2020-05-28Add support for __builtin_bswap128Eric Botcazou1-0/+2
This patch introduces a new builtin named __builtin_bswap128 on targets where TImode is supported, i.e. 64-bit targets only in practice. The implementation simply reuses the existing double word path in optab, so no routine is added to libgcc (which means that you get two calls to _bswapdi2 in the worst case). gcc/ChangeLog: * builtin-types.def (BT_UINT128): New primitive type. (BT_FN_UINT128_UINT128): New function type. * builtins.def (BUILT_IN_BSWAP128): New GCC builtin. * doc/extend.texi (__builtin_bswap128): Document it. * builtins.c (expand_builtin): Deal with BUILT_IN_BSWAP128.

2020-02-13sccvn: Handle bitfields in vn_reference_lookup_3 [PR93582]Jakub Jelinek1-0/+64
The following patch is first step towards fixing PR93582. vn_reference_lookup_3 right now punts on anything that isn't byte aligned, so to be able to lookup a constant bitfield store, one needs to use the exact same COMPONENT_REF, otherwise it isn't found. This patch lifts up that that restriction if the bits to be loaded are covered by a single store of a constant (keeps the restriction so far for the multiple store case, can tweak that incrementally, but I think for bisection etc. it is worth to do it one step at a time). 2020-02-13 Jakub Jelinek <jakub@redhat.com> PR tree-optimization/93582 * fold-const.h (shift_bytes_in_array_left, shift_bytes_in_array_right): Declare. * fold-const.c (shift_bytes_in_array_left, shift_bytes_in_array_right): New function, moved from gimple-ssa-store-merging.c, no longer static. * gimple-ssa-store-merging.c (shift_bytes_in_array): Move to gimple-ssa-store-merging.c and rename to shift_bytes_in_array_left.

2019-12-07PR c++/91678 - wrong error with decltype and location wrapper.Marek Polacek1-0/+1
Compiling this testcase results in a bogus "invalid cast" error; this occurs since the introduction of location wrappers in finish_id_expression. Here we are parsing the decltype expression via cp_parser_decltype_expr which can lead to calling various fold_* and c-family routines. They use non_lvalue_loc, but that won't create a NON_LVALUE_EXPR wrapper around a location wrapper. So before the location wrappers addition cp_parser_decltype_expr would return NON_LVALUE_EXPR <c>. Now it returns VIEW_CONVERT_EXPR<float *>(c), but the STRIP_ANY_LOCATION_WRAPPER immediately following it strips the location wrapper, and suddenly we don't know whether we have an lvalue anymore. And that's sad because then decltype produces the wrong type, causing nonsense errors. * fold-const.c (maybe_lvalue_p): Handle VIEW_CONVERT_EXPR. * g++.dg/cpp0x/decltype73.C: New test.

2019-12-04Fix VIEW_CONVERT_EXPRs for VECTOR_BOOLEAN_TYPE_PsRichard Sandiford1-69/+94
In r278410 I added code to handle VIEW_CONVERT_EXPRs between variable-length vectors. This included support for decoding a VECTOR_BOOLEAN_TYPE_P with subbyte elements. However, it turns out that we were already mishandling such bool vectors for fixed-length vectors: we treated each element as a stand-alone byte instead of putting multiple elements into the same byte. I think in principle this could have been an issue for AVX512 as well. This patch adds encoding support for boolean vectors and reuses a version of the new decode support for fixed-length vectors. 2019-12-04 Richard Sandiford <richard.sandiford@arm.com> gcc/ * fold-const.c (native_encode_vector_part): Handle VECTOR_BOOLEAN_TYPE_Ps that have subbyte precision.

2019-11-18Handle VIEW_CONVERT_EXPR for variable-length vectorsRichard Sandiford1-9/+130
This patch handles VIEW_CONVERT_EXPRs of variable-length VECTOR_CSTs by adding tree-level versions of native_decode_vector_rtx and simplify_const_vector_subreg. It uses the same code for fixed-length vectors, both to get more coverage and because operating directly on the compressed encoding should be more efficient for longer vectors with a regular pattern. The structure and comments are very similar between the tree and rtx routines. 2019-11-18 Richard Sandiford <richard.sandiford@arm.com> gcc/ * fold-const.c (native_encode_vector): Turn into a wrapper function, splitting the main code out into...

