From 554dbcce77cc7eb38b786c77eee87a5f391b090b Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Thu, 3 Jun 2010 09:31:46 -0700 Subject: [PATCH] ir_to_mesa: Move the classes into the file now that we don't have the burg. At 1kloc, it doesn't look like I'll want to split the ir_to_mesa file up even once it's feature-complete. Move definitions closer to usage, and prevent rebuilding the world when changing the definitions. --- glsl_parser_extras.h | 2 + ir_to_mesa.cpp | 120 +++++++++++++++++++++++++++++++++++++--- ir_to_mesa.h | 152 --------------------------------------------------- 3 files changed, 115 insertions(+), 159 deletions(-) delete mode 100644 ir_to_mesa.h diff --git a/glsl_parser_extras.h b/glsl_parser_extras.h index 87de908..cfe02e3 100644 --- a/glsl_parser_extras.h +++ b/glsl_parser_extras.h @@ -134,4 +134,6 @@ extern bool _mesa_glsl_process_extension(const char *name, YYLTYPE *name_locp, extern const char * _mesa_glsl_shader_target_name(enum _mesa_glsl_parser_targets target); +void do_ir_to_mesa(exec_list *instructions); + #endif /* GLSL_PARSER_EXTRAS_H */ diff --git a/ir_to_mesa.cpp b/ir_to_mesa.cpp index 8a5b2a6..7a1f206 100644 --- a/ir_to_mesa.cpp +++ b/ir_to_mesa.cpp @@ -28,16 +28,9 @@ * printing the result */ -/* Quiet compiler warnings due to monoburg not marking functions defined - * in the header as inline. - */ -#define g_new -#define g_error - #include #include "ir.h" #include "ir_visitor.h" -#include "ir_to_mesa.h" #include "ir_print_visitor.h" #include "ir_expression_flattening.h" #include "glsl_types.h" @@ -47,6 +40,119 @@ extern "C" { #include "shader/prog_print.h" } +/** + * This struct is a corresponding struct to Mesa prog_src_register, with + * wider fields. + */ +typedef struct ir_to_mesa_src_reg { + int file; /**< PROGRAM_* from Mesa */ + int index; /**< temporary index, VERT_ATTRIB_*, FRAG_ATTRIB_*, etc. */ + int swizzle; /**< SWIZZLE_XYZWONEZERO swizzles from Mesa. */ + int negate; /**< NEGATE_XYZW mask from mesa */ + bool reladdr; /**< Register index should be offset by address reg. */ +} ir_to_mesa_src_reg; + +typedef struct ir_to_mesa_dst_reg { + int file; /**< PROGRAM_* from Mesa */ + int index; /**< temporary index, VERT_ATTRIB_*, FRAG_ATTRIB_*, etc. */ + int writemask; /**< Bitfield of WRITEMASK_[XYZW] */ +} ir_to_mesa_dst_reg; + +extern ir_to_mesa_src_reg ir_to_mesa_undef; + +class ir_to_mesa_instruction : public exec_node { +public: + enum prog_opcode op; + ir_to_mesa_dst_reg dst_reg; + ir_to_mesa_src_reg src_reg[3]; + /** Pointer to the ir source this tree came from for debugging */ + ir_instruction *ir; +}; + +class temp_entry : public exec_node { +public: + temp_entry(ir_variable *var, int file, int index) + : file(file), index(index), var(var) + { + /* empty */ + } + + int file; + int index; + ir_variable *var; /* variable that maps to this, if any */ +}; + +class ir_to_mesa_visitor : public ir_visitor { +public: + ir_to_mesa_visitor(); + + int next_temp; + int next_constant; + + ir_to_mesa_src_reg get_temp(int size); + + ir_to_mesa_src_reg get_temp_for_var(ir_variable *var); + + struct ir_to_mesa_src_reg src_reg_for_float(float val); + + /** + * \name Visit methods + * + * As typical for the visitor pattern, there must be one \c visit method for + * each concrete subclass of \c ir_instruction.
