Removing neon eliminates the vector floating point, which we do not want to do. The correct fix for this is probably in gcc. I'd rather not build lttng for beagleboard than change the tune default to DEFAULT_TUNE to "cortexa8". -- Darren Hart Intel Open Source Technology Center Yocto Project - Linux Kernel ^ permalink raw reply [flat|nested] 6+ messages in thread

Version of lttng-ust is 0.15. Initially I tried to do something with tcmode-default, setting lttng-ust similar to meta-xlib which also had a ICE issue. TARGET_CC_ARCH_arm_pn-mesa-xlib := "${@'${TARGET_CC_ARCH}'.replace('armv7-a','armv5')}" That caused the compiler to complain about a mode issue, probably due to mixing of tune parameters: | arm-poky-linux-gnueabi-libtool: compile: ccache arm-poky-linux-gnueabi-gcc -march=armv5 -fno-tree-vectorize -mthumb-interwork -mfloat-abi=softfp -mfpu=neon -mtune=cortex-a8 --sysroot=/vol/1/sgw/autobuilder/yab/yocto-slave/external/build/build/tmp/sysroots/beagleboard -DHAVE_CONFIG_H -I. -I.. -I../include/ust -I../include -I../libustcomm -DUST_COMPONENT=libust -fno-strict-aliasing -Wall -pipe -g -feliminate-unused-debug-types -MT libust_la-marker-control.lo -MD -MP -MF .deps/libust_la-marker-control.Tpo -c marker-control.c -o libust_la-marker-control.o >/dev/null 2>&1 | mv -f .deps/libust_la-tracercore.Tpo .deps/libust_la-tracercore.Plo | {standard input}: Assembler messages: | {standard input}:190: Error: selected processor does not support ARM mode `dmb' Yes, we are trying to solve Compiler issue, when I first started working on the last week there was not a compiler bug filed, but now there seems to be one! http://gcc.gnu.org/bugzilla/show_bug.cgi?id=43137 Which looks like it is resolved also!
