2017-09-12Convert hard_regno_nregs to a functionRichard Sandiford1-6/+6
This patch converts hard_regno_nregs into an inline function, which in turn allows hard_regno_nregs to be used as the name of a targetm field.

2016-12-07GCC caches the whether a function is a leaf in crtl->is_leaf.Wilco Dijkstra1-5/+11
GCC caches the whether a function is a leaf in crtl->is_leaf. Using this in the backend is best as leaf_function_p may not work correctly (eg. while emitting prolog or epilog code). There are many reads of crtl->is_leaf before it is initialized. Many targets do in targetm.frame_pointer_required (eg. arm, aarch64, i386, mips, sparc), which is called before register allocation by ira_setup_eliminable_regset and sched_init. Additionally, SHRINK_WRAPPING_ENABLED calls targetm.have_simple_return, which evaluates the condition of the simple_return instruction. On ARM this results in a call to use_simple_return_p which requires crtl->is_leaf to be set correctly. To fix this, initialize crtl->is_leaf in ira_setup_eliminable_regset and early on in ira. A bootstrap did not find any uninitialized reads of crtl->is_leaf on Thumb-2. A follow-up patch will remove incorrect uses of leaf_function_p from the ARM backend. gcc/ * gcc/ira.c (ira_setup_eliminable_regset): Initialize crtl->is_leaf. (ira): Move initialization of crtl->is_leaf earlier. From-SVN: r243347
2016-11-30ira: Don't substitute into TRAP_IF insns (PR78610)Segher Boessenkool1-0/+5
In the testcase, IRA propagates a constant into a TRAP_IF insn, which then becomes an unconditional trap. Unconditional traps are control flow insns so doing this requires surgery on the cfg. We cannot do that here, so instead refuse to do the substitution.

2016-04-30ira.c validate_equiv_memAlan Modra1-30/+51
This function is used to validate REG_EQUIV notes generated by ira, and to validate potential insn combines performed by ira. The two conditions are not exactly the same, with reload being more restrictive. Separate them so more combines/moves can occur. For example, this sequence from cfgexpand.c:expand_gimple_cond callq _Z18update_bb_for_insnP15basic_block_def mov 0x10(%rbx),%rdi mov 0x0(%rip),%rbp # x_rtl+0x34 callq _Z9safe_as_aIP8rtx_insn7rtx_defET_PT0_ mov %r13,%rdx mov %rbp,%rsi mov %rax,%rdi callq _Z18create_basic_blockP7rtx_defS0_P15basic_block_def becomes callq _Z18update_bb_for_insnP15basic_block_def mov 0x10(%rbx),%rdi callq _Z9safe_as_aIP8rtx_insn7rtx_defET_PT0_ mov 0x0(%rip),%rsi # x_rtl+0x34 mov %r13,%rdx mov %rax,%rdi callq _Z18create_basic_blockP7rtx_defS0_P15basic_block_def * ira.c (enum valid_equiv): New.

2016-04-30ira.c use DF infrastructure for combine_and_move_insnsAlan Modra1-109/+86
This patch actually improves generated code, because REG_DEAD notes used by the old insn scan are not always present. On x86_64, see gcc/wide-int-print.o:print_hex for an example of a function that is smaller and uses one less callee saved reg. * ira.c (combine_and_move_insns): Rather than scanning insns, use DF infrastucture to find use and def insns. From-SVN: r235660
2016-04-30ira.c combine_and_move_insns, and ordering of functionsAlan Modra1-68/+16
Notes added by add_store_equivs are not used directly or indirectly by combine_and_move_insns. add_store_equivs can therefore run later without affecting the output of combine_and_move_insns, and thus add_store_equivs need not take into account potentially moved insns. Since not all potentially combined/moved insns are in fact combined or moved, this may allow add_store_equivs to add more REG_EQUIV notes. grow_reg_equivs isn't needed until the reload reg_equivs array is changed. ira.c (combine_and_move_insns): Move invariant conditions.. (ira.c): ..to here. Call combine_and_move_insns before add_store_equivs. Call grow_reg_equivs later. Allocate req_equiv later using max_reg_num() rather than global max_regno.
