34 * dbnum,base,regnum,bitsz,gapsz,reset,x...)
35 *
36 * s = passed from XCHAL_*_LIST(s), eg. to select how to expand
37 * ccused = set if used by compiler without special options or code
38 * abikind = 0 (caller-saved), 1 (callee-saved), or 2 (thread-global)
39 * kind = 0 (special reg), 1 (TIE user reg), or 2 (TIE regfile reg)
40 * opt = 0 (custom TIE extension or coprocessor), or 1 (optional reg)
41 * name = lowercase reg name (no quotes)
42 * galign = group byte alignment (power of 2) (galign >= align)
43 * align = register byte alignment (power of 2)
44 * asize = allocated size in bytes (asize*8 == bitsz + gapsz + padsz)
45 * (not including any pad bytes required to galign this or next reg)
46 * dbnum = unique target number f/debug (see <xtensa-libdb-macros.h>)
47 * base = reg shortname w/o index (or sr=special, ur=TIE user reg)
48 * regnum = reg index in regfile, or special/TIE-user reg number
49 * bitsz = number of significant bits (regfile width, or ur/sr mask bits)
50 * gapsz = intervening bits, if bitsz bits not stored contiguously
51 * (padsz = pad bits at end [TIE regfile] or at msbits [ur,sr] of asize)
52 * reset = register reset value (or 0 if undefined at reset)
53 * x = reserved for future use (0 until then)
54 *
55 * To filter out certain registers, e.g. to expand only the non-global
56 * registers used by the compiler, you can do something like this:
57 *
58 * #define XCHAL_SA_REG(s,ccused,p...) SELCC##ccused(p)
59 * #define SELCC0(p...)
60 * #define SELCC1(abikind,p...) SELAK##abikind(p)
61 * #define SELAK0(p...) REG(p)
62 * #define SELAK1(p...) REG(p)
63 * #define SELAK2(p...)
64 * #define REG(kind,tie,name,galn,aln,asz,csz,dbnum,base,rnum,bsz,rst,x...) \
65 * ...what you want to expand...
