<H1> C.5 Pragma Discard_Names</H1>
<DIV Class="Paranum"><FONT SIZE=-2>1</FONT></DIV>
<DIV Class="Normal"> A <FONT FACE="Arial, Helvetica">pragma</FONT>
Discard_Names may be used to request a reduction in storage used for
the names of certain entities. </DIV>
<H4 ALIGN=CENTER>Syntax</H4>
<DIV Class="Paranum"><FONT SIZE=-2>2</FONT></DIV>
<DIV Class="SyntaxIndented" Style="margin-bottom: 0.2em">The form of
a <FONT FACE="Arial, Helvetica">pragma</FONT> Discard_Names is as follows:
</DIV>
<DIV Class="Paranum"><FONT SIZE=-2>3</FONT></DIV>
<DIV Class="SyntaxIndented"> <B>pragma</B> <A NAME="I6412"></A>Discard_Names[([On
=> ] <A NAME="I6413"></A><FONT FACE="Arial, Helvetica">local_name</FONT>)];</DIV>
<DIV Class="Paranum"><FONT SIZE=-2>4</FONT></DIV>
<DIV Class="SyntaxIndented">A <FONT FACE="Arial, Helvetica">pragma</FONT>
Discard_Names is allowed only immediately within a <FONT FACE="Arial, Helvetica">declarative_part</FONT>,
immediately within a <FONT FACE="Arial, Helvetica">package_specification</FONT>,
or as a configuration pragma. </DIV>
<H4 ALIGN=CENTER>Legality Rules</H4>
<DIV Class="Paranum"><FONT SIZE=-2>5</FONT></DIV>
<DIV Class="Normal"> The <FONT FACE="Arial, Helvetica">local_name</FONT>
(if present) shall denote a non-derived enumeration first subtype, a
tagged first subtype, or an exception. The pragma applies to the type
or exception. Without a <FONT FACE="Arial, Helvetica">local_name</FONT>,
the pragma applies to all such entities declared after the pragma, within
the same declarative region. Alternatively, the pragma can be used as
a configuration pragma. If the pragma applies to a type, then it applies
also to all descendants of the type. </DIV>
<H4 ALIGN=CENTER>Static Semantics</H4>
<DIV Class="Paranum"><FONT SIZE=-2>6</FONT></DIV>
<DIV Class="Normal"> <A NAME="I6414"></A><A NAME="I6415"></A>If a <FONT FACE="Arial, Helvetica">local_name</FONT>
is given, then a <FONT FACE="Arial, Helvetica">pragma</FONT> Discard_Names
is a representation pragma.</DIV>
<DIV Class="Paranum"><FONT SIZE=-2>7</FONT></DIV>
<DIV Class="Normal"> If the pragma applies to an enumeration type,
then the semantics of the Wide_Image and Wide_Value attributes are implementation
defined for that type; the semantics of Image and Value are still defined
in terms of Wide_Image and Wide_Value. In addition, the semantics of
Text_IO.Enumeration_IO are implementation defined. If the pragma applies
to a tagged type, then the semantics of the Tags.Expanded_Name function
are implementation defined for that type. If the pragma applies to an
exception, then the semantics of the Exceptions.Exception_Name function
are implementation defined for that exception.</DIV>
<H4 ALIGN=CENTER>Implementation Advice</H4>
<DIV Class="Paranum"><FONT SIZE=-2>8</FONT></DIV>
<DIV Class="Normal"> If the pragma applies to an entity, then the implementation
should reduce the amount of storage used for storing names associated
with that entity. </DIV>
