A lot of -Wcast-qual warning when bootstrapping clang+compiler-rt on Mac.

Hi,

I’ve noticed a lot of -Wcast-qual warnings in tsan and sanitizer_common when bootstrapping clang with compiler-rt on Mac. Does anyone else see them?

Here are examples:

/Users/dybaboki/llvm/llvm-trunk/projects/compiler-rt/lib/sanitizer_common/sanitizer_procmaps_mac.cc:215:19: warning: cast from ‘const char *’ to ‘char *’ drops const qualifier [-Wcast-qual]
/Users/dybaboki/llvm/llvm-trunk/projects/compiler-rt/lib/tsan/rtl/tsan_interceptors_mac.cc:115:1: warning: cast from ‘volatile int *’ to ‘unsigned int *’ drops volatile qualifier [-Wcast-qual]
