2020-11-17Add MODE_OPAQUEAaron Sawdey1-0/+4
After discussion with Richard Sandiford on IRC, he suggested adding a new mode class MODE_OPAQUE to deal with the problems (PR 96791) we had been having with POImode/PXImode in powerpc target. This patch is the accumulation of changes I needed to make to add this and make it useable for the purposes of what power10 MMA needed. MODE_OPAQUE modes allow you to have modes for which you can just define loads and stores. By design, optimization does not expect to know how to do arithmetic or subregs on these modes. This allows us to have modes for multi-register vector operations where we don't want to open Pandora's Box and define general arithmetic operations. This patch will be followed by a target specific patch to change the powerpc power10 MMA builtins to use opaque modes, and will also let use use the vector pair loads/stores defined with that in the inline expansion of memcpy/memmove, allowing me to fix PR 96791. gcc/ChangeLog PR target/96791 * mode-classes.def: Add MODE_OPAQUE. * machmode.def: Add OPAQUE_MODE. * tree.def: Add OPAQUE_TYPE for types that will use MODE_OPAQUE. * doc/generic.texi: Document OPAQUE_TYPE. * doc/rtl.texi: Document MODE_OPAQUE. * machmode.h: Add OPAQUE_MODE_P(). * genmodes.c (complete_mode): Add MODE_OPAQUE.

2019-11-14Support vectorisation with mixed vector sizesRichard Sandiford1-0/+3
After previous patches, it's now possible to make the vectoriser support multiple vector sizes in the same vector region, using related_vector_mode to pick the right vector mode for a given element mode. No port yet takes advantage of this, but I have a follow-on patch for AArch64. This patch also seemed like a good opportunity to add some more dump messages: one to make it clear which vector size/mode was being used when analysis passed or failed, and another to say when we've decided to skip a redundant vector size/mode. 2019-11-14 Richard Sandiford <richard.sandiford@arm.com> gcc/ * machmode.h (opt_machine_mode::operator==): New function.

2019-11-14Replace mode_for_int_vector with related_int_vector_modeRichard Sandiford1-14/+1
mode_for_int_vector, like mode_for_vector, can sometimes return an integer mode or an unsupported vector mode. But no callers are interested in that case, and only want supported vector modes. This patch therefore replaces mode_for_int_vector with related_int_vector_mode, which gives the target a chance to pick its preferred vector mode for the given element mode and size. 2019-11-14 Richard Sandiford <richard.sandiford@arm.com> gcc/ * machmode.h (mode_for_int_vector): Delete.

2019-11-14Add a targetm.vectorize.related_mode hookRichard Sandiford1-0/+2
This patch is the first of a series that tries to remove two assumptions: (1) that all vectors involved in vectorisation must be the same size (2) that there is only one vector mode for a given element mode and number of elements Relaxing (1) helps with targets that support multiple vector sizes or that require the number of elements to stay the same. E.g. if we're vectorising code that operates on narrow and wide elements, and the narrow elements use 64-bit vectors, then on AArch64 it would normally be better to use 128-bit vectors rather than pairs of 64-bit vectors for the wide elements. Relaxing (2) makes it possible for -msve-vector-bits=128 to produce fixed-length code for SVE. It also allows unpacked/half-size SVE vectors to work with -msve-vector-bits=256. The patch adds a new hook that targets can use to control how we move from one vector mode to another. The hook takes a starting vector mode, a new element mode, and (optionally) a new number of elements. The flexibility needed for (1) comes in when the number of elements isn't specified. All callers in this patch specify the number of elements, but a later vectoriser patch doesn't. 2019-11-14 Richard Sandiford <richard.sandiford@arm.com> gcc/ * target.def (related_mode): New hook. * doc/tm.texi.in (TARGET_VECTORIZE_RELATED_MODE): New hook. * doc/tm.texi: Regenerate. * targhooks.h (default_vectorize_related_mode): Declare. * targhooks.c (default_vectorize_related_mode): New function. * machmode.h (related_vector_mode): Declare. * stor-layout.c (related_vector_mode): New function. * expmed.c (extract_bit_field_1): Use it instead of mode_for_vector. * optabs-query.c (qimode_for_vec_perm): Likewise. * tree-vect-stmts.c (get_group_load_store_type): Likewise.

2019-10-07Use CONSTEXPR in machmode.hRichard Sandiford1-25/+62
This patch adds CONSTEXPR to constructors and operators in machmode.h, excluding the controversial constexpr-resistant "() {}" constructors, which would become "= default" if we required C++11. Some of the other routines could potentially be constexpr too, but that can be done on an as-needed basis. 2019-10-07 Richard Sandiford <richard.sandiford@arm.com> gcc/ * machmode.h (opt_mode): Mark constructors with CONSTEXPR.

2019-08-13[AArch64] Improve SVE constant movesRichard Sandiford1-4/+5
If there's no SVE instruction to load a given constant directly, this patch instead tries to use an Advanced SIMD constant move and then duplicates the constant to fill an SVE vector. The main use of this is to support constants in which each byte is in { 0, 0xff }. Also, the patch prefers a simple integer move followed by a duplicate over a load from memory, like we already do for Advanced SIMD. This is a useful option to have and would be easy to turn off via a tuning parameter if necessary. The patch also extends the handling of wide LD1Rs to big endian, whereas previously we punted to a full LD1RQ. 2019-08-13 Richard Sandiford <richard.sandiford@arm.com> gcc/ * machmode.h (opt_mode::else_mode): New function.

