Dan Gohman cf366c06d1 Optimize lseek in the tell case. ... `lseek(x, 0, SEEK_CUR)` has no effect other than to return the current file offset. The patch here uses a macro with `__builtin_constant_p` to recognize this case and rewrite it to a library call that uses `fd_tell` rather than `fd_seek`, so that programs that don't need actual seeking don't end up importing `fd_seek`. This is also the first usage of `__wasi_fd_tell` in WASI libc, so this adds it to undefined-symbols.txt.		2019-04-30 16:19:05 -07:00
