+# External toolchain package infrastructure
+#
+# This package infrastructure implements the support for external
+# toolchains, i.e toolchains that are available pre-built, ready to
+# use. Such toolchain may either be readily available on the Web
+# (Linaro, Sourcery CodeBench, from processor vendors) or may be built
+# with tools like Crosstool-NG or Buildroot itself. So far, we have
+# tested this with:
+#
+# * Toolchains generated by Crosstool-NG
+# * Toolchains generated by Buildroot
+# * Toolchains provided by Linaro for the ARM and AArch64
+# architectures
+# * Sourcery CodeBench toolchains (from Mentor Graphics) for the ARM,
+# MIPS, PowerPC, x86, x86_64 and NIOS 2 architectures. For the MIPS
+# toolchain, the -muclibc variant isn't supported yet, only the
+# default glibc-based variant is.
+# * Xilinx toolchains for the Microblaze architecture
+# * Synopsys DesignWare toolchains for ARC cores
+#
+# The basic principle is the following
+#
+# 1. If the toolchain is not pre-installed, download and extract it
+# in $(TOOLCHAIN_EXTERNAL_INSTALL_DIR). Otherwise,
+# $(TOOLCHAIN_EXTERNAL_INSTALL_DIR) points to were the toolchain has
+# already been installed by the user.
+#
+# 2. For all external toolchains, perform some checks on the
+# conformity between the toolchain configuration described in the
+# Buildroot menuconfig system, and the real configuration of the
+# external toolchain. This is for example important to make sure that
+# the Buildroot configuration system knows whether the toolchain
+# supports RPC, IPv6, locales, large files, etc. Unfortunately, these
+# things cannot be detected automatically, since the value of these
+# options (such as BR2_TOOLCHAIN_HAS_NATIVE_RPC) are needed at
+# configuration time because these options are used as dependencies
+# for other options. And at configuration time, we are not able to
+# retrieve the external toolchain configuration.
+#
+# 3. Copy the libraries needed at runtime to the target directory,
+# $(TARGET_DIR). Obviously, things such as the C library, the dynamic
+# loader and a few other utility libraries are needed if dynamic
+# applications are to be executed on the target system.
+#
+# 4. Copy the libraries and headers to the staging directory. This
+# will allow all further calls to gcc to be made using --sysroot
+# $(STAGING_DIR), which greatly simplifies the compilation of the
+# packages when using external toolchains. So in the end, only the
+# cross-compiler binaries remains external, all libraries and headers
+# are imported into the Buildroot tree.
+#
+# 5. Build a toolchain wrapper which executes the external toolchain
+# with a number of arguments (sysroot/march/mtune/..) hardcoded,
+# so we're sure the correct configuration is always used and the
+# toolchain behaves similar to an internal toolchain.
+# This toolchain wrapper and symlinks are installed into
+# $(HOST_DIR)/usr/bin like for the internal toolchains, and the rest
+# of Buildroot is handled identical for the 2 toolchain types.

+# Various utility functions used by the external toolchain package
+# infrastructure. Those functions are mainly responsible for:
+#
+# - installation the toolchain libraries to $(TARGET_DIR)
+# - copying the toolchain sysroot to $(STAGING_DIR)
+# - installing a gdbinit file
+#
+# Details about sysroot directory selection.
+#
+# To find the sysroot directory, we use the trick of looking for the
+# 'libc.a' file with the -print-file-name gcc option, and then
+# mangling the path to find the base directory of the sysroot.
+#
+# Note that we do not use the -print-sysroot option, because it is
+# only available since gcc 4.4.x, and we only recently dropped support
+# for 4.2.x and 4.3.x.
+#
+# When doing this, we don't pass any option to gcc that could select a
+# multilib variant (such as -march) as we want the "main" sysroot,
+# which contains all variants of the C library in the case of multilib
+# toolchains. We use the TARGET_CC_NO_SYSROOT variable, which is the
+# path of the cross-compiler, without the --sysroot=$(STAGING_DIR),
+# since what we want to find is the location of the original toolchain
+# sysroot. This "main" sysroot directory is stored in SYSROOT_DIR.
+#
+# Then, multilib toolchains are a little bit more complicated, since
+# they in fact have multiple sysroots, one for each variant supported
+# by the toolchain. So we need to find the particular sysroot we're
+# interested in.
+#
+# To do so, we ask the compiler where its sysroot is by passing all
+# flags (including -march and al.), except the --sysroot flag since we
+# want to the compiler to tell us where its original sysroot
+# is. ARCH_SUBDIR will contain the subdirectory, in the main
+# SYSROOT_DIR, that corresponds to the selected architecture
+# variant. ARCH_SYSROOT_DIR will contain the full path to this
+# location.
+#
+# One might wonder why we don't just bother with ARCH_SYSROOT_DIR. The
+# fact is that in multilib toolchains, the header files are often only
+# present in the main sysroot, and only the libraries are available in
+# each variant-specific sysroot directory.
+
+
+# toolchain_find_sysroot returns the sysroot location for the given
+# compiler + flags. We need to handle cases where libc.a is in:
+#
+# - lib/
+# - usr/lib/
+# - lib32/
+# - lib64/
+# - lib32-fp/ (Cavium toolchain)

