o separate information for reading and writing, because e.g. in a
try-block, only the writes to local variables and parameters are
volatile (they have to be committed immediately in case the next
instruction causes an exception)
o for now, only references to absolute memory addresses are marked
as volatile
o the volatily information is (should be) properly maintained throughout
all code generators for all archictures with this patch
o no optimizers or other compiler infrastructure uses the volatility
information yet
o this functionality is not (yet) exposed at the language level, it
is only for internal code generator use right now
git-svn-id: trunk@34996 -
- add TTagHashSet class descendant of THashSet with an ability to has also a LongWord value together with key
- change TAsmData.ConstPools[] to be an indexed property to properly initialize ConstPool class, remove pool initialization from all other units
- add ansistring constants to pool together with their encoding to distinct the same text constants with different codepage
+ test
git-svn-id: trunk@19261 -
based on patch by Dmitry Boyarintsev (mantis #14508)
o Todo: while parsing the class declaration, check whether the
field types are valid for use in an obj-c class
* use a common pool for selector names generated by objcselector()
and by the rtti info for implemented classes
git-svn-id: branches/objc@13663 -
associated with an Objective-C protocol. Code generator part will
always generate an internalerror currently, because it cannot yet
be implemented (needs support for generating RTTI for Objective-C
classes)
git-svn-id: branches/objc@13461 -
o support for declaring external Objective-C classes (see
rtl/inc/objcbase.pas), including derived classes
o support for converting methods of objcclasses into selectors
(see tests/test/tobjc1.pp)
o support for loading from/storing to fields of objcclasses
o support for calling Objective-C methods using regular
Object Pascal syntax (see tests/test/tobjc1.pp)
o some things that are known to be not yet working:
o automatic conversion from ID to objcclasses and back
o declaring and implementing new objcclasses/methods in Pascal code
o debug information (objcclasses are currently plain pointers
as far as the debugger knows)
git-svn-id: branches/objc@13162 -
the use of Objective-C 1.0 constructs. Because it is a mode switch, it
can be used cumulatively with every syntax mode. Note that a {$mode xxx}
statement resets all mode switches as well, so you cannot use the
-Mobjectivec1 variant if you have such a statement in a unit. This
modeswitch is currently only enabled for Darwin/PowerPC and Darwin/i386,
as the backend support is not yet implemented for other platforms.
+ implemented selector() statement that can be used to create an Objective-C
selector for the message with the specified *constant* name (in the future,
it will also work for Objective-C method identifiers)
+ added SEL type to the system unit (the selector() statement returns it)
+ added all Objective-C segments to the assembler writers
+ (currently mostly dummy) objc1 unit that is automatically included if the
{$modeswitch objectivec1} statement is used
+ some tests for the selector() statement
