Subject: glsl: Completely initialize value member in ir_constant constructor.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=30a086552827b82738421ff2d562e3c8c1da2735;p=mesa.git

glsl: Completely initialize value member in ir_constant constructor.

The
ir_constant::ir_constant(const struct glsl_type *type, exec_list *value_list)
did not completely initialize the entire value member.

Fixes piglit glsl-fs-sampler-numbering-2 valgrind uninitialized value
error in softpipe and llvmpipe.
