+#### has_pie ####
+# Returns true if the compiler by default or with current CFLAGS
+# builds position-independent code.
+#
+#### has_pic ####
+# Returns true if the compiler by default or with current CFLAGS
+# builds position-independent code.
+#
+#### has_ssp_all ####
+# Returns true if the compiler by default or with current CFLAGS
+# generates stack smash protections for all functions

+#			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
+#	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:
+#			gcc-${PIE_GCC_VER:-${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

+workaround for lame stack packing on i386 ...
+
+	- build gcc with -Os (crtfastmath.o to be specific)
+	- crtfastmath.o is installed into gcc libdir
+	- run gcc with -ffast-math and get crtfastmath.o linked in
+	- resulting compiled app segfaults due to init code in
+	  crtfastmath.o that has mis-aligned structure on stack
+
+http://bugs.gentoo.org/147020
+http://gcc.gnu.org/PR28621
+
+this is supposed to be fixed in current 4.1 branch, but i'm unable to get
+the fix to work so until i can figure out what i'm doing wrong, we'll use
+this workaround for now.

+	Modifications to glibc-2.4 to allow it to build with stack-protection
+	enabled throughout.
+
+	debug/Makefile: build stack_chk_fail_local -fno-stack-protector
+	  Leave stack_chk_fail alone, so checking __SSP__ will show whether
+	  compiler is rigged to build SSP, and hence that we want the modified
+	  handler (which will never trigger SSP because there are no function
+	  calls).
+
+	csu/Makefile, linuxthreads/Makefile, nptl/Makefile: inihibit SSP on
+	  crti/crtn (i.e. compilation of initfini)
+
+	elf/rtld-Rules: Add compilation rules for .oS targets (so that
+	  stack_chk_fail_local will build for rtld).
+
+	elf/Makefile: Add libc_nonshared.a to rtld build set so that
+	  stack_chk_fail_local can be found (and other modifications
+	  so that static objects are considered).
+
+	Makerules: add stack_chk_fail_local.oS to libc_pic.os (needed for
+	  SSP builds on x86 so that it can resolve __stack_chk_fail_local).
+	  Note this is a whole-archive link so adding libc_nonshared.a
+	  causes too much stuff to be included.

+### SRC_URI ###
+
+# This function handles the basics of setting the SRC_URI for a glibc ebuild.
+# To use, set SRC_URI with:
+#
+#	SRC_URI="$(get_glibc_src_uri)"
+#
+# Other than the variables normally set by portage, this function's behavior
+# can be altered by setting the following:
+#
+#	GENTOO_TOOLCHAIN_BASE_URI
+#			This sets the base URI for all gentoo-specific patch files. Note
+#			that this variable is only important for a brief period of time,
+#			before your source files get picked up by mirrors. However, it is
+#			still highly suggested that you keep files in this location
+#			available.
+#
+#	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 ${GENTOO_TOOLCHAIN_BASE_URI}.
+#			Just like with SNAPSHOT, this variable is ignored if the ebuild
+#			has a _pre suffix.
+#
+#	PATCH_VER
+#	PATCH_GLIBC_VER
+#			This should be set to the version of the gentoo patch tarball.
+#			The resulting filename of this tarball will be:
+#			glibc-${PATCH_GLIBC_VER:-${GLIBC_RELEASE_VER}}-patches-${PATCH_VER}.tar.bz2
+#
+#	GLIBC_MANPAGE_VERSION
+#	GLIBC_INFOPAGE_VERSION
+#			The version of glibc for which we will download pages. This will
+#			default to ${GLIBC_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.

