[llvm-dev] Extending TableGen's 'foreach' to work with 'multiclass' and 'defm'

[Martin J. O'Riordan via llvm-dev]

Yes, this is very true.  I am only recently in a company that can afford the cost of these tools :-) when I was in "start-up land" it was not accessible to me.

Do you know if the Synopsis tools is regularly tracking LLVM versions?

Thanks,

The Synopsis toolchain with their Lisa HDL can generate a TableGen back end for LLVM from the instruction descriptions.
