<div>I want to do a check on function parameters similar to the "<span

class="Apple-style-span"
style="font-family: Helvetica; font-size: medium;"> (r83165)<span
class="Apple-style-span" style="font-family: Menlo; font-size: 11px;">.
<font class="Apple-style-span" face="Helvetica" size="3"><span
class="Apple-style-span" style="font-size: 12px;">However, this time,
I only want to perform the check if the function has a specific
attribute. Is ActOnParamDeclarator the right place? I'm not seeing a
way to get the function attribute there. Or, any suggestion on where to
add this?</span></font></span></span></span></span></div>

ActOnParamDeclarator won't work, since that gets can get called by the
parser before we've seen the function attributes. I suggest putting
this check into ActOnFunctionDeclarator (e.g., where we check for
parameters of "void" type).

<div>Awesome, thanks! At this point in ActOnFunctionDeclarator, do
parameters know about their attributes? Specifically addr space
qualifiers. I'm thinking no because it always seems to think the
param's in addr space 0, but when I dump the QualType I can clearly see
the addr space attribute and its non zero, but I assume it just hasn't
been processed yet.</div>

ActOnFunctionDeclarator doesn't get called until all the parameters
have finished parsing, so all the attributes, address spaces, etc.
should be present.<br>
<br>
Can you post a code example where it thinks the parameter is in address
space 0 (I assume getAddressSpace() is returning 0)?<br>
