<title>Type Information for foo.c</title>  

<para>
  This mirrors the computations in <ulink url="AST.xml"/> but done via the
  Intermediate Representation (IR) from compiling the C code,
  rather than Abstract Syntax Tree of the C code.
</para>

<section>
<title>foo</title>

<para>
<r:code>
library(Rllvm)
m = parseIR("foo.ir")  
m$ifoo
</r:code>

<r:code>
source("getType.R")
compReturnType(m$ifoo)
</r:code>
This is a scalar integer.
</para>



<para>
The same works for m$ifoo2 and gives the same result:
<r:code>
compReturnType(m$ifoo2)
</r:code>  
</para>


<para>
The str routine yields a STRSXP with length 1:  
<r:code>
compReturnType(m$str)
</r:code>
</para>


<para>
compReturnType(m$len_character)
</para>
