OpenRISC port Issue #3: Binary header issue with -nostdlib/-nostartfiles flags #197

Closed madhu2000u closed 1 month ago

madhu2000u commented 2 months ago

Part of OpenRISC port.

Issue:

When running OpenRISC toolchain with -nostdlibs and -nostartfiles as per line 1348, the benchmark_size.py reports "Binary does not have program header" for all binaries. I understand stdlibs and start files are not added to remove libs and C runtime from binary, but then shouldn't it still run for the bare metal binary generated as well? (As mentioned before, or1k-elf is a bare metal toolchain based on newlib).

Current soln:

I am excluding these flags for OpenRISC toolchain compilation.

I wanted your guidance on the working of this part of the tool.

Embench moving to 2.0. Issue still exists. Could be issue with toolchain as well. Opening if issue persists as part of Embench 2.0
