Hi, i'm currently building a small JIT compiler. For the language I need a runtime library for some special math functions. I think the best would be to compile the lib to bitcode and link it. The compiler should be integrated in a product and as of this, it must work under windows (VC10, 64bit). So is it possible to build the math lib with the mingw llvm-gcc build an link it later with the

Hi, i need to check if an overflow of an floating-point arithmetic operation occured. Currently I'm doing something like this (for addition): (LHS > 0 && RHS > 0 && sum <= 0) || (LHS < 0 && RHS < 0 && sum >= 0) This is checked for every addition. Is there a more efficient way like the intrisic for int overflow? How is it possible to raise a

...that the result is infinte, but there are sill flags in the FPU which indicate that an overflow, underflow or div by zero occured. So isn't there an easy way to check if one of those flags is set? 2010/7/23 John McCall <rjmccall at apple.com> > On Jul 23, 2010, at 7:20 AM, Steffen Geißinger wrote: > > i need to check if an overflow of an floating-point arithmetic operation > occured. > Currently I'm doing something like this (for addition): > > (LHS > 0 && RHS > 0 && sum <= 0) || (LHS < 0 && RHS < 0 && sum >= 0)...
