cpu.pp + more helper routine to check for CPU features added 2021-08-09 23:19:20 +02:00
cpuh.inc + added x86 (i8086, i386 and x86_64) intrinsics fpc_x86_get_cs/ss/ds/es/fs/gs 2018-07-11 14:19:40 +00:00
cpuinnr.inc + added x86 (i8086, i386 and x86_64) intrinsics fpc_x86_get_cs/ss/ds/es/fs/gs 2018-07-11 14:19:40 +00:00
fastmove.inc Add conditional FASTMOVE_DISABLE_SSE3 to be able to discard SSE specific code, needed for Watcom Assembler support 2017-08-04 20:51:58 +00:00
i386.inc * manually merged parts of r42260 to enable further merges 2020-12-30 13:53:10 +00:00
int64p.inc * split fpc_mul_<64 bit> into separate procedures with and without overflow checking 2017-02-19 19:15:14 +00:00
makefile.cpu * cpu specific header file for the system unit: cpuh.inc, moved several declarations into it 2017-11-01 16:33:30 +00:00
math.inc Use .byte substitutes for ldmxcsr and stmxcsr instructions 2017-08-21 13:29:29 +00:00
mathu.inc * i386 and x86_64 changes for Delphi compatibility: 2014-04-25 15:10:12 +00:00
mmx.pp # revisions: 45848 2020-12-08 20:34:55 +00:00
ports.inc * set the stdcall calling convention explicitly for each method, that requires 2018-07-06 15:59:26 +00:00
portsh.inc * changed the visibility of the writeport and readport methods in the ports unit 2018-07-09 14:55:20 +00:00
readme
set.inc * Added CLDs in the RTL i386 inline asm routines, wrapped in {$ifdef 2013-09-29 10:53:49 +00:00
setjump.inc * i386-win32 setjmp and longjmp: if SEH support is enabled, save/restore head of exception registration chain. Without this, a longjmp out of a function with exception frame(s) will leave these exception frames below ESP, which will fail integrity checks in OS and cause process termination if an exception occurs later on (or they may be overwritten by subsequent operations on stack and, again, cause undesired results). 2013-12-16 10:12:36 +00:00
setjumph.inc * i386-win32 setjmp and longjmp: if SEH support is enabled, save/restore head of exception registration chain. Without this, a longjmp out of a function with exception frame(s) will leave these exception frames below ESP, which will fail integrity checks in OS and cause process termination if an exception occurs later on (or they may be overwritten by subsequent operations on stack and, again, cause undesired results). 2013-12-16 10:12:36 +00:00
strings.inc - removed one asm instruction from i386's StrEnd() implementation 2017-11-23 16:43:51 +00:00
stringss.inc * put the cld instructions behind {$ifdef FPC_ENABLED_CLD} in i386/strings*.inc 2013-09-28 12:06:47 +00:00

readme 

This directory contains only RTL parts specific to the processor I386 family.

(They are specific because they contain assembler instructions)

Include files for system are :
  heap.inc (heap handling)
  set.inc  (sets operations)
  math.inc (mathematic operations using the coprocessor)
  i386.inc (several functions/procedures containing assembler parts)
  setjump.inc (setjmp/longjmp implementation for exceptions)
  rttip.inc (rtti handling, for speed reasons)
  
Units are :
  strings.pp (written in assembler for speed)
  cpu.pp     (routines to access cpu info)
  mmx.pp     (special mmx routines)
