# 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 ${GENTOO_TOOLCHAIN_BASE_URI}.
|
|
# Just like with SNAPSHOT, this variable is ignored if the ebuild
|
|
# has a _pre suffix.
|
|
#
|
|
# PATCH_VER
|
|
# PATCH_GCC_VER
|
|
# This should be set to the version of the gentoo patch tarball.
|
|
# The resulting filename of this tarball will be:
|
|
# gcc-${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.

# SPECS_VER="8.7.6.5"
