This patch adds a wrapper around smallest_mode_for_size for cases in which the mode class is MODE_INT. Unlike (int_)mode_for_size, smallest_mode_for_size always returns a mode of the specified class, asserting if no such mode exists. smallest_int_mode_for_size therefore returns a scalar_int_mode rather than an opt_scalar_int_mode. 2017-08-30 Richard Sandiford <richard.sandiford@linaro.org> Alan Hayward <alan.hayward@arm.com> David Sherwood <david.sherwood@arm.com> gcc/ * machmode.h (smallest_mode_for_size): Fix formatting.

This patch adds a POD class for scalar integers, as an instance of a new pod_mode template.

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. The as_a <scalar_int_mode> goes away in a later patch. 2017-08-30 Richard Sandiford <richard.sandiford@linaro.org> Alan Hayward <alan.hayward@arm.com> David Sherwood <david.sherwood@arm.com> gcc/ * config/powerpcspe/powerpcspe.h (rs6000_pmode): Change type from machine_mode to scalar_int_mode. * config/powerpcspe/powerpcspe.c (rs6000_pmode): Likewise.

This patch adds a macro that extracts the TYPE_MODE and forcibly converts it to a scalar_float_mode. The forcible conversion includes a gcc_checking_assert that the mode is a SCALAR_FLOAT_MODE_P. This becomes important as more static type checking is added by later patches. It has the additional benefit of bypassing the VECTOR_TYPE_P (...) ? vector_type_mode (...) : ... condition in TYPE_MODE; in release builds the new macro is a simple field access. 2017-08-30 Richard Sandiford <richard.sandiford@linaro.org> Alan Hayward <alan.hayward@arm.com> David Sherwood <david.sherwood@arm.com> gcc/ * tree.h (SCALAR_FLOAT_TYPE_MODE): New macro. * builtins.c (expand_builtin_signbit): Use it instead of TYPE_MODE. * fold-const.c (fold_convert_const_real_from_fixed): Likewise.

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.

Later patches will add wrapper types for specific classes of mode. E.g. SImode will be a scalar_int_mode, SFmode will be a scalar_float_mode, etc. This patch prepares for that change by adding an E_ prefix to the mode enum values. It also adds #defines that map the unprefixed names to the prefixed names; e.g: #define QImode E_QImode Later patches will change this to use things like scalar_int_mode where appropriate. The patch continues to use enum values to initialise static data. This isn't necessary for correctness, but it cuts down on the amount of load-time initialisation and shouldn't have any downsides. The patch also changes things like: cmp_mode == DImode ? DFmode : DImode to: cmp_mode == DImode ? E_DFmode : E_DImode This is because DImode and DFmode will eventually be different classes, so the original ?: wouldn't be well-formed. 2017-08-30 Richard Sandiford <richard.sandiford@linaro.org> Alan Hayward <alan.hayward@arm.com> David Sherwood <david.sherwood@arm.com> gcc/ * genmodes.c (mode_size_inline): Add an E_ prefix to mode names.

* semantics.c (finish_id_expression): Remove special dependent case. Avoid some later pieces when dependent. (finish_qualified_id_expr): Do normal BASELINK handling in a template. Always build a SCOPE_REF for a destructor BIT_NOT_EXPR. (parsing_default_capturing_generic_lambda_in_template): Remove. * parser.c (cp_parser_postfix_dot_deref_expression): Always give an error for types that will never be complete. * mangle.c (write_expression): Add sanity check. * tree.c (build_qualified_name): Add sanity check. (cp_walk_subtrees): Walk into the class context of a BASELINK. * lambda.c (add_capture): Improve diagnostic for generic lambda capture failure. * call.c (build_new_method_call_1): Print the right constructor name.

re PR target/82015 (PowerPC should check if 2nd argument to __builtin_unpackv1ti and similar functions is 0 or 1) [gcc] 2017-08-29 Michael Meissner <meissner@linux.vnet.ibm.com> PR target/82015 * config/rs6000/rs6000.c (rs6000_expand_binop_builtin): Insure that the second argument of the built-in functions to unpack 128-bit scalar types to 64-bit values is 0 or 1.
