(the ABIs that prescribe special treatment for aggregates with one
scalar element don't either, since a "union containing a single scalar"
is not the same as a scalar)
* fixed passing record with a single float field on PowerPC/AIX abi's
* several changes to cgobj and ncgutil to correctly deal with transfering
such records between integer and floating point registers
git-svn-id: trunk@15416 -
tai_const.size (fixes internalerror when using the internal Mach-O
assembler with DWARF debug info, patch by Dmitry Boyarintsev, mantis
#16640)
git-svn-id: trunk@15391 -
* fixed record parameter passing (all records <= 4 bytes passed
by value, records > 4 bytes by reference)
* fixed procedure of object parameter passing (handle like tmethod
record) (mantis #16520)
* fixed aligning parameters for EABI (it does not depend on the
parameter size, but rather on its alignment, and also align in
case a parameter that we wanted to pass via registers has to be
passed via the stack because we ran out of registers)
git-svn-id: trunk@15390 -
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 -
x86-64 platforms (except for win64, which uses another ABI and which
already complied to it) + test
* fixed returning records containing 1 single or double field on darwin/i386,
these have to be returned via ST0 instead of as a regular record
* added support for LOC_FPUREGISTER and LOC_MMREGISTER in several places
where they can now occur due to the previous two changes
* made a few internalerrors unique
git-svn-id: trunk@15368 -
look at paraloc^.size rather than cgpara.size, because e.g. a 32 bit
record (-> cgpara.size=OS_32) may have to be passed via a
LOC_MMREGISTER (-> paraloc^.size=OS_F32 or OS_M32)
git-svn-id: trunk@15365 -
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
git-svn-id: trunk@15350 -
tobjectdef.needs_inittable returns false for classes nowadays (and already
since quite some time)
* nevertheless replaced all usages in the compiler of x.needs_inittable with
is_managed_type(x) (in case some other condition is added again in the
future) and removed all remaining accompanying "and not is_class(x)"
checks
git-svn-id: trunk@15320 -
returns true for variants and those aren't refcounted
* also allow tempnodes for pointers to managed types to be put in
registers (not sure why it was disabled, and there are no
testsuite regressions by enabling it)
git-svn-id: trunk@15319 -
ncgutil it can be used elsewhere too
- removed the code that checks for 64 bit integer types in the float
para loading code, since is_64bit() can never return true for a
floatdef
git-svn-id: trunk@15318 -
(it means that if the pointer is nil, the value is invalid; that's not the
case here, it just means that they are empty)
* generate upper bound of -1 (for dynarrays) or 0 (for ansi/unicodestrings)
if they are not allocated, so gdb can calculate their length as 0
(all based on tips by Jan Kratochvil)
git-svn-id: trunk@15288 -
+ added extra sanity check when parsing a type constant set
+ added brackets around or/and expression to make it clear what the meaning
is
git-svn-id: trunk@15269 -
search for an existing section with the same content first. This reduces the
generated executable size, compilation time and memory usage of the compiler
git-svn-id: trunk@15103 -
treated as a regvar from pass_1 to the code generator, because this
can always occur with a function result from a called function (in
case the ABI prescribes returning certain records in registers)
(mantis #16163)
git-svn-id: trunk@15101 -
to the parser, so that it only looks at what the programmer wrote rather
than at all statements that the compiler may generate internally
(mantis #11619)
+ several tests for {$x-} mode
* modified tenumerators1 so it compiles without extended syntax enabled
(to check for..in with {$x-})
git-svn-id: trunk@15075 -
- add own symbol table for enumeration to store enumeration elements
- reimplement enumeration member traverse using symbol table instead of firstenum/nextenum - that members are removed
- implement TEnum.Element access syntax - element is searched in the enumeration symtable in this case instead of global/local symtables
- implement {$SCOPEDENUM ON/OFF} local switch
+ tests
git-svn-id: trunk@15051 -
match but the source range does not fit in the dest range
(related to mantis #16023)
* don't give a "potential range error" when converting between
s80real and sc80real, since even though the size may differ,
the represented range does not
git-svn-id: trunk@15044 -
- add an option to skip varspez during parameters comparison
- skip varspez comparison when searching a property reader candidate if $VARPROPSETTER is ON
git-svn-id: trunk@15020 -
passing any value to that parameter which has the same size as the
parameter (it basically acts as if there is an explicit type conversion
to the parameter type around the value at the caller side). If a procvar
has an univ parameter, all procvars whose corresponding parameter
has the same size as that univ parameter are similarly compatible.
This transparent compatibility can however cause crashes in case of
of the procvars when one of the types is passed on the stack and the
other isn't (because then the called routine will a) load the parameter
from a wrong location and b) pop the wrong amount off of the stack at
then end). Therefore FPC will warn in most cases where this can happen.
(mantis #15777)