2019-08-13Use checking forms of DECL_FUNCTION_CODE (PR 91421)Richard Sandiford1-1/+2
We were shoe-horning all built-in enumerations (including frontend and target-specific ones) into a field of type built_in_function. This was accessed as either an lvalue or an rvalue using DECL_FUNCTION_CODE. The obvious danger with this (as was noted by several ??? comments) is that the ranges have nothing to do with each other, and targets can easily have more built-in functions than generic code. But my patch to make the field bigger was the straw that finally made the problem visible. This patch therefore: - replaces the field with a plain unsigned int - turns DECL_FUNCTION_CODE into an rvalue-only accessor that checks that the function really is BUILT_IN_NORMAL - adds corresponding DECL_MD_FUNCTION_CODE and DECL_FE_FUNCTION_CODE accessors for BUILT_IN_MD and BUILT_IN_FRONTEND respectively - adds DECL_UNCHECKED_FUNCTION_CODE for places that need to access the underlying field (should be low-level code only) - adds new helpers for setting the built-in class and function code - makes DECL_BUILT_IN_CLASS an rvalue-only accessor too, since all assignments should go through the new helpers 2019-08-13 Richard Sandiford <richard.sandiford@arm.com> gcc/ PR middle-end/91421 * tree-core.h (function_decl::function_code): Change type to unsigned int. * tree.h (DECL_FUNCTION_CODE): Rename old definition to...

2018-12-19C++: more location wrapper nodes (PR c++/43064, PR c++/43486)David Malcolm1-4/+13
This is v6 of the patch, as posted to: https://gcc.gnu.org/ml/gcc-patches/2018-12/msg01331.html The C++ frontend gained various location wrapper nodes in r256448 (GCC 8). That patch: https://gcc.gnu.org/ml/gcc-patches/2018-01/msg00799.html added wrapper nodes around all nodes with !CAN_HAVE_LOCATION_P for: * arguments at callsites, and for * typeid, alignof, sizeof, and offsetof. This is a followup to that patch, adding many more location wrappers to the C++ frontend. It adds location wrappers for nodes with !CAN_HAVE_LOCATION_P to: * all literal nodes (in cp_parser_primary_expression) * all id-expression nodes (in finish_id_expression), except within a decltype. * all mem-initializer nodes within a mem-initializer-list (in cp_parser_mem_initializer) However, the patch also adds some suppressions: regions in the parser for which wrapper nodes will not be created: * within a template-parameter-list or template-argument-list (in cp_parser_template_parameter_list and cp_parser_template_argument_list respectively), to avoid encoding the spelling location of the nodes in types. For example, "array<10>" and "array<10>" are the same type, despite the fact that the two different "10" tokens are spelled in different locations in the source. * within a gnu-style attribute (none of are handlers are set up to cope with location wrappers yet) * within various OpenMP clauses The patch enables various improvements to locations for bad initializations, for -Wchar-subscripts, and enables various other improvements in the followup patch. For example, given the followup buggy mem-initializer: class X { X() : bad(42), good(42) { } void* bad; int good; }; previously, our diagnostic was on the final close parenthesis of the mem-initializer-list, leaving it unclear where the problem is: t.cc: In constructor 'X::X()': t.cc:3:16: error: invalid conversion from 'int' to 'void*' [-fpermissive] 3 | good(42) | ^ | | | int whereas with the patch we highlight which expression is bogus: t.cc: In constructor 'X::X()': t.cc:2:13: error: invalid conversion from 'int' to 'void*' [-fpermissive] 2 | X() : bad(42), | ^~ | | | int Similarly, the diagnostic for this bogus initialization: i.cc:1:44: error: initializer-string for array of chars is too long [-fpermissive] 1 | char test[3][4] = { "ok", "too long", "ok" }; | ^ is improved by the patch so that it indicates which string is too long: i.cc:1:27: error: initializer-string for array of chars is too long [-fpermissive] 1 | char test[3][4] = { "ok", "too long", "ok" }; | ^~~~~~~~~~ gcc/c-family/ChangeLog: PR c++/43064 PR c++/43486 * c-common.c (unsafe_conversion_p): Fold any location wrapper.
