[cfe-dev] Help with APValue comparisons

[Andy Gibbs]

Hi,

I'm in the middle of cooking a patch which dramatically speeds up 
compilation of constexpr functions.  I have a partially working patch 
already which "fixes" the bug at http://llvm.org/bugs/show_bug.cgi?id=12850. 
I put "fixes" in quotes because at present the fix only works for the 
"simple" cases as present, by which I mean where arguments evaluate to 
APValues of type interger / float / complex / array / vector / struct.

The question I have is this: the above cases have, lets say, fairly obvious 
ways for comparing whether two APValues are the same, however, I'm not sure 
about LValue -- does anyone know of a suitable / correct way of comparing 
two LValue-type APValues?

Many thanks!

Andy
