Dear Alexey,
Yes I am sure that the llvm, clang and compiler-rt are synced to the same
version. I downloaded them all from git
http://llvm.org/docs/GettingStarted.html#git-mirror
I think I need compiler-rt for my project but I'll verify it again to see
if I can proceed without it.
You are correct that compiler-rt is compiled with the just built clang. The
complete command that gives an error while compiler-rt compilation is:
/home/pranav/smack-project/llvm/build/Release+Asserts/bin/clang -fPIC -Wall
-Werror -O3 -fomit-frame-pointer -m64
--sysroot=/home/pranav/smack-project/llvm/src/projects/compiler-rt/SDKs/linux
-c -o
/home/pranav/smack-project/llvm/build/tools/clang/runtime/compiler-rt/clang_linux/full-x86_64/x86_64/SubDir.lib/enable_execute_stack.o
/home/pranav/smack-project/llvm/src/projects/compiler-rt/lib/enable_execute_stack.c
/home/pranav/smack-project/llvm/src/projects/compiler-rt/lib/enable_execute_stack.c:53:29:
error: cast to 'unsigned char *' from smaller integer type 'unsigned
int'
[-Werror,-Wint-to-pointer-cast]
unsigned char* startPage = (unsigned char*)(p & pageAlignMask);
Thanks

yes I think that is correct. I wrote a simple program to print if sizeof(uintptr_t) != sizeof(unsigned char *) and when I compile with gcc -m64 and execute it on a 64-bit host (that is different from the 32-bit laptop on which I originally compiled the program), it says the sizes are not equal.
