.. envvar:: INTEL_SHADER_BIN_DUMP_PATH
if set, determines the directory to which the compiled shaders will be
dumped. They will be dumped as ``sha1_of_assembly.bin``, where the sha1
values will be the same as can be found in the :envvar:`INTEL_DEBUG`
output, and can be used for :envvar:`INTEL_SHADER_ASM_READ_PATH` input.

Unlike the text form of shader dumping, :envvar:`INTEL_DEBUG`
does not affect on the list of shaders to dump. All generated shaders
are always dumped if :envvar:`INTEL_SHADER_BIN_DUMP_PATH` variable is
set.
