We already have a load_cpu_field_low32() to load the low half of a 64-bit CPU struct field to a TCGv_i32; however we haven't yet needed the store equivalent. We'll want that in the next patch, so implement it. Signed-off-by: Peter Maydell <peter.maydell@linaro.org> --- target/arm/tcg/translate-a32.h | 7 +++++++ 1 file changed, 7 insertions(+)
