+ basic target information for jvm target (assembling/linking
helpers are still dummies for now)
+ basic jasmin assembler writer
+ cpunode and cputarg units to include the target units in the
compiler
git-svn-id: branches/jvmbackend@18309 -
+ added arrayreftype field to treference for the jvm, because
array loads have to be performed using special instructions,
so this information has to be passed on to the code generator.
This information will have to be added in t(cg)vecnode.
* moved concatenating the generated code for a procedure to the
al_procedures list to thlcg.record_generated_code_for_procdef(),
which is overridden by jvm/hlcgcpu to attach that code to the
procdef it belongs with. The reason is that a Java class file
can only contain code for one class, so we have to write out
the assembler grouped per class instead of in the order the
routines appear in the source code
* also committed forgotten changes in psub after moving the
register allocator initialisation to hlcgobj

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)
git-svn-id: branches/jvmbackend@18306 -
longer aligns the temp offset in case it's odd (not required for
jvm)
* ignore the "def" argument in alloctemp() for the jvm since all stack
slots can be reused for anything there, and reformatted its alloctemp()
git-svn-id: branches/jvmbackend@18297 -
(single, double, string, widestring), basic constructors,
spilling_get_operation_type() implementation
o special: O_MOV_SOURCE/O_MOV_DEST don't make sense for this target,
since it's stack based
git-svn-id: branches/jvmbackend@18294 -
o special things:
* no tasmcond (conditions are currently encoded in opcode names,
may be changed later)
* no actual registers, just a couple of fake ones to indicate
the locals stack and the operands/evaluation stack
* no registers for the return value; they're returned on the
evaluation stack; may be handled like the x87 in the future
git-svn-id: branches/jvmbackend@18291 -
* made ttgobj.create virtual, added a "tgobjclass: class of ttgobj = ttgobj"
variable and use that one to instantiate new temp allocators
* created ttgjvm descendant that only allows allocations of 4 or 8 bytes
(rounding allocations < 4 bytes up to 4 bytes), and that divides the
offsets/sizes by 4 so we get stack slot numbers
