FYI, I've used this mirror:
https://github.com/bminor/binutils-gdb/blob/master/bfd/elfnn-riscv.c
Here _bfd_riscv_elf_merge_private_bfd_data starts at line 3781, so it's not
exactly the same as yours either, but th

Hi Nelson,
I feel disturbance in the force... I'm using ftpmirror.gnu.org, which redirects
to a regional mirror. The 2.35 source I can download from there definitely
differs from yours, because according to your p

Yes, agreed. The other part being not been able to s

But it does invent it, that's the problem! "ld" should just use the default ABI
for the platform, the same as all the other tool use. Not inventing up

> That's the point. Using ld -b binary is not a good way to wrap binary blobs.
Bad point! Forcing additional assembly on all language and architecture
combinations? An unacceptable additional complexity to the bui

Or let me rephrase: ld generating an Elf header with an emulation that it

No assembler used in this project.
FYI, this works with x86_64 and aarch64 only risv64 affected. I also have C++,
Pascal, Rust versions of kernel.c, those must be linked with font.o too, so
this needs to be a langu

Dear binutils developers,
I've found an issue with the latest GNU ld in binutils about generating RiscV64
ELF headers.
