2020-11-30[Ada] Implement inheritance for Default_Initial_Condition and address other gapsGary Dismukes15-268/+900
gcc/ada/ * einfo.ads (Is_Partial_DIC_Procedure): New function. (Partial_DIC_Procedure): New procedure. * einfo.adb (Is_Partial_DIC_Procedure): New function to return whether a subprogram is a partial Default_Initial_Condition procedure by checking the name (to avoid adding a new field). (DIC_Procedure): Add a test that excludes partial DIC procedures from being returned. (Partial_DIC_Procedure): New procedure to return the partial DIC procedure of a type, if it has one (otherwise returns Empty). (Set_DIC_Procedure): Remove check for duplicate DIC procedures. * exp_aggr.adb (Gen_Assign): Generate a call to the type's DIC procedure in the case where an array component is default initialized (due to an association with a box). (Build_Record_Aggr_Code): For an extension aggregate, generate a call to the ancestor type's DIC procedure (if any) when the ancestor part is a subtype mark. For a record component association that was specified with a box (tested for by checking the new flag Was_Default_Init_Box_Association), generate a call to the component type's DIC procedure (if it has one). * exp_ch4.adb (Expand_N_Allocator): When the allocated object is default initialized and the designated type has a DIC aspect, generate a call to the DIC procedure. * exp_util.ads (Build_DIC_Call): Change the formal Obj_Id to name Obj_Name, and change its type from Entity_Id to Node_Id (and update comment). (Build_DIC_Procedure_Body): Add formal Partial_DIC, remove formal For_Freeze, and update comment accordingly. (Build_DIC_Procedure_Declaration): Add formal Partial_DIC and update comment. * exp_util.adb (Build_DIC_Call): Revised to use its Obj_Name (formerly Obj_Id) formal directly rather than calling New_Occurrence_Of on it, to allow arbitrary names to be passed rather than being limited to Entity_Ids. (Build_DIC_Procedure_Body): Call Add_Parent_DICs to generate checks for DICs associated with any parent types, implementing the required "additive" semantics for DICs. When building a DIC procedure body for a partial view (when Partial_DIC is True), call Add_Own_DIC when the type has its own DIC. In the case of "full" DIC procedures, a call is generated to any partial DIC procedure of the type (unless the procedure has a null body), along with checks for any DICs inherited by the full view. (Build_DIC_Procedure_Declaration): Add handling for partial DIC procedures. For the suffix of a regular DIC procedure's name, use "DIC" (instead of "Default_Initial_Condition"), and for the suffix of a partial DIC procedure's name, use "Partial_DIC". (Add_DIC_Check): Add the DIC pragma to the list of seen pragmas (Pragmas_Seen). (Add_Inherited_Tagged_DIC): Remove the formals Par_Typ, Deriv_Typ, and Obj_Id, and add formal Expr, which denotes DIC's expression. Remove the call to Replace_References (which is now done in Add_Inherited_DICs). (Add_Inherited_DICs): New procedure to locate a DIC pragma associated with a parent type, replace its references appropriately (such as any current instance references), and add a check for the DIC. (Add_Own_DIC): Add an Obj_Id formal to allow caller to pass the _init formal of the generated DIC procedure. (Add_Parent_DICs): New procedure to traverse a type's parents, looking for DICs associated with those and calling Add_Inherited_DICs to apply the appropriate DIC checks. (Is_Verifiable_DIC_Pragma): Treat pragmas that have an Empty first argument the same as a pragma without any arguments (returning False for that case). * exp_ch3.adb (Init_One_Dimension): Generate calls to the component's DIC procedure when needed. (Possible_DIC_Call): New function nested in Init_One_Dimension to build a call to the array component type's DIC-checking function when appropriate. (Build_Array_Init_Proc): The presence of a DIC on the component type is an additional condition for generating an init proc for an array type. (Build_Init_Statements): When the record component's type has a DIC, and the component declaration does not have an initialization expression, generate a call to the component type's DIC procedure. (Expand_N_Object_Declaration): Modify the call to Build_DIC_Call to pass a new occurrence of the object's defining id rather than the id itself. (Freeze_Type): Only build a type's DIC procedure (if it has one) for types that are not interfaces. * exp_spark.adb (Expand_SPARK_N_Freeze_Type): Remove From_Freeze actual and add a ??? comment. (Expand_SPARK_N_Object_Declaration): Modify call to Build_DIC_Call to pass a new occurrence of the object id rather than the object id itself. * sem_aggr.adb (Resolve_Record_Aggregate): Declare local flag Is_Box_Init_By_Default and set it in cases where the component association has a box and the component is being initialized by default (as opposed to initialized by an initialization expression associated with the component's declaration). (Add_Association): If the association has a box for a component initialized by default, the flag Was_Default_Init_Box_Association is set on the new component association (for later testing during expansion). (Get_Value): Reset Is_Box_Init_By_Default to False. * sem_ch3.adb (Build_Assertion_Bodies_For_Type): Rearrange code to build DIC procedure bodies for a (noninterface) type that Has_Own_DIC (for partial type views) or Has_DIC (for full type views) as appropriate. * sem_ch13.adb (Analyze_Aspect_Specifications, Aspect_Default_Initial_Condition): Add an extra argument to the DIC pragma to denote the type associated with the pragma (for use in Build_DIC_Procedure_Body). * sem_prag.adb (Analyze_Pragma): Allow two arguments for pragma Default_Initial_Condition. If not already present, add an extra argument denoting the type that the pragma is associated with. * sem_util.adb (Propagate_DIC_Attributes): Retrieve any partial DIC procedure associated with the type and add it to the type's list of subprograms (Subprograms_For_Type). * sinfo.ads (Was_Default_Init_Box_Association): New flag on N_Component_Association nodes. Add subprograms to get and set flag, as well as updating the documentation. * sinfo.adb (Was_Default_Init_Box_Association): New function to retrieve the corresponding flag (Flag14). (Set_Was_Default_Init_Box_Association): New procedure to set the corresponding flag (Flag14).

