[PATCH 2/2] Split out -Wframe-larger-than warning from WARN_CLFAGS

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

 



Introduce STRICT_FRAME_LIMIT_CFLAGS that will be used for
the library code and RELAXED_FRAME_LIMIT_CFLAGS for daemon code
and the test code.

Raising the limit for tests allows building them with clang
with optimizations disabled.
