* toolchain-glibc.eclass: drop support for 'BRANCH_UPDATE'Sergei Trofimovich2019-10-191-12/+0
| | | | | | | BRANCH_UPDATE needs explicit tarball creation. Live ebuilds suit better for tracking upstream development. Signed-off-by: Sergei Trofimovich <slyfox@gentoo.org>

* toolchain-glibc.eclass: drop prepallstrip, bug #587296Sergei Trofimovich2019-09-251-18/+0
| | | | | | | | | | | This effectively reverts https://bugs.gentoo.org/46186. Modern gdb can inspect threads without debugging symbols in libpthread/libthread_db.

* toolchain-glibc.eclass: ignore USE=headers-only for native case, bug #677474Sergei Trofimovich2019-02-071-1/+1

* toolchain-glibc.eclass: avoid using KV_to_int and get_KVSergei Trofimovich2019-01-271-4/+50
| | | | | | | | | | | | | | | 'KV_to_int' and 'get_KV' are portage internals. This change pulls in implementation of 'KV_to_int' and 'get_KV' as-is with a rename: KV_to_int -> tc_glibc_KV_to_int get_KV -> tc_glibc_get_KV (small API change) Reported-by: Brian Harring Reported-by: Michał Górny Bug: https://bugs.gentoo.org/384041 Closes: https://bugs.gentoo.org/587320 Signed-off-by: Sergei Trofimovich <slyfox@gentoo.org>
* toolchain-glibc.eclass: drop PIE ewarnSergei Trofimovich2018-10-241-3/+0

* toolchain-glibc.eclass: remove git logicMarty E. Plummer2018-06-081-10/+1
| | | | | | | The git logic is handled in the live ebuild directly, and the only use of this eclass is in non-live ebuilds. In fact, the two newest non-live ebuilds do not make use of this eclass at all, and as far as I can see nowhere in the history of this file does it inherit git-2 at all.
* toolchain-glibc.eclass: fix glibc-headers bootstrap on non-multilib hostSergei Trofimovich2018-03-301-0/+8
| | | | | | | | | | | | | | | | | | | | | | | The error is found by wm_ attempting to build a cross-compiler CHOST=powerpc-unknown-linux-gnu CTARGET=mips64-unknown-linux-gnu Boostrap failed on glibc-headers (./configure phase) as: configure:2623: powerpc-unknown-linux-gnu-gcc -mabi=n32 -c -O1 -pipe -U_FORTIFY_SOURCE conftest.c >&5 powerpc-unknown-linux-gnu-gcc: error: unrecognized command line option '-mabi=n32'; did you mean '-mabi=d32'? Note how target's ABI is mexed into host's compiler flags. The error above happens on every host=non-multilib target=multilib combination. I've reproduced it on: CHOST=i686-pc-linux-gnu CTARGET=mips64-unknown-linux-gnu The fix is not to inject target's CFLAGS ABI into CC for USE=headers-only bootstrap step as we don't have cross-compiler yet. Tested by successfully bootstrapping cross-compiler on CHOST=i686-pc-linux-gnu CTARGET=mips64-unknown-linux-gnu Signed-off-by: Sergei Trofimovich <slyfox@gentoo.org>

* toolchain-glibc.eclass: Migrate CROSSCOMPILE_OPTS=headers-only -> ↵Sergei Trofimovich2018-01-071-1/+1
| | | | | | | | | | | | | | | | | | | USE=headers-only CROSSCOMPILE_OPTS is a USE_EXPAND of a single item: headers-only. Convert it to a global USE flag instead. Mechanical ebuild rename done as: $ sed -e 's@crosscompile_opts_headers-only@headers-only@g' \ -i $(git grep -l headers-only) 'headers-only' flag is used by crossdev to bootstrap stage1 compiler before libc is available. crossdev switched to USE=headers-only in =sys-devel/crossdev-20171230.

* sys-libs/glibc: enable IFUNC support only on whitelisted ARCHes, bug #641216Sergei Trofimovich2017-12-201-0/+11
| | | | | | | | | | | | | | | | We explicitly disable IFUNC support on the following targets: alpha/hppa/ia64/mips/m68k/nios2/riscv/sh to workaround weak IFUNC detection on binutils/glibc side. Otherwise at least on ia64 glibc generates IFUNC entries against compat librt.so.1 symbols (to redirect them back to libc.so.6) but linker does not produce correct relocations. As a result all IFUNC-backed functions don't work.

* toolchain-glibc.eclass: Replace evar_* with local variablesMichał Górny2017-04-141-3/+1
| | | | | | Use local variable to limit the scope of ABI variable override. This is a builtin bash solution that is reliable and simple, unlike the complex evar_* logic that unnecessarily pollutes global variables.
