	* device/lib/mc51/Makefile.in:
      remove crtxpushr0 and crtxpopr0 from build dependencies.

2026-09-08 Maarten Brock <sourceforge.brock AT dse.nl>

	* device/include/ctype.h,
	* device/lib/iscntrl.c,
	* device/lib/isgraph.c,
	* device/lib/isprint.c,
	* device/lib/isspace.c,
	* device/lib/isxdigit.c: also check msb, for all targets
	* device/lib/mcs51/crtxpushr0.asm,
	* device/lib/mcs51/crtxpopr0.asm: removed
	* device/lib/mcs51/crtxpop.asm,
	* device/lib/mcs51/crtxpush.asm: use acc[4-7] also as mask,
	  add dpl & dph support,
	  made register bank independent
	* device/lib/mcs51/crtcall.asm,
	* device/lib/mcs51/gptr_cmp.asm: moved out of C namespace
	* src/SDCCglue.c: gave the register banks a label rbank<n>
	* src/mcs51/main.c (updateOpRW): added push/pop register bank 0 check,
	  inspired by part of 0013 in patch #466 by Oleg Endo
	* src/mcs51/gen.c (xstackRegisters): removed unsued parameters,
	  reordered bitmask, added R0 support
	  (saveRegisters, unsaveRegisters): use larger bitmask,
	  support all register banks,
	  call renamed sdcc_xpush_regs / sdcc_xpop_regs,
	  no longer need ___sdcc_xpush_regs_r0 / ___sdcc_xpop_regs_r0
	  (saveRBank, unsaveRBank): added parameters to support switching
	  register bank and saving psw, bits, dpl, dph & b, also on xstack
	  (genSendBits): factored out of genSend(),
	  optimize literal assignments, already in place bits & try not to use B
	  (genPcall): use renamed sdcc_call_dptr
	  (genFunction): use rbank<n> labels for equ's
	  let saveRBank() push psw, bits, dpl, dph & b, possibly on xstack
	  (genEndFunction): let unsaveRBank() pop psw, bits, dpl, dph & b,
	  possibly from xstack
	  (genCmp, gencjneshort): used renamed sdcc_gptr_cmp
