--- Comment #2 from ptomsich at gcc dot gnu.org --- Note that this ICE does not reproduce by compiling three-gpp-channel-model.cc on its own; that file is only the source location LTRANS attributes the crash to. Compiling it standalone is clean, with or without -flto (confirmed non-LTO, -flto -shared, and -flto with unresolved symbols ignored — all clean). Reproduction requires the full 753.ns3_r link at -Ofast -flto -mcpu=ampere1 on aarch64. The failure needs whole-program (cross-TU) inlining to separate the fcmp from the branch, so reversed_comparison_code can no longer trace the MODE_CC comparison and returns UNKNOWN.
