[Mesa-dev] [PATCH] nir: Mark the shader name during nir_sweep

[Neil Roberts]

Previously the name of the nir shader was being freed prematurely
during nir_sweep. Since 756613ed35d the name was later being used to
generate filenames for the optimiser debug output and these would end
up with garbage from the dangling pointer.
