(********************** User-Trigerred Conditionals **********************)

{  Those conditionals below can be enabled in your project Options,
   to tune the compilation depending your setup or your project expectations. }

{.$define PUREPASCAL}
// define this if your compiler doesn't support Delphi's x86 asm
// - is set automaticaly in case of a 64 bits compiler (only FPC exists now)

{$define USENORMTOUPPER}
// if defined, text functions will use the NormToUpper[] array, as defined
// in our custom SysUtils.pas (not the LVCL version) -> when using LVCL,
// define the global LVCL compiler directive, and this unit will initialize
// its own NormToUpper[] array
// -> define ENHANCEDRTL conditional below if our Enhanced RTL IS installed
// -> in practice, this conditional is ALWAYS DEFINED, since needed by SQLite3

{.$define ENHANCEDRTL}
// define this if you DID install our Enhanced Runtime library or the LVCL:
// - it's better to define this conditional globaly in the Project/Options window
// - we need to hack the "legacy" LoadResString() procedure and add a
//   LoadResStringTranslate() function, for on the fly resourcestring i18n
// - it will also define the TwoDigitLookup[] array and some very fast x86 asm
//   IntToStr() and other functions, available in our Enhanced Runtime library
//   (and our LVCL library)
// - it will be unset automaticaly (see below) for Delphi 2009 and up
// - this conditional must be defined in both SQLite3Commons and SQLite3i18n units,
//   or (even better) globally in the Project options

{.$define USEPACKAGES}
// define this if you compile the unit within a Delphi package
// - it will avoid error like "[DCC Error] E2201 Need imported data reference ($G)
//   to access 'VarCopyProc' from unit 'SynCommons'"
// - shall be set at the package options level, and left untouched by default
// - note: you should probably also set "Generate DCUs only" in Project Options
// -> Delphi Compiler -> Output C/C++ -> C/C++ output file generation

{.$define DOPATCHTRTL}
// if defined, some low-level patches are applied to Delphi or FPC RTL
// - you should better use it, but we have unset it by default

{.$define NEWRTTINOTUSED}
// if defined, the new RTTI (available since Delphi 2010) won't be linked to
// the executable: resulting file size will be much smaller, and mORMot won't
// be affected (unless you use the enhanced RTTI for record/dynamic array JSON
// serialization) - left undefined by default to ensure minimal impact

{.$define NOSETTHREADNAME}
// if defined, SetThreadName() would not raise the exception used to set the
// thread name: to be defined if you have issues when debugging your application

{.$define NOEXCEPTIONINTERCEPT}
// if defined, exceptions shall not be intercepted and logged

{.$define USELOCKERDEBUG}
// by default, some IAutoLocker instances would use TAutoLocker, unless this
// conditional is defined to use more verbose TAutoLockerDebug
// (may be used for race condition debugging, in multi-threaded apps)

{.$define OLDTEXTWRITERFORMAT}
// force TTextWriter.Add(Format) to handle the alternate deprecated $ % tags

{.$define FORCE_STRSSE42}
// sse4.2 string instructions may read up to 16 bytes after the actual end buffer
// -> define this if you want StrLen/StrComp/strspn/strcspn to use SSE4.2 opcodes
// but you would eventually experiment weird random GPF in your project, raising
// unexpected SIGABRT/SIGSEGV under POSIX system: so is disabled below for our
// LINUX conditional - and use at your own risk under Windows!

{.$define DISABLE_SSE42}
// if defined, no SSE4.2 nor AES-NI instruction will be used, i.e. disable
// FORCE_STRSSE42 and all crc32c opcodes - is set for FPC DARWIN target

{.$define WITH_ERMS}
// you may define this to enable REP MOVSB/STOSB for Fillchar/Move if cfERMS
// flag is available in Intel's CpuFeatures
// -> disabled by default, since in practice it is (much) slower for small blocks

{.$define NOXPOWEREDNAME}
// define this to avoid sending "X-Powered-By: Synopse mORMot" HTTP header

{.$define SQLVIRTUALLOGS}
// enable low-level logging of SQlite3 virtual table query planner costs
// -> to be defined only for internal debugging

{.$define NOSYNDBZEOS}
// made SynDBZeos.pas a "void" unit - defined for FPC/Lazarus packages only

{.$define DDDNOSYNDB}
// SynDB / external SQL DB won't be linked to the executable by dddInfraSettings
{.$define DDDNOMONGODB}
// Mongo DB client won't be linked to the executable by dddInfraSettings

{ Free Pascal adaptation notes:
  - we use the Delphi compatibility mode
  - from system.pp use these constants (Win32/64 values listed):
      LineEnding = #13#10;
      DirectorySeparator = '\';
  - for Cross-Platform and all CPU:
      integer is NOT CPU-dependent (thanks to objpas), i.e. always 32 bits
      cardinal is NOT CPU-dependent (thanks to objpas), i.e. always 32 bits
      PtrUInt is an unsigned integer type of same size as a pointer / register
        -> must be used for pointer arithmetic
        -> may be used in loops
      PtrInt is a signed integer type of same size as a pointer / register
        -> must be used for pointer arithmetic
        -> may be used in loops
      all 32 bits x86 asm code is replaced by a pascal only version, if the
      conditional PUREPASCAL is defined (e.g. for CPUX64)
