o all denormals are truncated to 0 on Darwin, because disabling

values located in integer registers that have to be transferred to
mm registers (needed for VFP)

+ ARMv6+ implementations of atomic operations using ldrex/strex
* don't use r9 on Darwin/ARM, as it's reserved under certain
circumstances (don't know yet which ones)
* changed C-test object files for ARM/Darwin to ARMv6 versions
* check in assembler reader that regsets are not empty, because
instructions with a regset operand have undefined behaviour in that

int64->single type conversion

WARNING: when using VFP on an ARMv6 or later cpu, you *must* compile all
code with -Cparmv6 (or higher), or you will get crashes. The reason is
that storing/restoring multiple VFP registers must happen using
different instructions on pre/post-ARMv6.

starting with a previous 2.3.1 or compiler built from the objc branch
+ added basic objcprotocol support (only for external protocols
currently)
o use in type declaration: "type xp = objcprotocol ... end;"
o when defining a root class that implements it:
"type yc = objcclass(xp) ... end" (note: no support yet
for something like "objcclass(id,xp)" or so)
o when defining a non-root class that implements a protocol:
"type zc = objcclass(nsobject,xp) ... end"
o includes support for "required" and "optional" sections
o no support yet for the objcprotocol(<protocol>) expression
that enables getting a class instance representing the
protocol (e.g., for use with "conformsToProtocol:")
o message names have to specified in protocol declarations,
but if an objcclass implements a protocol, the message names do
not have to be repeated (but if they are, they have to match;
the same goes when overriding inherited methods)
+ allow specifying the external name of Objective-C classes and
protocols, since classes and protocols can have the same name
(and you cannot use the same Pascal identifier in such caseq)
+ added NSObject protocol, and make the NSObject class use it
+ added missing NSObject class methods that have the same name
as instance methods (added "class" name prefix to avoid clashes)
* fixed several cases where the compiler did not treat Objective-C
classes/protocols the same as Object Pascal classes/interfaces
(a.o., forward declarations, alignment, regvars, several type
conversions, ...)
* allow "override" directive in objcclass declarations, and print
a hint if it's forgotten in an external declaration (because it
doesn't really matter there, and may make automated header
conversion harder than necessary) and an error if will be used in
a non-external declaration (because it is not possible to start
a new vmt entry-tree in Objective-C, you can only override parent
methods)

designated parent to NSObject, because you can have multiple root classes

o support for converting methods of objcclasses into selectors

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

as far as the debugger knows)

+ initial implementation of whole-program optimisation framework

o use:
a) generate whole-program optimisation information (no need
to completely compile the program and all of its units

fpc -OWdevirtcalls -FWmyprog.wpo myprog
b) use it to optimise the program
fpc -B -Owdevirtcalls -Fwmyprog.wpo myprog
(the -B is not required, but only sources recompiled during
the second pass will actually be optimised -- if you want,
you can even rebuild the rtl devirtualised for a particular
program; and these options can obviously also be used
together with regular optimisation switches)
o warning:
- there are no checks yet to ensure that you do not use
units optimised for a particular program with another
program (or with a changed version of the same program)

"class of x" has been instantiated rather than a
"class of tobject". this required storing the instantiated

+ symbol liveness wpo information extracted from smartlinked programs
(-OW/-Owsymbolliveness)
+ use symbol liveness information to improve devirtualisation (don't
consider classes created in code that has been dead code stripped).
This requires at least two passes of using wpo (first uses dead code
info to locate classes that are constructed only in dead code,
second pass uses this info to potentially further devirtualise).
I.e.:
1) generate initial liveness and devirtualisation feedback
fpc -FWtt.wpo -OWall tt.pp -Xs- -CX -XX
2) use previously generated feedback, and regenerate new feedback
based on this (i.e., disregard classes created in dead code)
fpc -FWtt-1.wpo -OWall -Fwtt.wo -Owall tt.pp -Xs- -CX -XX
3) use the newly generated feedback (in theory, it is possible
that even more opportunities pop up afterwards; you can
continue until the program does not get smaller anymore)
fpc -Fwtt-1.wpo -Owall tt.pp -CX -XX
* changed all message() to cgmessage() calls so the set codegenerror
* changed static fsectionhandlers field to a regular field called
fwpocomponents
* changed registration of wpocomponents: no longer happens in the
initialization section of their unit, but in the InitWpo routine
(which has been moved from the woinfo to the wpo unit). This way
you can register different classes based on the target/parameters.
+ added static method to twpocomponentbase for checking whether
the command line parameters don't conflict with the requested
optimisations (e.g. generating liveness info requires that
smartlinking is turned on)
+ added static method to twpocomponentbase to request the
section name
