Subject: [PATCH v2 0/4] objtool build improvements
Date: Mon, 21 Nov 2022 16:11:21 -0800	[thread overview]
Message-ID: <20221122001125.765003-1-irogers@google.com> (raw)

Install libsubcmd and then get headers from there, this avoids
inadvertent dependencies on things in tools/lib. Fix V=1
support. Clean up how HOSTCC is used to override CC to avoid CFLAGS
being set for say gcc, and then CC being overridden to clang. Support
HOSTCFLAGS as a make option.

v2. Include required "tools lib subcmd: Add install target" that is
    already in Arnaldo's tree:

    When building libsubcmd.a from objtool's Makefile, clear the
    subdir to avoid it being appended onto OUTPUT and breaking the
    build.

Ian Rogers (4):
  tools lib subcmd: Add install target
  objtool: Install libsubcmd in build
  objtool: Properly support make V=1
  objtool: Alter how HOSTCC is forced
