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
git-svn-id: trunk@23325 -
+ 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
git-svn-id: trunk@21393 -
+ 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)

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()
git-svn-id: trunk@20629 -
* moved console io on embedded systems into a seperate unit, this unit might setup input/output e.g. to be redirected to a serial port
* cleanup of the embedded system unit
git-svn-id: trunk@19168 -
* InternalExit: now calls new procedure SysFlushStdIO
* DoneThread: Also calls SysFlushStdIO to avoid loosing output
if standard files are redirected.
git-svn-id: trunk@17798 -
* compiler/ncgrtti.pas:
- objectdef_rtti_class_full:
- don't write the VMT data for helpers
- write the typeinfo of the extended type (something that Delphi does definitely not support :P )
- objectdef_rtti: write the new type kind for helpers instead that of classes
* compiler/symconst.pas: introduce new type kind constant "tkHelper" before "tkFile" (what is that used for btw?)
* rtl/inc/system.inc: add the constant here as well (why wasn't tkUChar added here?)
* objpas/typinfo.pp:
- add tkHelper to the TTypeKind enum (but here tkUChar was added?!)
- extend the TTypeData record with the data of helpers
git-svn-id: branches/svenbarth/classhelpers@17240 -
a) is also set to true for packages (when packages will beimplemented)
b) exists for each package/library/application separately, instead of
being stored in the package containing the system unit (when packages
will be implemented)
