2023-02-27target/arm: move translate modules to tcg/Fabiano Rosas
Introduce the target/arm/tcg directory. Its purpose is to hold the TCG code that is selected by CONFIG_TCG.

2022-07-26target/arm: Add MO_128 entry to pred_esz_masks[]Peter Maydell
In commit 7390e0e9ab8475, we added support for SME loads and stores. Unlike SVE loads and stores, these include handling of 128-bit elements. The SME load/store functions call down into the existing sve_cont_ldst_elements() function, which uses the element size MO_* value as an index into the pred_esz_masks[] array. Because this code path now has to handle MO_128, we need to add an extra element to the array. This bug was spotted by Coverity because it meant we were reading off the end of the array. Resolves: Coverity CID 1490539, 1490541, 1490543, 1490544, 1490545, 1490546, 1490548, 1490549, 1490550, 1490551, 1490555, 1490557, 1490558, 1490560, 1490561, 1490563 Fixes: 7390e0e9ab8475 ("target/arm: Implement SME LD1, ST1") Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Reviewed-by: Richard Henderson <richard.henderson@linaro.org> Message-id: 20220718100144.3248052-1-peter.maydell@linaro.org
