GreenHills - small data area overflow

Question

I'm hoping maybe someone has a quick answer for this but essentially when I turn on optimizations, I get the following error:

[elxr] (error) small data area overflow: 0xfff9f6fc (signed) didn't fit in 16 bits while performing relocation in file test_main.o at location sti_13_test_main_cpp_252229d3+0xc, to reference symbol oe_init_intconn

A similar error occurs when I put in this linker directive as well:

-auto_sda

Their manual doesn't make any mention of this linker error. I'm using Integrity 5.10

Answer 1

After doing some research, it's possible that linking libraries that all don't use the SDA option might have this conflict. Since I don't have control over how those libraries are built, at the moment I've applied the following flags to my GPJ that seemed to resolve the issue:

-Onolink
-no_auto_sda
-nothreshold

Note that these options disable all linker optimizations and disable the SDA option completely.
