llvm dev - Jun 2006 - [LLVMdev] size of generated machine code ?

Hi,

Is there a way to find out how much memory
some JIT'ed machine code uses ?

Simon.

lli -stats x.bc <args>

the -stats output will indicate the # bytes of machine code.

This from the output:

   24620 x86-emitter           - Number of machine instructions emitted

(i had to write a dummy main function to get this to work)

Is this really the number of bytes of machine code ?

thanks,

Simon.
