- rm ifdefs for i8086 far code memory model when doing stack traces. The
compiler will now choose the correct overload of HexStr according to the
CodePointer type.

* As a first part of cleanup, replaced StackTop with function returning StackBottom+StackLength.
* On Win32 and Win64, StackTop returns the stack base from TIB instead.

+ codepage support for textrec/filerec and the above routines
* textrec/filerec now store the filename by default using widechar. It is
possible to switch back to ansichars using the FPC_ANSI_TEXTFILEREC define.
In that case, from now on the filename will always be stored in
DefaultFileSystemEncoding
* fixed potential buffer overflows and non-null-terminated file names in
textrec/filerec
+ dodirseparators(pwidechar), changed the dodirseparators(pchar/pwidechar)
parameters into var-parameters and gave those routines an extra parameter
that indicates whether the p(wide)char can be changed in place if
necessary or whether a copy must be made first (avoids us having to make
all strings always unique everywhere, because they might be changed on
some platforms via a pchar)
* do_open/do_erase/do_rename got extra boolean parameters indicating whether
the passed pchars point to data that can be freely changed (to pass on to
dodirseparators() if applicable)
* objects.pp: force assign(pchar) to be called, because
assign(array[0..255]) cannot choose between pchar and rawbytestring
versions (and removing the pchar version means that assign(pchar) will
be mapped to assign(shortstring) in {$h-})
* fixed up some routines in other units that depend on the format of
the textrec/filerec.name field
git-svn-id: branches/cpstrrtl@25137 -
* renamed platform-specific pchar versions of those rouines to do_*() and
changed them to either rawbytestring or unicodestring depending on the
FPCRTL_FILESYSTEM_SINGLE_BYTE_API/FPCRTL_FILESYSTEM_TWO_BYTE_API setting
* implemented generic shortstring versions of those routines on top of either
rawbytestring or unicodestring depending on the API-kind (in case of the
embedded target, if ansistring are not supported they will map directly
to shortstring routines instead)
* all platform-specific *dir() routines with rawbytestring parameters now
receive their parameters in DefaultFileSystemCodePage
- removed no longer required ansistring variants from the objpas unit
- removed no longer required FPC_SYS_MKDIR etc aliases
* factored out empty string and inoutres<>0 checks from platform-specific
*dir() routines to generic ones
o platform-specific notes:
o amiga/morphos: check new pathconv(rawbytestring) function
o macos TODO: convert PathArgToFSSpec (and the routines it calls) to
rawbytestring
o nativent: added SysUnicodeStringToNtStr() function
o wii: convert dirio callbacks to use rawbytestring to avoid conversion
+ test for unicode mk/ch/rm/getdir()
git-svn-id: branches/cpstrrtl@25048 -
getdir(rawbytestring):rawbytestring so it can accept strings in any
encoding and cleanly return results in DefaultRTLFileSystemCodePage
+ getdir(unicodestring):unicodestring
* renamed the getdir implementation of all platforms except for embedded-
without-ansistring-support to do_getdir(), and depending on the
FPCRTL_FILESYSTEM_SINGLE_BYTE_API/FPCRTL_FILESYSTEM_TWO_BYTE_API define
changed its shortstring parameter to ansistring or unicodestring. The
do_getdir(rawbytestring) routine should just set the code page of the
return value to DefaultFileSystemCodePage without conversion (not
DefaultRTLFileSystemCodePage with conversion, that conversion is performed
in getdir if necessary; this avoids double conversions in case
getdir(unicodestring) is called)
+ generic getdir(shortstring) for platforms supporting either ansistrings or widestrings
o platform maintainers:
o OS/2: adjust code to supports paths > 255 characters if those are supported
o Wii: adjust used callback to use rawbytestring to support paths > 255 characters and
avoid shortstring->rawbytestring conversion overhead
o Windows: GetCurrentDirectoryW is now always used (to prevent data loss)
git-svn-id: branches/cpstrrtl@24993 -
that the type of the parameters can be determined automatically
o added compilerproc declarations for all helpers called in the compiler
via their assembler name, so we can look up the corresponding procdef

+ CPUARM_HAS_BX is defined if the CPU supports the BX* instruction
+ CPUARM_HAS_REV is defined if the CPU supports the REV instruction. Note that you still have to check for compiler versions > 2.6.0 since the assembler reader of 2.6.0 does not understand that instruction.
+ CPUARM_HAS_IDIV is defined if the CPU supports the sdiv, udiv instructions. Use of this fixes a bug where previously these instruction were only used for armv7-m, while cortex3m cpus also support it.
+ CPUARM_HAS_LDREX is defined if the CPU supports the ldrex/strex instructions. Use of this fixes a bug with armv7(-a) cpus where this path has not been used.
+ SYSTEM_HAS_KUSER_CMPXCHG is defined if the system (mainly OS) support the kuser_cmpxchg functions. Use of this fixes a bug where ARMHF systems did not use it for synchronization (although ARMHF is armv7+ only, i.e. the LDREX path is used anyway)
git-svn-id: trunk@22081 -
get_caller_frame, get_caller_addr and dump_stack
with default NIL value to systemh.inc.
+ Added new get_addr function.
system.inc: Use get_addr and get_frame to call
HandleErrorAddrFrame instead of HandleErrorFrame
in several error functions.
Modify dump_stack to use frame and addr parameters.
Provide a dummy get_addr function returning nil.
i386/i386.inc, x86_64./x86_64.inc: Provide real
implementation of get_addr function.

and also use this code to trash local variables in inlined routines
o fixes mantis #22088
o makes it possible to also implement it for the jvm target in the future

+ implement trashing of local variables if subroutine is inlined
* fix some errors releated to interproc. gotos and inlining
+ node_count function
* inline cannot be used with iochecking and safecall calling conventions
* track inherited usage
* don't inline if inherited is used

to low addresses in case the target cpu/OS does not support this (enabled
for reads on AIX/PPC because on AIX the first 16KB are readable)
git-svn-id: trunk@20832 -
in code and not in constants. In the case of primitive types constant nodes
are used while complex types like arrays, records and objects use a local
variable which is initialized to zero once at the entry of the method (the
variable is reused if Default() is used for the same type multiple times in
the same method). For this a new compilerproc was added which uses FillChar
to initialize the given memory area to zero.
This fixes Mantis #9420.
+ psystem.pas: Added Default symbol to system unit
+ htypechk.pas: Added function "is_valid_for_default" which checks recursively
whether the given type can be used with Default at all.
Forbidden types are files, helpers, ObjC and C++ types. This
check is used for records, arrays and objects only if the mode
is a non-Delphi one, as Delphi ignores these types on lower
levels.
+ msg/errore.msg: Added error message for unsupported types for Default()
+ symconst.pas: Added a new enum value vo_is_default_var which is used for the
local variables utilized by Default() so their initalization
and finalization can be avoided.
+ pexpr.pas: Add handling of Default() intrinsic to "statement_syssym"
+ ninl.pas: Extended tinlinenode by a method which returns the correct node for
a Default() and used that method in handle_typecheck.
* ncgutil.pas: Check for new flag "vo_is_default_var" when initializing and
finalizing local variables.
* ppu.pas: increase PPU version
+ psub.pas:
* Added a new routine which zeros defaultvars of a symtable.
* Use this routine inside "initializevars".
* Also use this routine to initialize the staticsymtable of the unit/program.
* Adjusted ppudump, because of the new enum value.
+ Added implementation of fpc_zeromem to system unit.
+ Added tests for Default()
