+# GCC does not follow this pattern and instead overrides autodetection

-# This function handles the basics of setting the SRC_URI for a gcc ebuild.

-# 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.

-# -------------------------------
-# Usually configure-based packages handle explicit feature requests

-# ./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

-# 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)

toolchain.eclass: import eclass with proposed ::gentoo changes (musl patchset)
Introduce a MUSL_VER patch variable and apply a patchset like we used to
for uclibc. This is in preparation for moving GCC from ::musl to
::gentoo.
The patchset has a nocross/ dir for patches which must
be applied only for native builds.
The patches were/are identical for each version in ::musl
which makes life easier:
```
musl/
musl/gcc-pure64.patch
musl/posix_memalign.patch
musl/nocross/
musl/nocross/gcc-6.1-musl-libssp.patch
musl/cpu_indicator.patch
```

+# This is for the minispecs files included in the hardened gcc-4.x

+# 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)

-# This function handles the basics of setting the SRC_URI for a gcc ebuild.
-# To use, set SRC_URI with:
-#
-# SRC_URI="$(get_gcc_src_uri)"
-#
-# Other than the variables normally set by portage, this function's behavior
-# can be altered by setting the following:
-#
-# GCC_TARBALL_SRC_URI
-# Override link to main tarball into SRC_URI. Used by dev-lang/gnat-gpl
-# to provide gcc tarball snapshots. Patches are usually reused as-is.
-#
-# SNAPSHOT
-# If set, this variable signals that we should be using a snapshot of
-# gcc. It is expected to be in the format "YYYY-MM-DD". Note that if
-# the ebuild has a _pre suffix, this variable is ignored and the
-# prerelease tarball is used instead.
-#
-# PATCH_VER
-# PATCH_GCC_VER
-# This should be set to the version of the gentoo patch tarball.
-# The resulting filename of this tarball will be:
-# gcc-${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
-#
-# 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)
