2012-01-30 Robert Dewar <dewar@adacore.com>
* a-cdlili.adb, a-cidlli.adb, a-cbdlli.adb: Minor reformatting.
2012-01-30 Olivier Hainque <hainque@adacore.com>
* sigtramp-ppcvxw.c (CFI_COMMON_REGS): Add rule for r1 back +
comments.
2012-01-30 Thomas Quinot <quinot@adacore.com>
* gnat_rm.texi, sem_dist.adb, sem_dist.ads, einfo.ads, sem_prag.adb,
sem_ch12.adb, sem_attr.adb, aspects.adb, aspects.ads, par-prag.adb,
sem_cat.adb, snames.ads-tmpl (Sem_Dist.Is_Valid_Remote_Object_Type):
New subprogram (extracted from
Sem_Cat.Validate_Remote_Access_Object_Type_Declaration).
(Einfo.Is_Remote_Types): Now applies to generic types. Update
documentation accordingly.
(Sem_Ch12.Analyze_Associations): A RACW type is acceptable as
actual for a formal type to which a pragma Remote_Access_Type
applies.
(Aspects, Par.Prag, Sem_Prag): Support for new pramga/aspect
Remote_Access_Type.
(Sem_Attr.Analyze_Attribute, case Stub_Type): Attribute can
be applied to a generic type if pragma Remote_Access_Type
applies, in which case the type of the attribute is
System.Partition_Interface.RACW_Stub_Type.
