This script is designed to ignore lines that don't follow the expected
format, but it is widely known that the output format of readelf utility
from the binutils project can be quite unreliable. The output format
may vary on certain architectures and ELFs created with certain build
tools may contain symbols with peculiar bits that affect the output.
Here is a couple of examples illustrating these issues:
* On PowerPC, ELF symbols frequently include the localentry bit.
For instance:
$ readelf --wide --dyn-syms /lib64/libcrypto.so.1.1 | grep ASN1_VISIBLESTRING_new
157: 00000000000938c0 60 FUNC GLOBAL DEFAULT [<localentry>: 8] 11 ASN1_VISIBLESTRING_new@@OPENSSL_1_1_0
* On x86_64, a proprietary blob /usr/lib64/libjcPKCS11ds.so (distributed
as an ELF) and on armh /usr/lib/libLLVM-16.so, contain symbols with
OS-specific bits:
$ readelf --wide --dyn-syms /usr/lib64/libjcPKCS11ds.so | grep _ZNSt7collateIwE2idE
2572: 00000000002df9c8 8 OBJECT <OS specific>: 10 DEFAULT 26 _ZNSt7collateIwE2idE
$ readelf --wide --dyn-syms /usr/lib/libLLVM-16.so | grep _ZN4llvm13AllAnalysesOnINS_6ModuleEE6SetKeyE
45060: 05af0478 8 OBJECT <OS specific>: 10 DEFAULT 26 _ZN4llvm13AllAnalysesOnINS_6ModuleEE6SetKeyE@@LLVM_16
The issue related to PowerPC localentry bits was resolved in the commit
4f4a1d146 ("lib.prov, lib.req: enhance ProvidedSymbols") a long time
ago. The issue related to OS-specific bits was discovered recently [1].
Instead of attempting to resolve the output issues of binutils' readelf
utility concerning OS-specific bits, it is more convenient to use
readelf from elfutils. It has more reliable output (including the
handling of the cases described earlier) and is extensively utilized
within the project anyway.