+### SRC_URI ###
+
+# This function handles the basics of setting the SRC_URI for a glibc ebuild.
+# To use, set SRC_URI with:
+#
+#	SRC_URI="$(get_glibc_src_uri)"
+#
+# Other than the variables normally set by portage, this function's behavior
+# can be altered by setting the following:
+#
+#	GENTOO_TOOLCHAIN_BASE_URI
+#			This sets the base URI for all gentoo-specific patch files. Note
+#			that this variable is only important for a brief period of time,
+#			before your source files get picked up by mirrors. However, it is
+#			still highly suggested that you keep files in this location
+#			available.
+#
+#	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 ${GENTOO_TOOLCHAIN_BASE_URI}.
+#			Just like with SNAPSHOT, this variable is ignored if the ebuild
+#			has a _pre suffix.
+#
+#	PATCH_VER
+#	PATCH_GLIBC_VER
+#			This should be set to the version of the gentoo patch tarball.
+#			The resulting filename of this tarball will be:
+#			glibc-${PATCH_GLIBC_VER:-${GLIBC_RELEASE_VER}}-patches-${PATCH_VER}.tar.bz2
+#
+#	GLIBC_MANPAGE_VERSION
+#	GLIBC_INFOPAGE_VERSION
+#			The version of glibc for which we will download pages. This will
+#			default to ${GLIBC_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.

