https://gcc.gnu.org/g:5b648c42c11d243c7a93492c46dfd20b174294a8 commit r17-3378-g5b648c42c11d243c7a93492c46dfd20b174294a8 Author: Jeff Law <[email protected]> Date: Tue Aug 18 09:21:26 2026 -0600 [RISC-V] Testsuite adjustments after recent threading change The recent changes to the threader are causing us to pick up threads that were previously missed/ignored. Those threads change the structure of the loops and result in additional rounding mode changes (outside the loop). I'm not 100% convinced the change is profitable for these cases, but regardless this turns off the threader so that the tests continue to check for the basic behavior of tracking rounding modes. Verified this fixes the recent regressions on riscv32-elf and riscv64-elf.
