[Mesa-dev] [PATCH 0/6] glsl_to_tgsi: Further improvement of lifetime tracking for register merge

[Gert Wollny]

Dear all,

this set of patches fixes some memory leak in mesa/st/tests, enhances the
debugging output used in the temporary register lifetime estimation, and
further improves the lifetime tracking by handling if-else path in more detail
and by also tracking the registers used for indirect access. The latter is a
feat that is currently not needed, but will become relevant when Mareks patches
land, that allow any 1D register as a TGSI address operand, and when that
request merge_registers want to make use of this feature.

My tests showed no changes in piglit "quick" and "shader".

many thanks for any comments,
Gert
