Kugel Fuhr	5db2aed129	Allow "sp" as an alias for "c_sp" for backwards compatibility. Using it will ... work but generates a linker warning. Added a test to check for this warning.	2025-06-26 07:40:04 +02:00

Oliver Schmidt	419eb700b5	Renamed INITBSS to INIT and INIT to ONCE. ... The way we want to use the INITBSS segment - and especially the fact that it won't have the type bss on all ROM based targets - means that the name INITBSS is misleading. After all INIT is the best name from my perspective as it serves several purposes and therefore needs a rather generic name. Unfortunately this means that the current INIT segment needs to be renamed too. Looking for a short (ideally 4 letter) name I came up with ONCE as it contains all code (and data) accessed only once during initialization.	2016-03-06 21:27:19 +01:00
