* Continue to closely monitor GCC trunk validations
* Neon intrinsics tests
* Off Thursday/Friday
Short week, Labor day (2/10)
== Issues ==
* None
== Progress ==

o LP #1307197 : gcc-4.9 miscompiles linux kernel zlib for armv3
- This an LRA issue for architectures < armv4 withi movhi
- Investigation ongoing
o LP #1169164 : including signal.h exposes various PSR_MODE #defines
- The proposed patch fix the issue
- Still need some validation before upstream submission
* Test new backport workflow and Cbuild2 (2/10)
- Some troubles to access the build farm.
* Misc:
o Cbuildv1 baby-sitting (1/10)
o Various meetings (1/10).
== Next ==
- Two days off
- FSF branch merge + backports
== Issues ==
* None
== Progress ==
* May 1-2: Laybor day holiday
* Commit fcsel support patch for aarch64 @r209889.
* Tuning move-loop-invariants heuristics for -fira-loop-pressure:
- Record register pressure for each invariant other than a max for all.
- Take register pressure into account when selecting the best candidate.
== Plan ==
* Tuning move-loop-invariants heuristics
* Ping pending patches.
== Planned leaves ==
* June 2.

I have removed the "zlib" folder from "gcc-linaro-4.8-2014.03.tar.xz" tarball, the compiler is also using zlib-1.2.5 statically linked, and thats permit compile the Linaro toolchain.

Hello,
I have a problem building gcc-linaro-arm-linux-gnueabihf
toolchain for my x86_64 system. I download crosstool-ng (v1.13) and
toolchain source code (4.8-2014.03) from
http://releases.linaro.org/14.03/components/toolchain/binaries. I use
the example configuration linaro-arm-linux-gnueabihf (obtained from
ct-ng list-samples) and modify some entries using menuconfig option,
like the local tarballs directory (pointing to downloaded toolchains
source code directory) and the prefix directory (custom directory output).
This is the problem during the execution of "ct-ng build" command:

Some idea of what's the problem?