+# SYSROOT_DIR: the main sysroot directory, deduced from

+# usr/lib[32|64]/libc.a part of the path.
+# Ex: /x-tools/mips-2011.03/mips-linux-gnu/libc/
+#
+# ARCH_LIBC_A_LOCATION: location of the libc.a file in the selected
+# multilib variant (taking into account the
+# CFLAGS). Allows to find the sysroot of the
+# selected multilib variant.
+# Ex: /x-tools/mips-2011.03/mips-linux-gnu/libc/mips16/soft-float/el/usr/lib/libc.a
+#
+# ARCH_SYSROOT_DIR: the sysroot of the selected multilib variant,

+# Ex: /x-tools/mips-2011.03/mips-linux-gnu/libc/mips16/soft-float/el/
+#
+# ARCH_LIB_DIR: 'lib', 'lib32' or 'lib64' depending on where libraries
+# are stored. Deduced from ARCH_LIBC_A_LOCATION by
+# looking at usr/lib??/libc.a.
+# Ex: lib
+#
+# ARCH_SUBDIR: the relative location of the sysroot of the selected
+# multilib variant compared to the main sysroot.
+# Ex: mips16/soft-float/el
+#
+# SUPPORT_LIB_DIR: some toolchains, such as recent Linaro toolchains,
+# store GCC support libraries (libstdc++,
+# libgcc_s, etc.) outside of the sysroot. In
+# this case, SUPPORT_LIB_DIR is set to a
+# non-empty value, and points to the directory
+# where these support libraries are
+# available. Those libraries will be copied to
+# our sysroot, and the directory will also be
+# considered when searching libraries for copy
+# to the target filesystem.
+#
+# Please be very careful to check the major toolchain sources:
+# Buildroot, Crosstool-NG, CodeSourcery and Linaro
+# before doing any modification on the below logic.

################################################################################
-#
-# This package implements the support for external toolchains, i.e
-# toolchains that are available pre-built, ready to use. Such toolchain
-# may either be readily available on the Web (Linaro, Sourcery
-# CodeBench, from processor vendors) or may be built with tools like
-# Crosstool-NG or Buildroot itself. So far, we have tested this
-# with:
-#
-# * Toolchains generated by Crosstool-NG
-# * Toolchains generated by Buildroot
-# * Toolchains provided by Linaro for the ARM and AArch64
-# architectures
-# * Sourcery CodeBench toolchains (from Mentor Graphics) for the ARM,
-# MIPS, PowerPC, x86, x86_64 and NIOS 2 architectures. For the MIPS
-# toolchain, the -muclibc variant isn't supported yet, only the
-# default glibc-based variant is.
-# * Analog Devices toolchains for the Blackfin architecture
-# * Xilinx toolchains for the Microblaze architecture
-# * Synopsys DesignWare toolchains for ARC cores
-#
-# The basic principle is the following
-#
-# 1. If the toolchain is not pre-installed, download and extract it
-# in $(TOOLCHAIN_EXTERNAL_INSTALL_DIR). Otherwise,
-# $(TOOLCHAIN_EXTERNAL_INSTALL_DIR) points to were the toolchain has
-# already been installed by the user.
-#
-# 2. For all external toolchains, perform some checks on the
-# conformity between the toolchain configuration described in the
-# Buildroot menuconfig system, and the real configuration of the
-# external toolchain. This is for example important to make sure that
-# the Buildroot configuration system knows whether the toolchain
-# supports RPC, IPv6, locales, large files, etc. Unfortunately, these
-# things cannot be detected automatically, since the value of these
-# options (such as BR2_TOOLCHAIN_HAS_NATIVE_RPC) are needed at
-# configuration time because these options are used as dependencies
-# for other options. And at configuration time, we are not able to
-# retrieve the external toolchain configuration.
-#
-# 3. Copy the libraries needed at runtime to the target directory,
-# $(TARGET_DIR). Obviously, things such as the C library, the dynamic
-# loader and a few other utility libraries are needed if dynamic
-# applications are to be executed on the target system.
-#
-# 4. Copy the libraries and headers to the staging directory. This
-# will allow all further calls to gcc to be made using --sysroot
-# $(STAGING_DIR), which greatly simplifies the compilation of the
-# packages when using external toolchains. So in the end, only the
-# cross-compiler binaries remains external, all libraries and headers
-# are imported into the Buildroot tree.
-#
-# 5. Build a toolchain wrapper which executes the external toolchain
-# with a number of arguments (sysroot/march/mtune/..) hardcoded,
-# so we're sure the correct configuration is always used and the
-# toolchain behaves similar to an internal toolchain.
-# This toolchain wrapper and symlinks are installed into
-# $(HOST_DIR)/usr/bin like for the internal toolchains, and the rest
-# of Buildroot is handled identical for the 2 toolchain types.

