According to the CMake docs, this is the correct way to setup a
toolchain file for cross-compilation using Clang. See
https://cmake.org/cmake/help/latest/manual/cmake-toolchains.7.html#cross-compiling-using-clang
Internally it looks like CMake will only take this variable into account
if it detects the compiler to be Clang, so this shouldn't effect other
builds, but in the case of our Apple cross builds, we'd end up with a
duplicated `--target=arm64-apple-darwin` on the compiler line, given we
are already setting `--target` for Darwin builds.
Would fix #31748.

# Pattern rule to print variables, e.g. make print-top_srcdir

print-%: FORCE

@echo '$*'='$($*)'
|
|
|
|
# When invoking a sub-make, keep only the command line variable definitions
|
|
# matching the pattern in the filter function.
|
|
#
|
|
# e.g. invoking:
|
|
# $ make A=1 C=1 print-MAKEOVERRIDES print-MAKEFLAGS
|
|
#
|
|
# with the following in the Makefile:
|
|
# MAKEOVERRIDES := $(filter A=% B=%,$(MAKEOVERRIDES))
|
|
#
|
|
# will print:
|
|
# MAKEOVERRIDES = A=1
|
|
# MAKEFLAGS = -- A=1
|
|
#
|
|
# this is because as the GNU make manual says:
|
|
# The command line variable definitions really appear in the variable
|
|
# MAKEOVERRIDES, and MAKEFLAGS contains a reference to this variable.
|
|
#
|
|
# and since the GNU make manual also says:
|
|
# variables defined on the command line are passed to the sub-make through
|
|
# MAKEFLAGS
|
|
#
|
|
# this means that sub-makes will be invoked as if:
|
|
# $(MAKE) A=1 blah blah
|
|
MAKEOVERRIDES := $(filter V=%,$(MAKEOVERRIDES))

# Previously, we directly invoked the well-known programs using $(shell ...)
|
|
# to construct build_id_string. However, that was problematic because:
|
|
#
|
|
# 1. When invoking a shell, GNU Make special-cases exit code 127 (command not
|
|
# found) by not capturing the output but instead passing it through. This is
|
|
# not done for any other exit code.
|
|
#
|
|
# 2. Characters like '#' (from these programs' output) would end up in make
|
|
# variables like build_id_string, which would be wrongly interpreted by make
|
|
# when these variables were used.
|
|
#
|
|
# Therefore, we should avoid having arbitrary strings in make variables where
|
|
# possible. The gen_id script used here hashes the output to construct a
|
|
# "make-safe" id.
|
|

|

# 2. Before including packages/*.mk (excluding packages/packages.mk), since

|
# they rely on the build_id variables
