GCC Testing
When a new GCC is in the grimoire, especially if it breaks binary compatibility, any spells failing with it should get bugs filed http://bugs.sourcemage.org.
- Then the spell should either be patched (and the patch sent upstream) or made to use a "working" gcc.
How to make a spell using an older GCC
Example with gcc 3.4:
- make sure there is a spell for the older version - gcc34
- add 'depends gcc34' to DEPENDS
- add 'GCC_VERSION=3.4' to DETAILS
- add 'invoke_gcc' to PRE_BUILD if it uses a custom one
Note: The above used to say add 'invoke_gcc' to BUILD, but this was wrong as described in http://bugs.sourcemage.org/show_bug.cgi?id=10641
