-# 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
-#			with a Cygwin target.

-# 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)

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
```

+#
+#	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.

+#
+#	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.

+# 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)

-# 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
-#			with a Cygwin target.

-# 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)

+# 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)
