2014-12-17target-xtensa: record available window in TB flagsMax Filippov1-1/+1
Record last valid 4-register window pane number in TB flags so that a window overflow exception throw point is known at the translation time. Signed-off-by: Max Filippov <jcmvbkbc@gmail.com> Reviewed-by: Richard Henderson <rth@twiddle.net>
2014-05-28tcg: Invert the inclusion of helper.hRichard Henderson1-4/+0
Rather than include helper.h with N values of GEN_HELPER, include a secondary file that sets up the macros to include helper.h. This minimizes the files that must be rebuilt when changing the macros for file N. Reviewed-by: Alex Bennée <alex.bennee@linaro.org> Signed-off-by: Richard Henderson <rth@twiddle.net>

2012-10-28target-xtensa: rename helper flagsAurelien Jarno1-8/+8
