Hi Sam,
I just noticed (on a clean-enough rebuild :-) ) I'm getting a warning from
this on GCC 4.8:
../unittests/Support/ARMAttributeParser.cpp: In function ‘bool
testBuildAttr(unsigned int, unsigned int, unsigned int, unsigned int)’:
../unittests/Support/ARMAttributeParser.cpp:34:52: warning: cast from type
‘const char*’ to type ‘uint8_t* {aka unsigned char*}’ casts away qualifiers
[-Wcast-qual]
ArrayRef<uint8_t> Bytes((uint8_t*)OS.str().c_str(), OS.str().size());
Thanks,
Michael
