[Sdcc-user] How to remove default setup code?

[Scott B. <br...@ri...>]

Hello.  I'd like to give all the setup code that's linked into my hex
file a miss and jump (more or less) straight from the reset vector to
my main routine.  This seems like it would be a common request but I
can't figure out how to do it.

Right now, my hex file includes almost 400 bytes of:

    mov rb0r1,#81h  ; 00c5   75 01 81   u..
    mov rb0r2,#82h  ; 00c8   75 02 82   u..
    mov rb0r3,#83h  ; 00cb   75 03 83   u..
    mov rb0r4,#84h  ; 00ce   75 04 84   u..
    mov rb0r5,#85h  ; 00d1   75 05 85   u..
    mov rb0r6,#86h  ; 00d4   75 06 86   u..
    ...

Why would anybody want to do this?  More importantly, is there an
easy way to turn it off?  I like the reset values better anyway.  :)


Right now my entire program runs as an _sdcc_external_startup routine
that never returns.  I'd like to recover the 400 bytes of setup code
since it never gets executed anyway.

Other than this minor issue, sdcc has been terrific.  What a pleasant
change from the bloaty Windows IDEs!  Thanks,

    - Scott
