Re: [Amforth] Problems with a Duemilanove

Hello Marcin,

This is what I get from avra:

I built avra from git sources fetched 3 Dez 17:13.

The first difference in the code is from this macro (.lst files):
avra:
          .set pc_ = pc
          .org $0000
C:000000   +    jmp_ PFA_COLD
          .ifdef PFA_COLD
          .if (PFA_COLD-pc > 2040) || (pc-PFA_COLD>2040)
C:000000 c6b7      rjmp PFA_COLD
          .endif

 avrasm2:
                 .set pc_ = pc
                 .org $0000
000000 940c 06b8   jmp_ PFA_COLD
                 .org pc_

the second:
avra:
          PFA_INTTRAP:
C:00007b 9380 0060     sts intcur, tosl
C:00007d   +      loadtos
C:00007d 9189      ld tosl, Y+
C:00007e 9199      ld tosh, Y+
C:00007f 9468          set ; set the interrupt flag for the inner interpreter
C:000080   +      jmp_ DO_NEXT

avrasm2:
                 PFA_INTTRAP:
00007b 9380 0100     sts intcur, tosl
00007d 9189
00007e 9199          loadtos
00007f 9468          set ; set the interrupt flag for the inner interpreter
000080 940c 380e     jmp_ DO_NEXT


The first is a different interpretation of the macro but I have no idea how 

intcur: .byte 1

is assembled differently.

Cheers,
Torsten
