2019-11-06introduce -fcallgraph-info optionEric Botcazou1-0/+6
This was first submitted many years ago https://gcc.gnu.org/ml/gcc-patches/2010-10/msg02468.html The command line option -fcallgraph-info is added and makes the compiler generate another output file (xxx.ci) for each compilation unit (or LTO partitoin), which is a valid VCG file (you can launch your favorite VCG viewer on it unmodified) and contains the "final" callgraph of the unit. "final" is a bit of a misnomer as this is actually the callgraph at RTL expansion time, but since most high-level optimizations are done at the Tree level and RTL doesn't usually fiddle with calls, it's final in almost all cases. Moreover, the nodes can be decorated with additional info: -fcallgraph-info=su adds stack usage info and -fcallgraph-info=da dynamic allocation info. for gcc/ChangeLog From Eric Botcazou <ebotcazou@adacore.com>, Alexandre Oliva <oliva@adacore.com> * common.opt (-fcallgraph-info[=]): New option. * doc/invoke.texi (Developer options): Document it. * opts.c (common_handle_option): Handle it. * builtins.c (expand_builtin_alloca): Record allocation if -fcallgraph-info=da. * calls.c (expand_call): If -fcallgraph-info, record the call.

2019-10-29[AArch64] Add support for the SVE PCSRichard Sandiford1-2/+2
The AAPCS64 specifies that if a function takes arguments in SVE registers or returns them in SVE registers, it must preserve all of Z8-Z23 and all of P4-P11. (Normal functions only preserve the low 64 bits of Z8-Z15 and clobber all of the predicate registers.) This variation is known informally as the "SVE PCS" and functions that use it are known informally as "SVE functions". The SVE PCS is mutually interoperable with functions that follow the standard AAPCS64 rules and those that use the aarch64_vector_pcs attribute. (Note that it's an error to use the attribute for SVE functions.) One complication -- although it's not really that complicated -- is that SVE registers need to be saved at a VL-dependent offset while other registers need to be saved at a constant offset. The easiest way of handling this seemed to be to group the SVE registers together below the hard frame pointer. In common cases, the frame pointer is then usually an easy-to-compute VL multiple above the stack pointer and a constant amount below the incoming stack pointer. A bigger complication is that, because the base AAPCS64 specifies that only the low 64 bits of V8-V15 are preserved by calls, the associated DWARF frame registers are also treated as 64 bits by the unwinder. The 64 bits must also have the same layout as they would for a base AAPCS64 function, otherwise unwinding won't work correctly. (This is actually a problem for the existing aarch64_vector_pcs support too, but I'll fix that separately.) This falls out naturally for little-endian targets but not for big-endian targets. The easiest way of meeting the requirement for them was to use ST1D and LD1D to save and restore Z8-Z15, which also has the nice property of storing the 64 bits at the start of the slot. However, using ST1D and LD1D requires a spare predicate register, and since all of P0-P7 are either argument registers or call-preserved, we may need to spill P4 in order to save the vector registers, even if P4 wouldn't need to be saved otherwise. Since Z16-Z23 are fully clobbered by base AAPCS64 functions, we don't need to emit frame information for them at all. This avoids having to decide whether the registers should be treated as having 64 bits (as for Z8-Z15), 128 bits (for Advanced SIMD) or the full SVE width. There are two ways of dealing with stack-clash protection when saving SVE registers: (1) If the area between the hard frame pointer and the incoming stack pointer is allocated via a store with writeback (callee_adjust != 0), the SVE save area is allocated separately and becomes the "initial" allocation as far as stack-clash protection goes. In this case the store with writeback acts as a probe at the hard frame pointer position. (2) If the area between the hard frame pointer and the incoming stack pointer is allocated via aarch64_allocate_and_probe_stack_space, the SVE save area is added to this initial allocation, so that the SP ends up pointing at the SVE register saves. It's then necessary to use a temporary base register to save the non-SVE registers. Setting up this temporary register requires a single instruction only and so should be more efficient than doing two allocations and probes. When SVE registers need to be saved, saving them below the frame pointer makes it harder to rely on the LR save as a stack probe, since the LR register's offset won't usually be a compile-time constant. The patch copes with that by using the lowest SVE register save as a stack probe too, and thus prevents the save from being shrink-wrapped if stack clash protection is enabled. The changelog describes the low-level details. 2019-10-29 Richard Sandiford <richard.sandiford@arm.com> gcc/ * calls.c (pass_by_reference): Leave the target to decide whether POLY_INT_CST-sized arguments should be passed by value or reference, rather than forcing them to be passed by reference.

2019-08-20Add a pass_by_reference flag to function_arg_infoRichard Sandiford1-0/+3
This patch adds a flag that tells targets whether an argument has been converted to pass-by-reference form. This replaces assign_parm_data_one::passed_pointer in function.c. The flag is set automatically for places that call apply_pass_by_reference_rules. Places that apply pass-by-reference manually need to set it themselves.

They all go through apply_pass_by_reference_rules.) 2019-08-20 Richard Sandiford <richard.sandiford@arm.com> gcc/ * calls.h (function_arg_info): Add a pass_by_reference field, defaulting to false. * calls.c (apply_pass_by_reference_rules): Set pass_by_reference when applying pass-by-reference semantics.

2019-08-20Add a apply_pass_by_reference_rules helperRichard Sandiford1-0/+16
This patch adds a helper routine that applies pass-by-reference semantics to an existing function_arg_info. The c6x part means that c6x_function_arg and c6x_function_arg_advance see the same "named" value as pass_by_reference did, rather than pass_by_reference seeing "true" and the others seeing "false". This doesn't matter because the c6x port doesn't care about namedness. The rs6000.c patch removes an assignment to "type", but the only later code to use it was the patched promote_mode line. (The reason for patching these places despite the above is that often target code gets used as a basis for new targets or changes to existing ones.) 2019-08-20 Richard Sandiford <richard.sandiford@arm.com> gcc/ * calls.h (apply_pass_by_reference_rules): Declare. * calls.c (apply_pass_by_reference_rules): New function. * config/c6x/c6x.c (c6x_call_saved_register_used): Use it. * config/rs6000/rs6000-call.c (rs6000_parm_needs_stack): Likewise. * config/s390/s390.c (s390_call_saved_register_used): Likewise. * function.c (assign_parm_find_data_types): Likewise. * var-tracking.c (prepare_call_arguments): Likewise.

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.

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.

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.

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.

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.
