This reverts commit c2ff85ac5b.
That change duplicates the logic of tstatementnode.simplify in
tblocknode.simpify in a very complex way, and in case of issue #39336 results
in adding a non-tstatementnode in a tblocknode, which is illegal. If
tstatementnode.simplify cannot catch all cases, then that one should
preferably be improved instead (and if not possible, we can look into
catching those edge cases in tblocknode.simplify rather than duplicating
everything).
Resolves issue #39336
than when the first temprefnode to it gets processed. Solves the issue
the foreachnodestatic processes the tempinitcode when seeing the
tempcreatenode and ignores it when seeing temprefnodes, even though
it may actually be executed/generated for the temprefnode. It's
impossible to easily process it for the "correct" temprefnode
(since there may be multiple temprefnodes for the same tempcreatenode)
o fixes tarray12 for Darwin/i386 and Linux/i386

that expects an open array of byte, and use it for all sets
o since all sets need to be typecasted to an array type of the appropriate
size, we'll get a compilation error in case this needs to be done and
that also tells us at the same time that the ppu version will need to
be increased
* enabled {$packset 1} for the compiler, as this is now safe with the above
changes
git-svn-id: trunk@43407 -
Allows compilation of compiler using -dDEBUG_NODE_XML
which will generate a NAME-node-dump.xml file for each
unit, program or library compiled,
containing a XML description of the nodes handled during
compilation of the unit, program or library.

(needed for LLVM, where we need two copies of the finally code: one in case
an exception occurs, and one in case none is raised)
o also first finalize parameters and only then code generator temps, since
in theory the former could create more of the latter
git-svn-id: trunk@40345 -
and getters for the ttemp*node classes instead
o this will allow descendants to prevent certain flags from being added
or removed. E.g. for LLVM, certain temps must never be put in registers
because it cannot typecast a value in a register from a non-record/array
type to an array type without forcing it to memory (so if that is done
on an lvalue, the result will be written to the memory temp instead of
to the register)
git-svn-id: trunk@34358 -
release the source location in case it was also a temp. Reason: we
don't increase reference counts when assigning to a ti_const (they are
like const parameters), so the original value must stay alive until
the ti_const temp is freed
o free the original data in the ttempdelete node for the ti_const temp
o don't increase reference counts when assigning composite types to
ti_const temps either

If assembler block has no modified register list, it is still handled in pass2, by allocating all volatile registers (not only the integer ones as before).
git-svn-id: trunk@30011 -
e.g. being a const parameter or immutable temp. values), managed types like dyn. arrays, new string types and interfaces can be kept in registers.
git-svn-id: trunk@24953 -
o support for the new codepage-aware ansistrings in the jvm branch
o empty ansistrings are now always represented by a nil pointer rather than
by an empty string, because an empty string also has a code page which
can confuse code (although this will make ansistrings harder to use
in Java code)
o more string helpers code shared between the general and jvm rtl
o support for indexbyte/word in the jvm rtl (warning: first parameter
is an open array rather than an untyped parameter there, so
indexchar(pcharvar^,10,0) will be equivalent to
indexchar[pcharvar^],10,0) there, which is different from what is
intended; changing it to an untyped parameter wouldn't help though)
o default() support is not yet complete
o calling fpcres is currently broken due to limitations in
sysutils.executeprocess() regarding handling unix quoting and
the compiler using the same command lines for scripts and directly
calling external programs
o compiling the Java compiler currently requires adding ALLOW_WARNINGS=1
to the make command line
git-svn-id: branches/jvmbackend@20887 -
* eliminate warnings in compiler (i386 & i368->x86_64) and minor refactorings
- comment out unused vars and types
- comment out unneeded comparisons (Longword <=> 0)
- suppress some "comparison always true|false" warnings
- tweak visiblity sections
