[LLVMdev] HUGE_VALF in OSX

[Peter Lawrence]

all,
      this is all probably very old news and probably fixed in a  
later OSX, but.....
on my 10.4.11 machine,   math.h  has  (IMHO this bug)

#define HUGE_VALF  1e50f

this compiles when I build LLVM using "configure", but not with  
"cmake", probably
to do with different  C-standard-ness and pedantic-ness switches....

I would recommend LLVM Support not import the HUGE_VAL, HUGE_VALF  
feature,
and instead use its own definition,  I redefined HUGE_VALF in Support/ 
DataTypes.h
{.in,.cmake} to be 3.4e38f and got LLVM to build on 10.4.11 that way.

sincerely,
Peter Lawrence.
