Merge: 7082b6e34a 88f83280dc

Merged riscv_new branch

+ created branch for keyboard/video/mouse unit unicode support development

+ added tests directory

+ add svn:needs-lock to kbd_us.ods, because it's a binary file (and therefore,
unmerge-able)

* access the Default8087CW global variable directly from within inline asm,
instead of copying it to a local var first, since the concern about PIC code
(this asm code started out as a copy of the i386 rtl code) doesn't exist on
the i8086, since there's no such thing as PIC code on the i8086

* optimize the i8086 backwards move by using movsw instead of movsb in the Move
and MoveData procedures

+ added asm optimized version of fpc_pwidechar_length for i8086

* place the "external" directives in the interface instead of in the
implementation, because we don't support "external" in the implementation
for C varargs functions for LLVM (can't generate a stub for them)
o having "external" in the implementation also causes useless overhead
with code generators that do support this

+ added the initial implementation of my C structure checker code generator
tool, named h2paschk. This is currently a separate tool, that requires a
manually crafted input file with a special syntax (example is included as a
comment in the source code), that contains descriptions of all the records
that need to be checked, but it is planned to add support to h2pas to generate
these files automatically, since this would be very useful.

+ added h2paschk structure checker files for the DirectDraw and DirectInput
header translations, used by PTCPas.

Avoid C 64-bit compiler warnings by using %lu instead of %u for sizeof and offsetof

* fixed floating point div-by-zero RTE code on Darwin (208 instead of 200,
fixes webtbs/tw32671)

* fixed Darwin/AArch64 flt/int-div-by-zero error codes (fix for 42045, as
noted by AlexeyT)

Avoid range check error when compiled -Criot option

Fix bug report 35937 by simple assembly code change and add test

* the final build of packages and rtl are compiled with the general tls model on i386 as they could be used in dyn. libraries.
This does not hurt much as the linker optimized the threadvar access if possible

* arm uses the same approach as i386: during the final build of the rtl and the packages, the general dynamic tls model is selected

Define FPC_IS_SYSTEM at start of all system.pp source

Add riscv32 mathu inculde file, redirecting to ../riscv64/mathu.inc file (this file seems to have no 64-bit specific code)

used

Try to fix problems for more recent GDB versions.
Move GDB_NEW_UI macro def. to GDB_VER_GE_712
Add GDB_INTERP_LOOKUP_HAS_UI and GDB_HAS_SAVED_COMMAND_LINE_BUT_NO_SIZE
to same GDB_VER_GE_712.
Use stdio_filopen to create gdb_stdout and gdb_stderr
if GDB_HAS_GET_STDIN macro is set.

* Fix compilation of gdbint unit for go32v2, should resolve bug report 36923.
Replace cint type by longint (as gdbint unit does not use ctypes unit).

* disable CPU and Signals units for Windows on AArch64 for now

* use accessor functions to work with the TContext record

* the prefetch bug handling is specific to x86_64

powerpc64le: fix reading FPU control word after gitlab 000758aa1143

Also, missing rest of the commit message for that change:

The default implementation of SysResetFPU now sets the FPU control word that
was last set from any thread (Delphi and FPC i386/x86-64-compatible). No longer
call SysInitFPU when starting a new thread, only SysResetFPU. Combined, this
means that new FPC-started threads will always start out with that control
word on all architectures.

Added generic fpc_cpuinit implementation that is used unless
FPC_SYSTEM_HAS_FPC_CPUINIT has been defined.

Ensure that the softfloat exception mask is initially set to the same
value as the hardware fpu exception mask on architectures that use both.

SafeLoadLibrary now saves/restores the FPU control word on all platforms.

Removed outdated fpc_mtfsb0_corrected define check in powerpc64.inc

Resolves gitlab 0038230

Thumb(2): fix compilation after FPU control word changes

Resolves gitlab 0039966
