10 years agoglsl: fix several use-after-free bugs
Brian Paul [Fri, 17 Oct 2014 19:31:53 +0000 (13:31 -0600)]
glsl: fix several use-after-free bugs

The get_variable_being_redeclared() function can free the 'var' argument.
Thereafter, we cannot assume that 'var' is a valid  pointer.  This patch
replaces 'var->name' with 'earlier->name' in two places and calls
is_gl_identifier(var->name) before 'var' might get freed.

This fixes several piglit GLSL crashes, including:
spec/glsl-1.50/execution/geometry/clip-distance-in-param
spec/glsl-1.50/execution/geometry/clip-distance-bulk-copy
spec/glsl-1.50/compiler/gs-redeclares-pervertex-out-before-global-redeclaration.geom

I'm not sure why these were not spotted sooner.

Until now, we've considered any BO to be possibly bound as a UBO or
TexBO, and flagged all that state to be reemitted.

Instead, remember what kinds of binding point this buffer has ever

i965/fs: Refactor the texture emission logic into a single function.

Before, we had 3 different emit functions for various different gen's,
as well as some ancilliary work that was the same across all gen's which
was either contained in functions or duplicated across the GLSL IR and
Mesa IR backends. Now, we have a single method, emit_texture(), that
takes all the information needed to make a texture instruction and
handles all the setup, and all we have to do to emit a texture
instruction while converting from GLSL IR, Mesa IR, or any new backend
is to extract the information emit_texture() needs and then call it.

v2: Significant rebasing (by Ken).

This happened to work before, but it would convert the output to a float
