pd.struct to determine whether a directive is allowed or not, because
pd.struct is also set for nested routines (also has to be changed for
objcclass)
git-svn-id: branches/jvmbackend@18608 -
parentfpstructs unique (a single procsym can have multiple overloaded
procdefs, but a single procdef is unique)
git-svn-id: branches/jvmbackend@18607 -
so that the result type of random dynamic array expressions doesn't suddenly
get changed into open array (causes internalerror if the size is requested),
and instead simply change the conversion type to tc_equal
git-svn-id: branches/jvmbackend@18605 -
mangled name handling ansistring rather than pshortstring based (required
for JVM target; little effect on speed, some extra memory usage)
git-svn-id: branches/jvmbackend@18597 -
o support for JVM arrays in JVM addrnodes and derefnodes (so we
can take the address of var parameters to store them in the
parentfpstruct and later dereference them)
o process loadnode.left also in tjvmloadnode.pass_generate_code() when
handling var-parameters
git-svn-id: branches/jvmbackend@18593 -
o since the JVM target has no stack/framepointer that can be passed
on to nested routines, all local variables and parameters accessed
from nested routines are grouped into a local record whose address
is passed to nested routines. The same technique is also required
for LLVM in the future
git-svn-id: branches/jvmbackend@18588 -
creating procdef's JVM mangled name, because this situation can also
arise in case there's a simple error in the source code
git-svn-id: branches/jvmbackend@18586 -
helper
* never call a helper for classrefdefs (in that case we have to load the
classrefdef itself, not the classrefdef for the class representing
classrefdefs)
git-svn-id: branches/jvmbackend@18575 -
(non-dynamic arrays, records, shortstrings)
- removed the ability to typecast such types directly into related class
types, you have to use the @-operator first now to get a pointer to
the type
o updated the RTL and internal compiler code to properly use this
new convention
o allowed removing several special cases from
tjvmtypeconvnode.target_specific_general_typeconv(), and that
method can probably be removed completely over time
* no longer give compile time errors for pointer-related typecasts that
will fail at run time, because the checking was too complex and could
be worked around via actual pointer typecasts anyway
* removed some unnecessary checkcast operations (for shortstring/
shortstringclass)
git-svn-id: branches/jvmbackend@18574 -
* move the incstack() from a load before the potential "and" to
zero-extend, so that the maximum stack height get calculated
properly
git-svn-id: branches/jvmbackend@18565 -
o support for ansistring constants. It's done via a detour because the
JVM only supports UTF-16 string constants (no array of byte or anything
like that): store every ansicharacter in the lower 8 bits of an
UTF-16 constant string, and at run time copy the characters to an
ansistring. The alternative is to generate code that stores every
character separately to an array.
o the base ansistring support is implemented in a class called
AnsistringClass, and an ansistring is simply an instance of this
class under the hood
o the compiler currently does generate nil pointers as empty
ansistrings unlike for unicodestrings, where we always
explicitly generate an empty string. The reason is that
unicodestrings are the same as JLString and hence common
for Java interoperation, while ansistrings are unlikely to
be used in interaction with external Java code
* fixed indentation
git-svn-id: branches/jvmbackend@18562 -
so it can be intercepted by the JVM backend (it has to create an actual
array)
+ JVM support for the elem_2_open_array hook
git-svn-id: branches/jvmbackend@18561 -
