From 0cb1f25d86b0be00a84d1c4f3062cd64c4118b42 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Nicolai=20H=C3=A4hnle?= Date: Sun, 14 May 2017 19:58:53 +0200 Subject: [PATCH] glsl: do not lookup struct types by typename This changes the logic during the conversion of the declaration list struct S { ... } v; from AST to IR, but should not change the end result. When assigning the type of v, instead of looking `S' up in the symbol table, we read the type from the member variable of ast_struct_specifier. This change is necessary for the subsequent change to how anonymous types are handled. v2: remove a type override when redefining a structure; should be the same type in that case anyway Reviewed-by: Timothy Arceri --- src/compiler/glsl/ast.h | 1 + src/compiler/glsl/ast_to_hir.cpp | 14 ++++++++------ src/compiler/glsl/glsl_parser_extras.cpp | 1 + 3 files changed, 10 insertions(+), 6 deletions(-) diff --git a/src/compiler/glsl/ast.h b/src/compiler/glsl/ast.h index 9327e039793..3bf4b085800 100644 --- a/src/compiler/glsl/ast.h +++ b/src/compiler/glsl/ast.h @@ -844,6 +844,7 @@ public: /* List of ast_declarator_list * */ exec_list declarations; bool is_declaration; + const glsl_type *type; }; diff --git a/src/compiler/glsl/ast_to_hir.cpp b/src/compiler/glsl/ast_to_hir.cpp index e07e5f509b5..c67dfe5e88c 100644 --- a/src/compiler/glsl/ast_to_hir.cpp +++ b/src/compiler/glsl/ast_to_hir.cpp @@ -2359,7 +2359,10 @@ ast_type_specifier::glsl_type(const char **name, { const struct glsl_type *type; - type = state->symbols->get_type(this->type_name); + if (structure) + type = structure->type; + else + type = state->symbols->get_type(this->type_name); *name = this->type_name; YYLTYPE loc = this->get_location(); @@ -7504,13 +7507,12 @@ ast_struct_specifier::hir(exec_list *instructions, validate_identifier(this->name, loc, state); - const glsl_type *t = - glsl_type::get_record_instance(fields, decl_count, this->name); + type = glsl_type::get_record_instance(fields, decl_count, this->name); - if (!state->symbols->add_type(name, t)) { + if (!state->symbols->add_type(name, type)) { const glsl_type *match = state->symbols->get_type(name); /* allow struct matching for desktop GL - older UE4 does this */ - if (match != NULL && state->is_version(130, 0) && match->record_compare(t, false)) + if (match != NULL && state->is_version(130, 0) && match->record_compare(type, false)) _mesa_glsl_warning(& loc, state, "struct `%s' previously defined", name); else _mesa_glsl_error(& loc, state, "struct `%s' previously defined", name); @@ -7519,7 +7521,7 @@ ast_struct_specifier::hir(exec_list *instructions, const glsl_type *, state->num_user_structures + 1); if (s != NULL) { - s[state->num_user_structures] = t; + s[state->num_user_structures] = type; state->user_structures = s; state->num_user_structures++; } diff --git a/src/compiler/glsl/glsl_parser_extras.cpp b/src/compiler/glsl/glsl_parser_extras.cpp index 0f892b03a13..398bab55dd8 100644 --- a/src/compiler/glsl/glsl_parser_extras.cpp +++ b/src/compiler/glsl/glsl_parser_extras.cpp @@ -1690,6 +1690,7 @@ ast_struct_specifier::ast_struct_specifier(void *lin_ctx, const char *identifier this->declarations.push_degenerate_list_at_head(&declarator_list->link); is_declaration = true; layout = NULL; + type = NULL; } void ast_subroutine_list::print(void) const -- 2.30.2
