Yes, there are `jal` instruction, `j` pseudoinstruction or conditional branch instruction in these .S files in the following links… Also, there errors generate after I add some new code package into my whole project. Before that it can be built correctly even with `-ggdb -O0` options.  
[context\_gcc.S](https://github.com/RT-Thread/rt-thread/blob/master/libcpu/risc-v/common/context_gcc.S)  
[interrupt\_gcc.S](https://github.com/RT-Thread/rt-thread/blob/master/libcpu/risc-v/k210/interrupt_gcc.S)  
[startup\_gcc.S](https://github.com/RT-Thread/rt-thread/blob/master/libcpu/risc-v/k210/startup_gcc.S)

Do these errors mean that the targets of these instructions are beyond the address range they can access? And when options `-Os` is used, the size of the code is optimized to a smaller one so that those targets fall into the address range of those instructions again? If so, how should I fix it?

Sorry I cannot provide a complete testcase now.
