2019-08-20Use function_arg_info for TARGET_MUST_PASS_IN_STACKRichard Sandiford1-16/+16
The hook is passed the promoted mode instead of the original type mode. The expr.h reference in the documentation is no longer correct, but pointing to calls.h or calls.c doesn't help much either. I just left this as-is since it's not related to the point of the series. After previous changes, most places already pass arg.mode and arg.type. Only i386 and mcore needed to construct a new one out of nothing. rs6000 needs to construct one slightly earlier than before. 2019-08-20 Richard Sandiford <richard.sandiford@arm.com> gcc/ * target.def (must_pass_in_stack): Take a function_arg_info instead of a mode and a type. * doc/tm.texi: Regenerate. * calls.h (must_pass_in_stack_var_size): Take a function_arg_info instead of a mode and a type.

2019-08-20Use function_arg_info for TARGET_FUNCTION_ARG_ADVANCERichard Sandiford1-4/+9
There seems to be a bit of confusion around this one. Almost all callers pass the same arguments as TARGET_FUNCTION_ARG, meaning that the mode is the promoted mode rather than the type mode. But the calls.c handling for normal typed arguments instead passes the unpromoted TYPE_MODE (despite passing the promoted mode to TARGET_FUNCTION_ARG). I've kept this behaviour with a ??? comment. (The calls.c handling of libgcc functions does pass the promoted mode though, as does the function.c handling of incoming arguments.) Also, a couple of the arm callers don't seem to be using the hook correctly. Again I kept the current choices and added a ??? comment. 2019-08-20 Richard Sandiford <richard.sandiford@arm.com> gcc/ * target.def (function_arg_advance): Take a function_arg_info instead of a mode, type and named flag. * doc/tm.texi: Regenerate. * targhooks.h (default_function_arg_advance): Take a function_arg_info instead of a mode, type and named flag. * targhooks.c (default_function_arg_advance): Likewise. * calls.c (initialize_argument_information): Update call to targetm.calls.function_arg_advance.

2019-08-20Use function_arg_info for TARGET_ARG_PARTIAL_BYTESRichard Sandiford1-6/+6
This patch adds the function_arg_info class and uses it for TARGET_ARG_PARTIAL_BYTES. The hook is passed the promoted mode instead of the original type mode. The arguments aren't mentioned in the documentation, which is why the target.def change is so small. The patch changes "true" to "arg.named" in: gcc_assert (!epiphany_pass_by_reference (cum, mode, type, /* named */ true)); but epiphany_pass_by_reference doesn't care about the named flag. 2019-08-20 Richard Sandiford <richard.sandiford@arm.com> gcc/ * target.def (arg_partial_bytes): Take a function_arg_info instead of a mode, type and named flag. * doc/tm.texi: Regenerate. * target.h (function_arg_info): Declare. * calls.h (function_arg_info): New class. * targhooks.h (hook_int_CUMULATIVE_ARGS_mode_tree_bool_0): Delete.

2019-08-13Protect some checks of DECL_FUNCTION_CODERichard Sandiford1-6/+4
This patch protects various uses of DECL_FUNCTION_CODE that didn't obviously check for BUILT_IN_NORMAL first (either directly or in callers). They could therefore trigger for functions that either aren't built-ins or are a different kind of built-in. Also, the patch removes a redundant GIMPLE_CALL check from optimize_stdarg_builtin, since it gave the impression that the stmt was less well checked than it actually is. 2019-08-13 Richard Sandiford <richard.sandiford@arm.com> gcc/ PR middle-end/91421 * attribs.c (decl_attributes): Check the DECL_BUILT_IN_CLASS before the DECL_FUNCTION_CODE. * calls.c (maybe_warn_alloc_args_overflow): Use fndecl_built_in_p to check for a BUILT_IN_ALLOCA call. * ipa-cp.c (ipa_get_indirect_edge_target_1): Likewise for BUILT_IN_UNREACHABLE.

