Hi Wilco, This has probably been reported elsewhere already but I can't find such a report, so sorry for possible duplicate, but this patch is causing ICEs on aarch64 FAIL: gcc.target/aarch64/sve/reduc_1.c -march=armv8.2-a+sve (internal compiler error) FAIL: gcc.target/aarch64/sve/reduc_5.c -march=armv8.2-a+sve (internal compiler error) and also many scan-assembler regressions: http://people.linaro.org/~christophe.lyon/cross-validation/gcc/trunk/260951/report-build-info.html Can you check? Thanks Christophe
