Subject: [PATCH 0/3] kconfig: Introduce cc-option-str
Date: Fri, 18 Sep 2026 17:59:24 -0700	[thread overview]
Message-ID: <20260919005923.i.879-kees@kernel.org> (raw)

Hi,

While reviewing the recent build speedup series[1], it became clear
that we needed a general solution in kconfig to avoid repeating detected
toolchain options. Implement cc-option-str and ld-option-str, and while
at it, create "def_string" and friends to match "def_bool".

-Kees

Kees Cook (3):
  kconfig: Add "def_string", "def_int" and "def_hex"
  kconfig: Replace "cc-option-bit" with "cc-option-str"
  kconfig: Add "ld-option-str"
