2018-05-30Use poly_int tree accessorsRichard Sandiford1-3/+5
This patch generalises various places that used hwi tree accessors so that they can handle poly_ints instead. In many cases these changes are by inspection rather than because something had shown them to be necessary. I think the alias.c part is a minor bug fix: previously we used fits_uhwi_p for a signed HOST_WIDE_INT (which the caller does treat as signed rather than unsigned).

So far we've used integer modes for LD[234] and ST[234] arrays.

2018-01-03poly_int: TYPE_VECTOR_SUBPARTSRichard Sandiford1-3/+1
This patch changes TYPE_VECTOR_SUBPARTS to a poly_uint64. The value is encoded in the 10-bit precision field and was previously always stored as a simple log2 value. The challenge was to use this 10 bits to encode the number of elements in variable-length vectors, so that we didn't need to increase the size of the tree. In practice the number of vector elements should always have the form N + N * X (where X is the runtime value), and as for constant-length vectors, N must be a power of 2 (even though X itself might not be). The patch therefore uses the low 8 bits to encode log2(N) and bit 8 to select between constant-length and variable-length vectors. Targets without variable-length vectors continue to use the old scheme. A new valid_vector_subparts_p function tests whether a given number of elements can be encoded. This is false for the vector modes that represent an LD3 or ST3 vector triple (which we want to treat as arrays of vectors rather than single vectors). Most of the patch is mechanical; previous patches handled the changes that weren't entirely straightforward. 2018-01-03 Richard Sandiford <richard.sandiford@linaro.org> Alan Hayward <alan.hayward@arm.com> David Sherwood <david.sherwood@arm.com> gcc/ * tree.h (TYPE_VECTOR_SUBPARTS): Turn into a function and handle polynomial numbers of units.

This patch adds a tree representation for poly_ints. Unlike the rtx version, the coefficients are INTEGER_CSTs rather than plain integers, so that we can easily access them as poly_widest_ints and poly_offset_ints. The patch also adjusts some places that previously relied on "constant" meaning "INTEGER_CST". It also makes sure that the TYPE_SIZE agrees with the TYPE_SIZE_UNIT for vector booleans, given the existing: /* Several boolean vector elements may fit in a single unit. */ if (VECTOR_BOOLEAN_TYPE_P (type) && type->type_common.mode != BLKmode) TYPE_SIZE_UNIT (type) = size_int (GET_MODE_SIZE (type->type_common.mode)); else TYPE_SIZE_UNIT (type) = int_const_binop (MULT_EXPR, TYPE_SIZE_UNIT (innertype), size_int (nunits)); 2017-12-20 Richard Sandiford <richard.sandiford@linaro.org> Alan Hayward <alan.hayward@arm.com> David Sherwood <david.sherwood@arm.com> gcc/ * doc/generic.texi (POLY_INT_CST): Document. * tree.def (POLY_INT_CST): New tree code. * treestruct.def (TS_POLY_INT_CST): New tree layout. * tree-core.h (tree_poly_int_cst): New struct.

2017-10-10Require wi::to_wide for treesRichard Sandiford1-2/+4
The wide_int routines allow things like: wi::add (t, 1) to add 1 to an INTEGER_CST T in its native precision. But we also have: wi::to_offset (t) // Treat T as an offset_int wi::to_widest (t) // Treat T as a widest_int Recently we also gained: wi::to_wide (t, prec) // Treat T as a wide_int in preccision PREC This patch therefore requires: wi::to_wide (t) when operating on INTEGER_CSTs in their native precision. This is just as efficient, and makes it clearer that a deliberate choice is being made to treat the tree as a wide_int in its native precision. This also removes the inconsistency that a) INTEGER_CSTs in their native precision can be used without an accessor but must use wi:: functions instead of C++ operators b) the other forms need an explicit accessor but the result can be used with C++ operators. It also helps with SVE, where there's the additional possibility that the tree could be a runtime value. 2017-10-10 Richard Sandiford <richard.sandiford@linaro.org> gcc/ * wide-int.h (wide_int_ref_storage): Make host_dependent_precision a template parameter.

2017-09-05Make mode_for_size return an opt_modeRichard Sandiford1-31/+21
...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.

2017-09-05Make more use of int_mode_for_sizeRichard Sandiford1-4/+7
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.

2017-08-18Add warn_if_not_aligned attributeH.J. Lu1-0/+66
Add warn_if_not_aligned attribute as well as command line options: -Wif-not-aligned and -Wpacked-not-aligned. __attribute__((warn_if_not_aligned(N))) causes compiler to issue a warning if the field in a struct or union is not aligned to N: typedef unsigned long long __u64 __attribute__((aligned(4),warn_if_not_aligned(8))); struct foo { int i1; int i2; __u64 x; }; __u64 is aligned to 4 bytes. But inside struct foo, __u64 should be aligned at 8 bytes. It is used to define struct foo in such a way that struct foo has the same layout and x has the same alignment when __u64 is aligned at either 4 or 8 bytes. Since struct foo is normally aligned to 4 bytes, a warning will be issued: warning: alignment 4 of 'struct foo' is less than 8 Align struct foo to 8 bytes: struct foo { int i1; int i2; __u64 x; } __attribute__((aligned(8))); silences the warning. It also warns the field with misaligned offset: struct foo { int i1; int i2; int i3; __u64 x; } __attribute__((aligned(8))); warning: 'x' offset 12 in 'struct foo' isn't aligned to 8 This warning is controlled by -Wif-not-aligned and is enabled by default. When -Wpacked-not-aligned is used, the same warning is also issued for the field with explicitly specified alignment in a packed struct or union: struct __attribute__ ((aligned (8))) S8 { char a[8]; }; struct __attribute__ ((packed)) S { struct S8 s8; }; warning: alignment 1 of 'struct S' is less than 8 This warning is disabled by default and enabled by -Wall. gcc/ PR c/53037 * print-tree.c (print_node): Support DECL_WARN_IF_NOT_ALIGN and TYPE_WARN_IF_NOT_ALIGN. * stor-layout.c (do_type_align): Merge DECL_WARN_IF_NOT_ALIGN.

2016-11-25Set mode of decimal floats before calling layout_typeRichard Sandiford1-2/+5
Previously decimal floating-point types were created and laid out as binary floating-point types, then the caller changed the mode to a decimal mode later. The problem with that approach is that not all targets support an equivalent binary floating-point mode. When they didn't, we would give the type BLKmode and lay it out as a zero-sized type. This probably had no effect in practice. If a target doesn't support a binary mode then it's unlikely to support the decimal equivalent either. However, with the stricter mode checking added by later patches, we would assert if a scalar floating- point type didn't have a scalar floating-point mode. gcc/ 2016-11-16 Richard Sandiford <richard.sandiford@arm.com> Alan Hayward <alan.hayward@arm.com> David Sherwood <david.sherwood@arm.com> * stor-layout.c (layout_type): Allow the caller to set the mode of a float type.
