1) install libantlr4-runtime-devel and perf.
2) 

3) cat > main.cpp <<EOF
#include <cstdio>
#include <antlr4-runtime.h>

int main()
{
        for (int a = 0; a < 10000000; a++)
                antlr4::ANTLRInputStream input("/dev/null");
}
EOF

4) cat > Makefile <<EOF
CXXFLAGS=-g -Wall -I/usr/include/antlr4-runtime -Wno-attributes -mfentry
LDLIBS=-lantlr4-runtime

all: main
EOF

5) make && perf record -g ./main

6) perf report -g

7) symbols of antlr library are shown in hexa (not resolved), despite debuginfo
is installed

Perf fails here:
https://github.com/torvalds/linux/blob/9f1abbe97c08ba7ed609791627533a805a1b2c66/tools/perf/util/symbol-elf.c#L1229

It walks through all symbols in .symtab of:
/usr/lib/debug/usr/lib64/libantlr4-runtime.so.4.8-4.8-1.4.x86_64.debug

and resolves the symbol addresses into names there. First, it obtains the
section a symbol is in -- sym.st_shndx (like 13th for .text, 25th for .data,
...) from:
/usr/lib64/libantlr4-runtime.so.4.8
(i.e. not the .debug). And then it uses the section header to eliminate ASLR.

But there are also symbols like these:
 10305: 0000000000955fa4     0 NOTYPE  LOCAL  DEFAULT   29
Predicate.cpp.2bc410e7

There is no section 29 in libantlr4-runtime.so.4.8, it's only in
libantlr4-runtime.so.4.8-4.8-1.4.x86_64.debug (it's .debuginfo there).

Now, I don't know whose bug is this. Is it perf or the dwarf separator in rpm?

BTW are the section numbers supposed to be the same in both elfs?
