# 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 from ftp://sources.redhat.com/pub/gcc/snapshots/. 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:
# ${PN}-${PATCH_GCC_VER:-${GCC_RELEASE_VER}}-patches-${PATCH_VER}.tar.bz2
#
# PIE_VER
# PIE_GCC_VER
# obsoleted: PIE_CORE
# 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, PIE_GCC_VER the gcc version of
# the patch, and PIE_CORE (obsoleted) the actual filename 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:
# ${PN}-${PIE_GCC_VER:-${GCC_RELEASE_VER}}-piepatches-v${PIE_VER}.tar.bz2
# old syntax (do not define PIE_CORE anymore):
# PIE_CORE="gcc-3.4.0-piepatches-v${PIE_VER}.tar.bz2"
#
# PP_VER
# PP_GCC_VER
# obsoleted: PP_FVER
# These variables control patching in stack smashing protection
# support. They both control the version of ProPolice to download.
#
# PP_VER / PP_GCC_VER
# Used to roll our own custom tarballs of ssp.
# PP_FVER / PP_VER
# Used for mirroring ssp straight from IBM.
# PP_VER sets the version of the directory in which to find the
# patch, and PP_FVER sets the version of the patch itself. For
# example:
# PP_VER="3_4"
# PP_FVER="${PP_VER//_/.}-2"
# would download gcc3_4/protector-3.4-2.tar.gz
#
# 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.
#
# MAN_VER
# The version of gcc for which we will download manpages. This will
# default to ${GCC_RELEASE_VER}, but we may not want to pre-generate man pages
# for prerelease test ebuilds for example. This allows you to
# continue using pre-generated manpages from the last stable release.
# If set to "none", this will prevent the downloading of manpages,
# which is useful for individual library targets.
