a8f466c400 * updated the CSeg, DSeg and SSeg rtl functions on i8086 to use the new x86 
intrinsics for reading the segment registers

git-svn-id: trunk@39434 -
 2018-07-11 14:34:05 +00:00
nickysn
9272bf59b2 + added x86 (i8086, i386 and x86_64) intrinsics fpc_x86_get_cs/ss/ds/es/fs/gs 
for getting the value of x86 segment registers

8e6205aca6 * changed the visibility of the writeport and readport methods in the ports unit 
objects to private (since they should be accessed only through the default
  indexed property)

git-svn-id: trunk@39421 -
 2018-07-09 14:55:20 +00:00

5318a04a5b * moved the interface and implementation parts of the i8086-msdos ports unit to 
include files portsh.inc and ports.inc in the i8086 rtl directory

git-svn-id: trunk@39396 -
 2018-07-06 15:41:44 +00:00

ff2fff365f + added x86 compiler intrinsics fpc_x86_sti and fpc_x86_cli, which generate the 
'sti' and 'cli' instructions

 2018-07-04 16:48:34 +00:00
nickysn
1c9d0d445b * moved the compiler intrinsics for the i8086 'in' and 'out' instructions to the 
system unit (with a 'fpc_x86_' prefix added)

26a3ac3fd4 * moved the fpc_in_x86_*port* constants to the system unit in cpuinnr.inc in the 
i8086, i386 and x86_64 rtl directories. This is done for consistency with
  other compiler internal function numbers (which are declared in innr.inc).

29f307589e + added an i8086-specific procedure MoveData, that allows moving of far data, 
regardless of the memory model; procedure interface is the same as a similar
  Turbo C (and DJGPP) function

bc8c1ea1bc * fixed get_caller_frame() for win16 (on that platform, bp is incremented by 
one, before pushing, to indicate a far call, so it has to be aligned by 2
  again, after reading)

git-svn-id: trunk@37657 -
 2017-12-01 23:00:47 +00:00

e8a09fba0d * use xchg, instead of mov, because it's 1 byte shorter

34113b930b * removed the checkoverflow: boolean parameter of the software mul helpers;

nickysn
024ebb287e + implemented set_jmp and long_jmp on win16 via the Catch and Throw winapi

2f83e2efc9 * use 'seges' instead of db 26h. It is actually supported, but for some reason,