-# Details about sysroot directory selection.
-#
-# To find the sysroot directory, we use the trick of looking for the
-# 'libc.a' file with the -print-file-name gcc option, and then
-# mangling the path to find the base directory of the sysroot.
-#
-# Note that we do not use the -print-sysroot option, because it is
-# only available since gcc 4.4.x, and we only recently dropped support
-# for 4.2.x and 4.3.x.
-#
-# When doing this, we don't pass any option to gcc that could select a
-# multilib variant (such as -march) as we want the "main" sysroot,
-# which contains all variants of the C library in the case of multilib
-# toolchains. We use the TARGET_CC_NO_SYSROOT variable, which is the
-# path of the cross-compiler, without the --sysroot=$(STAGING_DIR),
-# since what we want to find is the location of the original toolchain
-# sysroot. This "main" sysroot directory is stored in SYSROOT_DIR.
-#
-# Then, multilib toolchains are a little bit more complicated, since
-# they in fact have multiple sysroots, one for each variant supported
-# by the toolchain. So we need to find the particular sysroot we're
-# interested in.
-#
-# To do so, we ask the compiler where its sysroot is by passing all
-# flags (including -march and al.), except the --sysroot flag since we
-# want to the compiler to tell us where its original sysroot
-# is. ARCH_SUBDIR will contain the subdirectory, in the main
-# SYSROOT_DIR, that corresponds to the selected architecture
-# variant. ARCH_SYSROOT_DIR will contain the full path to this
-# location.
-#
-# One might wonder why we don't just bother with ARCH_SYSROOT_DIR. The
-# fact is that in multilib toolchains, the header files are often only
-# present in the main sysroot, and only the libraries are available in
-# each variant-specific sysroot directory.

-# Ex: /x-tools/mips-2011.03/mips-linux-gnu/libc/usr/lib/libc.a
-#
-# SYSROOT_DIR: the main sysroot directory, deduced from
-# LIBC_A_LOCATION by removing the
-# usr/lib[32|64]/libc.a part of the path.
-# Ex: /x-tools/mips-2011.03/mips-linux-gnu/libc/
-#
-# ARCH_LIBC_A_LOCATION: location of the libc.a file in the selected
-# multilib variant (taking into account the
-# CFLAGS). Allows to find the sysroot of the
-# selected multilib variant.
-# Ex: /x-tools/mips-2011.03/mips-linux-gnu/libc/mips16/soft-float/el/usr/lib/libc.a
-#
-# ARCH_SYSROOT_DIR: the sysroot of the selected multilib variant,
-# deduced from ARCH_LIBC_A_LOCATION by removing
-# usr/lib[32|64]/libc.a at the end of the path.
-# Ex: /x-tools/mips-2011.03/mips-linux-gnu/libc/mips16/soft-float/el/
-#
-# ARCH_LIB_DIR: 'lib', 'lib32' or 'lib64' depending on where libraries
-# are stored. Deduced from ARCH_LIBC_A_LOCATION by
-# looking at usr/lib??/libc.a.
-# Ex: lib
-#
-# ARCH_SUBDIR: the relative location of the sysroot of the selected
-# multilib variant compared to the main sysroot.
-# Ex: mips16/soft-float/el
-#
-# SUPPORT_LIB_DIR: some toolchains, such as recent Linaro toolchains,
-# store GCC support libraries (libstdc++,
-# libgcc_s, etc.) outside of the sysroot. In
-# this case, SUPPORT_LIB_DIR is set to a
-# non-empty value, and points to the directory
-# where these support libraries are
-# available. Those libraries will be copied to
-# our sysroot, and the directory will also be
-# considered when searching libraries for copy
-# to the target filesystem.
-#
-# Please be very careful to check the major toolchain sources:
-# Buildroot, Crosstool-NG, CodeSourcery and Linaro
-# before doing any modification on the below logic.
