libstdc++6 built from gcc-4.7 missing some symbols for arm-linux-gnueabi

by Matthias Klose

asking for some help about debian #697521 and lp: #1096619. looking at the config.log files for armel/armhf I don't see any differences. I assume it's a difference in the cpu configuration (armv4/v5 vs. armv7) not soft/hard-float. any pointers?

by naveen yadav

Dear All, Is it possible to disable STB_GNU_UNIQUE(http://cygwin.com/ml/binutils/2011-10/msg00276.html) We need to rebuild the toolchain/ or is there any option at compile time to fix. Kind regards

int64_t definition conflict on Aarch64

by Riku Voipio

Hi, The following code fails to build with OE Aarch64 toolchain with current kernel headers. While ugly, the code is a reduced testcase from fuse build failure ( https://bugs.launchpad.net/linaro-oe/+bug/1087757 ) and the same fuse code compiles on all other architectures. Before I send a workaround for upstream, I'd like to know how we can end up with different definitions for int64_t when that happens on no other architectures - something wrong with the generic kernel headers? Testcase: #include <sys/types.h> #define __s64 int64_t #include <signal.h> int main(int argc, char **argv) { int64_t x=4; return x; } Failure: /data/oe/build/tmp-eglibc/sysroots/x86_64-linux/usr/bin/aarch64-oe-linux/aarch64-oe-linux-gcc -save-temps --sysroot=/data/oe/build/tmp-eglibc/sysroots/genericarmv8 -o test test.c In file included from /data/oe/build/tmp-eglibc/sysroots/genericarmv8/usr/include/asm-generic/types.h:7:0, from /data/oe/build/tmp-eglibc/sysroots/genericarmv8/usr/include/asm/types.h:1, from /data/oe/build/tmp-eglibc/sysroots/genericarmv8/usr/include/linux/types.h:4, from /data/oe/build/tmp-eglibc/sysroots/genericarmv8/usr/include/asm/sigcontext.h:19, from /data/oe/build/tmp-eglibc/sysroots/genericarmv8/usr/include/bits/sigcontext.h:27, from /data/oe/build/tmp-eglibc/sysroots/genericarmv8/usr/include/signal.h:338, from test.c:4: /data/oe/build/tmp-eglibc/sysroots/genericarmv8/usr/include/asm-generic/int-ll64.h:29:44: error: conflicting types for 'int64_t' In file included from test.c:2:0: /data/oe/build/tmp-eglibc/sysroots/genericarmv8/usr/include/sys/types.h:197:13: note: previous declaration of 'int64_t' was here

[Activity] Week 52

by Zhenqiang Chen

Summary: * Follow-up shrink-up and branch cost related work. * Investigate "MSR FPEXC, r2" assemble fail issues. Details: 1. RM toolchain related work. 2. Investigate "MSR FPEXC, r2" assemble fail issues. * According to Reference Manual, should use VMSR/VMRS to access FPEXC register other than MSR/MRS. * Binutils 2.23.1 or later had enhanced VMRS/VMSR to accept FPEXC register. 3. Rebase and test the shrink-wrap patches. 4. Read codes about impact of branch-cost. Plan: * Follow up the shrink-wrap and branch cost related work. Planed leaves: * Jan. 1-3, 2013 Best Regards! -Zhenqiang
