* glsl2: move constructor into .cpp file to work around compiler bugBrian Paul2010-08-241-0/+12
| | | | | | | Fixes fd.o bug 29770 The refcount==0 assertion only failed on some systems. One example being 32-bit Linux with gcc 4.4.4.
* glsl: Add assert to check variable_entry referenced_count after construction.Vinson Lee2010-08-241-0/+1
| | | | | | | | | | A variable_entry after construction should have its referenced_count member set to 0. However, occassionally this isn't the case and entry->referenced_count has been observed to be a garbage value. This leads to crashes of several tests in the Piglit test suite. This patch adds an assert to check that a variable_entry instance has its referenced_count member initialized to 0 after construction.