2020-11-30[Obvious] arm: Fix test from failing on some targets [PR91816]Stam Markianos-Wright1-2/+3
This recently submitted test was found to fail on some Cortex-M targets. This was because codegen on these CPUs would emit a ldr instead of a movw/movt pair, resulting in an overall smaller test (i.e. the branch wasn't as far) and the behaviour being tested for not being triggered. This commit doubles the size of the test to account for this. gcc/testsuite/ChangeLog: * gcc.target/arm/pr91816.c: New test.
2020-11-30expansion: Improve double-word modulo by certain constant divisors [PR97459]Jakub Jelinek5-1/+337
As discussed in the PR, e.g. on x86_64 (both -m32 and -m64) there is no double-word modulo and so we expand it to a __{,u}mod[dt]i3 call. For certain constant divisors we can do better. E.g. consider 32-bit word-size, 0x100000000ULL % 3 == 1, so we can use partly the Hacker's delight modulo by summing digits approach and optimize unsigned long long foo (unsigned long long x) { return x % 3; } as unsigned long long foo (unsigned long long x) { unsigned int sum, carry; carry = __builtin_add_overflow ((unsigned int) x, (unsigned int) (x >> 32), &sum); sum += carry; return sum % 3; } Similarly, 0x10000000ULL % 5 == 1 (note, 1 << 28), so unsigned long long bar (unsigned long long x) { return x % 5; } as unsigned long long bar (unsigned long long x) { unsigned int sum = x & ((1 << 28) - 1); sum += (x >> 28) & ((1 << 28) - 1); sum += (x >> 56); return sum % 5; } etc. And we can do also signed modulo, long long baz (long long x) { return x % 5; } as long long baz (long long x) { unsigned int sum = x & ((1 << 28) - 1); sum += ((unsigned long long) x >> 28) & ((1 << 28) - 1); sum += ((unsigned long long) x >> 56); /* Sum adjustment for negative x. */ sum += (x >> 63) & 3; unsigned int rem = sum % 5; /* And finally adjust it to the right interval for negative values. */ return (int) (rem + ((x >> 63) & -4)); } 2020-11-30 Jakub Jelinek <jakub@redhat.com> PR rtl-optimization/97459 * internal-fn.h (expand_addsub_overflow): Declare. * internal-fn.c (expand_addsub_overflow): No longer static. * optabs.c (expand_doubleword_mod): New function.

2020-11-30Fix print_multilib_info when default arguments appear in the option list ↵Kito Cheng1-6/+17
with '!' This issue is found when we try to always define MULTILIB_DEFAULTS for -march and -mabi for RISC-V back-end, however `-print-multi-lib` will skip multi-lib setting if match any one of flag in MULTILIB_DEFAULTS, even some options are specified in the option list with '!'. e.g. We have default march=rv32i and mabi=ilp32. And we have following multi-lib set: ". !march=rv32i !march=rv32im !march=rv32imafc !mabi=ilp32 !mabi=ilp32f;" "rv32i/ilp32 march=rv32i !march=rv32im !march=rv32imafc mabi=ilp32 !mabi=ilp32f;" "rv32im/ilp32 !march=rv32i march=rv32im !march=rv32imafc mabi=ilp32 !mabi=ilp32f;" "rv32imafc/ilp32f !march=rv32i !march=rv32ic !march=rv32im march=rv32imafc !mabi=ilp32 mabi=ilp32f;" `-print-multi-lib` willl show `.` and `rv32imafc/ilp32f` only, because the mabi=ilp32 is matched, however there is `!march=rv32i` in `rv32im/ilp32`, so `rv32im/ilp32` should keep, because it reject march=rv32i.
