Bug ID: 18288
Summary: linker -s output suboptimal
Product: binutils
Version: 2.25
Status: NEW
Severity: normal
Priority: P2
Component: binutils
Assignee: unassigned at sourceware dot org
Reporter: dilyan.palauzov at aegee dot org
I have binutils 2.25/gold 1.11. I compile a program with `ld.gold -s', do
`readelf --all` on in. Then I `strip' the program and do `readelf --all' on
the results. Then I compare the outputs of the two `readelf' invocations. I
expected these to be identical. However, they are not, here the diff:
--- r-gold-stripped 2015-04-21 12:00:29.206029031 +0000
+++ r-gold-orig 2015-04-21 12:00:22.532028940 +0000

Version: 0x1
Entry point address: 0x40c084
Start of program headers: 64 (bytes into file)
- Start of section headers: 469920 (bytes into file)
+ Start of section headers: 469928 (bytes into file)
Flags: 0x0
Size of this header: 64 (bytes)
Size of program headers: 56 (bytes)
The sizes also differ:
471648 - stripped
471656 - unstripped
Then I did the same procedure with the ld.bfd - linker. The numbers coincide
with ld.gold.
To my understanding the linker option -s is supposed to make running `strip'
after compiling superfluous. But it doesn't, as strip reduces the file size
further, without doing anything else.
Hence I consider this as bug (in both ld and gold).
