== This week ==
* TCWG-619 (8/10)
PR65858
- workaround: add explicit casts in the file cld_generated_cjk_uni_prop_80.cc
- created reduced test case: http://pastebin.com/WJvKRjn2
- commit r222249 introduced the issue
- patch submitted upstream:
https://gcc.gnu.org/ml/gcc-patches/2015-04/msg02063.html
- Paolo Carlini pointed out it doesn't work with -w option, instead of testing
on warn_narrowing flag, he modified it to check on pedwarn()'s return
value, which
covers up for both -Wno-narrowing and -w, and committed with
this modification (r222700).
PR65837
- patch to lto-wrapper rejected.
- Another hack to pass driver's argv to lto-wrapper via another
environment variable
COLLECT_GCC_OPTIONS_DRIVER rejected by Richard.
- Ramana and Richard pointed out the proper fix would be to handle
target attributes in ARM backend.
- I could try extending Christian Bruel's target attribute patches for
fpu options
after they're checked in which would then fix the PR.
chromium LTO build
- Many instances of same error message during LINK chrome:
chrome.ltrans0.s:18399164: Error: Thumb2 branch out of range
chrome.ltrans0.s:9671243: Error: branch out of range
works fine for non-lto.
A similar issue, occurred for v8 LTO build - PR65778, but
it was marked resolved invalid.
- chromium builds with LTO for chrome component.
- ld.bfd segfault while building chromium with LTO not reproducible with master.
- non-LTO build undefined reference to libattr1 functions not reproducible with
ld.bfd master. This probably was sysroot/libc issue than issue with ld.bfd.
* PR49551 (2/10)
- reverting r221297 reproduces the ICE
- tried to fix with following patch:
http://pastebin.com/knuWeY0C
- fixes the ICE but following regressions observed on arm-linux-gnueabihf:
http://pastebin.com/E1zLtq8s
== Issues ==
- Can't login to cards.linaro.org (was able to before).
I get error - "You do not have permission to login".
== Next Week ==
- Investigate testsuite failures for PR49551
- Selectively enable LTO on components in chromium.
- exams preparation
