This would be awesome, but can you tell me what is the point in
switching
between 2 bad compilers at the build time?
And just what is supposed to be bad about them?
Clang is too young and unstable, full of bugs,
Name a few.
Even when we were using a pre-release snapshot of clang 3.5, we ran
into only 1 thing that actually turned out to be a compiler bug (and
that's fixed in the 3.5 release). Doesn't sound very unstable or full
of bugs especially if we consider the number of "Internal Compiler
Errors" we typically get after a major gcc update.
There's a couple of projects that rely on gcc extensions (sometimes
even on particular gcc bugs) causing build failures with any other
compiler - but that's typically easy to fix, and if not, export CC=gcc
export CXX=g++ is perfectly fine.
the gcc4.9 that we
have in cooker
is worse then vanilla ,
How so? I'm using mostly clang these days, but I'm probably still one
of the heaviest gcc 4.9-2014.08 users here (esp. because that's the
compiler we use to build Android with at work) and haven't run into
any serious issues with it.
