Hi, I was investigating an ICE (in our yet to be upstreamed back-end which has native support for float16), on "gcc.dg/torture/float16-complex.c" when compiled with lto:
./gcc/build/gcc/xgcc -B./gcc/build/gcc/ ./gcc/gcc/testsuite/gcc.dg/torture/float16-complex.c \ -O2 -flto -fno-use-linker-plugin -flto-partition=none -lm -o ./float16-complex.exe I narrowed it down to the fact that lto-lang does not support _FloatNx types, the function "lto_type_for_mode" (in gcc/lto/lto-lang.c) and "c_common_type_for_mode" (in gcc/c-family/c-common.c) are exactly the same except that "lto_type_for_mode" does not support _FloatNx. Is this intentional or an oversight? Cheers, Paul
