2017-12-20Add a gen_int_shift_amount helper functionRichard Sandiford1-15/+21
This patch adds a helper routine that constructs rtxes for constant shift amounts, given the mode of the value being shifted. As well as helping with the SVE patches, this is one step towards allowing CONST_INTs to have a real mode. One long-standing problem has been to decide what the mode of a shift count should be for arbitrary rtxes (as opposed to those directly tied to a target pattern). Realistic choices would be the mode of the shifted elements, word_mode, QImode, a 64-bit mode, or the same mode as the shift optabs (in which case what should the mode be when the target doesn't have a pattern?) For now the patch picks a 64-bit mode, but with a ??? comment. 2017-12-20 Richard Sandiford <richard.sandiford@linaro.org> Alan Hayward <alan.hayward@arm.com> David Sherwood <david.sherwood@arm.com> gcc/ * emit-rtl.h (gen_int_shift_amount): Declare. * emit-rtl.c (gen_int_shift_amount): New function. * asan.c (asan_emit_stack_protection): Use gen_int_shift_amount instead of GEN_INT. * calls.c (shift_return_value): Likewise. * cse.c (fold_rtx): Likewise. * dse.c (find_shift_sequence): Likewise. * expmed.c (init_expmed_one_mode, store_bit_field_1, expand_shift_1) (expand_shift, expand_smod_pow2): Likewise. * lower-subreg.c (shift_cost): Likewise. * optabs.c (expand_superword_shift, expand_doubleword_mult) (expand_unop, expand_binop, shift_amt_for_vec_perm_mask) (expand_vec_perm_var): Likewise. * simplify-rtx.c (simplify_unary_operation_1): Likewise.

2017-11-09Base subreg rules on REGMODE_NATURAL_SIZE rather than UNITS_PER_WORDRichard Sandiford1-2/+3
Originally subregs operated at the word level and subreg offsets were measured in words. The offset units were later changed from words to bytes (SUBREG_WORD became SUBREG_BYTE), but the fundamental assumption that subregs should operate at the word level remained. Whether (subreg:M1 (reg:M2 R2) N) is well-formed depended on the way that M1 and M2 partitioned into words and whether the subword part of N represented a lowpart. However, some questions depended instead on the macro REGMODE_NATURAL_SIZE, which was introduced as part of the patch that moved from SUBREG_WORD to SUBREG_BYTE. It is used to decide whether setting (subreg:M1 (reg:M2 R2) N) clobbers all of R2 or just part of it (df_read_modify_subreg). Using words doesn't really make sense for modern vector architectures. Vector registers are usually bigger than a word and: (a) setting the scalar lowpart of them usually clobbers the rest of the register (contrary to the subreg rules, where only the containing words should be clobbered). (b) high words of vector registers are often not independently addressable, even though that's what the subreg rules expect. This patch therefore uses REGMODE_NATURAL_SIZE instead of UNITS_PER_WORD to determine the size of the independently addressable blocks in an inner register. This is needed for SVE because the number of words in a vector mode isn't known at compile time, so isn't a sensible basis for calculating the number of registers. The only existing port to define REGMODE_NATURAL_SIZE is 64-bit SPARC, where FP registers are 32 bits. (This is the opposite of the use case for SVE, since the natural division is smaller than a word.) I compiled the testsuite before and after the patch for sparc64-linux-gnu and the only test whose assembly changed was g++.dg/debug/pr65678.C, where the order of two independent stores was reversed and where a different register was picked for one pseudo. The new code was otherwise equivalent to the old code. 2017-11-09 Richard Sandiford <richard.sandiford@linaro.org> Alan Hayward <alan.hayward@arm.com> David Sherwood <david.sherwood@arm.com> gcc/ * doc/rtl.texi: Rewrite the subreg rules so that they partition the inner register into REGMODE_NATURAL_SIZE bytes rather than UNITS_PER_WORD bytes. * emit-rtl.c (validate_subreg): Divide subregs into blocks based on REGMODE_NATURAL_SIZE of the inner mode.

2017-11-01Widening optab cleanupRichard Sandiford1-2/+2
widening_optab_handler had the comment: /* ??? Why does find_widening_optab_handler_and_mode attempt to widen things that can't be widened? E.g. add_optab... */ if (op > LAST_CONV_OPTAB) return CODE_FOR_nothing; I think it comes from expand_binop using find_widening_optab_handler_and_mode for two things: to test whether a "normal" optab like add_optab is supported for a standard binary operation and to test whether a "convert" optab is supported for a widening operation like umul_widen_optab. In the former case from_mode and to_mode must be the same, in the latter from_mode must be narrower than to_mode. For the former case, find_widening_optab_handler_and_mode is only really testing the modes that are passed in. permit_non_widening must be true here. For the latter case, find_widening_optab_handler_and_mode should only really consider new from_modes that are wider than the original from_mode and narrower than the original to_mode. Logically permit_non_widening should be false, since widening optabs aren't supposed to take operands that are the same width as the destination. We get away with permit_non_widening being true because no target would/should define a widening .md pattern with matching modes. But really, it seems better for expand_binop to handle these two cases itself rather than pushing them down. With that change, find_widening_optab_handler_and_mode is only ever called with permit_non_widening set to false and is only ever called with a "proper" convert optab. We then no longer need widening_optab_handler, we can just use convert_optab_handler directly. The patch also passes the instruction code down to expand_binop_directly. This should be more efficient and removes an extra call to find_widening_optab_handler_and_mode. 2017-11-01 Richard Sandiford <richard.sandiford@linaro.org> Alan Hayward <alan.hayward@arm.com> David Sherwood <david.sherwood@arm.com> gcc/ * optabs-query.h (convert_optab_p): New function, split out from...

