Change seems fine to me. Can we add a test for it? |
|
Also, this is a binary compatibility break, so we'll need to notify folks to rebuild their stuff |
This must match other objects that have `EF_RISCV_RVE` set in their ELF header. CHERIoT targets use XLEN=16 (E).
|
I've added a test that checks the flags for specifically the cheriot CPU and ABI |
|
I’d probably hold off merging this until after we’ve fixed #9. We need to be reporting Xcheriotv1 as an extension and putting this in the ELF as well. |
|
This will be subsumed by #140 |

Perfect, thanks for your help |

The
EF_RISCV_RVEflag in ELF headers must match for all objects when linking. CHERIoT targets useXLEN=1616 integer registers (E), so I think this should be set.Tested by linking to objects that did have the
RVEflag set. Before this patch the linker complained about the mismatch:
