Now that the movcond TCG op is available, it's possible to replace shl and shr helpers by TCG code. The code generated by TCG is slightly longer than the code generated by GCC for the helper but is still worth it as this avoid all the consequences of using an helper: globals saved back to memory, no possible optimization, call overhead, etc. Signed-off-by: NAurelien Jarno <aurelien@aurel32.net> Signed-off-by: NPeter Maydell <peter.maydell@linaro.org>
