search for: sizeof_byte

...;. So this means that the sizeof a char (and an int and a short for that matter) is 24-bits. I quickly read the posted link WritingAnLLVMBackend.html but did not see an obvious answer to the following question: Is it possible to write a backend that faithfully represents these architectures or is sizeof_byte==8 bits baked into to llvm? Does anyone have any views on the above? thanks Matthew Gardiner On Tue, 9 Sep 2014 18:21:01 +1200 Bruce Hoult <bruce at hoult.org> wrote: > http://llvm.org/docs/WritingAnLLVMBackend.html > > > On Tue, Sep 9, 2014 at 6:09 PM, Prakash Premkumar &...

How does LLVM generate machine code for different architectures? For example, the machine code for x86 and amd will vary. How does LLVM convert its IR to machine code for different architectures.Can you please explain the approach? Is it just write two different programs for two different architectures and pass a flag to the compiler based on which machine code you want to generate? Thanks a lot
