From 8a3a81478dcc592518069125a6ad271fe5511b95 Mon Sep 17 00:00:00 2001 From: Max Filippov Date: Sun, 21 Jun 2020 22:26:50 -0700 Subject: target/xtensa: drop gen_io_end call Since commit ba3e7926691e ("icount: clean up cpu_can_io at the entry to the block") it has been unnecessary for target code to call gen_io_end() after an IO instruction in icount mode; it is sufficient to call gen_io_start() before it and to force the end of the TB. Remaining call in xtensa target translator is for the opcodes that may change IRQ state. All of them end current TB, so gen_io_end is not needed. Drop gen_io_end call from the xtensa target translator.
