To: gcc-bugs
I have found this bug when playing a bit with the vector_size attribute. To
reproduce just compile the attached program with
gcc -march=pentium4 runsimd.c
Result:
runsimd.c:1: internal compiler error: in round_up, at fold-const.c:11606
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.
