Tee-Kiah Chia 6a29f57715 int2f: fix call interface around syscall_MUX14( ) (inthndlr.c) 
The issues are similar to those surrounding int2F_12_hanndler( )
(see https://github.com/FDOS/kernel/issues/11).

Bart Oldeman 8ee8135d4f ia16-elf-gcc port: use CDECL = __attribute__((cdecl)) instead of varargs. 2018-07-12 10:56:26 -04:00
Tee-Kiah Chia 49d1939ed7 ia16-elf-gcc: remove need for far function wrappers 2018-07-08 18:10:18 +08:00
Bart Oldeman ce8e4fd091 Use static for GCC, which makes the kernel smaller (automatic inlining) 2018-01-11 17:50:31 -05:00
Bart Oldeman 89d97b18de Fix ASMCFUNC (FAR) functions for ia16-elf-gcc. 
We need to use make the functions vararg (,...) to make them cdecl.
For FAR functions we need wrappers.

Bart Oldeman 97003a8aca Introduce popargs and arg macros to distinguish PASCAL/STDCALL conventions. 
GCC has -mrtd but the args are pushed in reverse versus PASCAL. So asm
routines have to use macros to obtain the stack arguments.
For the complex call_nls assembly, revert the arguments in C using a
preprocessor macro.

Bart Oldeman 71a7d0d264 ia16-elf-gcc: provide GNU LD linker script and symbols to link kernel. 
The resulting kernel and sys.com do not work yet (kernel prints 123 only).
Some functions in sys.com are placeholders.

Bart Oldeman fbdbc4c25c C source code changes so the kernel can compile with ia16-elf-gcc. 
Use "make all COMPILER=gcc".
Linking does not work yet with these changes.
