# Compiler support for SVE is still pretty rough: GCC 10+11 produce incorrect code for fixed-width vectors,
# while Clang 12 produces memory-corrupting heisenbugs unless we enable the address sanitizer.
# In the RNG tests, GCC 10+11 produce an internal compiler error.
# The memory corruption seems to only happen with qemu-user, not with qemu-system.
# Once the compilers and QEMU have improved, this job should be cleaned up to match the others.
# SVE support is still unreliable in GCC 11 (incorrect code for fixed-width vectors, internal compiler errors).

# The RISC-V vector extension is still experimental and needs special compiler flags.
# Once they are officially released, this job should be cleaned up to match the others.
# RISC-V vector extension are currently not supported by GCC.
# Also, the image is built without the libomp package which is not yet available on Ubuntu.
