-# @ECLASS-VARIABLE: MULTILIB_COMPAT
-# @DEFAULT_UNSET
-# @DESCRIPTION:
-# List of multilib ABIs supported by the ebuild. If unset, defaults to
-# all ABIs supported by the eclass.
-#
-# This variable is intended for use in prebuilt multilib packages that
-# can provide binaries only for a limited set of ABIs. If ABIs need to
-# be limited due to a bug in source code, package.use.mask is to be used
-# instead. Along with MULTILIB_COMPAT, KEYWORDS should contain '-*'.
-#
-# Note that setting this variable effectively disables support for all
-# other ABIs, including other architectures. For example, specifying
-# abi_x86_{32,64} disables support for MIPS as well.
-#
-# The value of MULTILIB_COMPAT determines the value of IUSE. If set, it
-# also enables REQUIRED_USE constraints.
-#
-# Example use:
-# @CODE
-# # Upstream provides binaries for x86 & amd64 only
-# MULTILIB_COMPAT=( abi_x86_{32,64} )
-# @CODE
-
-# @ECLASS-VARIABLE: MULTILIB_USEDEP
-# @OUTPUT_VARIABLE
-# @DESCRIPTION:
-# The USE-dependency to be used on dependencies (libraries) needing
-# to support multilib as well.
-#
-# Example use:
-# @CODE
-# RDEPEND="dev-libs/libfoo[${MULTILIB_USEDEP}]
-# net-libs/libbar[ssl,${MULTILIB_USEDEP}]"
-# @CODE
-
-# @ECLASS-VARIABLE: MULTILIB_ABI_FLAG
-# @OUTPUT_VARIABLE
-# @DESCRIPTION:
-# The complete ABI name. Resembles the USE flag name.
-#
-# This is set within multilib_foreach_abi(),
-# multilib_parallel_foreach_abi() and multilib-minimal sub-phase
-# functions.
-#
-# It may be null (empty) when the build is done on ABI not controlled
-# by a USE flag (e.g. on non-multilib arch or when using multilib
-# portage). The build will always be done for a single ABI then.

-# @DEFAULT_UNSET
-# @DESCRIPTION:
-# A list of headers to wrap for multilib support. The listed headers

-# is not supported.
-#
-# Please note that header wrapping is *discouraged*. It is preferred to
-# install all headers in a subdirectory of libdir and use pkg-config to
-# locate the headers. Some C preprocessors will not work with wrapped
-# headers.
-#
-# Example:
-# @CODE
-# MULTILIB_WRAPPED_HEADERS=(
-# /usr/include/foobar/config.h
-# )
-# @CODE
-
-# @ECLASS-VARIABLE: MULTILIB_CHOST_TOOLS
-# @DEFAULT_UNSET
-# @DESCRIPTION:
-# A list of tool executables to preserve for each multilib ABI.
-# The listed executables will be renamed to ${CHOST}-${basename},
-# and the native variant will be symlinked to the generic name.
-#
-# This variable has to be a bash array. Paths shall be relative to
-# installation root (${ED}), and name regular files or symbolic
-# links to regular files. Recursive wrapping is not supported.
-#
-# If symbolic link is passed, both symlink path and symlink target
-# will be changed. As a result, the symlink target is expected
-# to be wrapped as well (either by listing in MULTILIB_CHOST_TOOLS
-# or externally).
-#
-# Please note that tool wrapping is *discouraged*. It is preferred to
-# install pkg-config files for each ABI, and require reverse
-# dependencies to use that.
-#
-# Packages that search for tools properly (e.g. using AC_PATH_TOOL
-# macro) will find the wrapper executables automatically. Other packages
-# will need explicit override of tool paths.

-# @CODE
-# MULTILIB_CHOST_TOOLS=(

-#
-# The files to be wrapped are specified using separate variables,

-# between the successive calls to multilib_prepare_wrappers

+#
+# This variable is intended for use in prebuilt multilib packages that

+#
+# The value of MULTILIB_COMPAT determines the value of IUSE. If set, it
+# also enables REQUIRED_USE constraints.

