-begin.c - 0x4101ec
...
Or displaying the address in parentheses.
