Early September work

2025-09-07

fixupp

To help port the default overlay manager of WarpLink to NASM, we had to use symbols starting with a dollar sign. But NASM didn't support those. (In the upcoming NASM v3.00 some support has been added.)

To bridge this gap, I modified the trusty fixupp utility once again. It will now replace one or more leading "D." in section, class, or symbol names by a dollar sign each.

fixmem

I modified fixmem during my use for porting the WarpLink overlay manager.

instsect

Add a NASM v2.17 / v3.00 %note directive to reference nested listing files, used for the boot sector files included using incbin. This allows to create a complete .tls trace listing that includes the boot sector loaders.

lDebug

ident86

The updates to the identicalisation tool are mainly to help identify NASM encoding choice differences, which turned out to all be in xchg reg,reg instructions.

tractest

lDOS kernel
