nutils.pas into virtual class methods of a new tnodeutils class defined
in ngenutil (global factory: cnodeutils), so they can be overridden by
architecture-specific implementations (required by the JVM backend)

(pushedparasize is already expressed in number of stackslots rather
than in bytes)
o when determining the number of stack slots to pop after calling a function
and not using its function result, round up the function result size to
the nearest multiple of 4 before determining the number os tack slots (to
correctly handle byte/word-sized results)
git-svn-id: branches/jvmbackend@18362 -
o self is encoded as "this" for javac compatibility
+ ait_jvar (for the above) and ait_jcatch (similar, for future try/catch
support) classes
+ support for smallset JVM type encoding (as int)
git-svn-id: branches/jvmbackend@18354 -
Jasmin assembler we use is a Java program, so the "assembler binary" is
java itself (which is a native program for the current host in any case)
git-svn-id: branches/jvmbackend@18350 -
o hlcgobj support in tcgsubscriptnode.pass_2 for JVM-required functionality
o slightly different handling for class fields for the JVM than for other
platforms: instead of adding a unit-level staticvarsym with a hidden name,
rename the original (unused) field and add the staticvarsym with the original
name to the object symtable. This is required because the JVM code generator
has to know the class the field belongs to, as well as its real name
o moved tprocdef.makejvmmangledcallname() functionality mostly to
jvmdef.jvmaddtypeownerprefix() because it's also required for mangling
field symbol names
* changed the interface of jvmdef from ansistring to shortstring because
all of its results are also used in shortstring contexts (and they're
unlikely to overflow the shortstring limit)
* "protected", "private" (without strict) and implementation-only symbols
now get "package" visibility instead of "public" visibility
git-svn-id: branches/jvmbackend@18349 -
since the definition-specific adorning of JVM mangled names is Jasmin-
specific, and such code has no place in symdef
* moved code to adorn JVM mangled names for Jasmin definitions to agjasmin
git-svn-id: branches/jvmbackend@18346 -
and skip comments (so it works again when -ar is used, because
tlhcgjvm.inc/decstack() insert comments in that case)
git-svn-id: branches/jvmbackend@18340 -
o changed type of opsize field of tcgcasenode from tcgsize into tdef,
and fixed compilation of other code generator units after this change
git-svn-id: branches/jvmbackend@18339 -
that's how these operations also work on other architectures
* fixed tjvmaddnode.second_generic_compare() for this new order
git-svn-id: branches/jvmbackend@18338 -
operation is 32 bit, not 64 bit (both in the compiler and in the
JVM)
* request a 64 rather than a 32 bit shift operation from tjvmshlshrnode
if the result is 64 bit (rather than in case shift value is 64 bit,
since as described above that never happens)
git-svn-id: branches/jvmbackend@18337 -
in case of -ar add to the assembler output the height of the
evaluation stack every time it's increased or decreased (to
more easily track missing/wrong inc/decstack() operations)
git-svn-id: branches/jvmbackend@18335 -
u64bit division/mod, and no overflow checking for divisions
(none yet for add nodes either, but that has to be implemented
in hlcgcpu rather than in the add-nodes themselves)
git-svn-id: branches/jvmbackend@18331 -
o handle them like for regular classes (return a class instance,
although this is technically not true since they don't return
anything; will be changed in the future)
o because of the previous point, make sure that we handle the
"function result" properly and don't pop too many values from
the evaluation stack when calling one constructor from another
o added "extra_pre_call_code" method used by njvmcal to insert
the "new" opcode to create the new class instance before
calling a constructor
o when a constructor does not call any other constructor (inherited
or otherwise), automatically insert a call to the inherited
parameterless constructor as required by the jvm standard)
TODO: check that *if* an inherited or other constructor is called
from another constructor, that it does so as the first statement/
call
git-svn-id: branches/jvmbackend@18328 -
renamed refactored routine to do_release_unused_return_value()
which by default releases temps, and if something else needs to
be done override (and call inherited if temps may have to be
released)
git-svn-id: branches/jvmbackend@18327 -
name of a Java class (package/procname), extracted from jvmdef
* several fixes to jvmmangledname (po_has_importdll only applies to
unit-level procedures, replace incomplete mangling of class type names
with call to jvm_full_typename()
git-svn-id: branches/jvmbackend@18326 -
support), passed through to original ncgutils version in thlcg2ll
+ thlcgobj.location_force_mem() implementation
* order parameters for jvm similar to those for i386 without fixed_stack,
so we don't need temporary paralocations
* converted most of ncgcal to thlcg
* disabled special handling for virtual methods for jvm in ncgcal, as all
invocations are name-based there
+ njvmcal with special jvm callnode support:
o always move the function result into a memory temp
o when freeing an unused function result, use a_pop(2) and adjust
the internal evaluation stack height counter
o after the call instruction, adjust the evaluation stack height counter
by subtracting the number of the pushed parameter slots, adjusted for
the slots taken up by the function result
git-svn-id: branches/jvmbackend@18325 -
o support formal external definitions (like for objcclass)
o allow specifying an "import_dll" for external Java classes, which can
be used to specify the Java package name (like the dll for cppclass)
o take the package name into account when mangling the Java class name
o several messages that were specific to Objective-Pascal classes have
been generalised because they also apply to Java classes, same for
several compiler function names
o disabled some proccall directives for Java, but more needs to happen
(Java methods are always either instance-virtual or class-static)
git-svn-id: branches/jvmbackend@18319 -
FindFileInExeLocations()
* search for jasmin.jar using FindFileInExeLocations and properly
build the java command line, so jasmin can be called successfully
by the compiler
* properly create separate assembler files for each class, and
correctly specify the class name and superclass for each class
(units themselves are still hardcoded to descend from java.lang.Object)
git-svn-id: branches/jvmbackend@18318 -
as well as insert_regalloc_info_all()
+ "register" allocator for the jvm target, which simply replaces every
virtual register with a temp. This is done for all register types in
one pass, so that the temps can be easily reused without worrying
about conflicts. Small optimisation: alloc/store/dealloc/load
sequences for a single reg are removed (many of these are generated
because most cg nodes return their value in a register which is then
immediately consumed by the parent)
* map addressregisters to integer registers with size R_SUBD, because
they require one stackslot (the subregister type is used by rgcpu
to determine the size of the temp it has to allocate)
git-svn-id: branches/jvmbackend@18316 -
handle vectorfpu (floatdef->MMREG) and softfloat (floatdef->INTREG)
+ thlcg.getregisterfordef(), which uses def2regtyp() to allocate a register
appropriate to hold values of that tdef type
+ generic thlcg.location_force_reg() implementation. Note that for
low-level code generator targets it may be slightly less efficient than
the implementation in hlcg2ll (from ncgutil) because it does not play
any tricks with the register or location size, or with reference offsets,
to truncate values
