Subject: Determine assembly flavor at a single place.
X-Git-Tag: v3_9_90~63^2~2
X-Git-Url: http://info.iut-bm.univ-fcomte.fr/pub/gitweb/simgrid.git/commitdiff_plain/a5700748e9db05e5e91e50c92cb3054f71b9b515?hp=ab4dd058e59625e67e29b3328b8aad99f6f90c27

Determine assembly flavor at a single place.

In smx_context_raw.c, check if variable exists *and* has a nonnull value
(and not only if it's defined).
