2012-12-05 Ed Schonberg <schonberg@adacore.com> * sem_eval.adb: Remove spurious warnings. 2012-12-05 Ed Schonberg <schonberg@adacore.com> * sem_util.adb (Build_Explicit_Dereference): Set properly the type of the prefix prior to rewriting, because subsequent legality checks examine the original node. 2012-12-05 Hristian Kirtchev <kirtchev@adacore.com> * aspects.adb: Add Contract_Cases to the canonical aspects map. * aspects.ads: Add aspect Contract_Cases in the various aspect tables. * par-prag.adb: The parser does not need to perform special actions for pragma Contract_Cases. * sem_ch6.adb (Expand_Contract_Cases): New routine. (Process_Contract_Cases): Convert pragma Contract_Cases into pre- and post- condition checks that verify the runtime state of all case guards and their corresponding consequences. * sem_ch13.adb (Analyze_Aspect_Specifications): Perform various legality checks on aspect Contract_Cases. The aspect is transformed into a pragma. * sem_prag.adb: Add an entry in table Sig_Flags for pragma Contract_Cases. (Analyze_Pragma): Perform various legality checks on pragma Contract_Cases. The pragma is associated with the contract of the related subprogram. (Chain_CTC): Omit pragma Contract_Cases because it does not introduce a unique case name and does not follow the syntax of Contract_Case and Test_Case. * snames.ads-tmpl: Add new name Name_Contract_Cases. Add a Pragma_Id for Contract_Cases. 2012-12-05 Thomas Quinot <quinot@adacore.com> * sem_ch5.adb: Minor reformatting. 2012-12-05 Hristian Kirtchev <kirtchev@adacore.com> * sem_attr.ads: Add an entry for attribute Loop_Entry in the Attribute_Impl_Def table. 2012-12-05 Bob Duff <duff@adacore.com> * gnatchop.adb (Read_File): Avoid storage leak, and in most cases avoid an extra copy of the string.

2012-11-06 Geert Bosch <bosch@adacore.com> * eval_fat.adb (Machine, Succ): Fix front end to support static evaluation of attributes on targets with both VAX and IEEE float. * sem_util.ads, sem_util.adb (Has_Denormals, Has_Signed_Zeros): New type-specific functions. Previously we used Denorm_On_Target and Signed_Zeros_On_Target directly, but that doesn't work well for OpenVMS where a single target supports both floating point with and without signed zeros. * sem_attr.adb (Attribute_Denorm, Attribute_Signed_Zeros): Use new Has_Denormals and Has_Signed_Zeros functions to support both IEEE and VAX floating point on a single target. 2012-11-06 Tristan Gingold <gingold@adacore.com> * bindgen.adb (System_Interrupts_Used): New variable. (Gen_Adainit): Declare and call Install_Restricted_Handlers_Sequential if System.Interrupts is used when elaboration policy is sequential. 2012-11-06 Ed Schonberg <schonberg@adacore.com> * sem_ch8.adb: Complete previous change.

Attribute_Definition. 2012-10-29 Thomas Quinot <quinot@adacore.com> * gnat_rm.texi, sem_prag.adb, sem_util.adb, sem_util.ads, par-prag.adb, par-util.adb, snames.ads-tmpl (Sem_Prag.Analyze_Pragma): Handle new pragma Attribute_Definition. (Sem_Util.Bad_Attribute): New routine, moved here from par-util, so that it can be used by the above. (Par_Util.Signal_Bad_Attribute): Processing moved to Sem_Util.Bad_Attribute. From-SVN: r192935

2012-10-05 Robert Dewar <dewar@adacore.com> * sem_util.adb (Has_One_Matching_Field): Handle case of lone discriminant. 2012-10-05 Yannick Moy <moy@adacore.com> * checks.adb (Minimize_Eliminate_Overflow_Checks): Correct code for the division operation and exponent operation. Adjust bound for the mod and rem operations. From-SVN: r192126

2012-10-04 Vincent Celier <celier@adacore.com> * prj-proc.adb (Recursive_Process): Use project directory display path name as the value of 'Project_Dir. 2012-10-04 Robert Dewar <dewar@adacore.com> * exp_ch4.adb (Expand_Compare_Minimize_Eliminate_Overflow): Deal with case where we get a bignum operand and cannot do a range analysis. * sem_eval.adb (Why_Not_Static): Deal with bignum operands 2012-10-04 Ed Schonberg <schonberg@adacore.com> * sem_ch4.adb (Find_Unary_Types): Within an instance, an interpretation that involves a predefied arithmetic operator is not a candidate if the corresponding generic formal type is not a numeric type. * sem_util.ads, sem_util.adb (Corresonding_Generic_Type): If a type is a generic actual type within an instance, return the corresponding formal in the generic unit, otherwise return Any_Type.
