Károly Balogh 88b58c3580 i386: added signed 64bit div/mod helpers in assembly. we have some 64bit heavy code where a direct helper results in about 8-10% of performance advantage compared to going through the generic wrapper + the unsigned function		11 年之前
..
cpu.pp	5d57f38619 + functions for FMA and AVX2 detection	11 年之前
fastmove.inc	4b3bf874df * Added CLDs in the RTL i386 inline asm routines, wrapped in {$ifdef	12 年之前
i386.inc	b16c6f8ced * i386 and x86_64 changes for Delphi compatibility:	11 年之前
int64p.inc	88b58c3580 i386: added signed 64bit div/mod helpers in assembly. we have some 64bit heavy code where a direct helper results in about 8-10% of performance advantage compared to going through the generic wrapper + the unsigned function	11 年之前
makefile.cpu	24384c648b * moved genrtti.inc code to rtti	23 年之前
math.inc	fc5f45f65c * sqr(real) and sqrt(real): remove typeconv node inserted by initial call processing (see explanation in comments), allowing these functions to be evaluated using precision of argument. In particular, sqrt(single) and sqrt(double) now emit 'sqrtss' and 'sqrtsd' instructions on x86 targets with -Cfsse3. Non-x86 targets already have the necessary support in code generators.	11 年之前
mathu.inc	b16c6f8ced * i386 and x86_64 changes for Delphi compatibility:	11 年之前
mmx.pp	88c2c77319 + is_sse3_cpu, put into cpu unit, so x86-64 and i386 can share source code	14 年之前
readme	9f31783a0a * old logs removed and tabs fixed	23 年之前
set.inc	4b3bf874df * Added CLDs in the RTL i386 inline asm routines, wrapped in {$ifdef	12 年之前
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 年之前

				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)
