## ## ppc.library emulation ## (c)1998-99 Frank Wille ## ## PPC assembler stub for calling PowerUp kernel functions. ## Will be used by the "dynamic PowerUp kernel linker". ## ## V0.5c (20.03.1999) phx ## Removed PPCAlert(), PPCPutMessage() and PSYSCALL_xxx(), ## which are not accessible in the original kernel. ## V0.4 (27.11.1998) phx ## Included all kernel symbols of ppc.library V46.19, ## except _KERNEL_xxxxx. ## Rework of _kernel_entry: ## r2 is initialized as TOC pointer, PPCLibBase is saved on stack. ## Save and restore r2 (although not used under SVR4-ABI). ## V0.1 (15.11.1998) phx ## First partially working ppc.library emulation. Synchronous PPC ## tasks, started by runelf, which only use the basic PowerUp kernel ## functions for I/O, memory and context-switch seem to work fine. ## V0.0 (13.11.1998) phx ## created ## .file "kernelcall.s" .include "warpos_lvo.i" .set PPCBIAS,(-450+2) .macro kern li r11,PPCBIAS b _kernel_entry .set PPCBIAS,PPCBIAS-6 .endm .text .globl _kernel_entry _kernel_entry: mflr r0 stw r0,4(r1) #