+NOTES
+=====
+
+Non-PIE support is a mess (well, strictly speaking it's broken)
+So far, crt{begin,end}.o are now correctly built no-PIE.
+However, libgcc.a/libgcc_eh.a, libc.a, libpthread.a, libieee.a, libgcov.a
+are built PIE.  This ok for linking PIEs, but rubbish for doing non-PIE
+links (i.e. vanilla).  Also crtfastmath.o is only built once (there's no
+crtfastmathS.o) - so we build it PIE.
+
+So, what to do?
+
+For vanilla compiles, we need the .a's built -nopie.
+For hardened compiles, we need the .a's built -fPIE - if they ever get used
+that way.  If we can convince ourselves that when building -fPIE the .so's
+are used, then we don't need PIE versions of these .a's.
+To do this, add '-nopie' to CFLAGS for libgcc.a in gcc/Makefile.in?
+
+For libc.a - we could treat hardened as a multilib system; with the normal no-PIE
+ABI and our PIE ABI - and get glibc to build itself two ways; one for vanilla and
+one for hardened.  Or, we could try to force all .a's to be built -nopie - this
+isn't easy, however, as you can't tell from normal compilation commands whether
+it's for a .a or for an executable.
+
+I think the multiple-ABI approach is easier.  We could then drop PIE from the
+compiler variants,  leaving just relro/now and ssp combinations, which don't change
+the ABI, and do the -fPIE thing in the compiler wrapper, when ABI is PIE.
+I'm thinking of doing MULTLIB_ABIS="x86 x86_pie" and defining
+CFLAGS_x86_pie="-fpie -pie"
+LDFLAGS_x86_pie="-fpie -pie"
+LIBDIR_x86="lib"
+LIBDIR_x86_pie="libpie"
+note; the gcc-config wrapper adds CFLAGS_x86_pie to the command line, but doesn't look at LDFLAGS_<abi>
+
+
+Upgrade path for Hardened Gentoo users from glibc-2.3*/gcc-3* to glibc-2.4+/gcc-4.1+
+====================================================================================
+
+Note; references to "hardened", "non-hardened" etc refer to the toolchain, not the
+kernel.
+
+
+Generic upgrade instructions
+----------------------------
+
+There are separate instructions depending on where you start.  Instruction set (2)
+should work in all cases, provided a vanilla compiler is set via gcc-config first.
+However the most common case will be (1) - which is why it's listed first :)
+
+
+1) HARDENED SYSTEMS with hardened gcc-3 and glibc-2.3
+   Going from an existing hardened system (gcc-3.4.6 & glibc-2.3.6 hardened)
+
+  .1) emerge --oneshot sys-libs/glibc
+      build the hardened version of glibc-2.4 (with the gcc-3 hardened compiler)
+
+  .2) emerge --oneshot sys-devel/gcc
+      build the hardened gcc-4.1.1 with the hardened gcc-3.4.6
+      
+  .3) emerge --oneshot sys-libs/glibc
+      rebuild the hardened version of glibc-2.4 (with the gcc-4 hardened compiler)
+
+
+2) NON-HARDENED SYSTEMS with gcc-4.1.1 and glibc-2.4 (no -hardened compiler available)
+   Going from non-hardened stage3 2006.1:
+   This starts from non-hardened gcc-4.1.1 and glibc-2.4
+
+  .1) Switch profile to the hardened profile
+      This means remaking the softlink /etc/make.conf to a hardened profile.
+	  Do not confuse this with selecting a hardened compiler with gcc-config (which
+	  you can't do anyway from the standard 2006.1 stage3).
+
+  .2) emerge --oneshot sys-libs/glibc
+      Build glibc with support for both gcc-3 and gcc-4 stack protectiona.
+
+  .3) USE="-hardened" emerge --oneshot sys-devel/gcc
+      Build gcc-4 non-hardened, but including split-specs so it can build
+	  hardened objects later.
+
+  .4) gcc-config to the (now available) hardened variant of the compiler.
+
+  .5) emerge --oneshot sys-libs/glibc
+      Build the hardened version of glibc-2.4 (with the gcc-4 hardened compiler)
+
+  .6) emerge --oneshot sys-devel/gcc
+      This will build gcc itself hardened (in particular, building the static libraries PIE)
+
+
+3) NON-HARDENED SYSTEMS with a -hardened gcc available
+
+  .1) gcc-config to the -hardened gcc
+
+  .2) emerge --oneshot sys-libs/glibc
+      Build glibc with support for both gcc-3 and gcc-4 stack protectiona.
+
+  .3) emerge --oneshot sys-devel/gcc
+      build the hardened gcc-4.1.1 with a hardened gcc
+
+  .4) emerge --oneshot sys-libs/glibc
+      rebuild the hardened version of glibc-2.4 (with the gcc-4 hardened compiler)
+
+
+Platform-specific notes
+-----------------------
+
+sparc
+For gcc-4 SSP to work, glibc must be 2.4 or higher.  Glibc-2.4 is nptl-only, so this means
+it's not available on 32-bit sparc (sparcv8).
+
+
+
+
+Toolchain mods for hardened gcc-4.x/glibc-2.4
+=============================================
+
+* glibc __stack_chk_fail implementation written so that it's ok when glibc built with SSP
+  Implement stderr & syslog messaging, SIGKILL and _exit to provide a secure termination
+  (the one supplied by glibc is for debug purposes only), and all via inline syscalls
+  avoiding any function calls (which would potentially invoke __stack_chk_fail).
+  Note; building glibc with ssp-all is causing too many problems at the moment, so for
+  now it's set to build without ssp.
+  Sorted out the PIE building better (replaces the filter-ldflags -pie with something
+  more sensible).
+  (done) Use SIG_ABRT instead of SIG_KILL - means doing the sigset stuff.
+  (done) Use INTERNAL_SYSCALL (check vsyscall page isn't user modifiable)
+
+* gcc minispecs for gcc-4.1.1 and gcc-3.4.6, from psm
+  Much simplified gcc patching for hardened compiler; use of minispecs to generate
+  the relevant specs files.  Involves a few changes in toolchain.eclass and
+  flag-o-matic.eclass.
+
+* Specs switching handled by the wrappers, rather than the gcc-specs-env patch
+  (app-admin/eselect-compiler only).  This gives us ccache reliability, as for
+  gcc itself the specs are specified on the command line as normal.
+  May not be a good idea - doing it gcc itself guarantees it'll happen even if
+  the wrappers aren't used (is that ever the case?).
+  Further investigation ongoing to manage filtering; considering doing this by
+  adjusting GCC_SPECS, although it may be better as a separate variable (perhaps
+  as part of COMPILER_FEATURES - see bug #128810)
+
+Still cooking
+
+* Look into -DFORTIFY_SOURCE=2, -msecure-plt for ppc
+
+
+Status summary:
+===============
+
+glibc ok (builds itself non-ssp)
+gcc ok (ish)
+   Needs distfile gcc-4.1.1-piepatches-v9.0.6.tar.bz2 from toolchain/distfiles
+   (or gcc-3.4.6-piepatches-v9.0.5.tar.bz2 for gcc-3.4.6)
