Bug ID: 40630
Summary: Improve --string-dump invalid section error message
Product: tools
Version: trunk
Hardware: PC
OS: Windows NT
Status: NEW
Severity: enhancement
Priority: P
Component: llvm-readobj
Assignee: unassignedbugs at nondot.org
Reporter: jh7370.2008 at my.bristol.ac.uk
CC: jh7370.2008 at my.bristol.ac.uk, llvm-bugs at lists.llvm.org
Currently, if you do --string-dump (or potentially other similar options), with
an invalid input (e.g. an out-of-range section index or section that does not
exist), llvm-readobj produces the error "Error reading file: invalid section
reference":
C:\Work>llvm-readobj --string-dump=does_not_exist foo.o
Format: ELF64-x86-64
Arch: x86_64
AddressSize: 64bit
LoadName:
Error reading file: invalid section reference.
C:\Work>
There are two problems with this error message. Firstly, it incorrectly claims
that there was a problem reading the file, where really the problem was a bad
input. Secondly, the error message makes no reference to the source of the
reference or why it is bad. Both these aspects should be improved.
