Because they were pushed on the stack only when - * they were trivially colorable, any color chosen won't interfere - * with the registers to be popped later. - * - * The downside to most graph coloring is that real hardware often has - * limitations, like registers that need to be allocated to a node in - * pairs, or aligned on some boundary. This implementation follows - * the paper "Retargetable Graph-Coloring Register Allocation for - * Irregular Architectures" by Johan Runeson and Sven-Olof Nyström. - * - * In this system, there are register classes each containing various - * registers, and registers may interfere with other registers. For - * example, one might have a class of base registers, and a class of - * aligned register pairs that would each interfere with their pair of - * the base registers. Each node has a register class it needs to be - * assigned to. Define p(B) to be the size of register class B, and - * q(B,C) to be the number of registers in B that the worst choice - * register in C could conflict with. Then, this system replaces the - * basic graph coloring test of "fewer edges from this node than there - * are registers" with "For this node of class B, the sum of q(B,C) - * for each neighbor node of class C is less than pB". - * - * A nice feature of the pq test is that q(B,C) can be computed once - * up front and stored in a 2-dimensional array, so that the cost of - * coloring a node is constant with the number of registers. We do - * this during ra_set_finalize(). - */ - -#include - -#include "main/imports.h" -#include "main/macros.h" -#include "main/mtypes.h" -#include "register_allocate.h" - -#define NO_REG ~0 - -struct ra_reg { - GLboolean *conflicts; - unsigned int *conflict_list; - unsigned int conflict_list_size; - unsigned int num_conflicts; -}; - -struct ra_regs { - struct ra_reg *regs; - unsigned int count; - - struct ra_class **classes; - unsigned int class_count; -}; - -struct ra_class { - GLboolean *regs; - - /** - * p(B) in Runeson/Nyström paper. - * - * This is "how many regs are in the set." - */ - unsigned int p; - - /** - * q(B,C) (indexed by C, B is this register class) in - * Runeson/Nyström paper.

Because they were pushed on the stack only when + * they were trivially colorable, any color chosen won't interfere + * with the registers to be popped later. + * + * The downside to most graph coloring is that real hardware often has + * limitations, like registers that need to be allocated to a node in + * pairs, or aligned on some boundary. This implementation follows + * the paper "Retargetable Graph-Coloring Register Allocation for + * Irregular Architectures" by Johan Runeson and Sven-Olof Nyström. + * + * In this system, there are register classes each containing various + * registers, and registers may interfere with other registers. For + * example, one might have a class of base registers, and a class of + * aligned register pairs that would each interfere with their pair of + * the base registers. Each node has a register class it needs to be + * assigned to. Define p(B) to be the size of register class B, and + * q(B,C) to be the number of registers in B that the worst choice + * register in C could conflict with. Then, this system replaces the + * basic graph coloring test of "fewer edges from this node than there + * are registers" with "For this node of class B, the sum of q(B,C) + * for each neighbor node of class C is less than pB". + * + * A nice feature of the pq test is that q(B,C) can be computed once + * up front and stored in a 2-dimensional array, so that the cost of + * coloring a node is constant with the number of registers.
