Virgil Dupras	d08a9711c5	boot: make HERE point to RAMEND instead of CURRENT ... The former was only used in the peculiar context of "/emul". The regular case is actually HERE pointing to RAMEND on boot.	2020-04-13 11:43:15 -04:00

Virgil Dupras	f62376bd0a	boot: remove _bend ... It's not needed anymore now that the boot binary is built in one pass.	2020-04-10 09:59:45 -04:00
Virgil Dupras	7aa1be070b	emul: build boot binary in one pass ... ... instead of building boot.fs, and then z80c.fs/icore.fs in separate passes. This strengten xcomp by making it support 2 completely separate dicts (that is, the X dict is *not* connected to the system dict. The chain now stops at EXIT def in boot.fs).	2020-04-10 09:55:58 -04:00

Virgil Dupras	400f0ab0b0	boot: fix flagsToBC ... Why did I ever think that using CM was a good idea? any comparison with numbers more than 0x8000 apart would be wrong...	2020-04-07 11:26:37 -04:00

Virgil Dupras	941791d609	forth: remove RAMSTART and RS_ADDR from stable ABI	2020-04-02 11:39:40 -04:00
Virgil Dupras	68a7be3707	forth: Remove RAM offsets from stable ABI ... Doing this was a bit stupid. These offsets are constants. Moreover, having them in stable ABI had us construct the boot binary from the stable ABI of the host, making it very difficult to change RAMSTART for a new system.	2020-04-02 10:20:51 -04:00
Virgil Dupras	d0c5d3a741	Forth self-bootstraps!!! ... This commit cuts Forth's dependency on zasm. It now self-assembles its own boot-binary! Things are a bit messy now, I'll clean up later.	2020-04-01 22:19:37 -04:00
