[PATCH] D55028: [gn build] Add template for running llvm-tblgen and use it to add build file for llvm/lib/IR.

[Nico Weber via Phabricator via llvm-commits]

thakis added a comment.

…wait, putting the copy-if-different logic in the tablegen runner as I did doesn't actually work, since tablegen will write the name of the temp file in the depfile this way. I'll just put a FIXME for adding write-if-different back into tablegen itself (aka reland r330742) and revert the runner script to the 2 lines it originally was. I'll upload a new patch set in an hour or two; if you look earlier please ignore run_tablegen.py (the rest will stay as-is).
