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

context of a class. This can be either the class declaration or
a method implementation
* replaced all current_procinfo.procdef._class with current_objectdef
git-svn-id: trunk@12059 -
a) cpu64bitaddr, which means that we are generating a compiler which
will generate code for targets with a 64 bit address space/abi
b) cpu64bitalu, which means that we are generating a compiler which
will generate code for a cpu with support for 64 bit integer
operations (possibly running in a 32 bit address space, depending
on the cpu64bitaddr define)
All cpus which had cpu64bit set now have both the above defines set,
and none of the 32 bit cpus have cpu64bitalu set (and none will
compile with it currently)
+ pint and puint types, similar to aint/aword (not pword because that
that conflicts with pword=^word)
* several changes from aint/aword to pint/pword
* some changes of tcgsize2size[OS_INT] to sizeof(pint)
git-svn-id: trunk@10320 -
* small cleanups of unused variables in firstpass
* node_resources_fpu() created to get an approximation of the
required fpu registers
* for the moment use node_complexity in the CG until the
node_resource_int() is created
git-svn-id: trunk@8655 -
* rename methodpointerinit/done to callinitblock/callcleanupblock
* moved checks in callnode to separate functions
* funcretnode is now always a simple node instead of a block of
statements
* funcret and methodpointer are generated/optimized only in pass_1 so
a conversion from calln to loadn is much easier
* function result assignments are much more often optimized to use the
assignment destination location instead of using a temp

constants. The default is currently 32 bits/single, which corresponds
to the old behaviour (constants which cannot be exactly represented
in the default/chosen precision will also still be automatically
upgraded to higher precision). Supported constructs:
* Command line switch -CF<x>
* Compiler directive {$MINFPCONSTPREC <x>}
whereby in both cases <x> can be default, 32 or 64. 80 is not supported
because there is no generic way to figure out whether the current target
actually supports 80 bit precision floating point calculations while
parsing the command line switches (pbestreal can still change in case of
win64 or -Cfsse2)
git-svn-id: trunk@8349 -
* fixed some (harmless) ptrint warnings
- removed some commented code in agppcmpw
* added one missing field in a typed constant in cp1251
git-svn-id: trunk@8081 -
high(int64+1)..high(qword) if written in decimal notation) + test
* fixed range checking of qword constants parsed by the compiler
(they always gave a range error if > high(int64), because the compiler
internally stores them as int64)
* turn off range checking flag of rdconstnodes created by the parser
from _INTCONST, because those are already range checked by the
way they are parsed using val()
git-svn-id: trunk@6814 -
* fixed downsizing the precision of floating point values
* floating point constants are now treated using only the minimal
precision required (e.g. 2.0 is now a single, 1.1 extended etc)
(Delphi compatible)
git-svn-id: trunk@5927 -
* symtables based on TFPHashObjectList and TFPObjectList
* rename torddef.typ to torddef.ordtype
* rename tfloatdef.typ to tfloatdef.floattype
* rename tdef.deftype to tdef.typ
* remove obsolete browser code, browcol is kept so the ide
can still be compiled
