Does not work on Arm (32bit)

[derekatkins]

Hi,
Trying to run this on an Arm platform and it's not working. When I run it I get the following:

./mod-elf-symbol -o foo.o -c foo --completestr=asdf
+++++++++++++++++++++++++++++++++ Started replace-symbols-name Program

The object files to modify are:
(0) foo.o

Complete Symbols planned on changing:
(0) foo --> asdf

SUCCESS: The ELF type is that of an relocatable. (foo.o)
mod-elf-symbol: src/mod-elf-symbol.c:736: main: Assertion `findSymtabAndStrtabAndShdr(objList[i], ehdr, &shdr, &symtab, &strtab) != -1' failed.
Aborted

If I compile mod-elf-symbol on x86 and run it against the Arm foo.o, I get:

SUCCESS: The ELF type is that of an relocatable. (foo.o)
readall: end of file

Just for the record, file foo.o returns:

foo.o: ELF 32-bit LSB relocatable, ARM, EABI5 version 1 (SYSV), with debug_info, not stripped

and objdump -t reports:

foo.o:     file format elf32-little

SYMBOL TABLE:
...

Also for the record, running file and objdump -t against an x86 object file gives me:

mod-elf-symbol.o: ELF 64-bit LSB relocatable, x86-64, version 1 (SYSV), with debug_info, not stripped
...
mod-elf-symbol.o:     file format elf64-x8
6-64

SYMBOL TABLE:
0000000000000000 l    df *ABS*	0000000000000000 mod-elf-symbol.c
0000000000000000 l    d  .text	0000000000000000 .text
...

Could this be a 32- vs 64-bit issue? It is unlikely to be a byte-order issue, I don't think -- both files report LSB.

Okay, one more comment; I replaced all instances of Elf64_ with Elf32_ and recompiled, and then it seems to have worked for my Arm-32 file:

...
SUCCESS: The ELF type is that of an relocatable. (foo.o)
In file foo.o symbols checked:
	Complete Symbols
		symbol: foo  |  sym->st_value: 0xbc9

Finished replace-symbols-name Program +++++++++++++++++++++++++++++++++

I am working with someone to verify that the result still work, and will update once those tests are done.

For the record, it does work with the change.
