Subject: [PATCH 1/5] scripts/gdb: delay generation of gdb constants.py
Date: Tue, 19 Feb 2019 18:33:02 +0900 [thread overview]
Message-ID: <1550568787-18710-1-git-send-email-yamada.masahiro@socionext.com> (raw)
scripts/gdb/linux/constants.py is never used in the kernel build
process. There is no good reason to create it so early.
Get it out of the 'prepare' stage.
