2017-12-21poly_int: REG_ARGS_SIZERichard Sandiford1-1/+1
This patch adds new utility functions for manipulating REG_ARGS_SIZE notes and allows the notes to carry polynomial as well as constant sizes. The code was inconsistent about whether INT_MIN or HOST_WIDE_INT_MIN should be used to represent an unknown size. The patch uses HOST_WIDE_INT_MIN throughout. 2017-12-21 Richard Sandiford <richard.sandiford@linaro.org> Alan Hayward <alan.hayward@arm.com> David Sherwood <david.sherwood@arm.com> gcc/ * rtl.h (get_args_size, add_args_size_note): New functions. (find_args_size_adjust): Return a poly_int64 rather than a HOST_WIDE_INT. (fixup_args_size_notes): Likewise. Make the same change to the end_args_size parameter. * rtlanal.c (get_args_size, add_args_size_note): New functions. * builtins.c (expand_builtin_trap): Use add_args_size_note. * calls.c (emit_call_1): Likewise. * explow.c (adjust_stack_1): Likewise. * cfgcleanup.c (old_insns_match_p): Update use of find_args_size_adjust. * combine.c (distribute_notes): Track polynomial arg sizes. * dwarf2cfi.c (dw_trace_info): Change beg_true_args_size, end_true_args_size, beg_delay_args_size and end_delay_args_size from HOST_WIDE_INT to poly_int64. (add_cfi_args_size): Take the args_size as a poly_int64 rather than a HOST_WIDE_INT. (notice_args_size, notice_eh_throw, maybe_record_trace_start) (maybe_record_trace_start_abnormal, scan_trace, connect_traces): Track polynomial arg sizes. * emit-rtl.c (try_split): Use get_args_size. * recog.c (peep2_attempt): Likewise. * reload1.c (reload_as_needed): Likewise. * expr.c (find_args_size_adjust): Return the adjustment as a poly_int64 rather than a HOST_WIDE_INT. (fixup_args_size_notes): Change end_args_size from a HOST_WIDE_INT to a poly_int64 and change the return type in the same way. (emit_single_push_insn): Track polynomial arg sizes.

This patch makes get_object_alignment_2 track polynomial offsets and sizes.

2017-10-23Convert STARTING_FRAME_OFFSET to a hookRichard Sandiford1-1/+1
I took the documentation of the FRAME_GROWS_DOWNWARD behaviour from the version that was in most header files, since the one in the manual seemed less clear. The patch deliberately keeps FIRST_PARM_OFFSET(FNDECL) in microblaze_starting_frame_offset; this seems to be a port-local convention and takes advantage of the fact that FIRST_PARM_OFFSET doesn't read FNDECL. 2017-10-23 Richard Sandiford <richard.sandiford@linaro.org> gcc/ * target.def (starting_frame_offset): New hook. * doc/tm.texi (STARTING_FRAME_OFFSET): Remove in favor of...

2017-09-25Turn CONSTANT_ALIGNMENT into a hookRichard Sandiford1-2/+2
The definition: #define CONSTANT_ALIGNMENT(EXP, ALIGN) \ (TREE_CODE (EXP) == STRING_CST \ && (ALIGN) < BITS_PER_WORD ? BITS_PER_WORD : (ALIGN)) was very common, so the patch adds a canned definition for that, called constant_alignment_word_strings. Some ports had a variation that used a port-local FASTEST_ALIGNMENT instead of BITS_PER_WORD; the patch uses constant_alignment_word_strings if FASTEST_ALIGNMENT was always BITS_PER_WORD and a port-local hook function otherwise. 2017-09-25 Richard Sandiford <richard.sandiford@linaro.org> gcc/ * target.def (constant_alignment): New hook. * defaults.h (CONSTANT_ALIGNMENT): Delete. * doc/tm.texi.in (CONSTANT_ALIGNMENT): Replace with...

