<p class="MsoNormal"><span style="color:#212121;mso-ligatures:none"> Rajan: Constraints implementations. Macros can expand to anything (functions, global variables, magic).<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#212121;mso-ligatures:none"> Fred: OK. This is a runtime query right?<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#212121;mso-ligatures:none"> Jim: No, it is a translation time variable since it changes at different points in the program.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="color:#212121;mso-ligatures:none"> Jim: We could conceptually expand the floating point environment into translation environment as well.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#212121;mso-ligatures:none"> Rajan: May be confusing for cross-compilation.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#212121;mso-ligatures:none"> Fred: The subnormal one changes the floating point environment.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#212121;mso-ligatures:none"> Jim: It may underneath the covers. Like the round pragmas which does not require dynamic environment changing, but can be by an implementation.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#212121;mso-ligatures:none"> Fred: ARM has a bit in the floating point environment that says whether to flush subnormals or not.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#212121;mso-ligatures:none"> Jim: Looking at current and alternative 1, leaning towards current. Let's review it later.<o:p></o:p></span></p>
