Just make one, not so hard.

Please note that compiling the RTL or packages with different modes than

Again we don't support compiling the RTL and packages with anything than
the default mode.

This is compatible with Delphi and is required to allow overloads as
noticed by this bug report that triggered this change:
https://bugs.freepascal.org/view.php?id=29444

If it is inconvenient for you, then use PtrInt/PtrUInt.

Not special for this RC but some bugs:

===
1) packages\winunits-base\src\wininet.pp

Compilation error in -Mdelphiunicode: bad declaration of overloaded functions
FindFirstUrlCacheEntry()
FindNextUrlCacheEntry()
with 'W' versions of arguments

Must be equivalent to such with 'A' arguments.

Line 2593:
function FindFirstUrlCacheEntry(lpszUrlSearchPattern:LPCWSTR;
lpFirstCacheEntryInfo:LPINTERNET_CACHE_ENTRY_INFOW; var
lpcbCacheEntryInfo:LongWord):HANDLE;stdcall;external WININETLIBNAME name
'FindFirstUrlCacheEntryW';

Line 2636:
function FindFirstUrlCacheEntry(lpszUrlSearchPattern:LPCWSTR;
lpFirstCacheEntryInfo:LPINTERNET_CACHE_ENTRY_INFOW; var
lpcbCacheEntryInfo:DWORD):HANDLE;stdcall;external WININETLIBNAME name
'FindFirstUrlCacheEntryW';

Line 2637:
function FindNextUrlCacheEntry(hEnumHandle:HANDLE;
lpNextCacheEntryInfo:LPINTERNET_CACHE_ENTRY_INFOW; var
lpcbCacheEntryInfo:DWORD):BOOL;stdcall;external WININETLIBNAME name
'FindNextUrlCacheEntryW';

Line 2656:
function FindFirstUrlCacheEntry(lpszUrlSearchPattern:LPCWSTR; var
lpFirstCacheEntryInfo:INTERNET_CACHE_ENTRY_INFOW;
lpcbCacheEntryInfo:LPDWORD):HANDLE;stdcall;external WININETLIBNAME name
'FindFirstUrlCacheEntryW';

Line 2657:
function FindNextUrlCacheEntry(hEnumHandle:HANDLE; var
lpNextCacheEntryInfo:INTERNET_CACHE_ENTRY_INFOW;
lpcbCacheEntryInfo:LPDWORD):BOOL;stdcall;external WININETLIBNAME name
'FindNextUrlCacheEntryW';

===

2) rtl\win\wininc\struct.inc

Members 'lData' of NEWCPLINFOA/NEWCPLINFOW have different types. I think
both must be LONG_PTR.

Member 'code' of NMHDR must have 'Integer' type, becouse constants, used
here, are signed. This cause wrong comparison results or require explicit
cast everywhere in user code.

===

3) This bug still exists:

https://lists.freepascal.org/pipermail/fpc-devel/2016-November/037539.html

===
4) packages\pasjpeg\src\jconfig.inc

There is explicit declaration of {$MODE DELPHI}, so 'pasjpeg' is
incompatible with -Mdelphiunicode.
Can be '{$ifndef UNICODE}{$MODE DELPHI}{$endif}'


===
Just question. Why NativeInt / NativeUInt declaration changed to strong
aliases? To be new Delphi compatible? But this inconvenient in Delphi, and
so in FPC. Old code become broken.

I regret to say that I can't reproduce my initial result showing 9%
improvement on 3.2.0rc1 against 3.0.4. Both versions show the same speed
now.

I also compared 3.0.4 against trunk in another environment:
Ubuntu 18.04.2 LTS (GNU/Linux 4.15.0-1014-gcp x86_64)
cpu model name: Intel(R) Xeon(R) CPU @ 2.00GHz

This is the raw result from 3.0.4:
640 Examples seen. Accuracy:0.1006 Error:   1.79914 Loss:2.31176 Threads: 4
Forward time:  0.99s Backward time:  0.77s Step time:  1.51s

This is the raw result from trunk:
640 Examples seen. Accuracy:0.1175 Error:   1.79696 Loss:2.30112 Threads: 4

I usually look at the "Step time" for comparisons.

Re: [fpc-devel] FPC 3.2.0RC1 released!

[J. Gareth Moreton]

With your permission I'd like to use this project as part of my work to 
improve the peephole optimiser, among other things.  Any improvements 
probably won't happen until the version after 3.2.0, but I like a challenge!


J. Gareth Moreton, aka. Kit

P.S. One of the things I introduced into FPC 3.2.0 is the "vectorcall" 
calling convention for x86_64-win64.  It's currently mostly there for 
pure assembler routines and for interfacing with third-party libraries, 
since automatic vectorisation of Pascal code is still rather limited.  
It might be something to experiment with though.

Note that these are for 32bit Windows executables. Also i'm using the 
Lazarus-bundled build mentioned by Martin Frb above.

That's pretty good!  I guess our individual work on the compiler. while

  Michael,

  I remember that I was also asking why you did not put the shared lib
into the lib/fpc/3.2.0/lib subdirectory, but I forgot your explanation...

This one is not really fixable, that's simply a bug in debian.
