* disallow pushfd/popfd for x86_64 (mantis #14862)
* fixed assembling popfq with the internal assembler (it needs a rex.w
prefisx, while pushfq doesn't)
* changed the default opcode size of pushf/popf/pusha/popa in
{$asmmode intel} from "native size" to 16 bit (compatible with Intel
manuals and Kylix; in AT&T mode, the default size for those operations
remains the native one)
* changed pushf/popf in rtl/i386/* into pushfd/popfd because of the
previous change

- sort of reverted r14134, which is no longer required after the above
change (new_section() inserts the alignment itself)
* made the tai_section.create() constructor private so it cannot be
called directly anymore
git-svn-id: trunk@15482 -
used to store a record function result in an MM/FPUREGISTER to memory
(the register size will be OS_F32/OS_F64, while the memory size will
be OS_32/OS_64 -> convert the latter to the former)
* extended tcalext6 to also test this scenario
git-svn-id: trunk@15385 -
because on linux/x86_64
a) the resulting code crashes when using the internal assembler
b) refuses to link when using the external assembler
(and hence I don't know whether it's safe to do on other non-darwin
platforms either) -- fixes mantis #15889
git-svn-id: trunk@14971 -
the opposite meaning, af_stabs_use_function_absolute_addresses), because it
is different on Darwin for the internal and external assembler)
git-svn-id: trunk@14342 -
mark_NoLineinfoEnd
* add "no line info" markers for try/except and try/finally internal cleanup
code, so the debugger doesn't jump back and forth between the end and start
of exception blocks when you arrive at the end
* honour "no line info" markers in dbgdwarf.pas
git-svn-id: trunk@14327 -
+ RTL support:
o VFP exceptions are disabled by default on Darwin,
because they cause kernel panics on iPhoneOS 2.2.1 at least
o all denormals are truncated to 0 on Darwin, because disabling
that also causes kernel panics on iPhoneOS 2.2.1 (probably
because otherwise denormals can also cause exceptions)
* set softfloat rounding mode correctly for non-wince/darwin/vfp
targets
+ compiler support: only half the number of single precision
registers is available due to limitations of the register
allocator
+ added a number of comments about why the stackframe on ARM is
set up the way it is by the compiler
+ added regtype and subregtype info to regsets, because they're
also used for VFP registers (+ support in assembler reader)
+ various generic support routines for dealing with floating point
values located in integer registers that have to be transferred to
mm registers (needed for VFP)
* renamed use_sse() to use_vectorfpu() and also use it for
ARM/vfp support
o only superficially tested for Linux (compiler compiled with -Cpvfpv6
-Cfvfpv2 works on a Cortex-A8, no testsuite run performed -- at least
the fpu exception handler still needs to be implemented), Darwin has
been tested more thoroughly
+ added ARMv6 cpu type and made it default for Darwin/ARM
+ 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
case
* fixed resultdef of tarmtypeconvnode.first_int_to_real in case of
int64->single type conversion
* fixed constant pool locations in case 64 bit constants are generated,
and/or when vfp instructions with limited reach are present
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.

* the objc unit links against the Foundation instead of against the Cocoa
framework, and inludes an interface to either the fragile or non-fragile
obj-c run time depending on the target platform
+ support for the non-fragile Objective-C runtime/ABI, as used on Mac OS X
for ARM (iPhone) 64 bit (PowerPC/64, x86_64) -- all these targets now
are now also supported for the objectivec1 modeswitch
+ support for private_extern symbol bindings, required for the above
* mark objcclasses that are declared in the implementation section of a
unit as "hidden" (not sure what the effect is, since the Objective-C
runtime does not seem to do anything with this flag)
* enabled all obj-c tests for the newly supported platforms

a) it's unnecessary
b) it's slower than "direct" RIP-relative accessing
c) it's not supported on darwin/x86_64 in certain cases
* never use absolute addressing on darwin/x86_64 (like on win64)
* when not generating PIC, make sure that a_loadaddr_ref_reg on x86_64
also uses RIP-relative addressing for darwin/x86_64 and win64

register required classes:
+ add lazy references to classes referred to in the current unit
+ define reference symbols for classes defined in the current unit
+ add lazy references to parent classes of classes defined in the current
unit
git-svn-id: branches/objc@13679 -
changes from that commit, because not hardcoding the use of
current_procinfo in all cases when obtaining the GOT register is
cleaner
git-svn-id: trunk@13470 -
depend on that (and correct a number of cases where this was wrong)
* set the correct subreg type for xmm x86_64 parameter registers
(resolved mantis #14067)
git-svn-id: trunk@13410 -
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
