riscv32-unknown-elf/bin/ld: can't relax section: No more archived files #15

Closed deepsrc closed 6 years ago

This failure is generated during the link for the elf, when compress instructions are mixed with non compressed instructions in a .s file

On debugging, it was found that the failure occurs only when the end of the instruction buffer is not aligned to 4 bytes i.e. the number of compressed instructions in the .s file is odd. In order to make forward progress, we have added a c.nop at the end of .s file whenever the total number of compressed instructions generated is an odd number

Could you provide a basic example so that we reproduce the issue ?

deepsrc commented 6 years ago

Sorry, I didn't see the update. I will reproduce the issue and send you the files.
