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