This removes the recently added Valop as redundant. No functional changes. 2018-05-28 Eric Botcazou <ebotcazou@adacore.com> gcc/ada/ * repinfo.adb (List_GCC_Expression): Remove Valop and replace calls to it with calls to Unop. From-SVN: r260843

This removes the Truth_Andif_Expr and Truth_Orif_Expr codes for expressions handled by the repinfo unit, since they are redundant with Truth_And_Expr and Truth_Or_Expr respectively in this context. No functional changes. 2018-05-28 Eric Botcazou <ebotcazou@adacore.com> gcc/ada/ * repinfo.ads (TCode): Adjust range. (Truth_Andif_Expr): Remove. (Truth_Orif_Expr): Likewise. (Truth_And_Expr ..

2018-05-28 Ed Schonberg <schonberg@adacore.com> gcc/ada/ * exp_unst.adb (Visit_Node): For indexed components and attribute references, examine index expressions or associated expressions as well to record uplevel references. (Vist_Node): For function and procedure calls, if a formal is an unconstrained array and the actual is constrained, check whether bounds of actual have uplevel references. From-SVN: r260841

2018-05-28 Ed Schonberg <schonberg@adacore.com> gcc/ada/ * einfo.ads, einfo.adb: Exceptions can be uplevel references, and thus they can appear as components of activation records. * exp_unst.adb (Visit_Node): A reference to an exception may be an uplevel reference. From-SVN: r260840

This adjusts the previous change to the cases where the array type is not yet frozen and, therefore, where Size_Depends_On_Discriminant is not yet computed, by doing the computation manually. 2018-05-28 Eric Botcazou <ebotcazou@adacore.com> gcc/ada/ * exp_ch4.adb (Expand_Composite_Equality): Compute whether the size depends on a discriminant manually instead of using the predicate Size_Depends_On_Discriminant in the array type case. gcc/testsuite/ * gnat.dg/renaming12.adb, gnat.dg/renaming12.ads: New testcase. From-SVN: r260839

2018-05-28 Javier Miranda <miranda@adacore.com> gcc/ada/ * exp_ch4.adb (Real_Range_Check): Add a temporary to store the integer value when converting a float value to a fixed-point value. This is required for CCG because it handles fixed-point types by means of unsigned integer type variables. The range check is now performed using the integer value stored in this temporary. From-SVN: r260837

SPARK Reference Manual changed to accept attributes First, Last and Length as not leading to an evaluation of a part of the prefix object. This is reflected here in the checking code for that rule. 2018-05-28 Yannick Moy <moy@adacore.com> gcc/ada/ * sem_util.adb (Is_OK_Volatile_Context): Add attributes First, Last and Length as valid non-interfering contexts for SPARK. From-SVN: r260836

This fixes a long-standing issue with the expansion of equality functions generated for discriminated record types with variant part. In this case the front-end recursively expands equality functions for the composite sub-components, in particular the array sub-components. But it systematically uses the unconstrained base type for them, which leads to both a more complex equality function, because of the need to compare the bounds, and an additional unchecked conversion from type to base type. Now this unchecked conversion may block a further expansion of the array sub-component, for example if it is a large array of record types subject to a component clause that causes it not to start on a byte boundary, and thus may lead to an internal error downstream in the back-end. 2018-05-28 Eric Botcazou <ebotcazou@adacore.com> gcc/ada/ * exp_ch4.adb (Expand_Composite_Equality): For a composite (or FP) component type, do not expand array equality using the unconstrained base type, except for the case where the bounds of the type depend on a discriminant. gcc/testsuite/ * gnat.dg/rep_clause6.adb, gnat.dg/rep_clause6.ads: New testcase. From-SVN: r260834

2018-05-28 Ed Schonberg <schonberg@adacore.com> gcc/ada/ * einfo.ads, einfo.adb (Needs_Activation_Record): New flag on access-to-subprogram types, to indicate that an indirect call through such a type requires an activation record when compiling for LLVM. * sem_ch3.adb (Access_Subprogram_Declaration): Set new flag as needed. From-SVN: r260833

This patch improves the accuracy of conversions from a floating point to a fixed point type when the fixed point type has a specified Snall that is not a power of two. Previously the conversion of Fixed_Point_Type'First to some floating point number and back to Fixed_Point_Type raised Constraint error. This result is within the accuracy imposed by tne Numerics annex of the RM but is certainly undesirable. This patch transforms the conversion to avoid extra manipulations of the 'Small of the type, so that the identity: Fixed_T (Float_T (Fixed_Val)) = Fixed_Val holds over the range of Fixed_T. 2018-05-28 Ed Schonberg <schonberg@adacore.com> gcc/ada/ * exp_ch4.adb (Real_Range_Check): Specialize float-to-fixed conversions when bounds of fixed type are static, to remove some spuerfluous implicit conversions and provide an accurate result when converting back and forth between the fixed point type and a floating point type. gcc/testsuite/ * gnat.dg/fixedpnt5.adb: New testcase. From-SVN: r260832

(Note_Uplevel_Bound): Add argument to indicate node to be replaced, if any; all callers changed. Handle N_Indexed_Component like N_Attribute_Reference. Add N_Type_Conversion case.

If call has been relocated, set first_named pointer in original node as well. From-SVN: r260830

2018-05-28 Ed Schonberg <schonberg@adacore.com> gcc/ada/ * exp_aggr.adb (Flatten): Copy tree of expression in a component association with a range or a set of discrete choices, rather than relocating the node.

This patch fixes an issue whereby the compiler would raise spurious runtime errors when an array of null-excluding components was initialized with an expression which required the secondary stack (such as with an concatination operation) due to certain generated checks which were incorrected performed on internal object declarations. 2018-05-28 Justin Squirek <squirek@adacore.com> gcc/ada/ * exp_ch3.adb (Build_Initialization_Call): Add logic to pass the appropriate actual to match new formal.

This changes the output of -gnatR for extensions of tagged record types to avoid displaying the internal _Parent component, which overlaps with other components and is thus more confusing than helpful. For the following hierarchy: type R1 is tagged record I : Integer; end record; type R2 is new R1 with record C : Character; end record; the output -gnatR must now be: for R1'Object_Size use 128; for R1'Value_Size use 96; for R1'Alignment use 8; for R1 use record _Tag at 0 range 0 .. 63; I at 8 range 0 .. 31; end record; for R2'Object_Size use 192; for R2'Value_Size use 136; for R2'Alignment use 8; for R2 use record _Tag at 0 range 0 .. 63; I at 8 range 0 .. 31; C at 16 range 0 .. 7; end record; 2018-05-28 Eric Botcazou <ebotcazou@adacore.com> gcc/ada/ * repinfo.adb (Compute_Max_Length): Skip _Parent component.

Some static bounds of types are not recognized and evaluated as such in the semantic analysis phase of the frontend, which leads to incomplete information in GNATprove. Fix that in the GNATprove mode only, as this is not needed when full expansion is used.
