Comment #6 on issue 836 by [email protected]: armv5tel compilation error
in macro-assembler-arm.cc "For thumb inter-working we require an
architecture which supports blx"
http://code.google.com/p/v8/issues/detail?id=836
When I change v8/SConstruct, it does not seem to change the flags during
compilation.
136 'gcc': {
137 'all': {
138 'CCFLAGS':
['$DIALECTFLAGS', '$WARNINGFLAGS','-march=armv6'],
139 'CXXFLAGS':
['$CCFLAGS', '-fno-rtti', '-fno-exceptions', '-march=armv6'],
140 },
I'm using berkelium and the build finishes as follows:
arm-linux-gnueabi-g++ '-DENABLE_LOGGING_AND_PROFILING' '-DENABLE_DEBUGGER_SUPPORT' '-DENABLE_VMSTATE_TRACKING' '-DV8_TARGET_ARCH_ARM' '-DNO_TCMALLOC' '-DNO_HEAPCHECKER' '-DDISABLE_NACL' '-DCHROMIUM_BUILD' '-DENABLE_REMOTING=1' '-DENABLE_GPU=1' '-DENABLE_EGLIMAGE=1' '-DNDEBUG' '-DNVALGRIND' '-DDYNAMIC_ANNOTATIONS_ENABLED=0'

I've also tried to delete the mk files generated by gyp in v8/tools/gyp,
but they generated again without the correct flags.
This is my environment:
