2017-12-20poly_int: C++ bitfield regionsRichard Sandiford1-5/+4
This patch changes C++ bitregion_start/end values from constants to poly_ints. Although it's unlikely that the size needs to be polynomial in practice, the offset could be with future language extensions. 2017-12-20 Richard Sandiford <richard.sandiford@linaro.org> Alan Hayward <alan.hayward@arm.com> David Sherwood <david.sherwood@arm.com> gcc/ * expmed.h (store_bit_field): Change bitregion_start and bitregion_end from unsigned HOST_WIDE_INT to poly_uint64. * expmed.c (adjust_bit_field_mem_for_reg, strict_volatile_bitfield_p) (store_bit_field_1, store_integral_bit_field, store_bit_field) (store_fixed_bit_field, store_split_bit_field): Likewise. * expr.c (store_constructor_field, store_field): Likewise.

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.

2017-09-15Turn TRULY_NOOP_TRUNCATION into a hookRichard Sandiford1-2/+2

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.

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.

Similar to the previous scalar_float_mode patch, but for modes that satisfy SCALAR_INT_MODE_P. There are very many uses of scalar integers, so this patch only makes a token change to the types of byte_mode, word_mode, ptr_mode and rs6000_pmode. The next patches in the series gradually replace more uses. The patch also removes and adds casts to some target-specific code due to the new types of SImode, DImode and Pmode.

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.
