2007-04-06 Geert Bosch <bosch@adacore.com> Ed Schonberg <schonberg@adacore.com> Javier Miranda <miranda@adacore.com> Bob Duff <duff@adacore.com> * exp_ch4.adb (Expand_N_Type_Conversion): Remove special processing for conversion of a Float_Type'Truncation to integer. * exp_attr.adb (Is_Inline_Floating_Point_Attribute): New function to check if a node is an attribute that can be handled directly by the back end. (Expand_N_Attribute_Reference): Suppress expansion of floating-point attributes that can be handled directly by the back end. (Expand_N_Attribute_Reference, case 'Access and 'Unchecked_Access): use new predicate Is_Access_Protected_Subprogram_Type. (Expand_N_Attribute_Reference, case 'Write): The reference is legal for and Unchecked_Union if it is generated as part of the default Output procedure for a type with default discriminants. (Expand_N_Attribute_Reference): Avoid the expansion of dispatching calls if we are compiling under restriction No_Dispatching_Calls. (Constrained): Use Underlying_Type, in case the type is private without discriminants, but the full type has discriminants. (Expand_N_Attribute_Reference): Replace call to Get_Access_Level by call to Build_Get_Access_Level. (Expand_N_Attribute_Reference): The use of 'Address with class-wide interface objects requires a call to the run-time subprogram that returns the base address of the object. (Valid_Conversion): Improve error message on illegal attempt to store an anonymous access to subprogram value into a record component. * sem_res.adb (Resolve_Equality_Op): Detect ambiguity for "X'Access = null". (Simplify_Type_Conversion): New procedure that performs simplification of Int_Type (Float_Type'Truncation (X)). (Resolve_Type_Conversion): Call above procedure after resolving operand and before performing checks. This replaces the existing ineffective code in Exp_Ch4. (Set_String_Literal_Subtype): When creating the internal static lower bound subtype for a string literal, use a newly created copy of the subtree representing the lower bound. (Resolve_Call): Exclude build-in-place function calls from transient scope treatment. Update comments to describe this exception. (Resolve_Equality_Op): In case of dispatching call check violation of restriction No_Dispatching_Calls. (Resolve_Call): If the call returns an array, the context imposes the component type of the array, and the function has one non-defaulted parameter, rewrite the call as the indexing of a call with a single parameter, to handle an Ada 2005 syntactic ambiguity for calls written in prefix form. (Resolve_Actuals): If an actual is an allocator for an access parameter, the master of the created object is the innermost enclosing statement. (Remove_Conversions): For a binary operator, check if type of second formal is numeric, to check if an abstract interpretation is present in the case of exponentiation as well. From-SVN: r123552 |

This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the file COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs.html for how to report bugs usefully.
