<pre>Unfortunately some developers still don't seem to read the specifications and
write code that should not work.
For example if no #version is set in shaders, according to spec glsl version
1.10 is assumed. I would like a way to override that behavior.
There are already two variables related to that:
force_glsl_extensions_warn
MESA_GLSL_VERSION_OVERRIDE
but as far as I am aware the first doesn't help with syntax changes like arrays
as out or inout parameters and the second does apparently not influence what
the compiler will assume when no #version is set.
An example of a shader that can not be compiled with
force_glsl_extensions_warn=true MESA_GLSL_VERSION_OVERRIDE=130 would be this
one:
void a(inout vec4 b[1]) {}
Some time ago this was on the mailing list, but rejected because for several
reason that was the wrong place and way to do it:
