My full pascal code is on Github
https://github.com/TYDQSoft/UEFIPascalOS
I have run the buildall.sh to compile x86_64 arch,cross compile
aarch64 arch and loongarch64 arch.
buildall.sh:

aarch64,but compile in loongarch64 it give me error:
Error: Compilation raised exception internally
An unhandled exception occurred at $000000000047C8B3:
EListError: List index exceeds bounds (0)
  $000000000047C8B3
So does anyone know the same code only can't be compiled in
loongarch64 mode?(I have tested x86_64(host),aarch64,loongarch64)
And does anyone know how to build aarch64 efi and loongarch64 efi
correctly?

I updated the binutils but the same error exists and I don't know
why?Is it the internal error in fpc or my code is wrong?

loongarch is not a common platform. If your code works on AARCH it is
likely that loongarch  is at fault here.
BTW, I find it commendable that your uefi compiler works, albeit not
everywhere. That is a great achievement on its own!

Yeah,I hope as the fpc updates the support of loongarch64 will be
stable and normally.
However,I cannot install clang cross compiler in x64 to aarch64
because my computer RAM is not enough and I need to change the way to
generate efi files like using hacks  as gnu-efi do.The gnu-efi linker
script is not suitable for pascal compiled objects because the
exported file is too large.So it must have another way to solve the
problem that elf to efi(I have tested the elf2efi in github,It is
useless as it reminds .hash unrecognized).