-# This function handles the basics of setting the SRC_URI for a gcc ebuild.
-# To use, set SRC_URI with:
-#
-# SRC_URI="$(get_gcc_src_uri)"
-#
-# Other than the variables normally set by portage, this function's behavior
-# can be altered by setting the following:
-#
-# SNAPSHOT
-# If set, this variable signals that we should be using a snapshot of
-# gcc. It is expected to be in the format "YYYY-MM-DD". Note that if
-# the ebuild has a _pre suffix, this variable is ignored and the
-# prerelease tarball is used instead.
-#
-# BRANCH_UPDATE
-# If set, this variable signals that we should be using the main
-# release tarball (determined by ebuild version) and applying a
-# CVS branch update patch against it. The location of this branch
-# update patch is assumed to be in ${GENTOO_TOOLCHAIN_BASE_URI}.
-# Just like with SNAPSHOT, this variable is ignored if the ebuild
-# has a _pre suffix.
-#
-# PATCH_VER
-# PATCH_GCC_VER
-# This should be set to the version of the gentoo patch tarball.
-# The resulting filename of this tarball will be:
-# gcc-${PATCH_GCC_VER:-${GCC_RELEASE_VER}}-patches-${PATCH_VER}.tar.bz2
-#
-# PIE_VER
-# PIE_GCC_VER
-# These variables control patching in various updates for the logic
-# controlling Position Independant Executables. PIE_VER is expected
-# to be the version of this patch, and PIE_GCC_VER the gcc version of
-# the patch:
-# An example:
-# PIE_VER="8.7.6.5"
-# PIE_GCC_VER="3.4.0"
-# The resulting filename of this tarball will be:
-# gcc-${PIE_GCC_VER:-${GCC_RELEASE_VER}}-piepatches-v${PIE_VER}.tar.bz2
-#
-# SPECS_VER
-# SPECS_GCC_VER
-# This is for the minispecs files included in the hardened gcc-4.x
-# The specs files for hardenedno*, vanilla and for building the "specs" file.
-# SPECS_VER is expected to be the version of this patch, SPECS_GCC_VER
-# the gcc version of the patch.
-# An example:
-# SPECS_VER="8.7.6.5"
-# SPECS_GCC_VER="3.4.0"
-# The resulting filename of this tarball will be:
-# gcc-${SPECS_GCC_VER:-${GCC_RELEASE_VER}}-specs-${SPECS_VER}.tar.bz2
-#
-# HTB_VER
-# HTB_GCC_VER
-# These variables control whether or not an ebuild supports Herman
-# ten Brugge's bounds-checking patches. If you want to use a patch
-# for an older gcc version with a new gcc, make sure you set
-# HTB_GCC_VER to that version of gcc.
-#
-# CYGWINPORTS_GITREV
-# If set, this variable signals that we should apply additional patches
-# maintained by upstream Cygwin developers at github/cygwinports/gcc,
-# using the specified git commit id there. The list of patches to
-# apply is extracted from gcc.cygport, maintained there as well.
-# This is done for compilers running on Cygwin, not for cross compilers

-# See bugs:
-# https://gcc.gnu.org/PR85663 (libsanitizer on mips)
-# https://bugs.gentoo.org/661252 (libvtv on powerpc64)
-#
-# Thus safer way to enable/disable the feature is to rely on implicit
-# enabled-by-default state:
-# econf $(usex foo '' --disable-foo)

+#
+# Other than the variables normally set by portage, this function's behavior
+# can be altered by setting the following:
+#
+# SNAPSHOT
+# If set, this variable signals that we should be using a snapshot of
+# gcc. It is expected to be in the format "YYYY-MM-DD". Note that if
+# the ebuild has a _pre suffix, this variable is ignored and the
+# prerelease tarball is used instead.
+#
+# BRANCH_UPDATE
+# If set, this variable signals that we should be using the main
+# release tarball (determined by ebuild version) and applying a
+# CVS branch update patch against it. The location of this branch
+# update patch is assumed to be in ${GENTOO_TOOLCHAIN_BASE_URI}.
+# Just like with SNAPSHOT, this variable is ignored if the ebuild
+# has a _pre suffix.
+#
+# PATCH_VER
+# PATCH_GCC_VER
+# This should be set to the version of the gentoo patch tarball.
+# The resulting filename of this tarball will be:
+# gcc-${PATCH_GCC_VER:-${GCC_RELEASE_VER}}-patches-${PATCH_VER}.tar.bz2
+#
+# PIE_VER
+# PIE_GCC_VER
+# These variables control patching in various updates for the logic
+# controlling Position Independant Executables. PIE_VER is expected
+# to be the version of this patch, and PIE_GCC_VER the gcc version of
+# the patch:
+# An example:
+# PIE_VER="8.7.6.5"
+# PIE_GCC_VER="3.4.0"
+# The resulting filename of this tarball will be:
+# gcc-${PIE_GCC_VER:-${GCC_RELEASE_VER}}-piepatches-v${PIE_VER}.tar.bz2
+#
+# SPECS_VER
+# SPECS_GCC_VER
+# This is for the minispecs files included in the hardened gcc-4.x
+# The specs files for hardenedno*, vanilla and for building the "specs" file.
+# SPECS_VER is expected to be the version of this patch, SPECS_GCC_VER
+# the gcc version of the patch.
+# An example:
+# SPECS_VER="8.7.6.5"
+# SPECS_GCC_VER="3.4.0"
+# The resulting filename of this tarball will be:
+# gcc-${SPECS_GCC_VER:-${GCC_RELEASE_VER}}-specs-${SPECS_VER}.tar.bz2
+#
+# HTB_VER
+# HTB_GCC_VER
+# These variables control whether or not an ebuild supports Herman
+# ten Brugge's bounds-checking patches. If you want to use a patch
+# for an older gcc version with a new gcc, make sure you set
+# HTB_GCC_VER to that version of gcc.
+#
+# CYGWINPORTS_GITREV
+# If set, this variable signals that we should apply additional patches
+# maintained by upstream Cygwin developers at github/cygwinports/gcc,
+# using the specified git commit id there. The list of patches to
+# apply is extracted from gcc.cygport, maintained there as well.
+# This is done for compilers running on Cygwin, not for cross compilers

+# Note [implicitly enabled flags]
+# -------------------------------
+# Usually configure-based packages handle explicit feature requests
+# like
+# ./configure --enable-foo
+# as explicit request to check for support of 'foo' and bail out at
+# configure time.
+#
+# GCC does not follow this pattern and instead overrides autodetection
+# of the feature and enables it unconditionally.
+# See bugs:
+# https://gcc.gnu.org/PR85663 (libsanitizer on mips)
+# https://bugs.gentoo.org/661252 (libvtv on powerpc64)
+#
+# Thus safer way to enable/disable the feature is to rely on implicit
+# enabled-by-default state:
+# econf $(usex foo '' --disable-foo)
