fd83fd5779 m68k-linux: try to be as ColdFire compatible in the startup code as possible, so explicitly use jsr, otherwise this might compile to a long bsr, that is not CF compatible (except cfv4) 2022-08-31 22:14:15 +02:00

3053f8c2e8 * many syscallh header files had GPL license instead of modified. I owned the copyright, or in one case, Thomas did, but it was a full copy of mine. -> changed to modified

15ff2c1236 * m68k: Fixed name of ELF interpreter, and updated cprt0.as to somewhat working state. Now a "hello world" program using libc can be linked and launched, but anything more complex needs another round of fixing the parameter passing code, in order to get the stack properly balanced.

e734ca7a9b M68k: Fix passing of environment variables. Fixes the compiler not being able to execute the external assembler and linker. 
* rtl/linux/m68k/prt0.as:
    between the arguments and the environment variables is a NULL; keep this in mind when loading the address of the first environment variable.

c6d60979d2 set errno after syscalls. this fixes tiorte test at least. this code ideally should be in assembly, but it seems the assembler reader needs some fixing first...

1e48c7c930 Now that spilling correctly works on m68k we definitely need to store/restore the registers inside the FpSyscall functions. Fixes quite some tests. 
* rtl/linux/m68k/syscall.inc:
    Remove "assembler" modifier and instead use an inline asm block with an accurate list of modified registers so that the compiler correctly stores/restores them

fdf6b17421 rtl/linux/m68k/prt0.as: 
correctly calculate and pass on the addresses for the parameters and the environment; this way parameters can now be used, but reading environment variables still does not seem to work...

Note: the other assembler files (especially cprt0.as) were not adjusted and might not work at all

7bc5995d4d Implement SysCall interface for m68k-linux. This is especially useful for testing code using 
QEMU's userspace emulation as no libraries are needed then.

322dbe5b65 Various adjustments to the RTL for m68k: 
* enable the 6 parameter syscall variant (still everything dummied out though)
* add termios constants
* don't change signal handlers for now
* disable assembly set routines as set handling was changed

d5523e6af6 For now completely disable (I)MUL/(I)DIV support for Coldfire and pass through the RTL routines 
(of which the names had changed from FPC_MUL_LONGWORD->FPC_MUL_DWORD and FPC_MOD_CARDINAL->
FPC_MOD_DWORD).
Also disable the usage of FPU opcodes for Coldfire.

2139a229d3 + If no unit is used, no symbol inside the system unit is used, 
and no language features requiring initialization are used,
    do not initialize units, but just configure the fpu and

92ff07deaf * several fixes by Pierre Pede (parts of his patch to mantis #12492) 
o fixed gprof under linux/i386
    o fixed pic-compilation of the linux/i386 rtl
    o initialisation of linux shared libraries is now possible with pic-code

f6d452c2c0 * remove the RTL's installed signal handlers at the end of the system 
unit's initialization code in case we're in a library
  + implemented InquireSignal(), AbandonSignalHandler(), HookSignal() and
    UnhookSignal() in the sysutils unit
  * for Kylix compatibility, these routines support operating on
    SIGINT and SIGQUIT as well, although they are not hooked by default
    by FPC. The run time errors/exception codes for these signals are
    resp. 217 and 233 (same as in Kylix; I changed ENoWideStringSupport
    to 234).
  * changed the BSD syscall version of fpsigaction to use pointer
    rather than "var" arguments (compatible with other targets, and
    required to be able to pass nil arguments inside the system unit)
  -> together fixes mantis #12704
