Add AArch64 Big Endian Variants using FVP models #554

Open simpal01 opened 1 week ago

simpal01 commented 1 week ago

This patch add new aarch64 big endian library variants.

  1. aarch64_be
  2. aarch64_be_exn_rtti

QEMU's doesn't have big-endian support in the release binaries. so need to use FVPs to test those libraries.

Similar comment to #553: should we move the expansion of library variants inside the add_library_variants_for_cpu function, like we do for exceptions/rtti,instead of adding more calls to it? That will probably make this patch a bit more complicated, as we'll need to pass both the QEMU and FVP parameters into the call and select the right one for each variant, but in the longer term we'll want big-endian and strict-align variants for (almost) every library variant, so it should simplify things in the end.
