From: "christophm30 at gmail dot com" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug rtl-optimization/100264] REE does not work on PARALLEL expressions with a single register SET child Date: Mon, 26 Apr 2021 11:45:58 +0000 [thread overview] Message-ID: <bug-100264-4-JqPwifEwle@http.gcc.gnu.org/bugzilla/> (raw) In-Reply-To: <bug-100264-4@http.gcc.gnu.org/bugzilla/> https://gcc.gnu.org/bugzilla/show_bug.cgi?id=100264 --- Comment #1 from Christoph M. <christophm30 at gmail dot com> --- A patch can be found here: https://gcc.gnu.org/pipermail/gcc-patches/2021-April/568680.html It does not show any regressions (target riscv*). The patch does not include a new test case to demonstrate it actually works, because I don't know a generic way to test it. At the moment I am testing indirectly using __atomic_compare_and_exchange () on riscv64 to emit the required store-conditional. However, the code required for that is not merged yet. Ideas on how to test this in a more generic way are very much appreciated.