This patch adds a new mode class to represent vectors of booleans.

2017-12-16poly_int: MACRO_MODERichard Sandiford1-0/+11
This patch uses a MACRO_MODE wrapper for the target macro invocations in targhooks.c and address.h, so that macros for non-AArch64 targets can continue to treat modes as fixed-size. It didn't seem worth converting the address macros to hooks since (a) they're heavily used, (b) they should be probably be replaced with a different interface rather than converted to hooks as-is, and most importantly (c) addresses.h already localises the problem. 2017-12-16 Richard Sandiford <richard.sandiford@linaro.org> Alan Hayward <alan.hayward@arm.com> David Sherwood <david.sherwood@arm.com> gcc/ * machmode.h (MACRO_MODE): New macro. * addresses.h (base_reg_class, ok_for_base_p_1): Use it. * targhooks.c (default_libcall_value, default_secondary_reload) (default_memory_move_cost, default_register_move_cost) (default_class_max_nregs): Likewise.

2017-11-01Add a fixed_size_mode classRichard Sandiford1-0/+33
This patch adds a fixed_size_mode machine_mode wrapper for modes that are known to have a fixed size. That applies to all current modes, but future patches will add support for variable-sized modes. The use of this class should be pretty restricted. One important use case is to hold the mode of static data, which can never be variable-sized with current file formats. Another is to hold the modes of registers involved in __builtin_apply and __builtin_result, since those interfaces don't cope well with variable-sized data. The class can also be useful when reinterpreting the contents of a fixed-length bit string as a different kind of value. 2017-11-01 Richard Sandiford <richard.sandiford@linaro.org> Alan Hayward <alan.hayward@arm.com> David Sherwood <david.sherwood@arm.com> gcc/ * machmode.h (fixed_size_mode): New class. * rtl.h (get_pool_mode): Return fixed_size_mode. * gengtype.c (main): Add fixed_size_mode. * target.def (get_raw_result_mode): Return a fixed_size_mode.

2017-09-05Make mode_for_size return an opt_modeRichard Sandiford1-5/+26
...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.

2017-08-30[39/77] Two changes to the get_best_mode interfaceRichard Sandiford1-7/+5
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.

2017-08-30[4/77] Add FOR_EACH iterators for modesRichard Sandiford1-0/+139
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.

2017-08-30[3/77] Allow machine modes to be classesRichard Sandiford1-45/+101
This patch makes various changes that allow modes like SImode to be classes rather than enums. Firstly, it adds inline functions for all mode size properties, with the macros being simple wrappers around them. This is necessary for the __builtin_constant_p trick to continue working effectively when the mode arguments are slightly more complex (but still foldable at compile time). These inline functions are trivial and heavily used. There's not much point keeping them out-of-line at -O0: if anything it would make debugging harder rather than easier, and it would also slow things down. The patch therefore marks them as "always_inline", if that's available. Later patches use this approach too. Using inline functions means that it's no longer possible to pass an int to GET_MODE_PRECISION etc. The Fortran and powerpcspe-c.c parts are needed to avoid instances of that. The patch continues to use enums for gencondmd.c, so that more mode comparisons are integer constant expressions when checking for always-true or always-false conditions. This is the only intended use of USE_ENUM_MODES. The patch also enforces the previous replacement of case statements by defining modes as: #define FOOmode ((void) 0, E_FOOmode) This adds no overhead but makes sure that new uses of "case FOOmode:" don't accidentally creep in when FOOmode has no specific class associated with it. 2017-08-30 Richard Sandiford <richard.sandiford@linaro.org> Alan Hayward <alan.hayward@arm.com> David Sherwood <david.sherwood@arm.com> gcc/ * genconditions.c (write_header): Add a "#define USE_ENUM_MODES". * genmodes.c (emit_insn_modes_h): Define FOOmode to E_FOOmode if USE_ENUM_MODES is defined and to ((void) 0, E_FOOmode) otherwise. * machmode.h (mode_size): Move earlier in file.

2017-07-02Reorganise machmode.h headersRichard Sandiford1-3/+0
This patch splits the auto-generated inline functions out of insn-modes.h and puts them in a new header file, insn-modes-inline.h. It also makes coretypes.h include these files directly, rather than indirectly via machmode.h. This in turn allows insn-modes-inline.h and machmode.h to come later in the include list, after wide-int.h. This is useful for later patches. insn-modes.h itself still needs to come first, since it provides configuration information like MAX_BITSIZE_MODE_ANY_INT, which is used to control the size of a wide_int. The patch also makes the generator files include machmode.h via coretypes.h. Previously they did it by more indirect means. Finally, the patch makes wide-int-print.h available via coretypes.h too. There didn't seem to be any reason to force only the print routines to be included directly, and it would be painful to extend that approach to the SVE patches.
