Fix issue with Windows paths containing spaces. Recent toolchain
refactoring (cc277de) caused a regression in the Windows build. Ensure
toolchain path utilities wrap paths in double quoted strings.

# Helper functions to identify toolchain tools.
|

#
|
||
# The functions defined in this section return a tool identifier when given a
|
||
# path to a binary. We generally check a help or version string to more reliably
|
||
# identify tools than by looking at the path alone (e.g. `gcc` on macOS is
|
||
# actually Apple Clang).
|
||
#
|
||
# Each tool-guessing function (`guess-tool-$(tool)`) takes a single argument
|
||
# giving the path to the tool to guess, and returns a non-empty value if the
|
||
# tool corresponds to the tool identifier `$(tool)`:
|
||
#
|
||
# $(call guess-tool-llvm-clang,aarch64-none-elf-gcc) # <empty>
|
||
# $(call guess-tool-gnu-gcc,aarch64-none-elf-gcc) # <non-empty>
|
||
#
|
||
# The `guess-tool` function tries to find the corresponding tool identifier
|
||
# for a tool given its path. It takes two arguments:
|
||
#
|
||
# - $(1): a list of candidate tool identifiers to check
|
||
# - $(2): the path to the tool to identify
|
||
#
|
||
# If any of the guess functions corresponding to candidate tool identifiers
|
||
# return a non-empty value then the tool identifier of the first function to do
|
||
# so is returned:
|
||
#
|
||
# $(call guess-tool,gnu-gcc llvm-clang,armclang) # <empty>
|
||
# $(call guess-tool,gnu-gcc llvm-clang,clang-14) # llvm-clang
|
||
# $(call guess-tool,gnu-gcc llvm-clang,aarch64-none-elf-gcc-12) # gnu-gcc
|
||
#
|
||
# Tools are checked in the order that they appear in `tools-$(tool-class)`, and
|
||
# the first match is returned.

# Locate and identify tools belonging to each toolchain.

#
|

# Each tool class in each toolchain receives a variable of the form
|

# `$(toolchain)-$(tool)` giving the associated path to the program. For example:

# - `aarch64-ld` gives the linker for the AArch64 toolchain,
|
||
# - `aarch32-oc` gives the object copier for the AArch32 toolchain, and

||
# - `host-cc` gives the C compiler for the host toolchain.
|
||
#
|
||
# For each of these variables, if no program path is explicitly provided by the
|
||
# parent Makefile then the C compiler is queried (if supported) for its
|
||
# location. This is done via the `guess-$(tool)-$(tool-class)` set of functions.
|
||
# For example:
|
||
#
|
||
# - `guess-arm-clang-ld` guesses the linker via Arm Clang,
|
||
# - `guess-llvm-clang-as` guesses the assembler via LLVM Clang, and
|
||
# - `guess-gnu-gcc-od` guesses the object dumper via GNU GCC.
|
||
#

# If the C compiler cannot provide the location (or the tool class is the C
|
||
# compiler), then it is assigned the value of the `$(toolchain)-$(tool)-default`
|
