[multiple changes]
2011-09-06 Robert Dewar <dewar@adacore.com>
* s-tpopsp-vxworks.adb, prj-nmsc.adb: Minor reformatting.
2011-09-06 Hristian Kirtchev <kirtchev@adacore.com>
* gcc-interface/trans.c (Attribute_to_gnu): New case for
attribute Descriptor_Size.
* exp_attr.adb (Expand_N_Attribute_Reference): Add processing
for attribute Descriptor_Size.
* exp_ch7.adb (Double_Size_Of): Removed.
(Make_Finalize_Address_Stmts): Remove the code which generates
an expression to calculate the dope vector of an unconstrained
array. Instead use attribute Descriptor_Size and leave the
calculation to the back end.
(Nearest_Multiple_Rounded_Up): Removed.
(Size_Of): Removed.
* sem_attr.adb (Analyze_Attribute): Add processing for attribute
Descriptor_Size. Currently the attribute is applicable only
to unconstrained arrays.
(Eval_Attribute): Add processing for
attribute Descriptor_Size.
* snames.ads-tmpl: Add a predefined name and an Attribute_Id
for Descriptor_Size.
2011-09-06 Ed Schonberg <schonberg@adacore.com>
* exp_aggr.adb: Remove useless formal.