2018-08-20Add support for grouping of related diagnostics (PR other/84889)David Malcolm1-0/+1
We often emit logically-related groups of diagnostics. A relatively simple case is this: if (warning_at (body_loc, OPT_Wmultistatement_macros, "macro expands to multiple statements")) inform (guard_loc, "some parts of macro expansion are not guarded by " "this %qs clause", guard_tinfo_to_string (keyword)); where the "note" diagnostic issued by the "inform" call is guarded by the -Wmultistatement_macros warning. More complicated examples can be seen in the C++ frontend, where e.g. print_z_candidates can lead to numerous "note" diagnostics being emitted. I'm looking at various ways to improve how we handle such related diagnostics, but, prior to this patch, there was no explicit relationship between these diagnostics: the diagnostics subsystem had no way of "knowing" that these were related. This patch introduces a simple way to group the diagnostics: an auto_diagnostic_group class: all diagnostics emitted within the lifetime of an auto_diagnostic_group instance are logically grouped. Hence in the above example, the two diagnostics can be grouped by simply adding an auto_diagnostic_group instance: auto_diagnostic_group d; if (warning_at (body_loc, OPT_Wmultistatement_macros, "macro expands to multiple statements")) inform (guard_loc, "some parts of macro expansion are not guarded by " "this %qs clause", guard_tinfo_to_string (keyword)); Some more awkard cases are of the form: if (some_condition && warning_at (...) && more_conditions) inform (...); which thus need restructuring to: if (some_condition) { auto_diagnostic_group d; warning_at (...); if (more_conditions) inform (...); } so that the lifetime of the auto_diagnostic_group groups the warning_at and the inform call. Nesting is handled by simply tracking a nesting depth within the diagnostic_context.: all diagnostics are treated as grouped until the final auto_diagnostic_group is popped. diagnostic.c uses this internally, so that all diagnostics are part of a group - those that are "by themselves" are treated as being part of a group with one element. The diagnostic_context gains optional callbacks for displaying the start of a group (when the first diagnostic is emitted within it), and the end of a group (for when the group was non-empty); these callbacks are unused by default, but a test plugin demonstrates them (and verifies that the machinery is working). As noted above, I'm looking at various ways to use the grouping to improve how we output the diagnostics. FWIW, I experimented with a more involved implementation, of the form: diagnostic_group d; if (d.warning_at (body_loc, OPT_Wmultistatement_macros, "macro expands to multiple statements")) d.inform (guard_loc, "some parts of macro expansion are not guarded by " "this %qs clause", guard_tinfo_to_string (keyword)); which had the advantage of allowing auto-detection of the places where groups were needed (by converting ::warning_at's return type to bool), but it was a much more invasive patch, especially when dealing with the places in the C++ frontend that can emit numerous notes after an error or warning (and thus having to pass the group around) Hence I went with this simpler approach. gcc/c-family/ChangeLog: PR other/84889 * c-attribs.c (common_handle_aligned_attribute): Add auto_diagnostic_group instance. * c-indentation.c (warn_for_misleading_indentation): Likewise. * c-opts.c (c_common_post_options): Likewise. * c-warn.c (warn_logical_not_parentheses): Likewise.

This patch makes load_register_parameters cope with polynomial sizes. The requirement here is that any register parameters with non-constant sizes must either have a specific mode (e.g. a variable-length vector mode) or must be represented with a PARALLEL. This is in practice already a requirement for parameters passed in vector registers, since the default behaviour of splitting parameters into words doesn't make sense for them. 2018-01-03 Richard Sandiford <richard.sandiford@linaro.org> Alan Hayward <alan.hayward@arm.com> David Sherwood <david.sherwood@arm.com> gcc/ * calls.c (load_register_parameters): Cope with polynomial mode sizes.

PUSH_ROUNDING is difficult to convert to a hook since there is still a lot of conditional code based on it. It isn't clear that a direct conversion with checks for null hooks is the right thing to do.

2017-12-21poly_int: REG_ARGS_SIZERichard Sandiford1-2/+2
This patch adds new utility functions for manipulating REG_ARGS_SIZE notes and allows the notes to carry polynomial as well as constant sizes. The code was inconsistent about whether INT_MIN or HOST_WIDE_INT_MIN should be used to represent an unknown size. The patch uses HOST_WIDE_INT_MIN throughout. 2017-12-21 Richard Sandiford <richard.sandiford@linaro.org> Alan Hayward <alan.hayward@arm.com> David Sherwood <david.sherwood@arm.com> gcc/ * rtl.h (get_args_size, add_args_size_note): New functions.
