[Mesa-dev] glsl es question: invalid pragma debug argument

Hello,

I found a GLSL ES test that provides an invalid argument to #pragma
debug() such as:

    #pragma debug (1.23)

And it expects a compilation error. Mesa doesn't complain about it,
just ignore the whole thing. The allowed keywords are 'on' and 'off'
for that pragma.

- From GLSL ES 3.00 spec, chapter 3.4 (Preprocessor), page 12:

       "#pragma allows implementation dependent compiler control.
       Tokens following #pragma are not subject to preprocessor macro
       expansion. If an implementation does not recognize the tokens
       following #pragma, then it will ignore that pragma. [...] The
       debug pragma
          #pragma debug(on)
          #pragma debug(off)
       can be used to enable compiling and annotating a shader with
       debug information, so that it can be used with a debugger. It
       can only be used outside function definitions. By default, debug
       is turned off.
       The scope as well as the effect of the optimize and debug
       pragmas is implementation-dependent except that their use must
       not generate an error."

So, from the spec, I understand that Mesa is doing the right thing but
I would like to have a confirmation because it is a valid pragma but
with wrong argument.

Thanks,

Sam
