[PATCH 1/2] llvm: warn instead of assert on global inits

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Currently, sparse-llvm can't emit the needed code for
all initializers and when it's the case it stop abruptly
with an assert(0).

This is kinda useless.

Somehow fix this by issuing a warning instead and try to
continue gracefully.
