--- Comment #5 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Richard Biener <[email protected]>: https://gcc.gnu.org/g:9baaca2adeca178edf8c0816ef328dba1cf270bc commit r17-2981-g9baaca2adeca178edf8c0816ef328dba1cf270bc Author: Richard Biener <[email protected]> Date: Wed Aug 5 10:31:47 2026 +0200 tree-optimization/126650 - get_inner_reference_aff and bitfields get_inner_reference_aff tries to compensate for bit precision offsets and sizes by rounding down and up, but fails to do this correctly. The following makes it more obviously correct by rounding positions and computing the rounded size based on those. PR tree-optimization/126650 * tree-affine.cc (get_inner_reference_aff): Fixup rounding of size. * gcc.dg/torture/pr126650.c: New testcase.
