+ that emit a nop into the instruction stream, and some data into an auxiliary

+ Consumer tools such as gdb or systemtap insert breakpoints on top of
+ the nop, and decode the location operand-strings, like an assembler,

+ The operand strings are selected by the compiler for each operand.

+
+ #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:

+/* 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. */
