2004-05-24 Geert Bosch <bosch@gnat.com> * a-numaux-x86.adb (Reduce): Reimplement using an approximation of Pi with 192 bits of precision, sufficient to reduce a double-extended arguments X with a maximum relative error of T'Machine_Epsilon, for X in -2.0**32 .. 2.0**32. (Cos, Sin): Always reduce arguments of 1/4 Pi or larger, to prevent reduction by the processor, which only uses a 68-bit approximation of Pi. (Tan): Always reduce arguments and compute function either using the processor's fptan instruction, or by dividing sin and cos as needed. 2004-05-24 Doug Rupp <rupp@gnat.com> * adaint.c (__gnat_readdir): Cast CRTL function retun value to avoid gcc error on 32/64 bit VMS. 2004-05-24 Olivier Hainque <hainque@act-europe.fr> * init.c (__gnat_error_handler): Handle EEXIST as EACCES for SIGSEGVs, since this is what we get for stack overflows although not documented as such. Document the issues which may require adjustments to our signal handlers. 2004-05-24 Ed Schonberg <schonberg@gnat.com> * inline.adb (Add_Scope_To_Clean): Do not add cleanup actions to the enclosing dynamic scope if the instantiation is within a generic unit. 2004-05-24 Arnaud Charlet <charlet@act-europe.fr> * exp_dbug.ads: Fix typo. * Makefile.in: s-osinte-linux-ia64.ads was misnamed. Rename it to its proper name: system-linux-ia64.ads (stamp-gnatlib1): Remove extra target specific run time files when setting up the rts directory. 2004-05-24 Javier Miranda <miranda@gnat.com> * einfo.ads, einfo.adb (Limited_Views): Removed. (Limited_View): New attribute that replaces the previous one. It is now a bona fide package with the limited-view list through the first_entity and first_private attributes. * sem_ch10.adb (Install_Private_With_Clauses): Give support to limited-private-with clause. (Install_Limited_Withed_Unit): Install the private declarations of a limited-private-withed package. Update the installation of the shadow entities according to the new structure (see Build_Limited_Views) (Build_Limited_Views): Replace the previous implementation of the limited view by a package entity that references the first shadow entity plus the first shadow private entity (required for limited- private-with clause) (New_Internal_Shadow_Entity): Code cleanup. (Remove_Limited_With_Clause): Update the implementation to undo the new work carried out by Build_Limited_Views. (Build_Chain): Complete documentation. Replace Ada0Y by Ada 0Y in comments Minor reformating * sem_ch3.adb (Array_Type_Declaration): In case of anonymous access types the level of accessibility depends on the enclosing type declaration. * sem_ch8.adb (Find_Expanded_Name): Fix condition to detect shadow entities. Complete documentation of previous change. 2004-05-24 Robert Dewar <dewar@gnat.com> * namet.adb: Minor reformatting Avoid use of name I (replace by J) Minor code restructuring * sem_ch6.adb: Minor reformatting * lib-writ.adb: Do not set restriction as active if this is a Restriction_Warning case. * sem_prag.adb: Reset restriction warning flag if real pragma restriction encountered. * s-htable.adb: Minor reformatting Change rotate count to 3 in Hash (improves hash for small strings) * 5qsystem.ads: Add comments for type Address (no literals allowed). * gnat_ugn.texi: Add new section of documentation "Code Generation Control", which describes the use of -m switches. 2004-05-24 Eric Botcazou <ebotcazou@act-europe.fr> (tree_transform) <N_Identifier>: Do the dereference directly through the DECL_INITIAL for renamed variables.