2017-11-01Allow vector CONSTsRichard Sandiford1-1/+9
This patch allows (const ...) wrappers to be used for rtx vector constants, as an alternative to const_vector. This is useful for SVE, where the number of elements isn't known until runtime. It could also be useful in future for fixed-length vectors, to reduce the amount of memory needed to represent simple constants with high element counts. However, one nice thing about keeping it restricted to variable-length vectors is that there is never any need to handle combinations of (const ...) and CONST_VECTOR. 2017-11-01 Richard Sandiford <richard.sandiford@linaro.org> Alan Hayward <alan.hayward@arm.com> David Sherwood <david.sherwood@arm.com> gcc/ * doc/rtl.texi (const): Update description of address constants.

2017-09-05Make mode_for_size return an opt_modeRichard Sandiford1-8/+3
...to make it consistent with int_mode_for_size etc. require () seems like the right choice in replace_reg_with_saved_mem because we use the chosen mode for saving and restoring registers, which cannot be done in BLKmode. Similarly require () seems like the right choice in calls related to secondary memory reloads (the ones in config/, and in get_secondary_mem) because the reload must always have a defined mode, which e.g. determines the size of the slot. We can use require () in simplify_subreg_concatn and assemble_integer because it isn't meaningful to create a subreg with BLKmode (for one thing, we couldn't tell then whether it was partial, paradoxical, etc.). make_fract_type and make_accum_type must find a mode because that's what distinguishes accumulator FIXED_POINT_TYPEs from fractional FIXED_POINT_TYPEs. 2017-09-05 Richard Sandiford <richard.sandiford@linaro.org> gcc/ * machmode.h (opt_machine_mode): New type.

2017-08-30Add a partial_subreg_p predicateRichard Sandiford1-2/+1
This patch adds a partial_subreg_p predicate to go alongside paradoxical_subreg_p. Like the paradoxical_subreg_p patch, this one replaces some tests that were based on GET_MODE_SIZE rather than GET_MODE_PRECISION. In each case the change should be a no-op or an improvement. The regcprop.c patch prevents some replacements of the 82-bit RFmode with the 80-bit XFmode on ia64. I don't understand the target details here particularly well, but from the way the modes are described in ia64-modes.def, it isn't valid to assume that an XFmode can carry an RFmode payload. A comparison of the testsuite assembly output for one target per CPU showed no other differences. Some of the places changed here are tracking the widest access mode found for a register. The series tries to standardise on: if (partial_subreg_p (widest_seen, new_mode)) widest_seen = new_mode; rather than: if (paradoxical_subreg_p (new_mode, widest_seen)) widest_seen = new_mode; Either would have been OK. 2017-08-30 Richard Sandiford <richard.sandiford@linaro.org> Alan Hayward <alan.hayward@arm.com> David Sherwood <david.sherwood@arm.com> gcc/ * rtl.h (partial_subreg_p): New function. * caller-save.c (save_call_clobbered_regs): Use it. * calls.c (expand_call): Likewise. * combine.c (combinable_i3pat): Likewise.

get_best_mode always returns a scalar_int_mode on success, so this patch makes that explicit in the type system. Also, the "largest_mode" argument is used simply to provide a maximum size, and in practice that size is always a compile-time constant, even when the concept of variable-sized modes is added later.

2017-08-22Make more use of paradoxical_subreg_pRichard Sandiford1-1/+1
This patch makes more use of the existing paradoxical_subreg_p predicate and also adds a version that operates on outer and inner modes. Some of the affected tests were based on GET_MODE_SIZE rather than GET_MODE_PRECISION and so the patch could change the result for modes that have the same size but different precisions. I think in each case the change should be a no-op or more correct, since a mode with precision N bits can't be expected to hold all of a mode with precision M>N bits. The patch changes the branch taken in simplify_subreg for modes with equal precision, but the new form matches the commentary more closely. Both branches should be equally good in that situation. 2017-08-22 Richard Sandiford <richard.sandiford@linaro.org> Alan Hayward <alan.hayward@arm.com> David Sherwood <david.sherwood@arm.com> gcc/ * rtl.h (paradoxical_subreg_p): Define inline, and add a version that takes the outer and inner modes. * doc/rtl.texi: Use paradoxical_subreg_p instead of a GET_MODE_SIZE comparison as the canonical test for a paradoxical subreg. * combine.c (simplify_set): Use paradoxical_subreg_p.

2016-11-18Use rtx_mode_t instead of std::make_pairRichard Sandiford1-2/+2
This change makes the code less sensitive to the exact type of the mode, i.e. it forces a conversion where necessary. This becomes important when wrappers like scalar_int_mode and scalar_mode can also be used instead of machine_mode. Using rtx_mode_t also abstracts away the representation. The fact that it's a std::pair rather than a custom class isn't important to users of the interface. gcc/ 2016-11-18 Richard Sandiford <richard.sandiford@arm.com> Alan Hayward <alan.hayward@arm.com> David Sherwood <david.sherwood@arm.com> * combine.c (try_combine): Use rtx_mode_t instead of std::make_pair. * dwarf2out.c (mem_loc_descriptor, loc_descriptor): Likewise.
