Thanks to the effort of @RoseZhang03 and @aaryanshukla under the guidance of @michaelrj-google and @amykhuang, we now have newhdrgen and no longer have a dependency on TableGen and thus LLVM in order to start bootstrapping a full build. This PR removes: - LIBC_HDRGEN_EXE; the in tree newhdrgen is the only hdrgen that can be used. - LIBC_USE_NEW_HEADER_GEN; newhdrgen is the default and only option. - LIBC_HDRGEN_ONLY; there is no need to have a distinct build step for old hdrgen. - libc-api-test and libc-api-test-tidy build targets. - Deletes all .td files. It does not rename newhdrgen to just hdrgen. Will follow up with a distinct PR for that. Link: llvm#117209 Fixes: llvm#117208

Unsure. Let me check the original context under which it was added.

FYI the GPU build still uses that logic to make the amdhsa-loader and nvptx-loader utilities.

right, I think I left the important bits intact in 46251c6, PTAL.

Shouldn't NEED_LIBC_HDRGEN be renamed to something else and the comment below be updated? Might want to add a TODO comment here.

nit: Add a TODO to clean this up

I tried replacing invocations of add_header_macro with just add_gen_header, but this seemed to run into issues. Not sure if every function invocation of add_gen_header would need explicit DEF_FILE and GEN_HDR spelled out?

I believe they will need explicit DEF_FILE and GEN_HDR. The macro for add_gen_header2 (lines22-29) should be used, but can be renamed to add_gen_header

Tests passed, LGTM once the buildbots are ready |

The post submit buildbots with the libc tag are all moved to newhdrgen now. I'll wait for explicit acks from @petrhosek and @jhuber6 before attempting to [crash] land this. |
