exp_strm.adb, aa_drive.adb: Minor reformatting.
* sem_res.adb (Is_Predefined_Operator): An operator that is an imported
intrinsic with an Interface_Name denotes an imported back-end builtin,
and must be rewritten into a call, not left in the tree as an operator,
so return False in that case.

-- SCO information can exist in one of two forms. In the ALI file, it is

-- Internally it is stored using two tables SCO_Table and SCO_Unit_Table,

|
|
|
|
|
-- In several places in the SCO lines, Sloc ranges appear. These are used
|
|
|
|
-- to indicate the first and last Sloc of some construct in the tree and
|
|
|
|
-- they have the form:
|
|
|
|
|
|
|
|
-- line:col-line:col
|
|
|
|
|
|
|
|
-- Note that SCO's are generated only for generic templates, not for
|
|
|
|
-- generic instances (since only the first are part of the source). So
|
|
|
|
-- we don't need generic instantiation stuff in these line:col items.

-- The SCO information follows the cross-reference information, so it
|
|
|
|
-- need not be read by tools like gnatbind, gnatmake etc. The SCO output
|
|
|
|
-- is divided into sections, one section for each unit for which SCO's
|
|
|
|
-- are generated. A SCO section has a header of the form:
|
|
|
|
|
2009-11-30 14:52:35 +01:00
|
|
|
-- C dependency-number filename
|

|
|
|
|
|
|
|
-- This header precedes SCO information for the unit identified by
|
|
|
|
-- dependency number and file name. The dependency number is the
|
|
|
|
-- index into the generated D lines and is ones origin (i.e. 2 =
|
|
|
|
-- reference to second generated D line).
|
|
|
|
|
|
|
|
-- Note that the filename here will reflect the original name if
|
|
|
|
-- a Source_Reference pragma was encountered (since all line number
|
|
|
|
-- references will be with respect to the original file).
|
|
|
|
|
2009-07-23 14:41:47 +02:00
|
|
|
-- Note: the filename is redundant in that it could be deduced from
|
|
|
|
-- the corresponding D line, but it is convenient at least for human
|
|
|
|
-- reading of the SCO information, and means that the SCO information
|
|
|
