* $CPU/cgcpu.pas: disable the generation of VMT loading code
* dbgstabs.pas, dbgdwarf.pas: treat virtual methods of helpers as normal methods
* ncgcal.pas: don't register virtual helper methods for WPO
* ncgrtti.pas: write virtual helper methods as normal methods to RTTI
* nobj.pas: correctly handle final and override cases in helpers
* pdecvar.pas: property getters
* rautils.pas: no VMT offset in records

- 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

represent complex locations (required for full x86-64 ABI support,
which is not yet implemented) -> lots of special result handling
code has been removed and replaced by the parameter handling
routines
+ added support for composite parameters (and hence function
results) to tcg.a_load_ref_cgpara() (so it can be used for
handling, e.g., 64 bit parameters on 32 bit platforms)
* the above fixed writing past the end of allocated memory when
handling records returned in registers on x86-64 whose size is
not a multiple of 8 bytes (mantis #16357)
- removed the x86-64 and PPC specific versions of a_load_ref_cgpara(),
as they are now handled correctly by the generic version
* moved the responsibility of allocating tcgpara cpu registers
(using paramanager.allocparaloc()) from the callers of
cg.a_load*_cgpara() to the cg.a_load*_cgpara() methods
themselves (so the register allocation can be done efficiently
when dealing with function results)
* for the above, renamed paramanager.alloc/freeparaloc() to
paramanager.alloc/freecgpara(), and use paramanager.allocparaloc()
to allocate individual pcgparalocations instead
* fixed the register size of SSE2 function result registers for
x86-64 (when used for floating point), which results in removing
a few superfluous "movs? %xmm0,%xmm0" instructions
* fixed compilation of paramanagers of avr, m68k and mips after r13695
and also updated them for these new changes

the opposite meaning, af_stabs_use_function_absolute_addresses), because it
is different on Darwin for the internal and external assembler)

* 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
git-svn-id: branches/objc@13763 -
alignment for each memory reference (mantis #12137, and
test/packages/fcl-registry/tregistry1.pp on sparc). This also
enables better code generation for packed records in many cases.
o several changes were made to the compiler to minimise the chances
of accidentally forgetting to set the alignment of memory references
in the future:
- reference_reset*() now has an extra alignment parameter
- location_reset() can now only be used for non LOC_(C)REFERENCE,
use location_reset_ref() for those (split the tloc enum so the
compiler can catch errors using range checking)

(mantis #12685 and also the error message noted in mantis #12576,
although in case of the latter it's only a symptom of another bug)
git-svn-id: trunk@12199 -
the syntax is exactly the same as for "external", except for
the keyword. It is currently only active for Darwin targets.
It should also work at least for Linux targets, but only with
the GNU assembler (which is why it is not activated there)
+ test for this functionality
git-svn-id: trunk@12009 -
* do not overwrite left.location.register in second_int_to_bool() but use temp register when converting input value to C style truth values (i.e. 0,-1). With -Or enabled this register will be reused not containing the correct value anymore.
git-svn-id: trunk@10729 -
- Explicit typecasts like LongBool(byte_value) do not change ordinal value.
- Explicit typecasts like ByteBool(longint_value) do not change ordinal value and can lead to data loss if longint_value is outside of ByteBool range.
- Explicit typecasts like ByteBool(LongBool) handle type ranges correctly.
- Updated test tw10233.pp. It is passed by Delphi as well.
git-svn-id: trunk@10672 -
* Fixed sign/zero-extension in second_int_to_bool for all CPUs. x86 and pppc were not affected by this bug, but I fixed it for all CPUs for consistency.
* cg/tcnvint1 is passed on arm now.
git-svn-id: trunk@10669 -
size must happen without any mangling of the value (mantis #11027)
* moved checking for signed-to-unsigned (or vice versa) type
conversions in assignments from htypechk to ncnv (where there
was already code for similar checks) and added support for
bool_to_bool there as well
git-svn-id: trunk@10521 -
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 -
for qwordbool) + test:
o assigning true to such a variable now sets them to $ff/$ffff/$ffffffff
o these types are now all signed
o converting an integer type to a byte/word/long/qwordbool using an
explicit type cast keeps the integer's original value stored in the
bool, instead of forcing it to ord(true)/ord(false)
(mantis #10233 and #10613, implemented for all architectures, testsuite
tested for ppc32, sparc and x86)
* fixed some places where the rtl depended on longbool(true) having the
value 1
* extended several boolean tests (and adapted some to no longer assume
that byte/word/long/qwordbool(true)=1)
+ support for converting to qwordbool in second_int_to_bool for x86, ppc
and sparc
