From e207b2e2c8dea99972e744c8fdfa0b9a9481ea5e Mon Sep 17 00:00:00 2001 From: =?utf8?q?Samuel=20Iglesias=20Gons=C3=A1lvez?= Date: Mon, 29 Jan 2018 13:46:28 +0100 Subject: [PATCH] glsl/linker: fix bug when checking precision qualifier MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit According to GLSL ES 3.2 spec, see table in 9.2.1 "Linked Shaders" section, the precision qualifier should match for uniform variables. This also applies to previous GLSL ES 3.x specs. This 'if' checks the condition for uniform variables, while for UBOs it is checked in link_interface_blocks.cpp. Fixes: b50b82b8a553 ("glsl/es31: precision qualifier doesn't need to match in shader interface block members") Signed-off-by: Samuel Iglesias Gonsálvez Reviewed-by: Tapani Pälli --- src/compiler/glsl/linker.cpp | 11 +++-------- 1 file changed, 3 insertions(+), 8 deletions(-) diff --git a/src/compiler/glsl/linker.cpp b/src/compiler/glsl/linker.cpp index d3d18c2..1444b68 100644 --- a/src/compiler/glsl/linker.cpp +++ b/src/compiler/glsl/linker.cpp @@ -1111,15 +1111,10 @@ cross_validate_globals(struct gl_shader_program *prog, return; } - /* Only in GLSL ES 3.10, the precision qualifier should not match - * between block members defined in matched block names within a - * shader interface. - * - * In GLSL ES 3.00 and ES 3.20, precision qualifier for each block - * member should match. + /* Check the precision qualifier matches for uniform variables on + * GLSL ES. */ - if (prog->IsES && (prog->data->Version != 310 || - !var->get_interface_type()) && + if (prog->IsES && !var->get_interface_type() && existing->data.precision != var->data.precision) { if ((existing->data.used && var->data.used) || prog->data->Version >= 300) { linker_error(prog, "declarations for %s `%s` have " -- 2.7.4
