# NOTE: Assertions have been autogenerated by utils/update_mir_test_checks.py UTC_ARGS: --version 5
# NOTE: This MIR test is required because the support for 64 bit memory ops is missing in X86 mode, Due to distinction between float/int types, support is expected in near future and there is this RFC in place https://discourse.llvm.org/t/rfc-globalisel-adding-fp-type-information-to-llt/83349. Once this support is introduced this test must be dropped and integrated into the LLVM IR tests.
