[Bug tools/21522] New: eu-strip generates empty output if there is nothing to do
https://sourceware.org/bugzilla/show_bug.cgi?id=21522
Bug ID: 21522
Summary: eu-strip generates empty output if there is nothing to
do
Product: elfutils
Version: unspecified
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: tools
Assignee: unassigned at sourceware dot org
Reporter: paulo.cesar.pereira.de.andrade at gmail dot com
CC: elfutils-devel at sourceware dot org
Target Milestone: ---
Steps to reproduce:
$ cat test.c
int main() { return 1; }
$ gcc test.c
$ eu-strip -g -o test ./a.out
The "test" file will have zero bytes.
This happens because of the test in src/strip.c:
/* Test whether we are doing anything at all. */
if (cnt == idx)
/* Nope, all removable sections are already gone. */
goto fail_close;
Note also that, if the test is removed, it still
generates a different binary, so, the test is incomplete,
or should be removed.

[Bug tools/21525] New: Multiple .shstrtab sections since eu-readelf 0.166
https://sourceware.org/bugzilla/show_bug.cgi?id=21525
Bug ID: 21525
Summary: Multiple .shstrtab sections since eu-readelf 0.166
Product: elfutils
Version: unspecified
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: tools
Assignee: unassigned at sourceware dot org

I understand this is not really a bug, but it generates an
output more complex than it should be, and confuses tools like
patchelf.
Example:
$ cat test.c
int main() { return 1; }
$ gcc -g test.c
$ eu-strip -g a.out
$ eu-readelf -S a.out | grep .shstrtab | wc -l
The extra section appears useless at least on the
sense of a very simple test case.
The issue started with this commit:
