{$modeswitch arraytodynarray} is active (mantis #35576)
o changed compiler to compile without this modeswitch
o added the modeswitch to a test that depends on it

procoptions even when it's through an array-of-const parameter
* always call create_varargs_paraloc_info() instead of create_paraloc_info()
in the former case, even when no varargs parameters are specified (because
on some platforms even some non-variadic parameters need to be passed
differently, such as on ARM with gnueabihf)
git-svn-id: trunk@41420 -
tcpuparamanager, very similar to the existing get_volatile_registers_XXX. The
new methods are called get_saved_registers_XXX, where XXX is the register
type ("int", "address", "fpu" or "mm")
git-svn-id: trunk@38794 -
"don't free even if not registered"; use for defs that may not be written
to a ppu file, but that must nevertheless survive the compilation of the
current module
* mark all defs created for para locations as "don't free even if not
registered", because we don't discard and recalculate all para locations
after a module has been compiled (since that's not needed)
o solves issues if the paralocations for a routine in the interface of
unit A are calculated while the implementation of unit B gets
compiled, and a new reusable type is allocated at that point which
is not used anywhere else (after r32160)
git-svn-id: trunk@32235 -
that the type of the parameters can be determined automatically
o added compilerproc declarations for all helpers called in the compiler
via their assembler name, so we can look up the corresponding procdef
git-svn-id: trunk@23325 -
getintparaloc + adapted all call sites of getintparaloc. This
led to a number of additional, related changes:
o corrected the type information for some getintparaloc parameters
o don't allocate some intparalocs in cases they aren't used
o changed "const tvardata" parameter into "constref tvardata" for
fpc_variant_copy_overwrite to make pass-by-reference semantics
explicit
o moved a number of routines that now have to call find_system_type()
from cgobj to hlcgobj so that cgobj doesn't have to start depending
on the symtable unit
o added versions of the cpureg alloc/dealloc methods to hlcgobj that
call through to their cgobj counter parts, so we can call save/restore
the cpu registers before/after calling system helpers from hlcgobj
(not implemented in hlcgobj itself, because all basic register
allocator functionality is still part of cgobj/cgcpu)

to and returning them from sub routines, in order to follow the JVM
specs to the letter (not checked by the JVM bytecode verifiers, but
checked by the Android DEX verifier)
* -> also zero-extend them again at the caller side after returning
from such a function
git-svn-id: branches/jvmbackend@18919 -
o primitive types are first boxed
o the parameter is passed inside an array of one class instance
o changing the parameter inside the routine (by assigning a value to it
like in Delphi.NET and different from regular Pascal code) will replace
this class instance (again boxing the value if required)
o on return, the class instance is extracted, unboxed if required, and
assigned back to the original location
o formal const parameters are handled without the extra array indirection,
since they cannot be changed
TODO: while writing tjvmcallparanode.handleformalcopyoutpara() I forgot that
calling getcopy on ttemprefnodes whose ttempcreatenode hasn't been copied
yet works fine, so that code is more complex than needed. Still have to
fix.

of functions at the caller side, since these will already be allocated
at the callee side
* added comment to cpupara explaining why we never allocate the function
result on the caller side and then pass it as an invisible parameter,
but instead always let the callee allocate it
git-svn-id: branches/jvmbackend@18420 -
o support for copying value parameters at the callee side if they were
passed by reference in hlcg
o JVM g_concatcopy() implementation for arrays
o moved code to get length of an array from njvminl to hlcgcpu so it can
be reused elsewhere as well
o export array copy helpers from system unit for use when assigning one
array to another
o some generic support for types that are normally not implicit pointers,
but which are for the JVM target (such as normal arrays)
* handle assigning nil to a dynamic array by generating a setlength(x,0)
node instead of by hardcoding a call to fpc_dynarray_clear, so
target-specific code can handle it if required
* hook up gethltemp() for JVM ttgjvm so array temps are properly
allocated
git-svn-id: branches/jvmbackend@18388 -
on the evaluation stack, while on the callee side they are placed
in local variables 1..n
o the jvm only supports call-by-value. call-by-reference parameters
will have to be emulated at a higher level
o similarly, ret_in_param() always returns false
o all function results are returned on the evaluation stack (both
on the caller and callee side)
