i386
florian 22ab6dd329 * disabled mm procs again, they are not usable yet neither supposed to be 5 years ago
..
cpu.pp 77cf67b59a o unified interface of i386 and x86-64 cpu unit: 9 years ago
cpuh.inc 22ab6dd329 * disabled mm procs again, they are not usable yet neither supposed to be 5 years ago
cpuinnr.inc 70a836c4a2 * first part of merging parts of Jeppe's intrinsics patch, mainly r31135 5 years ago
cpumminnr.inc 70a836c4a2 * first part of merging parts of Jeppe's intrinsics patch, mainly r31135 5 years ago
cpummprocs.inc 70a836c4a2 * first part of merging parts of Jeppe's intrinsics patch, mainly r31135 5 years ago
fastmove.inc f4ecf87a50 Add conditional FASTMOVE_DISABLE_SSE3 to be able to discard SSE specific code, needed for Watcom Assembler support 8 years ago
i386.inc 3e6e72118b * keep stack aligned to 16 byte boundaries in assembler subroutines calling other subroutines 6 years ago
int64p.inc 7213a13081 * split fpc_mul_<64 bit> into separate procedures with and without overflow checking 8 years ago
makefile.cpu ff86c80176 * cpu specific header file for the system unit: cpuh.inc, moved several declarations into it 7 years ago
math.inc d1e091d5a3 Use .byte substitutes for ldmxcsr and stmxcsr instructions 8 years ago
mathu.inc b16c6f8ced * i386 and x86_64 changes for Delphi compatibility: 11 years ago
mmx.pp efafecbf9f Also use .byte version of emms instruction 8 years ago
ports.inc 3673f03841 * set the stdcall calling convention explicitly for each method, that requires 7 years ago
portsh.inc 8e6205aca6 * changed the visibility of the writeport and readport methods in the ports unit 7 years ago
readme 9f31783a0a * old logs removed and tabs fixed 23 years ago
set.inc 4b3bf874df * Added CLDs in the RTL i386 inline asm routines, wrapped in {$ifdef 12 years ago
setjump.inc 74f9d719f1 * i386-win32 setjmp and longjmp: if SEH support is enabled, save/restore head of exception registration chain. Without this, a longjmp out of a function with exception frame(s) will leave these exception frames below ESP, which will fail integrity checks in OS and cause process termination if an exception occurs later on (or they may be overwritten by subsequent operations on stack and, again, cause undesired results). 11 years ago
setjumph.inc 74f9d719f1 * i386-win32 setjmp and longjmp: if SEH support is enabled, save/restore head of exception registration chain. Without this, a longjmp out of a function with exception frame(s) will leave these exception frames below ESP, which will fail integrity checks in OS and cause process termination if an exception occurs later on (or they may be overwritten by subsequent operations on stack and, again, cause undesired results). 11 years ago
strings.inc 39dc58de09 - removed one asm instruction from i386's StrEnd() implementation 7 years ago
stringss.inc e4b05477e1 * put the cld instructions behind {$ifdef FPC_ENABLED_CLD} in i386/strings*.inc 12 years ago

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)
