Hi,
I am using DMD 2.062 on Windows 7 64-bit.
I am writing performance critical functions that need switch
statements to use an indirect jump table... current I'm
analysing the assembly dump, and the code is compiled to
nested ifs instead. This happens with switch and final switch.
Is there any way to force the compiler to use a jump table?

Ldc or gdc may be able to do this for you if dmd cannot.
Other than that, the inline asm in dmd is easy enough to use.
Sorry, inline asm in D, not just dmd.
