Re: 32x ASM

I use the asmsh.exe to assemble my SH2 ASM files. Unfortunately, the .align directive padds with "0000" (Illegal instruction) and does not allows you to specify the padding value (.align alignment, value). So, I've written this macro : ALIGN_NOP macro .arepeat *%4/2 NOP .aendr endm Then, just call "...

It's an ARM Cortex 8 (single core, 1GHz) coupled with a 49k EL FPGA.

Can't we use the VDP status to guess line number ? Is it not precise enough ?

assembler line number

Hello you all ! In EASy68k, you can use the character "*" as a reference to the current line number. For example, the instruction ds.b $2000-* will reserve a space, padd, from the current line to the $2000 address. Would any of you happen to know if there is a similar way of doing it with our curren...

I think it would be 128 x 32, 64 x 64, or 32 x 128.
