Hi,
this series moves decision about throwing window overflow exception to
translation phase and stops code generation early when privilege, window
overflow or coprocessor exception is thrown.
LTP test suite with this series applied runs 6% faster.
Max Filippov (2):
target-xtensa: record available window in TB flags
target-xtensa: don't generate dead code
target-xtensa/cpu.h | 12 +
target-xtensa/helper.h | 2 +-
target-xtensa/op_helper.c | 29 +-
target-xtensa/translate.c | 661 ++++++++++++++++++++++++----------------------
