+  This file defines a family of macros
+
+       STAP_PROBEn(op1, ..., opn)
+
+  that emit a nop into the instruction stream, and some data into an auxiliary
+  note section.  The data in the note section describes the operands, in terms
+  of size and location.  Each location is encoded as assembler operand string.
+  Consumer tools such as gdb or systemtap insert breakpoints on top of
+  the nop, and decode the location operand-strings, like an assembler,
+  to find the values being passed.
+
+  The operand strings are selected by the compiler for each operand.
+  They are constrained by gcc inline-assembler codes.  The default is:
+
+  #define STAP_SDT_ARG_CONSTRAINT nor
+
+  This is a good default if the operands tend to be integral and
+  moderate in number (smaller than number of registers).  In other
+  cases, the compiler may report "'asm' requires impossible reload" or
+  similar.  In this case, consider simplifying the macro call (fewer
+  and simpler operands), reduce optimization, or override the default
+  constraints string via:
+
+  #define STAP_SDT_ARG_CONSTRAINT g
+  #include <sys/sdt.h>

+/* These macros are for use in asm statements.  You must compile
+   with -std=gnu99 or -std=c99 to use the STAP_PROBE_ASM macro.
+
+   The STAP_PROBE_ASM macro generates a quoted string to be used in the
+   template portion of the asm statement, concatenated with strings that
+   contain the actual assembly code around the probe site.
+
+   For example:
+
+	asm ("before\n"
+	     STAP_PROBE_ASM(provider, fooprobe, %eax 4(%esi))
+	     "after");
+
+   emits the assembly code for "before\nafter", with a probe in between.
+   The probe arguments are the %eax register, and the value of the memory
+   word located 4 bytes past the address in the %esi register.  Note that
+   because this is a simple asm, not a GNU C extended asm statement, these
+   % characters do not need to be doubled to generate literal %reg names.
+
+   In a GNU C extended asm statement, the probe arguments can be specified
+   using the macro STAP_PROBE_ASM_TEMPLATE(n) for n arguments.  The paired
+   macro STAP_PROBE_ASM_OPERANDS gives the C values of these probe arguments,
+   and appears in the input operand list of the asm statement.  For example:
+
+	asm ("someinsn %0,%1\n" // %0 is output operand, %1 is input operand
+	     STAP_PROBE_ASM(provider, fooprobe, STAP_PROBE_ASM_TEMPLATE(3))
+	     "otherinsn %[namedarg]"
+	     : "r" (outvar)
+	     : "g" (some_value), [namedarg] "i" (1234),
+	       STAP_PROBE_ASM_OPERANDS(3, some_value, some_ptr->field, 1234));
+
+    This is just like writing:
+
+	STAP_PROBE3(provider, fooprobe, some_value, some_ptr->field, 1234));
+
+    but the probe site is right between "someinsn" and "otherinsn".
+
+    The probe arguments in STAP_PROBE_ASM can be given as assembly
+    operands instead, even inside a GNU C extended asm statement.
+    Note that these can use operand templates like %0 or %[name],
+    and likewise they must write %%reg for a literal operand of %reg.  */
