Subject: [PATCH 0/2] infer CROSS_COMPILE from ARCH for LLVM=1 LLVM_IAS=1
Date: Wed, 7 Jul 2021 15:43:08 -0700 [thread overview]
Message-ID: <20210707224310.1403944-1-ndesaulniers@google.com> (raw)
We get constant feedback that the command line invocation of make is too
long. CROSS_COMPILE is helpful when a toolchain has a prefix of the
target triple, or is an absolute path outside of $PATH, but it's mostly
redundant for a given ARCH.
Instead, let's infer it from ARCH, and move some flag handling into a
new file included from the top level Makefile.
Nick Desaulniers (2):
Makefile: move initial clang flag handling into scripts/Makefile.clang
Makefile: drop CROSS_COMPILE for LLVM=1 LLVM_IAS=1
