+This folder contains list of symbols that should be excluded from the builtin
+libraries for Darwin. There are two reasons symbols are excluded:
+
+(1) They aren't supported on Darwin
+(2) They are contained within the OS on the minimum supported target
+
+The builtin libraries must contain all symbols not provided by the lowest
+supported target OS. Meaning if minimum deployment target is iOS 6, all builtins
+not included in the ios6-<arch>.txt files need to be included. The one catch is
+that this is per-architecture. Since iOS 6 doesn't support arm64, when supporting
+iOS 6, the minimum deployment target for arm64 binaries is iOS 7.

+/*
+ * This is the master file that defines all the data structure, signature,
+ * constant literals that are shared across profiling runtime library,
+ * compiler (instrumentation), and host tools (reader/writer). The entities
+ * defined in this file affect the profile runtime ABI, the raw profile format,
+ * or both.
+ *
+ * The file has two identical copies. The master copy lives in LLVM and
+ * the other one sits in compiler-rt/lib/profile directory. To make changes
+ * in this file, first modify the master copy and copy it over to compiler-rt.
+ * Testing of any change in this file can start only after the two copies are
+ * synced up.
+ *
+ * The first part of the file includes macros that defines types, names, and
+ * initializers for the member fields of the core data structures. The field
+ * declarations for one structure is enabled by defining the field activation
+ * macro associated with that structure. Only one field activation record
+ * can be defined at one time and the rest definitions will be filtered out by
+ * the preprocessor.
+ *
+ * Examples of how the template is used to instantiate structure definition:
+ * 1. To declare a structure:
+ *
+ * struct ProfData {
+ * #define INSTR_PROF_DATA(Type, LLVMType, Name, Initializer) \
+ * Type Name;
+ * #include "llvm/ProfileData/InstrProfData.inc"
+ * };
+ *
+ * 2. To construct LLVM type arrays for the struct type:
+ *
+ * Type *DataTypes[] = {
+ * #define INSTR_PROF_DATA(Type, LLVMType, Name, Initializer) \
+ * LLVMType,
+ * #include "llvm/ProfileData/InstrProfData.inc"
+ * };
+ *
+ * 4. To construct constant array for the initializers:
+ * #define INSTR_PROF_DATA(Type, LLVMType, Name, Initializer) \
+ * Initializer,
+ * Constant *ConstantVals[] = {
+ * #include "llvm/ProfileData/InstrProfData.inc"
+ * };
+ *
+ *
+ * The second part of the file includes definitions all other entities that
+ * are related to runtime ABI and format. When no field activation macro is
+ * defined, this file can be included to introduce the definitions.

//
-// 1) Protection via hardware segmentation on x32 architectures: the (safe)

+// segment would result in a segmentation fault.
//
-// 2) Protection via information hiding on 64 bit architectures: the location of
-// the safe stack can be randomized through secure mechanisms, and the leakage
-// of the stack pointer can be prevented. Currently, libc can leak the stack
-// pointer in several ways (e.g. in longjmp, signal handling, user-level context
-// switching related functions, etc.). These can be fixed in libc and in other
-// low-level libraries, by either eliminating the escaping/dumping of the stack
-// pointer (i.e., %rsp) when that's possible, or by using encryption/PTR_MANGLE
-// (XOR-ing the dumped stack pointer with another secret we control and protect
-// better). (This is already done for setjmp in glibc.) Furthermore, a static
-// machine code level verifier can be ran after code generation to make sure
-// that the stack pointer is never written to memory, or if it is, its written
-// on the safe stack.
+// 2) Protection via software fault isolation: memory writes that are not meant
+// to access the safe stack can be prevented from doing so through runtime
+// instrumentation. One way to do it is to allocate the safe stack(s) in the

+2. libt-no-instr1.so is not instrumented
+3. libt-no-instr2.so is compiled with instrumentation enabled, but the object file is built
+ with instrumentation turned off.
+
+After the libraries are built, the main program is then built with/without instrumentation and linked
