Linker --fix-v4bx problem

[Gary Partis]

Hello

I am using GNU ld version 2.31.1 to target ARMv3 (ARM610/710) processors. 
Primarily, GCC's libgcc contains "BX LR" instructions which we want changed to 
"MOV PC,LR" so to be compatible with older processors, but after running the 
linker with the "--fix-vxb4" directive the BX instructions are still there (we 
use objdump to disassemble the resultant ELF file to check).

Are we missing something really obvious or is the "--fix-v4bx" directive broken 
in some way?

Thanks in advance.

Kind regards

Gary Partis
