Hi everyone, |
| 2 |
|
| 3 |
Regarding blockers against bug #461954 "(gcc-4.8) GCC 4.8 porting" and |
| 4 |
bug #516152 "(gcc-4.8-stable) sys-devel/gcc-4.8.? stabilization" here is |
| 5 |
the current situation: |
| 6 |
|
| 7 |
bug #516548 - (PR61538) broken atomic on MIPS R10000 |
| 8 |
-> As far as I can tell, this only effects R10000. It does not effect |
| 9 |
the fulong or longson (lemote netbooks), nor some other router boards i |
| 10 |
have. |
| 11 |
|
| 12 |
bug #503838 - (PR60465) sys-libs/glibc: building w/gcc-4.8 crashes early |
| 13 |
on ia64 |
| 14 |
-> This effects only ia64. |
| 15 |
|
| 16 |
bug #500064 - app-emulation/virtualbox-4.3.6 fails to build with gcc |
| 17 |
4.8.x in bundled iPXE |
| 18 |
-> Poly-C wants to stabilize these along side gcc-4.8. |
| 19 |
|
| 20 |
bug #465268 - dev-embedded/msp430-gcc-4.6.3_p20120406 with gcc-4.8.0 |
| 21 |
-> This is working with gcc-4.9 and doesn't need to hold up 4.8. |
| 22 |
|
| 23 |
bug 458706 - PaX: Max. per-task virtual memory too small for llvm asan |
| 24 |
and gcc-4.8 asan |
| 25 |
-> AddressSanitizer doesn't work with a PaX hardened kernel. Nor does it |
| 26 |
work on several arches nor on musl. vapier has done some masking here. |
| 27 |
|
| 28 |
bug 513386 - net-libs/webkit-gtk-2.4.3 - ./.libs/libwebkitgtk-3.0.so: |
| 29 |
undefined reference to `_ZNSt6chrono12steady_clock3nowEv@GLIBCXX_3.4.17' |
| 30 |
-> This is a problem. It relates to abi mismatching with libstdc++. |
| 31 |
The bug details how you can hit it in gentoo. Martin von Gagern pushed |
| 32 |
the issue upstream and pretty much got the answer "we're on our own" So |
| 33 |
we'll have to deal with this as we go forward. |
| 34 |
Seehttps://gcc.gnu.org/bugzilla/show_bug.cgi?id=61758 |
| 35 |
|
| 36 |
So except for some minor arch issue and bug 513386, which we're going to |
| 37 |
have to deal with for a while, gcc-4.8.3 looks good. I went ahead and |
| 38 |
stabilized it on ppc and ppc64. Its also stable on arm and hppa. I |
| 39 |
don't want to speak for any other arch teams, but it may be time. |