2017-09-05Make more use of int_mode_for_sizeRichard Sandiford1-6/+9
This patch converts more places that could use int_mode_for_size instead of mode_for_size. This is in preparation for an upcoming patch that makes mode_for_size itself return an opt_mode. require () seems like the right choice in expand_builtin_powi because we have got past the point of backing out. We go on to do: op1 = expand_expr (arg1, NULL_RTX, mode2, EXPAND_NORMAL); if (GET_MODE (op1) != mode2) op1 = convert_to_mode (mode2, op1, 0); which would be invalid for (and have failed for) BLKmode. In get_builtin_sync_mode and expand_ifn_atomic_compare_exchange, the possible bitsizes are {8, 16, 32, 64, 128}, all of which give target-independent integer modes (up to TImode). The comment above the call in get_builtin_sync_mode makes clear that an integer mode must be found. We can use require () in expand_builtin_atomic_clear and expand_builtin_atomic_test_and_set because there's always an integer mode for the boolean type. The same goes for the POINTER_SIZE request in layout_type. Similarly we can use require () in combine_instructions and gen_lowpart_common because there's always an integer mode for HOST_BITS_PER_WIDE_INT (DImode when BITS_PER_UNIT == 8), and HOST_BITS_PER_DOUBLE_INT (TImode). The calls in aarch64_function_value, arm_function_value, aapcs_allocate_return_reg and mips_function_value_1 are handling cases in which a big-endian target passes or returns values at the most significant end of a register. In each case the ABI constrains the size to a small amount and does not handle non-power-of-2 sizes wider than a word. The calls in c6x_expand_movmem, i386.c:emit_memset, lm32_block_move_inline, microblaze_block_move_straight and mips_block_move_straight are dealing with expansions of block memory operations using register-wise operations, and those registers must have non-BLK mode. The reason for using require () in ix86_expand_sse_cmp, mips_expand_ins_as_unaligned_store, spu.c:adjust_operand and spu_emit_branch_and_set is that we go on to emit non-call instructions that use registers of that mode, which wouldn't be valid for BLKmode. 2017-09-05 Richard Sandiford <richard.sandiford@linaro.org> gcc/ * builtins.c (expand_builtin_powi): Use int_mode_for_size.

2017-09-04PR82045: Avoid passing machine modes through "..."Richard Sandiford1-3/+3
PR82045 is about a bootstrap failure on sparc-sun-solaris2.11. The problem was that we were passing the new machine_mode wrapper classes through "..." to emit_library_call(_value), which then read them back as ints instead. The simplest fix seemed to be replace "..." with an array of rtx_mode_ts, then provide wrappers for the common cases. This bulks out rtl.h a bit, but it does make things a bit more typesafe. 2017-09-04 Richard Sandiford <richard.sandiford@linaro.org> gcc/ PR bootstrap/82045 * rtl.h (emit_library_call_value_1): Declare.

2017-08-30[9/77] Add SCALAR_FLOAT_TYPE_MODERichard Sandiford1-2/+3
This patch adds a macro that extracts the TYPE_MODE and forcibly converts it to a scalar_float_mode. The forcible conversion includes a gcc_checking_assert that the mode is a SCALAR_FLOAT_MODE_P. This becomes important as more static type checking is added by later patches. It has the additional benefit of bypassing the VECTOR_TYPE_P (...) ? vector_type_mode (...) : ... condition in TYPE_MODE; in release builds the new macro is a simple field access. 2017-08-30 Richard Sandiford <richard.sandiford@linaro.org> Alan Hayward <alan.hayward@arm.com> David Sherwood <david.sherwood@arm.com> gcc/ * tree.h (SCALAR_FLOAT_TYPE_MODE): New macro. * builtins.c (expand_builtin_signbit): Use it instead of TYPE_MODE. * fold-const.c (fold_convert_const_real_from_fixed): Likewise.

2017-08-30[4/77] Add FOR_EACH iterators for modesRichard Sandiford1-4/+2
The new iterators are: - FOR_EACH_MODE_IN_CLASS: iterate over all the modes in a mode class. - FOR_EACH_MODE_FROM: iterate over all the modes in a class, starting at a given mode. - FOR_EACH_WIDER_MODE: iterate over all the modes in a class, starting at the next widest mode after a given mode. - FOR_EACH_2XWIDER_MODE: same, but considering only modes that are two times wider than the previous mode. - FOR_EACH_MODE_UNTIL: iterate over all the modes in a class until a given mode is reached. - FOR_EACH_MODE: iterate over all the modes in a class between two given modes, inclusive of the first but not the second. These help with the stronger type checking added by later patches, since every new mode will be in the same class as the previous one. 2017-08-30 Richard Sandiford <richard.sandiford@linaro.org> Alan Hayward <alan.hayward@arm.com> David Sherwood <david.sherwood@arm.com> gcc/ * machmode.h (mode_traits): New structure.

2017-06-23Fix expand_builtin_atomic_fetch_op for pre-op (PR80902)Segher Boessenkool1-0/+6
__atomic_add_fetch adds a value to some memory, and returns the result. If there is no direct support for this, expand_builtin_atomic_fetch_op is asked to implement this as __atomic_fetch_add (which returns the original value of the mem), followed by the addition. Now, the __atomic_add_fetch could have been a tail call, but we shouldn't perform the __atomic_fetch_add as a tail call: following code would not be executed, and in fact thrown away because there is a barrier after tail calls. This fixes it. PR middle-end/80902 * builtins.c (expand_builtin_atomic_fetch_op): If emitting code after a call, force the call to not be a tail call. From-SVN: r249603
