Checking into the objects that it fails on (fails on different things depending on the order of input objects on the command line). 0x2c8 in syscall_other.o doesn't actually reference any...

A switch from GCC 7.2.0 down to GCC 4.9.4 while keeping the latest binutils seems to have fixed this. pdp11-aout-objcopy fuzix.aout -O binary ../fuzix.bin joel@rand:~/FUZIX % ls -l Kernel/fuzix.bin -rwxr-xr-x...

I've been toying with linking C to some rl ard rx bootloaders, with @captnapalm 's suggestion. The 7.3.0 GCC with most recent binutils appears to build correct code. So far...

With binutils 2.41 and GCC 13.2.0 it seems to build a valid kernel, with .data moved back to its normal spot after .text. Produces a ~37 kB binary file. Loaded...

Until the disk boot loaders are working, it may be helpful to load the kernel binary directly into RAM. SIMH expects a PDP-11 load tape file for its "load" command....

GCC 13.2.0 seems to be generating incorrect code with -Os optimization at least ```` ttyready_t tty_writeready(uint8_t minor) { uint8_t c = *uart_txstatus; return (c & 0x80) ? TTY_READY_NOW : TTY_READY_SOON;...

The Apple II would be a good target for that too. A small bootloader can load a 40 KB or so binary image from disk. I have the sketch of...
