code generator translation (as done by some ABIs, such as most x86-64
platforms and darwin/i386)
-> all regressions in jvmbackend branch for darwin/i386 fixed

oo_has_destructor is inherited from the parent class (because it
influences whether a VMT is required for TP-style objects),
so use separate oo_has_new_destructor flag instead
git-svn-id: branches/jvmbackend@18797 -
accidentally committed a long time ago (it was done to test the
generic hlcg conversion -- which in a sense was good, because it
just uncovered the bug fixed in svn trunk r18792, i.e. a bug
not specific to the hlcg conversion)
git-svn-id: branches/jvmbackend@18795 -
platforms after r18561 (newly introduced element-to-open-array type
conversion retains the value location on those platforms)

unicodestring = java.lang.String. The reason this was the default in
the past is that this was the first string type that was implemented,
and without it being the default most code involving string operations
would fail. Now the default strings types are the same as for other
targets
+ new {$modeswitch unicodestrings} directive, that when activated
*together* with {$h+},
1) changes char into an alias for widechar
2) changes string into an alias for unicodestring
3) changes the preferred string evaluation type (in case of uncertainty)
to unicodestring
{$modeswitch unicodestrings} with {$h-} does not change anything at all
regarding the string type (it still changes the char type)
+ new uuchar unit that redefines char as widechar, and which is automatically
included by the compiler if {$modeswitch unicodestrings} is enabled

resource compilation happens and that the standard FPC resource
helpers are not available. What happens is that all files specified
in {$r xxx} statements are packed together into an <appname>.jar
file, under the namespace "org.freepascal.rawresources". They
can be loaded using the java.lang.Class.getResource/getResourceAsStream()
api
git-svn-id: branches/jvmbackend@18776 -
a generalized version of the formal var/out/constref support (this
also fixes passing string[xyz] expressions to non-formal var/out/constref
parameters)
git-svn-id: branches/jvmbackend@18774 -
also handle non-formal parameters
* do not copy in the original value in handleformalcopyoutpara() if it's
an out parameter
git-svn-id: branches/jvmbackend@18772 -
respectively to 0 and 255 (both generally require one memory load);
the setconstn complexity of 255 also caused the node cse to replace
them with temprefn in some cases, which wreaked havoc with the JVM
practice of determining whether in-expressions can be handled by
the generic code generator or not
git-svn-id: branches/jvmbackend@18756 -
variables, class/record fields and arrays with enumtype(0) on
creation, so that using them without explicitly initializing them
doesn't cause a null-pointer exception. If enumtype(0) is not a
valid enum, they are not initialized (and since they wouldn't have
a valid value on native targets either in that case, an exception
on use is acceptable)
git-svn-id: branches/jvmbackend@18755 -
constructors, inherited virtual class methods) when deciding which
overloaded version of a routine to call. Otherwise they can change
which variant is called compared to code on platforms where such
implicit methods are not added
git-svn-id: branches/jvmbackend@18752 -
valid_for_assign() if that routine returns true (in some cases,
it's used to simply check whether we could possibly put it on
the assignment side)
git-svn-id: branches/jvmbackend@18751 -
* added runerror number to JVM FpcRunTimeError exceptions
* enabled calling errorproc when a run time error occurs on the
JVM target
git-svn-id: branches/jvmbackend@18749 -
cpu64bitaddr is not defined rather than if cpu64bitalu is not
defined, because whether or not operations should be 64 bit by
default depends on cpu64bitaddr, and even if a cpu can perform
64 bit alu operations, 32 bit ones are likely faster
git-svn-id: branches/jvmbackend@18748 -
in the system unit for easier debugging)
* disabled a bunch more feature flags by default for the JVM target
* incorporate modified version of inc/systemh.inc (split into two parts:
jsystemh_types.inc and jsystemh.inc, because some of the types are
required for the declaration of the shortstring/ansistring/set/...
classes, which in turn are required for the routine declarations) and
inc/system.inc (as jsystem.inc)
o moved some routines around from old to new locations based on where
they appear in the common files
o added a number of defines that allow skipping more common implementations
in case a platform-specific one is already available
* all base classes (AnsistringClass etc) are now descendants of
JLObject rather than TObject, because their declaration is now parsed
before TObject is known (and there's no need for them to inherit from
TObject)
* incorporate modified version of inc/system.inc
* use the common version of generic.inc, currh.inc, gencurr.inc and
genmath.inc (with small modification to those files)
+ addition of quite a bit of system unit functionality (halt, runerror,
random, round, str() for integer types, abs, odd, endian swapping helpers,
bit scanning, trigonometric functions, ln, exp, ...)
o round()/trunc() for comp-types has been renamed trunc_comp() on the
JVM target because their JVM signature conflicts with trunc(currency)
o the unsigned versions of swapendian() and other endian helpers are not
available on the JVM target because of JVM signature conflicts
git-svn-id: branches/jvmbackend@18746 -
+ include mathh.inc in the system unit, implement most routines based
on java.lang.Math, and use (an unmodified!) genmath for the rest
- removed now obsolete jmathh.inc (was partial copy of mathh.inc)
- removed commented out overrides for several math routines in
njvminl (doesn't make sense to handle them inline in the compiler)
git-svn-id: branches/jvmbackend@18742 -
with wrapper calls, because the parameter nodes are already bound to the
paravarsyms of the current procdef so simply replacing the procsym and
procdef is not enough
