* eliminate warnings in compiler (i386 & i368->x86_64) and minor refactorings
- comment out unused vars and types
- comment out unneeded comparisons (Longword <=> 0)
- suppress some "comparison always true|false" warnings
- tweak visiblity sections

that was set during the typecheck pass because typeconversion nodes
may have been optimised away previously and sometimes the resultdef is
important (e.g. for the value of callparanodes) (mantis #17458)
git-svn-id: trunk@16101 -
to objc_msgSend* into the callnode. This allows reusing the current
call node rather than having to create a new one, and is in particular
necessary because even though the objc_msgSend* functions are declared
as varargs, you're supposed to typecast them to the function type
describing the method before calling them (so they should *not* use
varargs calling conventions!)
* for the above, a field called fobjcforcedprocname has been added to the
callnode, which can be set to a string that will be used as the (mangled)
name of the function to call instead of the mangled name of the procsym
-> fixes calling obj-c methods with floating point arguments on ppc

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 -
instantiated (for wpo)
* also replace vmt-entries for classes for which we don't have any
information at all with FPC_ABSTRACTERROR (since that means they
certainly are not instantiated), except for their published and
virtual class methods
* fixed check for published methods in wpo
git-svn-id: trunk@13219 -
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

* store a node's verbosity in the node so that e.g. disabling warnings
also disables warnings for this node in pass_1
(the above together fix mantis #12076)
* save/restore verbosity with {$push}/{$pop} (mantis #12075)
* if warnings/notes/hints are turned off, also do not count encountered
ones for the totals (otherwise -Sew cannot be used properly in
combination with {$warnings off}, because disabled warnings will still
trigger a compiler error) -- this required adding -vw/-vn/-vh to all
tests using -Sew/-Sen/-Seh
- removed some superfluous state saving/restoring from firstpass()
git-svn-id: trunk@12025 -
* replace derefnode with resolveppuidx method that only needs to be
implemented for nodes referencing other nodes
* fix IE when a label is not defined in inline function
git-svn-id: trunk@11697 -
of u32bit values on 32 bit platforms (after the int64 values have
already been used for overload selection etc, i.e., semantically
nothing changes)
+ test which checks that not too many typecasts are optimized away
git-svn-id: trunk@9664 -
o it's a by-reference parameter, but ignore that since it's
guaranteed to be safe because of the escape analysis
o it's wrapped in an absolute type conversion -> added
actualtargetnode method to tnode which digs through that
git-svn-id: trunk@9412 -
* 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 -
* 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
git-svn-id: trunk@5192 -
allow runtime optimization if the destination is the
same as a source parameter
* tassignmentnode now sets aktassignmentnode global that can be used
to use the left node as a destination parameter and
skip the assignment
* disabled all cpu specific shortstr concat/append
git-svn-id: trunk@4770 -
tarrayconstructornode.inset_typeconvs() and fixed them:
* integers < 32 bit are converted to 32 bit (this was previously
done in the code generator for some targets, and not for others)
* currency is also converted to double for targets where currency = int64
* single is converted to double, except for x86_64 (is at least
necessary on darwin/ppc, darwin/i386 and linux/i386)
* enums are converted to 32 bit ints
* procvars are converted to pointers
* proper errors are given for various unsupported types
NOTE: in C, floating point constants are by default double, while in
FPC they are of type extended. On platforms where extended <> double,
such constants when passed to C varargs are automatically converted
to double by default (gives warning). If you want to pass them as
single or extended or get rid of the warning, use an explicit typecast
* increased ppu version because of introduction of new node flag
(nf_cvarargs for tarrayconstructornode)
* fixed tests/test/cg/tprintf
* changed tests/test/cg/cdecl/taoc5 to use explicit typecasts for
floating point constants passed to C varargs functions.
