<pre>If multiple ELF objects are passed to llvm-readelf (either independently or
within an archive) when dumping symbol tables, the index of the symbols
continues incrementing across all inputs:
C:\Work\TempWork> llvm-readelf -s bar.o bar2.o
File: bar.o
Symbol table '.symtab' contains 4 entries:
Num: Value Size Type Bind Vis Ndx Name
0: 0000000000000000 0 NOTYPE LOCAL DEFAULT UND
1: 0000000000000000 0 FILE LOCAL DEFAULT ABS bar.cpp
2: 0000000000000000 4 OBJECT GLOBAL HIDDEN 4 bar
3: 0000000000000000 4 OBJECT GLOBAL HIDDEN 3 baz
File: bar2.o
Symbol table '.symtab' contains 4 entries:
Num: Value Size Type Bind Vis Ndx Name
4: 0000000000000000 0 NOTYPE LOCAL DEFAULT UND
5: 0000000000000000 0 FILE LOCAL DEFAULT ABS bar2.cpp
6: 0000000000000000 4 OBJECT GLOBAL HIDDEN 3 foo
7: 0000000000000000 4 OBJECT GLOBAL HIDDEN 4 four
This is incorrect - the "Num" column should start from 0 at the start of every
section printing (this is what GNU readelf does). The problem is the use of a
local static variable in the printSymbol function which is used to track the
index - nothing resets this for regular object files, and it only gets reset
when switching between dumping static and dynamic symbol tables.
The fix will require a little bit of refactoring, but it should be a fairly
simple thing to do.</pre>
