Hi Gary,

> 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).

It could be either situation.  Please can you file a bug report here, and include a test case:

Thanks.
