Hi all,
We are using Linaro 13.03 toolchain(
gcc-linaro-arm-linux-gnueabihf-4.7-2013.03-20130313_linux We are trying to
execute a simple test code to check whether ARM assembly code executes on
board or not. Execution is on Arndale Board. Every time We include assembly
function, We get segmentation fault. Kindly check if I We are missing any
arm related flags in makefile.
We have attached the ‘helloworld’ test code and makefile.
Regards,
Vishwa
Is that supposed to be possible? When I add --disable-multilib to the
configure options, the build fails on the install, because it hasn't built
any of src/gcc-linaro-4.8-2014.02/libgcc:
/bin/sh ../../../../src/gcc-linaro-4.8-2014.02/libgcc/../mkinstalldirs
/home/ubuntu/work483/build/sysroot/home/ubuntu/opt/cross-gcc-linaro/lib/gcc/arm-linux-gnueabi/4.8.3
/usr/bin/install -c -m 644 libgcc_eh.a
/home/ubuntu/work483/build/sysroot/home/ubuntu/opt/cross-gcc-linaro/lib/gcc/arm-linux-gnueabi/4.8.3/
/usr/bin/install: cannot stat `libgcc_eh.a': No such file or directory
make[3]: *** [install-shared] Error 1
make[3]: Leaving directory
`/home/ubuntu/work483/build/gcc/arm-linux-gnueabi/libgcc'
make[2]: *** [install-target-libgcc] Error 2
make[2]: Leaving directory `/home/ubuntu/work483/build/gcc'
make[1]: *** [install] Error 2
make[1]: Leaving directory `/home/ubuntu/work483/build/gcc'
make: *** [stamp/gcc-install] Error 2
I don't want or need multilib, so I'd rather build the toolchain without
it, but before I try to make that happen, I wanted to make sure it's
supposed to be able to get built correctly that way.
Thanks,
Diane
== Progress ==
* IAS (TCWG-377)
- Long discussions about magic in inline asm
- Bottomline is: we're still validating anyway
* AArch64 (TCWG-387)
- Making it build with CMake, discarding some tests
- Similar changes to the test-suite
- All green except sphereflake
* Buildbots
- Investigating one failure on test-suite due
to register allocator changes
- Will continue this during or after Connect
* Background
- Connect preparations
- EuroLLVM 14 sync call, paper discussions
- Researching some kernel C/ASM syntax
- Studying __builtin_constant_p usage
- Patch reviews, etc.
* Time
- CARD-862 8/10
- Others 2/10
== Plan ==
* Connect
(slightly delayed)
== Progress ==
* 3 day week (annual leave Thursday and Friday)
* QEMU ARMv8 CRC instructions (4/10, TCWG-52)
* Slides for Connect (1/10)
* Further work on longjmp/setjmp Systemtap probes on ARM (1/10, TCWG-378)
== Issues ==
* None
== Plan ==
* Complete QEMU CRC instruction work
* Preparation for Connect

* CCMP for AARCH64.
- Design cases to cover most conditional compare combinations.
- Set up qemu environment and run regression tests. And fix all the new FAILs.
* Respawn 2014.01-01 baremental toolchains by setting
CT_TARGET_LDFLAGS=" --specs=rdimon.specs "
* Rebuild arm-linux-gnueabi toolchain and ran spec2k. But can not
reproduce the regression about Linaro 4.8 based on 2014.01 release.
== Plans ==
* Send out the CCMP patches for community review.
== Progress ==
