+; Macros for "printing" for debug purposes from within asm code
+;
+; The basic macros are:
+; DBGPRINT16, DBGPRINT32, DBGPRINT64, DBGPRINT_XMM, DBGPRINT_YMM, DBGPRINT_ZMM
+; These are called with 1 or more arguments, all of which are of the
+; size/type as specified in the name. E.g.
+; DBGPRINT64 reg1, reg2, reg3, ...
+;
+; There is also a macro DEBUGPRINTL that takes one argument, a string. E.g.
+; DBGPRINTL "hit this point in the code"
+;
+; There are also variations on these with the "DBGPRINT" suffixed with "L", e.g.
+; DBGPRINTL64. These take two or more arguments, where the first is a string,
+; and the rest are of the specified type, e.g.
+; DBGPRINTL64 "Rindex", Rindex
+; Essentially, this is the same as a DBGPRINTL followed by DBGPRINT64.
+;
+; If DO_DBGPRINT is defined, then the macros write the debug information into
+; a buffer. If DO_DBGPRINT is *not* defined, then the macros expand to nothing.
+;
+; CAVEAT: The macros need a GPR. Currently, it uses R15. If the first register
+; argument is R15, then it will use R14. This means that if you try
+; DBGPRINTL64 "text", rax, r15
+; you will not get the proper value of r15.
+; One way to avoid this issue is to not use multiple registers on the same line
+; if the register types are GPR (i.e. this is not an issue for printing XMM
+; registers). E.g the above could be done with:
+; DBGPRINTL64 "test", rax
+; DBGPRINT64 r15
+;
+; Note also that the macros only check for r15. Thus is you tried something
+; like (after token expansion):
+; DBGPRINT32 r15d
+; you won't get the right results. If you want to display r15d, you should
+; print it as the 64-bit r15.
+;
+; To actually print the data, from your C code include the file
+; "dbgprint.h". The default buffer size is 16kB. If you want to change
+; that, #define DBG_BUFFER_SIZE before including "dbgprint.h".
+;
+; Then, (after your asm routine(s) have returned, call
+; print_debug() or print_debug(file pointer)
+; If you do not specify a file pointer, it defaults to stdout.
+;
+; Printing the debug data also resets the write pointer to the beginning,
+; effectively "deleting" the previous messages.
