Can't load elf file into spike

msyksphinz-self commented 1 year ago

Problem: Got a load error when I try to load and run the ELF file in the repository into riscv-isa-sim(spike).
Reproduction:

spike --isa=rv64imc -l rv_i/rvi_compute_register_register/rvi_compute_register_register_1

Access exception occurred while loading payload rv_i/rvi_compute_register_register/rvi_compute_register_register_1:
Memory address 0x726000 is invalid

Investigation: The address of 0x726000 is defined in program header and put the .os_data section etc. I don't know what's the purpose of the section.

Following is the result of riscv64-unknown-elf-readelf -a

These tests access the addresses in the entire available virtual (up to 57-bits) and physical (52-bits) address space. We have tweaked memory ranges for Spike internally to allow these tests to run on modified Spike. We should open source the fork of Spike to provide you the changes.

This has been fixed with the latest release and we have also switched to the public version of Spike. Please give it a try to the latest tests.

Please reopen if you see any fails.
