* config/c6x/c6x.md (collapse-ndfa, no-comb-vect): New automata_options. (d1, l1, s1, m1, d2, l2, s2, m2): Changed to define_query_cpu_unit. (l1w, s1w, l2w, s2w): Define in the main automaton. (fps1, fpl1, adddps1, adddpl1, fps2, fpl2, adddps2, adddpl2): New units. * config/c6x/c6x.c (c6x_sched_insn_info): Add unit_mask member. (c6x_unit_names): Add the new units. (c6x_unit_codes): New static array. (UNIT_QID_D1, UNIT_QID_L1, UNIT_QID_S1, UNIT_QID_M1, UNIT_QID_FPS1, UNIT_QID_FPL1, UNIT_QID_ADDDPS1, UNIT_QID_ADDDPL1, UNIT_QID_SIDE_OFFSET): New macros. (RESERVATION_S2): Adjust value. (c6x_option_override): Compute c6x_unit_codes. (assign_reservations): Take the unit_mask of the last instruction into account. Detect floating point reservations by looking for the new units. Don't assign reservations if the field is already nonzero. (struct c6x_sched_context): Add member prev_cycle_state_ctx. (init_sched_state): Initialize it. (c6x_clear_sched_context): Free it. (insn_set_clock): Clear reservation. (prev_cycle_state): New static variable. (c6x_init_sched_context): Save it. (c6x_sched_init): Allocate space for it and clear it. (c6x_sched_dfa_pre_cycle_insn): New static function. (c6x_dfa_new_cycle): Save state at the start of a new cycle. (c6x_variable_issue): Only record units in the unit_mask that were not set at the start of the cycle. (c6x_variable_issue): Compute and store the unit_mask from the current state. (reorg_split_calls): Ensure the new information remains correct. (TARGET_SCHED_DFA_NEW_CYCLE, TARGET_SCHED_CLEAR_SCHED_CONTEXT, TARGET_SCHED_DFA_PRE_CYCLE_INSN): Define. * config/c6x/c6x.h (CPU_UNITS_QUERY): Define. * config/c6x/c6x-sched.md.in (fp4_ls_N__CROSS_, adddp_ls_N__CROSS_): Add special reservations. * config/c6x/c6x-sched.md: Regenerate.

This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the files whose names start with COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs/ for how to report bugs usefully.
